Blu-Ray technology is the next generation of optical disc format developed by the Blu-Ray Disc Association(BDA) and major developers of consumer electronics, computers, and media manufacturers around the globe. It seems that human technology in robotics, computers, NanoTech and BioTech are coming together to make the species their own god. From my experience working for corporate aliens, from what others have told me, and from numerous articles on the internet, I have come to the conclusion that managers of many corporations show considerable disrespect to their technology workers.

Are we searching for unnecessary information and over loading ourselves? When so much information was not available to us, we could live, isn't it? Then why do we search for any and everything online? Does that make our life better? In the earlier days, people took time to write letters to each other. Some people might think that carpal tunnel syndrome is a new condition of the information technology age, born from long hours of computer keyboarding, but carpal tunnel is not new, it just seems to appear more often because the nature of work has changed. There is a general belief that working for extended periods of time using a computer will lead to an increase in carpal tunnel syndrome, and that jobs such as data entry lead to higher risk of carpal tunnel syndrome.

It would seem that today's nascent Internet technology compromises the functional power of the client/server model in their leasing software; complex algorithms required to amortize income or calculate yields appear hard or even impossible to replicate on a browser. When it comes to workflow software just think of having a simple to-do list at your hands wherein through the workflow software, that to-do list can now also be accessible by other employees from your company through the company network.

If you're not one of the computer-savvy website builders out in the realm of the World Wide Web, or a presentation developer at a Fortune 500 company, think about this: Over 90% of all computers in the world have Flash Player installed in them to adequately view websites and other mediums that incorporate Flash into their pages. Pen drives, chip sticks, thumb drives or USB keys are other terms given to USB flash drives and consist of a small printed circuit board encased either in sturdy plastic or metal; the latter makes flash drives even more hard-wearing. Essentially the same, USB flash drives are available in a variety of styles and colors and even with various uses but all work the same.

If we can drop off 20,000 rats some with electronic pulse devices strapped on them in 20 different locations we can over whelm the enemy, wake up the communication and start movement and then attack after just prior to the coordinated attack we send our an electronic attack to kill the communication and electronics of the enemy. Whole house protection devices can be utilized in homes of almost any size and they provide blanket coverage for all people within the home and as such are highly recommended, especially for families with children, for the overall coverage it provides.

Everyone who has an ISP, understands, or at least knows about how hackers use viruses, Trojans and other web nastiness, to infect and mess up your computer. Recently we read about the Hackers annual convention this year in Las Vegas, DEFCON. It seems that as days go by people are becoming more and more concerned with the security of their money and protecting their personal and financial information from identity thieves and hackers. To be safe is to stay with the latest antivirus and spyware.

Many installers of low voltage outdoor lighting systems wonder how many lights can be added to the system before it is overloaded. Most commercial and industrial low voltage system dealers, vendors and integrators have invested substantially in training their technicians on the technical aspects of installing, maintaining and operating the systems they promote. For commercial and industrial low voltage installations, the field wiring, device mounting, and panel installations are a major portion of the installation.

If you are upgrading your home electrical service, you should consider the addition of a "whole house" surge protector. If you are contemplating a major remodel, the addition of a room or garage, or a new kitchen you should consider upgrading your electrical service. When facing a home repair job that needs electrical home improvement, you should consult a professional, or hopefully take a class at your local building supply store for the best results.

Privacy may be the biggest reason of all for you to invest in a computer headset.

MODEMS: Modems are the devices, which are used to translate the digital data into the analog format and vice versa.

Go Online to Buy Hot Consumer Electronics for the Holidays

2007-11-16T03:43:00.000-08:00

As in recent years, experts are forecasting that consumer electronics will top wish lists in the upcoming holiday season. And, although some shoppers continue to favor brick-and-mortar stores, an increasing number of consumers are finding better prices and greater selections of consumer electronics through online stores.

There are three categories of consumer electronics that are forecast to be especially hot this holiday season:

Gaming Systems

The recent launch of Halo 3 left no doubt among entertainment industry experts that video games and video game consoles can rake in more money than Hollywood movie premieres. With over $3 million in sales the first week, Halo 3 - the Xbox 360 signature game - dealt Microsoft a winning hand.

But the Xbox 360 isn't the only gaming system set to heat up during the holiday gift giving season. With its enhanced physicality and interactive community, Nintendo Wii is still considered the breakout gaming system of the decade. From the compelling Wii characters to the dexterity-challenging Nunchuk, every aspect of the Nintendo Wii is engaging and enchanting.

Although in some circles Sony's PlayStation has been left holding the bag, PS3 gaming systems are still hot commodities, especially for families with children. As some of the other gaming systems have skewed their video game releases to the teenage and adult markets, PS3 and PS2 systems have remained home to a vast array of kid-friendly games.

Cell Phones

Although cell phones are ubiquitous, they continue to be in demand. And, despite the hoopla associated with this year's launch of the innovative Apple iPhone, this holiday season will find most shoppers buying established cell phone brands like Nokia, Samsung, and Motorola.

Music and Video Players

When it comes to consumer electronics and the holidays, more people than ever before will be unwrapping music and video players. Apple iPods are expected to be in high demand, as will portable DVD players. And, with an increasing number of people becoming familiar with DVD recorders' multitude of features, DVD player/recorders will also be hot commodities this holiday season.

Buying Consumer Electronics Online

Because online stores don't have the overhead expenses associated with retail brick-and-mortar stores, they are often able to offer the most popular consumer electronics at rock bottom prices. Plus, online store offer the added bonus of allowing consumers to comparison shop in order to find the best deal on gaming systems, cell phones, and music and DVD players.

For example, some online stores will offer a variety of video games bundled with an Xbox 360, which can literally save consumers hundreds of dollars. Aside from bundled systems and other bargains, there are other factors to consider when choosing an online store to buy consumer electronics. These factors include real-time ordering and online inventory (so your gift won't be stuck on backorder), warehouse shipping (rather than having to wait for a middleman to ship the merchandise), and exceptional customer service (such as timely communication and non minimum purchase requirements).

When you find the right store, shopping online for consumer electronics can be a breeze - and a bargain!

Luxe Electronic Gadgets Review

2007-11-16T03:41:00.000-08:00

There are so many esoteric, eclectic electronic gadgets that it is difficult to separate the practical and purposeful from the frivolous and senseless. And when tastes and personal preferences are factored into the mix, it is not as simple as separating gold and tin into two discernible piles.
There are entire personal-communication systems that fit into mobile phones. Sunglasses and wristwatches now are multidimensional communications and entertainment products. Mobile phones not only serve as entertainment centers and GPS navigational systems, the units also are viewed as jewelry and complementing accessories to one's fashion persona.

Apparently, Baskin & Robbins was really onto something when it decided to offer as many flavors as possible and to treat each tasty twist with the same reverence usually reserved for vanilla and chocolate. B&R was among the first firms to grasp that true luxury embodies a wide berth of available options. If something is made well, it will appeal to consumers of discerning tastes. The marketplace for electronic gadgets and games is truly a phenomenon of the 21st century.

We eat blueberries and talk into BlackBerrys. It is difficult to say whether any gadgets or accessories will amaze and enthrall us like the abacus did the Babylonians back in 300 BCE. While, abaci, which are still in use today, have endured for centuries, the eras of eight-track tape players, rotary-dial telephones, and VCRs are already ancient history. Does anyone still remember when mobile phones were as large as one of Shaquille O'Neal's sneakers, or when television sets did not come with remote controls?

The ever-changing landscape of new electronic gadgets and games is a byproduct of modern technology that is evolving faster than ever. The Luxé Electronic Gadgets Review plugs into today's latest wizardry. However, do stay tuned for upgrades, enhancements, and new product introductions throughout the year.

When it comes to mobile phones with intelligence, the BlackBerry line is summa cum laude with its front-row bleeding-edge technology. After all, it is a handheld mobile phone that works like a multi-port personal computer. And if that isn't enough to prompt a wow from the galley, the new BlackBerry Pearl 8100 is smaller and sleeker than its magnificent predecessors. Aside from being a phone that allows international roaming between North America, Europe and Asia Pacific, it comes with multimedia capabilities and 64 MB of memory, which is easily expandable.

Wearable electronics sounds like something movie characters like Batman or James Bond might wear. Although the terminology possesses a futuristic, science-fiction tone, it accurately describes intelligently designed multiuse products, such as the O ROKR. The O ROKR is Oakley's fourth release of a pair of eyewear with a built-in mobile phone and an MP3 player. It is Bluetooth-driven eyewear. The O ROKR is a collaborative effort by Oakley and Motorola. The O ROKRs come in three distinct colors, and there are stylish versions of it for both men and women.

V-Moda presents "hearwear" that dazzles the eyes, perks the ears, and piques the interests of both fashion and music aficionados. The Modaphone Hearwear collection is a series of fashionable earphones with the sparkle of jewelry and the clarity of high-end earphones. There are four models. Each model is made from super-soft silicon with fittings that are offered in three sizes. The fabulous four are individually known as the Bass Fréq, the Vibe, the Remix M Class, and the Modawrap. The earphones are compatible complements to Apple's iPods, Microsoft's Zune, and various other MP3 players.

It is all in the numbers. Escort Radar manufactures the best radar/laser detectors, as the company owns over 85 percent of all radar and laser patents in use. Radar/laser detectors are legal to use in 49 states. Virginia and Washington, DC, are the only exceptions. With all the coupes, roadsters, sedans, and even SUVs capable of accelerating beyond 150 mph smoothly and effortlessly, it is easy to see how even the most responsible driver could err at a most inopportune time. Escort Radar's Passport 8500 X50 circumvents such mishaps from occurring.

Sony's S2 Sports Walkman MP3 Player is a fit gift for any athlete on the list. The two-gigabyte model stores up to 1,350 songs, and it plays up to 18 hours on an embedded battery that provides three hours on three-minute charge. It also contains an FM tuner for alternate listening choices to get through the workout time. The S2 is lightweight and has a bright, easy to read organic electroluminescence display.

It came as no surprise that when Motorola wanted to glitz out its RAZR V3i that a call was placed to the glamorous team of Domenico and Stefano to add the D and G magic. These guys could make cat litter glitter. So, ascending a streamline, renowned luxury cell phone to jewelry-level status would be a golden opportunity for them to leave another mark of distinction.

As long as the road is in North America, getting lost while driving will not happen if there is a StreetPilot in the vehicle. This GPS-satellite-navigational system, which is no larger than a baseball, is guaranteed to always pitch straight info to drivers. Plus it can easily be removed from one vehicle and placed in another, as it securely attaches to windshields with a suction cup. It is a perfect gift for the soon-to-be rich student, or an ideal addition to the classic car of a bygone era.

Having knowledge at your fingertips makes for a great metaphor. Having knowledgeable info conveyed instantly from an easy-to-use handheld device makes for a very innovative and entertaining product. The SkyScout by Celestron, with its advanced GPS technology, can be used during the day or night. Turn it on and its built-in menu provides operating info simple enough that even adults can operate it without muss of fuss.

When hip-hop, country or rock artists put out a song that has universal appeal beyond its anticipated audience, the hit song is a crossover. So, if a cell phone contains 140 grams of solid gold and is studded with diamonds, would it be a crossover into the jewelry marketplace as well as being a cell phone? There are so many people observed daily constantly holding cell phones against their ears. Many of these sleek machines could easily be mistaken for over-sized earrings. The Illusion, which is GoldVish's sparkling collection of personal luxury communication devices, is for real.

The Sony Ericsson Bluetooth Watch MBW-100 is a very practical, intelligent device that hits the underbelly of anyone who has ever imagined being a super sleuth or a suave secret agent like James Bond. The MBW-100 is a wristwatch with Bluetooth technology. When used with its wireless Bluetooth headset, the sophisticated wristwatch manages calls and music as simply as checking the time. This is a must-have for all lovers of bleeding-edge communications technology.

The thought of installing a telephone in one of the most intimate rooms in the house once left us bewildered, but this takes the cake. The iCarta dock from Atech Flash mounts easily onto the wall, charges your iPod while playing music, and features four integrated moisture-free speakers, which deliver exceptional clarity and high quality sound. The cost of replacing the NY Times for some Top 40 runs 100 dollars.

Since so many cell phones come equipped with MP3 capabilities, it only makes sense to make a dock designed with Bluetooth® Technology. The Altec Lansing T515 wireless speaker system features a speakerphone, a headset with a microphone, and a Bluetooth frequency up to 30 feet. Just a touch of a button allows you to easily switch from your favorite song to any incoming calls you receive.

The Altec Lansing T515 is priced at 150 dollars.
From business professionals to aspiring musical artists, the MicroMemo turns your second generation iPod Nano into a portable, pocket-sized recording studio. You can capture audio using the flexible, detachable microphone and import it onto your computer where you can edit it later. With this little device you can record interviews, meetings, lectures, lyrics, or even your grocery list. The MicroMemo is priced at 60 dollars.

Sony MDR EX71SLB Fontopia headphones black deliver first-rate sound quality together with enhanced bass, all packaged in a super-light in ear design. This makes the Sony MDR EX71SLB Fontopia headphones black a significant step up from the standard budget headphones that are currently available.

In addition to the enhanced features of the MDR EX71SLB Fontopia headphones, they carry a bargain price tag, available for around £25 at the time of writing, making these headphones superb value for money.
As with most Sony headphones, the MDR EX71SLB Fontopias are designed in a classic modern style, in black and silver. The super small 9mm drivers give a very comfortable fit, and include the sonic isolation of soft silicon ear buds. The snug in ear fit allows for better sound quality as any background noise in reduced. A significant problem with a lot of ear bud style headphones is they are poor fitting, allowing ambient noise to leak in. This in turn leads you to turn the volume up to hear what you are listening to and can lead to hearing damage. The package also includes three sizes of ear buds giving the flexibility to fit a full range of sizes of ears, a 400-kj/m3 a Ultra-High-Power Neodymium Magnet, a hard carrying case, one meter extension cord, and an earbud holder.

Features of the Sony MDR EX71SLB Fontopia Headphones Black include:

# In ear design fits snugly yet comfortably inside the ear allowing you to enjoy music while excercising.
# The first closed-type Fontopia design from Sony reduces ambient noise and helps generate powerful, resonant bass response.
# New, super-small 9 mm drivers create powerful audio with space left over for the sonic isolation of Sony's newly-designed silicon ear buds.
# Soft, ergonomic silicon ear buds decrease background noise from outside, giving a comfortable fit even when worn for extended periods of time; the ear buds are washable, removable and replaceable.
# Trendy neck-chain cord.
# Gold-plated mini-plug for outstanding corrosion resistance, excellent conductivity and low noise.
# Sleek, compact case tidily stores the ear-buds and headphone cord when not in use. With a colourful purple design, the high-impact case is ideal for carrying in your pocket or a backpack.
# New case design minimizes cord tangles; partial winding can shorten the effective cord length during use

Whether you are replacing the headphones supplied with your iPod or you are looking for a great value pair of headphones for your portable music player the Sony MDR EX71SLB Fontopia Headphones Black are well worth considering.

Salvation Helicopters – As Seen On Tv!

2007-11-15T04:32:00.001-08:00

The new Salvation Helicopter is a lightweight radio controlled micro helicopter, which has been featured on the new reality TV show, “Tycoon” on ITV1. This article aims to give you more information on micro rc helicopters, they are great fun to fly indoors, and Salvation helicopters, the new micro heli that is giving these top toys national TV fame and fortune!

Tycoon is a new reality-based TV show starring multi-millionaire entrepreneur Peter Jones who made his name on Dragon’s Den. Based in Tycoon Tower on London’s South Bank, six budding businessmen and women will live and work together with the winning entrepreneur scooping the total profits made during the programme by all 6 companies. As well as being their mentor, Peter Jones will also judge each of the six entrepreneurs, and as we know he is not one to mince his words! He will be advising them and pushing them to make loads of money quickly, bringing down the axe on the companies he feels are lagging behind and not making the grade and leaving the remaining companies to battle it out on the final show which is subject to a public viewers vote.

One of the contestants on the show is Ian Morgan. He has an ambition to import new radio controlled micro helicopters into the UK, the first of these being Salvation helicopters.

With two counter-rotating blades, the Salvation 1 helicopter is very tiny, weighing in at a miniscule 20 grams! The 2 blades are manufactured from strong crash proof carbon fibre and make it very stable to fly using the 3-channel remote control that lets you steer the chopper up and down, left and right, forward and back. There is full trim control, which is unusual on micro helis such as Salvation helicopters. There is a rechargeable battery on board giving up to 15 minutes flying time between charges and each charge takes around 30 minutes to complete.

The Salvation helicopter is an excellent helicopter for the price; you can buy it for under £50! It is super lightweight and extremely

stable with full control from the 3 channel handset making it highly manouvreable. Unlike most indoor rc helicopters, the Salvation helicopter can be flown backwards. Having flown the Salvation helicopter for many hours I can recommend it. I for one hope that Ian Morgan wins the Tycoon show because the Salvation 1 micro helicopter is a top toy!

Texas Instruments Ti-83 Plus Calculator

2007-11-14T02:38:00.001-08:00

Calculators have shrunk in size and increased in price as consumers have sought out devices that do much more than simple arithmetic. Texas Instruments has their TI-83 Plus model which helps students with their Physics, Biology, Algebra, and Pre-Calculus classes. We'll examine why this model is so popular with today's classroom students.

Back in the 1970s, the slide rule gave way to calculators in many classrooms across the nation. Texas Instruments led the way as almost every student owned one of their models. Today, Texas Instruments [or, TI] continues to produce calculators and their TI-83 Plus calculator leads the way.
So, what sets this particular model apart from others? Well, it is pocket-sized, comes with 12MB of memory, does tons of math problems including statistical tests, has a complete alphabetical keyboard, and it can run programs to name a few. Still, if you are a Calculus student it doesn't do Calculus. However, you can bring the TI-83 Plus along for standardized tests and college admission exams.

The device runs with 4AAA batteries, so you need to make sure you are fully charged before you start your tests or at least carry spare batteries with you.

The TI-83 is not cheap as you will have to pay about $100. for a new one. Expect to pay a lot more if you purchase one through your university's bookstore; shop online to compare prices too.

The TI-89 may be a better option, especially if Calculus is in your future. Shop and compare and make sure that the model you want provides the calculations you need.

In all, the TI-83 carries on a long tradition of excellence for Texas Instruments. Sharp, Casio, and Canon are chief competitors to T.I., but judging by the TI-83 you will find what you need from the people of Texas Instruments.

Toshiba Qosmio G15-av501 Notebook Computer

2007-11-14T02:36:00.000-08:00

Purchasing a notebook computer can be a mind boggling experience with all the different makes and models out there. Toshiba has a strong entry in their Toshiba Qosmio G15-AV501 notebook computer. Let's examine why this particular model is certain to be an effective competitor.

Unlike most laptops the Qosmio takes computing to the next level. You can watch your favorite TV programs, play DVDs, or listen to music by way of its Windows XP Media Center Edition 2005 operating system. Sporting a 17" screen the Qosmio offers a nifty 1440 x 900 pixels resolution perfect for TV or video watching. Other key features of the Qosmio include:

* Intel Pentium M 745 Processor (Centrino), 1.8 GHz

* 512MB Memory

* Television Tuner

* Exceptionally Bright Screen

* DVD±RW/CD-RW Combination, 2 Hard Drives

* Wireless LAN Antenna

* Remote Controller

* Video Card

* NVIDIA GeForce FX Go 5700

* Weighs just under 10 lbs.

As much as the Qosmio is an effective performer, I have learned that the battery life is very short compared to models half its $2500. sticker price. That's right, $2500 [shop around, as prices vary]. So, only serious

multimedia experts will go for this machine and they will be keeping it constantly plugged in to boot! Any software you add will be extra, therefore expect to shell out well in excess of three grand if adding a productivity package, extended warranty, shipping, handling, taxes and the like.

Still, serious multimedia fans will find the Toshiba Qosmio to be a top performer in an ever expanding sea of laptop computers. For that reason alone it is worth a special look.

Oh, yeah, the 6255i can also be successfully used to talk with someone too! This is almost an afterthought when you consider its terrific features.

Because of its popularity, no less than twelve service providers have signed on to sell this 4.4 oz wonder. Therefore, your choices of carriers are excellent; shop around and compare the best plans.

I have seen the 6255i offered for as low as $49 after rebates when a two year plan is purchased. Not bad when you consider that the model retails for as much as $299 when purchased separately. You may be able to find an even better offer when shopping online.

Other leading Nokia flip top models worth a look include the 6170 featuring a camera, video, and voice capabilities; and the 7270 featuring GSM capabilities. In all, Nokia remains a formidable competitor in the ever growing cell phone marketplace and the 6255i is a strong entrant.

Surprisingly, Dell does include wireless capabilities in the form of a networking card.
HP Compaq nx9600 Notebook – HP’s acquisition of Compaq has produced a nice line up of notebook computers including this particular model geared toward those consumers replacing their desktop computer. Retailing at just over $1300 [before $100 rebate] this midrange offering is nicely loaded as it offers a 17" screen; Microsoft Windows XP Professional Edition; an Intel Pentium 4 Processor with Hyper-Threading Technology; a 40 GB hard drive; a 12 cell battery; wireless connectivity; and graphics oriented software.

Sony VAIO FS675P/H Notebookspacer – The Sony Vaio name is typically associated with high performing, high priced offerings. The VAIO® FS675P/H Notebookspacer fits the bill as this workhorse retails at just under $2000. Chief features of this model are: an Intel Pentium M Processor 750 (1.86 Ghz); Microsoft Windows XP Professional; DVD+R Double Layer/DVD+-RW; 1GB RAM; and a 100GB hard drive. The screen is 15.4" Widescreen5 LCD with XBRITE™ Technology and all of Sony’s top digital software for photography, video and audio are included as standard equipment.

All three models attract different types of consumers, but each model is a standout in its respective class. Consumers are the winner when it comes to shopping for a laptop as prices continue to drop, new features are added, and technology improves with every new model marketed.

Dell Inspiron 600m Notebook Computer

2007-11-14T02:32:00.000-08:00

After twelve years of owning desktop computers, I finally opted for a laptop so I would no longer be chained to my desk. After months of research and weighing various makes and models, I settled on the Dell Inspiron 600m Notebook Computer. This particular model has exceeded all of my expectations and at a price that is hundreds of dollars lower than many competing brands.

For several months I agonized over my next computer purchase. I knew I needed to be more mobile and only a notebook computer would permit me to take my "show on the road." Still, the decision making process was not easy as the number of different makes and models out there is mind boggling. Ultimately, I settled on a Dell in part because of previous good experience with the company as well as affordability of their product line.
The model I chose was the Inspiron 600m. As with almost everything that Dell builds, it is a "new" model; at least the 600m designation is. That is one of the confusing things about Dell and some other manufacturers: every month Dell introduces new models and you need a scorecard to compare one model with all the others. Fortunately, Dell's website allows you to do just that.

Key features of the Inspiron 600m include:

Lightweight: Just over five pounds.

Mobile Centrino Technology is standard.

14.1 inch screen

Pentium M 725 Processor

24X CD Burner/DVD Combo Drive

256MB DDR SDRAM 1 Dimm Memory

Wireless Network Card

Extended Battery

Microsoft Windows XP Home Addition

WordPerfect Productivity Pack

I kept my computer fairly basic but I did opt for the latest version of Norton Security, a surge protected cable, a wirless router, and a wireless mouse. I selected the wireless mouse as I thought the keyboard's mouse would be difficult to use. After two days I quit using the wireless mouse as I quickly got used to the built in one.

The screen is bright and the keyboard is solid. The mouse keys, however are noisy, almost clunky; you wonder if Dell could have used a quieter spring for each key.

The battery lasts at least four hours without recharging and when I do need to recharge I can go from nearly dead to fully charged in less than one hour.

For the price -- I paid just over $1100. for everything including shipping and local taxes -- the Dell cannot be beat. I haven't had to call customer service yet, so I cannot comment on that although in years past your call would be routed to a technician in India. This model comes with a standard one year limited warranty; I avoided a later sales pitch over the phone to get a three year warranty. Their top of the line warranty sends a technician to your house to fix your computer, so it can be option for those of you who do not want to ship -- and thereby lose the use of -- your computer back to Dell for repairs.

You will find the Inspiron 600m to be adequate for standard business work. Check out their myriad of other models if you do plenty of graphic design or if you need a larger screen. I am happy with the 14.1 screen, but you may prefer their 17" model.

Linsksys CIT310 Yahoo Phone

2007-11-13T01:24:00.001-08:00

Yahoo hasn’t made as large of an impact on the world of VoIP as Skype or Vonage has, but that doesn’t mean it did not try to leave its mark. Using the popular Yahoo! Messenger service one can get pretty simple VoIP service that is also pretty cheap. However, if you don’t have a phone that works with the system you are limited to a microphone and speakers or a headset in terms of actually talking on the phone using the service.

That is where the Linksys CIT310 Yahoo Phone comes into play. It is the only official phone on the market that is designed to work in sync with Yahoo’s internet phone service. And it works with it very well. Installation is pretty simple: it plugs in through a USB port and there are minimal amounts of software you will need to install in order to get the phone to work.

Once it is installed, the Linksys CIT310 phone connects directly with your Yahoo Messenger. You can, for example, see when your friends are online through the handset on the phone (it is cordless, of course), you can set your online status, check the weather and use the Yahoo! yellow pages functionality (meaning you can search for businesses in your area right from the handset).

Calls made over the Linksys CIT310 are crystal-clear, much higher quality than you would get from a headset using the Yahoo! phone services. Unfortunately this clarity somewhat depends on your Internet connection, you’ll definitely need a high quality high-speed internet set-up (DSL, Cable, etc.) in order to use the phone properly. You pretty much need to keep the Internet connection clear, though, no major downloading or anything else heavy on the network going on when you are using the phone.

The handset on the Linksys CIT310 Yahoo phone is pretty powerful in terms of range. The range goes up to 100 feet and offers the same crystal clear clarity all the way for those 100 feet. Walls and buildings can cut up the range a little bit, but for the most part this badboy will go just about anywhere you want to go; it is a lot more powerful than many normal cordless phones.

In fact, the Linksys CIT310 not only has compatibility with Yahoo Messenger phone services, it also works as a cordless phone all of its own. It is a dual-mode phone, meaning that it can work not only through Yahoo Messenger but also just by plugging it into your phoneline.

At about 80 dollars the phone is a little bit expensive, but it offers plenty of functionality for the price. Especially since the Yahoo phone system it works with it pretty cheap: you can get your own phone number through Yahoo Messenger for a minimal $3.00 a month, and long distance services are only $0.02 for anywhere in the US, cheaper to some countries (like Canada, only $0.01 a minute). It is a powerful system and very portable, if you want to use Yahoo phone services the Linksys CIT310 Yahoo phone is an excellent addition.

Microsoft Zune Review

2007-11-13T01:23:00.001-08:00

Microsoft would badly like to take away Apple’s title as king of the MP3 player world, and the Microsoft Zune is their attempt to take the crown for itself. This is their first foray into the world of MP3 players, and only time will tell if the Zune line of products will one day be able to one day take the top spot.

The Zune offers an impressive 30 GB hard drive, meaning you can fit a whole lot of media on there. It’s got a decent sized 3 inch screen, good for both pictures as well as video. The graphical UI is pretty simple and straight forward, as well as nice to look at, so there isn’t too much of a learning curve when you first pick up a Zune and start playing all sorts of music and videos, as well as looking at your pictures.

It definitely looks pretty stylish and comes in three colors: black, white and brown. Nothing too terribly fancy but definitely appealing to the eye. This is all done in a package that isn’t too large and isn’t too small, it’s a pretty nice fit, actually. It is a bit bigger than a similarly sized iPod, but oh well.

Like the iPod the Zune comes with its own online store: the Zune Marketplace. Here you can buy all the music that you want and put it into place on your handy dandy Microsoft Zune. It runs following a set-up similar to Napster and other online music stores, part of the problem is, though, that currently there are no movies for sale through the Zune Marketplace, you can only buy music.

Another problem with the Zune is the fact that it isn’t backwards compatible with Windows Media Audio (WMA). Basically it only works with WMA-DRM 9.1 and up files; if you’ve got WMA-DRM 9.0 or less, well, it isn’t going to work with the Microsoft Zune. Even a bigger slap in the face is the fact that it doesn’t WMV files for movies. Considering that this is the official video format for the Windows Media Player and other Microsoft products, this really doesn’t make any sense to me. Since WMV is known for being able to produce high quality video playback in a smaller size than, say, the MP4, this is a real let down.

One of the highlights of the Microsoft Zune is its wi-fi compatibility. This makes it very simple to share files between two Zune players. Of course, both people have to have the Zune in order to do this wi-fi sharing, which means you’ll have to hope you have friends who also use the Zune to share. The shared files also have limited playback; you can only play them every so often.

At $250 the Microsoft Zune isn’t too badly priced, and it is pretty easy to use. The biggest drawback is definitely its playback support; it only supports some files and there are a lot of major file formats that can’t be played, particularly when it comes to video files.

Sony Playstation 3 Review

2007-11-13T01:19:00.000-08:00

Ever since the launch of the original Sony Playstation all the way back in 1996 Sony has been a force to reckon with in the world of console games. The Playstation 2 only served to solidify its base as the premier gaming console out there. Now the Playstation 3 is the newest Playstation on the market.

The Sony Playstation 3 certainly has a lot to offer. It’s got a beautiful and slick design that makes it very attractive sitting there in your media center. It can both lie horizontally and stand up vertically, making it easier to fit in wherever you need it than ever. Just based on looks it is certainly a nice piece of technology.

Add to that excellent design plenty of functionality. It comes in two versions; one has a 30 GB hard drive and the other has a 60 GB hard drive, more than you are going to get on many notebook computers. That’s a lot of storage punch and definitely one of the highlights of the Sony Playstation 3.

Just as the Sony Playstation 2 was backwards compatible with Playstation One games, so is the Playstation 3 backwards compatible with both Playstation 2 and Playstation One games. This is really nice, no having to get rid of all your old games because they won’t work with your new console: they work perfectly with your console, no problem whatsoever.

Sony is of course behind the new Blu Ray technology which is hoping to win as the next generation of digital video technology (its main competitor is the HD-DVD), and the Sony Playstation 3 can play Blu Ray disks. Don’t worry, though, it is also backwards compatible with old school DVDs. In fact, hoping to boost sales of the new PS3 Sony is offering 5 free Blu Ray movies with the purchase of a Sony Playstation 3 these days.

The Sony Playstation 3 boasts unbelievable graphics, it also boasts excellent online play through the Playstation Network that is also 100% free. That means you can play games with other players with absolutely no cost, unlike some other major consoles out there. The online system is also built into the console; no need for any additional components.

There are a couple of problems with the system. For one thing, the controller doesn’t have any rumble capability (something which has been around since the PSOne). This problem will most likely be fixed, but it is somewhat of an annoyance if you are used to the rumble functionality. It uses BlueTooth technology for the remote, which is good, but it has no infrared port on the device, meaning that you can’t use a traditional universal remote for DVD watching; it has to be BlueTooth. These are a bit more expensive and this is a drawback for the PS3.

The biggest single drawback to the Sony Playstation 3 is definitely the price. It is the most expensive console by far on the market, and the games available on it still don’t set it apart from the pack compared to, say, the X-Box 360 or the Nintendo Wii. However the underlying technology is incredibly powerful and sophisticated, so there is definitely room for the games available to improve.

Marine Electronics

2007-11-12T02:53:00.002-08:00

Autopilots The first self-steering gear was introduced in the 1920's to control model yachts but it was not until 1948 that the principle was applied to full scale yachts. Standing at the helm for lengthy periods, monitoring instruments and keeping a good look out can be very tiring. An autopilot relieves the helmsman from steering the correct course leaving him free to maintain a proper watch. The autopilot can be set to either steer a compass course or a course relative to the wind. A fluxgate compass or electronic wind indicator feeds information to a microprocessor which then makes the necessary rudder movements to return the vessel to it's required course. The mechanical power is applied to the rudder by either electric linear activators, hydraulic pumps or rotary drives. GPS/Chart plotters can be used to input navigational instructions to the autopilot.

Battery Chargers will keep batteries fully charged thereby extending their working life.

Chart Plotters Typically a chart plotter consists of an antenna, mounted high on the boat, to track GPS signals and a display unit sited either at the at the navigation station or the helm of the vessel. The vessels position is sent from the antenna to the display unit which in turn shows it graphically on the chart. The Chart itself will look similar to it's paper equivalent and show depth, land mass, navigational aids such as bouys and potential dangers in the form of wrecks and obstructions. The user can add way points to the chart and zoom in and out of the display. Chart plotters can be connected to drive an autopilot and/or send GPS data to a fish finder or radar. They can also interface with a laptop enabling complex passage planning to be done away from the boat and then entered into the chart plotter after arriving at the boat.

Magnetic Transmitting Compasses work like traditional compasses using magnets to determine the vessels orientation to the earth's magnetic field they then transmit the boats heading to an electronic display. They make steering easier than with conventional compasses because they display steadier headings and do not suffer from the "lag" that occurs when making a turn. They can interface with chart plotters, autopilots and radar. Fluxgate Compasses consist of two pieces of readily saturated magnetic material with coils wound round them in opposing directions. AC current is passed through the coils and the material is saturated in one direction and then the other. The earth's magnetic field affects slightly the time at which saturation occurs, earlier in one coil and later in the other. The difference is then calculated giving an output proportional to the earth's magnetic field. They are accurate to 0.1 of a degree. Their output can be displayed digitally to the helmsman or they can interface with autopilots, chart plotters and radar.

Echo Sounders work on the same principle as sonar. A transducer emits a narrow beam of high frequency sound. This is reflected by any solid objects and the time between transmission and receipt of the echo is measured. The speed of sound through water is know and so the range or distance to the sea bed can be calculated. That is then displayed in metres. Forward Looking Sonar (FLS) enables you to see the underwater hazards before you're actually on top of them. A typical range for a FLS is 150 metres.

An Emergency Position Indicating Radio Beacon (EPIRB) is a piece of equipment designed to float free of a vessel in distress. It then sends a radio signal that can be detected by Search and Rescue Satellite Aided Tracking (SARSAT) satellites. They relay a message to a ground station that in turn can instigate a search and rescue operation.

Fish Finders use the same technology as sonar. A narrow beam of high frequency sound is transmitted by a transducer, this is reflected by solid objects such as the sea bed. By developing this technology fishfinders provide displays that show where the fish are and they can differentiate between bait fish and larger species

Global Positioning System (GPS Receivers) - This system was originally designed for military purposes and is owned and operated by the United States Department of Defence. 24 satellites are arranged in a "birdcage" around the globe, they are positioned in such a way that at any place on the earth's surface a direct line of sight can be established to a minimum of 4 satellites. A fix is obtained by measuring accurately the distance between a satellite and the GPS receiver at a precise time. Because the exact position of the satellite is known, these distances provide position lines which are converted by a microprocessor within the GPS receiver to read outs of latitude and longitude.

The log is used to measure the boats speed through the water. A paddle wheel or impeller, mounted below the waterline is turned by the flow of water, this generates electrical impulses that are fed to a microprocessor that displays both speed and distance run.

Inverters - On most boats today you will find domestic equipment of one sort or another. For on board entertainment there are televisions and stereo systems. With the popularity of chart plotters comes the PC or laptop. Maintenance often requires the use of power tools. Liveaboards might have a washing machine, dishwasher or microwave. Can take 12v, 24v or 48v supply and convert it to a stable 110 v or 220v AC supply.

Navtex can perhaps best be described as a continuously updated telex service providing navigation and weather information within specified areas. An on board receiver, tuned to 518kHz, the worldwide Navtex frequency, if left turned on will either print out or display the latest massages sent from a local station. The service is available up to 400 miles from the coast.

Radar enables you to see what otherwise would be invisible. They offer greatest benefit at night and in fog or rain and are of particular value when close to shore or in busy shipping lanes. They consist of an antenna and a display. The antenna sends out a stream of RF energy which is reflected back off hard objects. When this energy is bounced back it is converted to a signal which displayed to the user. The antenna rotates every few seconds, the display continuously calculates the direction of the antenna and so a precise bearing to the target is calculated. The time is measured for the energy to be reflected and so the distance of the target is also displayed.

Satellite Phones consist of an antenna, a modem and a normal handset. They are powered by an iridium battery. Their range is anywhere covered by in Inmarsat Mini-M satellite. Voice, fax, email and data can be transmitted.

Satellite TV requires an antenna and of course a television. Reception is available within a "footprint" which is based on EIRP (Effective Isotropic Radiated Power) of a transmitting satellite. The EUTELSAT together with the two ASTRA satellites cover Europe. NILESAT and the two ARABSATs cover Africa and the Middle East. Good coverage is also available in North, Central and Southern America.

SSB Radio has a range of several thousand miles. You will need an FFC license, or the equivalent in whichever country you plan to operate it. Power consumption is a consideration. Up to 100 Watts may be required for transmission. SSB radio requires several items of equipment. A transceiver capable of SSB operation, An antenna, this must be 8 metres long and in practice most boats use a backstay or shroud for the purpose having fitted the necessary insulators. An antenna tuner matched to the transceiver model. If you want to send email you will also need and radio modem and computer.

VHF Radio The power required to transmit is minimal, all sets have the option of transmitting on either 1 Watt or 25 Watts and the lower power should be used whenever possible. Unlike telephones that allow you to both talk and hear at the same time most VHF sets require you to press a transmit button prior to talking. This is known as simplex. Duplex sets are available but are much more expensive. VHF radio waves travel in straight lines so the aerial should be mounted as high as possible, preferably at the masthead.

Why Has The Nintendo Wii Become So Popular In Japan

2007-11-12T02:53:00.001-08:00

Two weeks after it was released in the US late last year, the Nintendo Wii came out in Japan, and consoles literally flew off the shelves. Reports received from areas such as Akihabara (the major electronics district of Tokyo) and Shinjuku (another massive shopping location) said that it was nearly impossible to walk down the sidewalk anywhere near an electronics store.

Without doubt, the most popular choice of games console by the Japanese people is the Nintendo Wii, although the PlayStation 3 and Xbox 360 have sold quite well in Japan. You couldn't escape the ads for Wii anywhere last year, and it seemed to be all Japanese video gamers were talking about. So, why is the Nintendo Wii, loved so much in Japan?

To start with, the Nintendo's have always outsold the other gaming systems in Japan. A survey noted that the Nintendo games tend to contain subject matter that was interesting to Japanese gamers. They said that the Nintendo games appeal to all ages and tastes.

The interactive features of the Nintendo Wii have become extremely popular. The Nintendo Wii makes use of a new remote sensing technology, which means that while playing a game, such as golf you can actually take a swing to hit the ball. Naturally, this technology has caught on with the non-gamers as well as gamers. Recent studies have discovered that more woman and older adults, demographic groups that don't normally go for games consoles in a big way, get a big kick out of the Wii's interactive features.

There was tons of promotion and advertising. It was almost impossible to get anywhere near an electronics store in Japan at the end of last year without noticing a guy dressed up like a giant remote controller, or kids of all ages crammed around a Wii demo console. The Wii was witnessed just about everywhere last year, much more so than any of the other consoles. With such a big push off, it had to be popular.

One of the main strengths of the Wii console is it sports games. Lately, sports games have become more and more popular in Japan, and they have started to outsell the more traditionally popular adventure games such as Legend of Zelda. The Wii offers great quality, realistic golf, baseball and tennis, among others. For the Japanese gamers, these are a great step forward from the sports games of yesterday.

Then again, maybe the massive popularity of the Wii in Japan is due to those wacky pictures in its safety manual. The Wii has been stirring up headlines worldwide mainly because of the Wii strap related incidents, and the Japanese safety manual covers everything. It's packed with comically rendered pictures of housewives whacking their husbands around the head with controllers, Wii-motes stuck halfway down a child's throats, and people injuring themselves in a variety of outlandish ways. Do a quick internet search yourself and see if you can find some pictures!

While the Nintendo Wii is undoubtedly the most popular new gaming system in Japan, the PlayStation 3 does come in as a close second. Some sources on the web believe that the PS3 does actually sell better, but it's hard to say for sure. Certainly, the new interactive features are a draw for Japanese people, who are always searching for something new to enhance their gaming experience.

Information Awareness and Electronic Civilization Grid Defense System

2007-11-10T04:04:00.002-08:00

Most people do not want the government intruding in their lives. They do not wish to have the government listening to their phone calls, knowing their locations or watching their every move. Sure that makes sense but that is not actually how it works. No one has time to watch you pick-up your kid's from Karate Practice. Rather it is a safety system, a net if you will and if something goes down. If your child is abducted or Al Qaeda Terrorists try to pull some shenanigans then you will be very glad to see this is in place.

It is a lot like Zone Defense in basketball, law enforcement or outlining threat assessment in the modern net-centric battlespace. The question is; Do you want to Win or are you willing to accept a "Sneak Attack" because even if an attack only gets a few thousand people in the United States, if we attack back it saves the world millions of lives on a second reciprocal response. And it saves us on the political or mass media fall-out from a pre-emption. So with a system in place you can cut out the cancer, before it gets growing. You see?

Those who condemn such have other thoughts on grounds of liberty, constitutionality and such they need to recall some recent Supreme Court cases and the right to privacy again? The government won the last case, it is all legal and you are not granted the right to security of data from a third party.

You use an internet provider, ISP, company to rent a car, fly a plane, credit card, etc? That information is not guaranteed protected? You want to take a magazine or fill out a form? Once you do all bets are off says the Supreme Court. So, if someone really has a problem with that, they need to take it up there. A case like that would cost 500,000 K minimum to hear and you might not like the results you hear when you are through or someone once said.

I certainly hope this article is of interest and that is has propelled thought. The goal is simple, to help you in your quest to be the best in 2007. I thank you for reading my many articles on diverse subjects, which interest you.

Teens: Life v. Electronics

2007-11-10T04:04:00.001-08:00

Teens today have so much more to distract them besides their homework, the opposite sex, friends, family members, and extracurricular activities. Besides learning how to drive, teenagers are occupied with playing with an assortment of electronic gizmos including cell phones, camera phones, personal computers, MP3 players, DVD players, ipods, xboxs, digital cameras, the list goes on. Wired? You betcha…and then some. Perhaps all of this electronic gadgetry has you concerned and you are wondering just how you can extract your teen and involve them in an outside activity where they can expand their minds and refresh their bodies. Are you out of ideas? Let’s look at some options that may appeal to them and remove the worry from you.

Work on the Car So, you think that a car isn’t a kid magnet as much as when you first learned how to drive? Think again. Today, kids are pimping their rides and expressing themselves through their cars. Custom paint, decals, blacked out windows, even faux aircraft wings are being attached to the outside of their cars. On the inside, it can be totally surreal: rear view mirrors wrapped with a studded belts, frilly seat cover trim, pushpin art attached to the headliner, decals everywhere, etc. Let them pimp your Camry or Explorer…that’ll keep them off the computer…and get you noticed too!

Volunteer Help your teen organize a group of his or her friends to clean up the neighborhood, paint an elderly neighbor’s house, teach younger kids how to ride bikes, or visit folks at the local nursing home. You remember when you were a teen and you heard the comments from your parent’s generation about kids not wanting to do anything or being “no good,” right? With a little direction, young people can do just about anything and are more than willing to help out if you believe in them. Rewards are nice too…be prepared to throw a pizza party after their time of service is over for the day.

Get a Job Kids who hold a job while going to school learn how to handle their money and budget their time. Limit work hours to fewer than 20 per week to ensure that their grades are not adversely affected. If your student is involved in extracurricular activities too, make sure that this time is included with the hours that they work. Maintaining good grades is essential, no job or outside activity is worth it if it takes away from their schooling.

In all cases, show your teen that you believe in him or her. As you know, parenting is much more than providing for their needs…you want to guide your child from youth toward adulthood by showing them that there is much more to life than all things electronic. So, gently disconnect your teen and get them involved with other pursuits.

US Military Electronic Attack Robust Systems for Warfare

2007-11-10T04:03:00.001-08:00

When the United States Military plans an air-strike it plays tough and Electronic Attack is something that the United States is best at, as they come to win and set up the modern net-centric battle space. Anyone who is foolish enough to doubt the ominous ability of the greatest strategists in the world to get the job done, is so caught up in their own rhetoric that they will fall harder and have their optimistic exuberance crushed to the ground and thus their will to fight will turn to a short-term bewilderment until their last breath and the heat of a 1000 Suns during that split second of evaporation.

For over a week now I have been trying to re-write that sentence and I just can't, it must stand the way it is because that is the truth. Indeed that sentence is part of a book I am writing now? Maybe a few modifications, but essentially well, that's it really?

When people talk about the anti-aircraft weapons that Iran has, which they were sold by the Russians and Chinese, one must also consider that those are not of the same modern up to date generations of weapons technologies of the US Military. Actually they are not even close. As Iran continues to build nuclear weapons which will most likely end up in the hands of International Terrorists, the World must do something.

Even as the Iranian President threatens to blow Israel off the map, it is widely thought that Iran is un-defendable and currently surrounded. In fact its only main ally, Syria is a few minutes flight from Israel, ain't no one coming to their aid. We should be concerned with nuclear weapons in such nation-states and even more so in the hands of international terrorists too.

I certainly hope this article is of interest and that is has propelled thought. The goal is simple; to help you in your quest to be the best in 2007. I thank you for reading my many articles on diverse subjects, which interest you.

Setting up a Surround Sound Audio System For Your Car

2007-11-07T03:00:00.000-08:00

For decades now, car people have always pushed their car stereos to the limit in order to produce the best sound possible. Our grandparents’ cars with their bulky and static-filled AM radios gave way to the FM broadcasts and cassette tape playing stereo’s of our parents. Now, car manufacturers are going digital with the use of not only CD players but satellite radio with MP3 playing compatibility.

The latest and hottest growing trend in car audio now is the idea of surround sound speaker systems. The thought behind it is to have all the speakers in your car set up exactly like that surround sound audio system you have in your living room. There is a reason why everyone wants one in their car. It simply sounds incredible. Here is how you can go about bringing that movie theater sound experience into your daily ride to work.

* One of the first goals to check off your list is find a stereo head unit which allows you to wire in a surround-sound processor. Since the processor will be digital, your head unit needs to supply a digital signal. You will also need fiber-optic cables. They are used to transmit digital signals between the components. If you previously purchased a nice head unit but it cannot supply digital signals, get a CD changer with fiber-optic connection. Connect the processor to the CD changer but remember that unit you will not get a surround-sound effect, if you play a CD. You can always select a surround-sound processor that converts RCA signals to digital.

* Make sure your car is equipped with a high-end CD changer and/or DVD unit that plays the software that carries the surround-sound signals.

* You should install a five-channel amplifier that can provide power for the front speakers, the rear speakers, and the subwoofers. Each corner of the car plus the subwoofers will be separate channels.

* The center channel should have a 4- to 6-inch midrange speaker and a tweeter. This type of combination should be in its own enclosure and placed in the center portion of the car’s dashboard.

* You now need to install an amplifier to run the center-channel speakers. You can get away with a two-channel amplifier played bridged mono but have it contain an electronic crossover which can be outboard, or built in to the amplifiers.

* You are now set to begin installing the speakers which will be in all four corners of the car. Some of the newer cars already have speaker locations work perfectly surround-sound setting. Older cars are a different story and will require a touch of imagination and some work. You’ll need to add a tweeter high on the pillar at shoulder height, while a midrange speaker is used in the factory-made opening in the door.

* Now that all of your speakers are in place, set the electronic crossover for the center channel. Don't play it at full range but opt instead for about 80 Hz and up for optimal sound quality.

* Once everything has been installed, adjust the system to find the perfect fit of sound quality and volume for you. Play around with the amplifier gains and then the surround sound processor for any type of tweaks you may need.

Home Electronics - How to Find Hot Deals

2007-11-06T03:50:00.000-08:00

On wish lists around the country, home electronics have bypassed traditional favorites like clothes, lingerie, and jewelry as the most coveted items. But whether you're buying home electronics for yourself and your family, or as a gift, the burning question is always: Where do I find hot deals?

After all, why pay premium prices for LCD flat screen TVs, an iPod, a digital camera, or a cell phone when you can get hot deals at a fraction of the cost? While it's true that the prices for all home electronics are trending downward, it pays to shop around for the best possible prices before you make a purchase.

LCD Flat Screen TVs: Although LCD flat screen TVs for home entertainment systems are massive and relatively expensive, portable LCD flat screen TVs are ultimately affordable - especially when you can find hot deals and discount prices. For example, a seven-inch LCD flat screen TV with a full channel VHF/UHF receiver, built-in speakers, 1440 x 234 resolution and an active matrix display, a detachable and mountable stand, and A/V input jacks might list for $249.99. You can, however, find it for $144.29, a savings of over 42 percent.

iPod: Every family needs at least one iPod, and although the iPod Shuffle lists for $179.99, there are places where you can get hot deals and purchase an iPod shuffle for $109.43, or a discount of 39 percent. Likewise, you can save over 27 percent on an iPod Nano, and pay only $289.77. If you're willing to buy a refurbished model, you can get it even cheaper.

Digital Camera: Let's face it: film cameras are so twentieth century. There's no need to bother with bulky camera equipment and film and developing costs when you can snap all the pictures you want with a digital camera. And, there's truly a digital camera for every budget, with prices ranging from $100 to $10,000 and more. But when you look for hot deals, you can get a lot more camera for your money. If your budget is $150, for example, you can probably find a digital camera that retails for $299, but that is discounted almost 50 percent. Again, if you are willing to buy a refurbished digital camera, the savings can be even greater.

Cell Phone: Everyone in the family needs a cell phone, so it only makes sense to look for hot deals on cell phones. If you buy every family member the same cell phone (or the same cell phone in a variety of colors), you can usually find a calling plan that is extremely cost effective.

There's no question that hot deals on home electronics - and even electronics that double as a car accessory - are out there. Your best bet is to look for an online discount source. Because online stores don't have to pay the overhead that brick-and-mortar stores have to pay, they usually offer lower prices. Online stores also move a lot of inventory, so their hot deals usually surpass those of even the electronics megastores. Always comparison shop, but remember that for the best hot deals, let your mouse do the clicking.

Buying Refurbished Electronics - Is it Worth the Risk?

2007-11-05T04:10:00.001-08:00

Introduction:

We are always looking for new ways to save on the bigger purchase - irrespective of whether this is a new PC or notebook, a digital camera, or a big screen LCD HDTV for the living-room entertainment area. Seasonal and clearance sales are always on the agenda of bargain hunters, but there is a further option - that of buying refurnished products. For example, a refurbished LCD TV may sell online for anything from 50% to 70% of its retail price.

Still, even at these big savings, it is not easy to get someone to buy a refurbished product for the first time. To the uninformed, buying a refurbished product may seem like a compromise; it is as if buying a car with dents and scratches on the paintwork, or unknown problems with the mechanics. However, in the electronics world, things are somewhat different. It is unfortunate that to many, it is not so obvious what the tag 'refurbished electronics' does actually mean.

Refurbished electronics can be either third-part refurbs or manufacturer (factory) refurbs. Third-party refurbs offer greater savings and do come with a warranty but it is only factory refurbished electronics that come with a manufacturer warranty. For the smart shopper, buying factory refurbished electronics is a way to enjoy substantial discounts and still have a product that is essentially 'like new', but...

You need to exercise constant vigilance when buying refurbished electronics.

This is only possible if you have a thorough understanding of what the 'refurbished' tag, once assigned to a product, implies in the electronics world.

What 'refurbished' products are not?

Before we delve further into what may qualify as refurbished electronics, it is important to get a clear understanding of what cannot be labeled as 'refurbished'. In particular, there is the misconception that 'refurbished' and reconditioned' are the same.

A refurbished product may or may not have been installed, repaired, or slightly used for reasons given further on in this article. On the other hand, a reconditioned item is a used product, that may have been used for an extended period by a first owner - often under lease - but then was repaired (not necessarily by the manufacturer), and resold by a retailer.

'Used' re-conditioned products represent greater savings over refurb units as these sell cheaper, but then such products constitute a higher risk. This risk is even more pronounced when dealing with expensive electronic products such as rear projection TVs, home theater projectors, flat-panel HDTV sets and the like. You can never really tell what has been the impact on the aging of the respective electronic components inside the unit as a result of the previous use.

We say: Be wary of such products. Instead, if you are after a smart buy and a great bargain, opt only for 'factory certified' refurbished products. These still represent substantial savings over the normal retail price, and carry a manufacturer's warranty.

So... what qualifies as 'Refurbished Electronics'?

In general, refurbished electronics are items that were returned for one reason or another, to the manufacturer. These items are then re-tested at the factory to make sure they are in tip-top shape. Any defective or damaged parts - if need be - will be replaced in order to restore the product to its original specification, and then the product is repackaged 'like new'.

Consumer laws prevent manufacturers from selling anything considered factory refurbished electronics as 'new' since the original factory seal has been broken; hence these items are sold as 'refurbished products' often at deeply discounted prices.

More specifically, reasons for returns include:

Customer Return: Most major retailers offer a 30-day money back guarantee; during this period, a customer may return the product for whatever reason and still get full refund. If there is nothing wrong with the product, most stores will simple reduce the price and resell it as an 'open box' special. However, if there is some sort of defect, the product is returned to the manufacturer were it is inspected and/or repaired, and then repackaged for sale as a refurbished item.

Shipping and Exterior Damage: These include damaged packaging due to mishandling, the elements, etc., in which case the product itself may be perfectly fine. These may also include minor damage to the product exterior casing, such as dents, scratches, etc., and any other exterior damage that in it self would not affect the product performance. Retailers would normally return these products to the manufacturer. The manufacturer would then inspect the product, replace any damaged casing, etc., and then repackage the item just like new. However, these items cannot be sold as new; hence they are tagged as refurbished electronics.

Demonstration Units: Sometimes demonstration units at major retail stores, trade shows, and even returned items by product reviewers, are often returned to the manufacturer where they are inspected and/or repaired if needed, and repackaged as refurbished units.

Opened Box: Sometimes, if a box was simply opened, the item is returned to the manufacturer where it is re-tested and repackaged. Even though technically, there is no issue here, yet the item cannot be classified as new; instead, it will have to be sold as refurbished electronics.

Defect during Production: If a specific component is identified as defective once the product leaves the factory - say as a result of an abnormal number of customer returns during the warranty period, a manufacturer may recall a product from a specific batch or production run that exhibits the same defect. When this occurs, the manufacturer can repair all the defective units and send them back out to retailers for sale as refurbished units.

Overstock Items: While most retailers with an overstock of a particular item would simply reduce the price and put the item on sale for clearance, yet there are instances when a manufacturer wants to introduce a new model on the market at a time when there are still a substantial number of older models on stores shelves. In these circumstances, the manufacturer may opt to collect any remaining stock of the older model and redistribute them to specific refurb retailers for quick clearance. Overstock items are brand new items; these can be sold either as a 'special promos' for quick clearance, or can be labeled as refurbished electronics and sold at deep discounts.

To strike the best deal, you have to act fast, but not too fast!

Fast... because when it comes to refurbished electronics, you cannot expect to simply walk into a store and pick up your favorite refurbished LCD TV or plasma unit off the shelf. Major refurb retailers like Second Act, work with manufacturers and distributors to acquire as many products as possible, yet the quantity they acquire can vary from just a few units to a couple of hundred units. In other words, you never really know how long they will last, and at the big savings associated with refurbished products, inventory levels change all the time. Additionally, you never really know if a particular model will be available as refurbished item.

But... do not just jump on the first deal. Act too quick and you may equally miss on the right deal. Act only when you feel you have got the right product at the right price. Once you think you have found what you want, then it is time to check with the retailer about return policies and warranty issues. If the refurbish item is factory-refurbished and comes with a full manufacturer warranty, then it is time to act!

Finally, remember: Purchasing a refurbished item can be a great way to a smart buy. There is no reason why the 'refurbished' tag should lead to a negative connotation to the product under consideration. At the same time, it is important that you inspect the product yourself within the return policy period. This is especially important since with refurbished electronics, you are getting a bit of a hit on product warranty in that you are only getting a typical 90 days warranty against the one year or so associated with standard products.

Happy bargain hunting!

This article is an excerpt from a detailed informative guide appearing on Practical-Home-Theater-Guide.COM, and that discusses at greater length the issue of 'Buying Refurbished Electronics'. It provides additional tips and advice that should help you transform the risk into a great buy - one that results in a big reduction in price. This additional information should also prove useful especially when buying online.

Home Electronics: The Facts About Plasma TV

2007-11-05T04:07:00.000-08:00

Not so many years ago, homes across the country watched their favorite TV shows on a bulky floor model that took awhile to warm up before you could see the picture, didn’t offer anything in the way of remote control manipulation and offered a washed out image on the TV’s cathode ray tube hosted screen...and folks were thrilled to have such marvelous technology in their midst. Today, all of that’s been changed, with the introduction of plasma TV.

Instead of trekking to the local theater to catch a favorite flick, those who own a plasma TV can get pretty much the same experience in their own homes. If the thought of shelling out the amount of money that one of these sets costs makes you flinch, think of how much you’d be spending to buy movie tickets, and your perspective will change. If you multiply the number of movies that you’ll watch on your plasma set by $8.00 (the average price of a movie ticket these days), you’ll see that the set will quickly pay for itself. Even if your purchase price was $4300 for a 50” widescreen model, you’d see a profit after just about 538 movies were viewed – watching two movies per day, then, would have you realizing a profit after about 9 months. When you factor in the cost of popcorn and a drink, you’ll be seeing a profit a lot quicker than that.

Known for their magnificent color, clarity and brightness, plasma TVs come in a variety of sizes – from 37” to over 60”. Instead of the bulky floor models of yesterday, the plasma TVs of today are as thin as 3.25” – demanding far less accommodation for depth – and can be mounted on the wall. This helps to provide a true theater experience without the need for a lot of bulky hardware cluttering up the room.

Before you run out to make a purchase, there are some things that you’ll need to consider in order to make the best decision regarding a new unit for your home. Take a good look at the size and layout of the room that will house the plasma TV. If the room isn’t overly large – or if you have an apartment dwelling – then a 42” screen should do the trick. For larger rooms, upper range screen sizes (in excess of 60”) would probably work best.

Pricing is determined by the size of the unit, as well as the manufacturer. If, for instance, you purchase a model from Pioneer, Sony or Panasonic, you can expect to see a higher price tag. On the other hand, the quality of these units exceeds that of their competitors, so it’s all relevant. Ranked among the best of the plasma TVs is the Sony 42XBR, offering outstanding visuals and state-of-the-art operating tools.

You’ll probably find lower prices when shopping on the internet, but be sure to look for the Better Business Bureau seal on the website – which is represented by a BBB linked logo – or you can’t be sure that it’s not going to be a fraudulent (or, at least, substandard) transaction.

What About batteries around of us

2007-11-03T00:30:00.000-07:00

Batteries are all over the place -- in our cars, our PCs, laptops, portable MP3 players and cell phones. A battery is essentially a can full of chemicals that produce electrons. Chemical reactions that produce electrons are called electrochemical reactions. In this article, you'll learn all about batteries -- from the basic concept at work to the actual chemistry going on inside a battery to what the future holds for batteries and possible power sources that could replace them!

Rechargeable batteries undergo self-discharging when left unused. Always store a battery pack in a fully charged staged for storage.
Exercise the Battery - Do not leave the battery dormant for long periods of time. We recommend using the battery at least once every two to three weeks. If a Laptop Battery has not been used for a long period of time, perform the new battery break in procedure described above.
Many lithium ion packs have a built-in meter consisting of a row of LEDs and a button. To accurately report the state of charge, the pack electronics has to keep a record of the current in and out of the cell, as well as a model of its behaviour. This can become more inaccurate over time; more modern cells will recalibrate themselves.

However, batteries are not quite that linear. For one thing, all batteries have a maximum current they can produce -- a 500 milliamp-hour battery cannot produce 30,000 milliamps for 1 second, because there is no way for the battery's chemical reactions to happen that quickly. And at higher current levels, batteries can produce a lot of heat, which wastes some of their power. Also, many battery chemistries have longer or shorter than expected lives at very low current levels. But milliamp-hour ratings are somewhat linear over a normal range of use. Using the amp-hour rating, you can roughly estimate how long the battery will last under a given load.

Advantages of Wi-Fi camera

2007-11-02T00:10:00.000-07:00

Planning to buy a new digital camera? There are so many cameras in the market with so many different features. It is not always easy to decide what are the features really needed. I would say Wi-Fi connection is one of the important features that your new digital camera should have.

In traditional Digital cameras we are using USB cables to connect with computer or printer. But in Wi-Fi enabled cameras you can connect them with out any physical connection. While sitting at the airport, take photos and mail them to your friend or save them to your online album. Regardless how much storage left in the camera, you can keep on taking photos and save them in your album. If having party at home, keep on shooting and transfer the photos directly to your computer or send them to your printer for printing. Also you can view photos that are stored in your online album.

To connect your camera with computer, both your camera and Computer should be connected to wireless network. Ideally you can setup your home wireless network. When your Wi-Fi camera is within the reach of your home wireless network, it can be connected with the network using its Wi-Fi card. In similar way your computer also can be connected with the wireless network using the PCI card in it. So, when both camera and computer are connected with the wireless network, they can talk to each other wirelessly and ready to transfer photos from camera to Computer.

If you want to print photos, connection needed is almost same as it is with your Computer. In this case your printer should be connected wirelessly. To do so, either you should have printer which having in-build wireless adapter or else you can use an external wireless USB adapter for your printer, That will help to connect your printer with wireless router. And you can send your photos to printer from your camera which is already connected with the wireless router.

Another advantage of having wireless connection is you can directly mail photos or send photos to your online album. Here also camera should be in the range of some wireless Internet connection. That can be wireless connection in public place like airport or some coffee shop, or that can be Internet connection available from your Home wireless network.

Again when your camera is connected to Internet by Wi-Fi, you can view photos from your online photo album.

So, I guess now you will agree that Wi-Fi connection should be one of the major criteria when you are planning to buy your next digital camera.

2007-11-02T00:09:00.000-07:00

The idea of a having a portable audio player dates back many years ago, when the option then was a fairly big cassette-tape-playing two-speaker audio system. Eventually these devices got smaller and back in the late seventies a hand size cassette-tape audio player was made available. Now as electronics evolved and with the mp3 audio format, one can satisfy his needs for a portable audio device thru the use of mp3 players.

Mp3 players became very popular and it is very common to see people using it while doing many activities such as jogging, commuting to work, traveling, buying groceries, computer related tasks and others.

For those who intend to purchase an mp3 player, one might consider the following tips:

1 - The internal memory size of an mp3 player will determine the amount of mp3 songs the device will be able to hold. Some models may even have an internal hard drive to store songs, however the size and price may go up a little bit and it is not recommend to be used by someone doing intensive physical activities. Also some models may the have the option of flash memory.

2 - The battery life is a very important feature, because it will determine how many hours the mp3 player will function properly. Make sure the mp3 player comes with an AC/DV adapter for quick battery charge.

3 - There a lots of sizes of mp3 players. Features such as a larger screen, video capability, hard drive and others, all add up to a bigger size. And price too!

Understanding Electric Motors

2007-10-31T00:38:00.000-07:00

The world of electric motors is quite fascinating. For many making and collecting various types of electric motors is a hobby and for others making the best electric motors to power various devices is a profession. Whatever the approach is, but electric motors offer innumerable possibilities for improvisation. Working with electric motors and understanding them is a rewarding and learning experience. Let us find out more about electric motors in general. Usually, electric motors can be classified into two main types. They are direct current or DC and alternating current or AC motors. DC or AC is very common terms and they refer to how the electrical current is transferred through and from the motor. Both types of motors have different utilities and uses.

DC motors are usually available in two general types. Alike that, AC motors also come in two different types. They can be two phase or three phase AC motors. Although on technical front, the differences in DC and AC motors are sometimes marginal, but some of these differences make one types better than the other for a certain use. In general, the DC electric motors work for conditions controlling the speed is essential. It is due to the factor that DC motors have a steady and constant current. DC motors are also the first and earliest motors used. But these good factors are also accompanied with some limitations; for instance, the DC electric motors are incapable of producing power over long period of time. Most of the electric companies are aware of the limitation of the DC motor and have found that the power was lost as the electric current was transmitted. One of the variant, the Brush DC motors, use certain rings that conduct the current and form the magnetic drive that runs the rotor. On the other hand, the brush-less DC electric motors bring forth a switch to generate the magnetic drive that powers the rotor. Direct current motors commonly used in most of the electric appliances in your home.

Now coming back to the AC motors we find that these kinds of motors are commonly used on the basis of their type. For instance, the single phase AC motors are used for general purpose. This type of motors will work efficiently in different conditions. AC motors are effective for systems that are hard to start because they need a lot of power for this purpose. The three phase AC motors, also called polyphase, are commonly found in industrial sector. The AC motors have a high starting power built to transmit lower levels of overall power. As it alternated the power, so it gets its name AC. The amount of power specified by an AC motor is determined by the amount of power needed to operate the system.

Generally, the DC and AC electric motors are easily come across everywhere from the home to the car to industrial uses. The introduction of DC motors is still considered no less than a revolution and when AC motors were available in the market the way motors were looked at changed because of their amazing starting power potential. DC motors and AC motors are different in many ways, but they still both are used to power the world of electric appliances.

Your Guide to Hidden Cameras and Other Security Cameras

2007-10-31T00:14:00.000-07:00

With Father's Day just around the corner, it's time once again to figure out what I'm going to get my dad. Like many men, he's an electronics enthusiast through and through. He's what companies like (or love) to call an "early adopter" - someone who just can't wait to buy the latest gadget, the faster computer, the bigger HDTV, and anything else you can think of. His obsession definitely has its benefits, though. My sister and I regularly go through his "electronics graveyard" and get fully functional computers, DVD recorders, and all manner of accessories.

But this knack of his to buy the latest electronics makes it that much more difficult to figure out what to get him for his birthday, Christmas, and Father's Day. My sister and I are thinking about buying him a new digital camera for Father's Day, one that has 7.0 megapixels, an optical zoom, and a special setting for taking eBay pictures. Dad is an avid eBay seller, and the right photos can make the difference between selling an item at a decent price and at a great price. The new digital cameras that have the special eBay setting would complement two of his passions: electronics and eBay.

We're also considering buying him a GPS receiver. The Global Positioning System is a set of satellites in orbit high above the earth, and a GPS receiver can tell you, in terms of latitude and longitude, exactly where you are. Some GPS receivers have built-in mapping tools that not only include road maps, but that also show places of interest. So, for example, when Dad's traveling and needs to find a gas station, he can "ask" the GPS system where the nearest gas station is, and then receive directions to it.

A GPS receiver is also perfect for a new "sport" that I've become interested in, and one that I think Dad would love. Geocaching is a hobby that is quite a bit like a treasure hunt. People all over the globe hide small containers that contain trinkets and logbooks, ascertain the latitudinal and longitudinal coordinates of the hiding spots, and post them online. You can go online and find the coordinates of caches near where you live or travel, enter them into your GPS receiver, and then try and find the cache. It's not as easy as it sounds, but it sure is a lot of fun. Once you find a cache, you can pick up a trinket, leave a trinket, and sign the logbook. Dad's expressed an interest in geocaching, and since he does a lot of traveling for his work, my sister and I think that a GPS receiver and a book on geocaching might make the perfect Father's Day gift.

In my heart, I know that our dad will appreciate whatever gift we choose. Any type of electronics will tickle his fancy, and I'm sure that he'll enjoy either a digital camera or a GPS system. The only thing we have to worry about is whether he'll go out and buy one for himself before we get a chance to give him his Father's Day gift!Hidden cameras have become very popular in recent years with business owners, law enforcement officers and parents. Business owners often use surveillance systems to keep an eye on employees or their store to protect the business from theft or abuse. Hidden cameras are used by the police to catch criminals in the act or to record arrests as they occur. Parents use nanny cams to make sure their children are being properly treated. If you're thinking of buying a hidden camera or other type of security camera, here's a quick guide below.

How Hidden Cameras Work

There are two types of hidden cameras - wireless and wired. Wireless hidden cameras use batteries and have the camera and transmitter concealed with no visible wire from the camera to the recording equipment. Wired cameras will have a physical wire running from a VCR or PC to the camera.

To determine if you need a wireless or wired hidden camera, consider the length of time you will need to record. Will the batteries hold up long enough? The location of the hidden camera is also important. Hidden cameras come in a variety of shapes, forms and themes. Choose a camera that goes well with the environment around so it will be unnoticeable. Some cameras feature wide-angle viewing, which comes in handy when you need to survey a large area. Also, the lighting of the area is important. Check the hidden camera's resolution before buying.

Types of Hidden Cameras and Security Cameras

There are many types of hidden cameras and security cameras for all situations. From dummy cameras to professional cameras, each one serves its own unique purpose. Here are some types of cameras and their benefits.

Nanny Cams

Protect your children throughout the day with a nanny cam. Even if you have a nanny you feel you can trust, it doesn't hurt to have a nanny cam for the safety of your children and home. Nanny cams are actually hidden cameras that come in many shapes and sizes. The camera might be embedded in children's items such as teddy bears, backpacks, baby wipe containers, dolls, stuffed animals, etc. These items can be placed in the child's room along with other toys. There are also nanny cams for other rooms of the home, including clocks, radios, table lamps, food containers, thermostats, pillows, picture frames, hair dryers, DVD players, etc. Every room can have a nanny cam if needed. Check with your local law enforcement before getting a nanny cam or hidden camera for your home to be sure there are no restrictions.

Surveillance Systems

If you need more than a few hidden cameras, consider a surveillance system. Surveillance systems enable you to observe multiple locations through one sophisticated system. With a channel DVR system, hidden cameras are set up in different areas and interconnected so you can survey all the areas through multiple channels. You can expand your surveillance system as your business or operation grows. There are also portable DVR surveillance systems and those that enable you to monitor the area from any location online.

Monitors

Monitors are screens that show what is going on as it happens. Many public places have monitors set up to let people know they are being recorded. Some monitors are used by the owners or security guards to keep an eye on areas from behind the scenes.

Dummy Cameras

Dummy cameras are not hidden cameras or even real security cameras. They look like real security cameras and give an appearance that the area is being recorded. The thieves won't know if the camera is real or not. Dummy cameras are often used as a deterrent by many business owners.

Professional Cameras

Professional cameras are often used to survey large businesses or offices, inside or outside. They can be mounted on walls or ceiling brackets. Some are waterproof for outdoor surveillance. A variety of professional cameras are available for different situations.

Hidden cameras and security cameras are great for protecting your children, home, business or property. Use the guide above to find the hidden camera or security camera that's right for you.

The rate of technological development

2007-10-30T02:16:00.000-07:00

If we look over the last century and examine the rate of technological growth. We can forgive ourselves for feeling a little proud about how quickly things have moved forward compared to the previous centuries. Flying at speed. Moving underwater stealthily. Travelling in space to name a fraction of what the human race has achieved in such a short span of time.

The big question though, is could we have progressed any faster and further in that space of time? The answer to that question is a big resounding YES!

Since we have been civilised enough to be able to maintain a system of currency, we have had to rely on that very method of exchange, and commerce has taken full advantage of this situation. In fact, commerce has become so powerful that it actually controls the rate at which we progress.

There are currently three levels of technology in existence.

1) Commercial Technology.
This is the technology we use in everyday life. Covering all manner of toys, tools and useful objects. However, the level at which commercial technology is at. Is higher than that used in commercially available products. Now we could argue that the technology they hold back, is not fully tested, and therefore not completely safe. This might be true in very small percentages. The major reason for holding back is good old money. It's all about making as much money out of a particular product before they move on to the next one. How many times have you seen products advertised as cutting edge at cut price? Only to find that they are outdated months later. Hard selling of latest technology at low prices is a key indicator that commerce is about to release a technologically superior product. So perhaps you can now see the control. What would happen to our technology if this didn't happen?

2) Military Technology.
This is more advanced than commercial technology. There's a lot of military technology we know about, and a lot we don't know about. Governments will hold back the release of this technology into the commercial arena, because it can give them a tactical advantage in a military sense. The components used in military hardware will generally have a longer life than those used in commercial products. I remember having a component catalogue in the 1980's. I could buy standard or military components. Standard were guaranteed for 1 year. Military for 5 years. They are generally more expensive. Commerce avoids using these products. The excuse is cost but it's more likely to be because they want to sell you products at regular intervals. Having a product that lasted for a long time would be counter productive to them.

3) Experimental Technology.
This area is way ahead of commercial technology, but is closely watched by the military. There are developments currently in progress which are things that you possibly, couldn't even comprehend, or didn't even think was in the realm of possibility. The deepest and most secret of these are run by government bodies, and some of them, apparently, don't exist. Again, this is for tactical reasons. If you could see what they were cooking up you would be amazed in one sense, and possibly frightened out of your skin.

So there we have it. After taking all these points into consideration, it's quite obvious to see that progress is thwarted by these processes. Well, let's see what the next few decades bring. Don't worry though. Most of it is already here.

Unlimited PSP Downloads ... Is it a Myth ?

2007-10-30T02:15:00.000-07:00

The PSP is a machine which is a great source of entertainment for you and your family. This is a machine where you can not only play games but also play music, movies; browse the internet and store vital digital data.

It is not necessary that you always buy the music, games and movies you wish to run on the PSP. There are plenty options available on the internet where you can avail of your free PSP downloads.

The PSPs are usually handheld devices where you can transfer the movies, music, software, games, e-books, images and TV shows that you download from the Wi-Fi hot spots of the internet. This is where you can avail of your free PSP downloads for use on the PSP.

The main reason these downloads are called free is because there is no use for you to buy a physical disc to download the programs. They just have to be downloaded to a computer, and then transferred from the computer to the PSP.

The first thing you have to do to get free PSP downloads is to surf the internet for the respective sites. There are many sites on the internet that offer free PSP downloads to PSP owners.

These sites are generally free where you just have to register wherein you can download all the games, music, movies, etc for use on your PSP. These sites have two types of offers; some sites charge a monthly membership fees while others have a once off membership fees wherein there are no limitations on the number of free PSP downloads you make.

In fact, you are also permitted to burn these downloads on a disc.

Collecting unlimited PSP downloads for movies was impossible in the past without burning deep holes in our pockets. Watching PSP movies on your PSP while on the move in the train, car or bus was such an enjoyable experience.

But once the credit card statement arrives at your desk, suddenly reality jolts you back onto earth. Your credit limit has been busted and you instantly realize that you have spent all your money building your private collection of PSP movies and games.
Well, there is a way to avoid this scenario. Let us look at what are the options available if you are tempted to grab your next PSP movie.

We used to be able to watch PSP movies only in the Universal Media Disc (UMD) format. Anyone who has bought a copy of these PSP UMD would know that it is not the cheapest form of entertainment. Many folks felt that they did not really have many choices if they wanted to watch a movie on their PSP.

The UMD movies are expensive and the selection is limited. The technology has made them rather unaffordable to teens, which form a significant percentage of their target market. Naturally, sales plummeted and many studios and distributors are unwilling to release more movies in the UMD format. It is little wonder why the UMD movies could not take off.

Forget about UMD movies. It is amazing how PSP fans came up with creative solutions to this problem. People began to rip movies off DVDs onto their PC before transferring the file into the PSP. It is possible to do so since the movie format is compatible with the Sony memory sticks.

However, there are two shortcomings in this whole process of ripping and copying. Firstly, the memory sticks do not have enough capacity like our hard drives. The quality of the movies is compromised.
Secondly, some DVDs are copyrighted, meaning that they are hard coded and there is no way you can crack them and rip the content off.

You can expect the new DVDs to be coded in such a manner. It seems that the manufacturers and studios have beaten PSP users at their game.

It is rather ironical since these users are part of the movie watching group who has been fuelling the demand for more movies over the years. Then again, its an issue of profits and if you are not paying to rip the movie, they have every right to stop you from doing so.

It seems like PSP users are stuck in a grid lock. Fortunately, smart business people saw the opportunity and established membership sites that offer unlimited PSP downloads of movies, games, music, TV shows, etc.

You may wish to know that at these download sites, the movies come in ready to play format. No ripping is needed. Everything from searching to downloading and playing the movie are compressed into a few clicks of the mouse.

Wholesale Electronics

2007-10-29T00:24:00.000-07:00

Wholesale electronics offers resellers high profit margins along with high volume sales, when done right.

Resellers, whether flea market vendors, eBay sellers, or dollar stores, will be faced with competition from online and offline retailers who can buy wholesale electronics at a lower price.

To outmaneuver this competition in the wholesale electronics business, resellers need to have a strategic plan in place.

Part one of their plan deals with finding the best sources for wholesale electronics at the lowest possible prices.

For this reason I would recommend resellers to stay away from drop shippers when looking for wholesale electronics.

Since the drop shipper is set up to offer his products to thousands of other resellers, you will not be able to compete based on price. All the resellers are paying the same price to the wholesale electronic drop shipper, so how can your prices be lower?

When looking to buy wholesale electronics you want to get as close to the source as possible.

Since you will not be able to buy brand name wholesale electronics for a lower price than major retailers can, you will want to look for lesser known wholesale electronic sellers.

For instance, ABC Electronics might not have the name recognition that Sharp enjoys, but you can show customers that the quality is the same, and as long as your prices are lower some customers should buy the wholesale electronics manufactured by ABC Electronics.

When you contact these companies looking for wholesale electronics ask them for their overstock, overrun, and closeout deals. You would be surprised at the wholesale electronics deals you can find from small manufacturers that are looking to move merchandise out.

You can find great wholesale electronics deals but it will take some solid leg work.

Donny Lowy is the CEO of http://www.closeoutexplosion.com, an online wholesale and closeout business, and http://www.wholesalecloseoutforum.com, an educational site for the wholesale and closeout business.

Electronics Show Influences Still Reverberating

2007-10-29T00:23:00.000-07:00

The CES (International Consumer Electronics Show) for this year may be over, but its after effects are still reverberating around the blogosphere and beyond. Electronic giants, Media conglomerates, Satellite Television Companies, HDTV (High Definition Television) manufacturers and everyone else in the digital universe attend the CES. The CES is the premier location for them to show their wares. How we sit on the cusp of the transition from an analog to a digital world was one of the big topics explored this year. From the popularity of all-digital Satellite Television, digital video cameras and the newest digital televisions, we see proof that the transition is very real. Monumental changes are happening in the entertainment world. Mobile TV or streaming video on the handset or cellular phone was another one of the stars at the CES.

Another topic was the fact that consumers are purchasing, recording, saving, using, moving and creating more of all types of digital media. The emerging digital lifestyle is changing all of the time and one way that companies try to get a handle on this shifting universe is doing research. One small, but very important method, is for the experts to actually come to your home! They call it Environmental Observation Research. They come to your home (with permission) and bring digital video cameras and watch you interacting with your digital stuff! They also conduct interviews and in general snoop around and try to discover all that they can about the home entertainment habits of consumers. Anthropologists call this ethnographic research and they do the same thing, except that they stay around for a year or two.

Some experts in the industry are worried that consumers are falling behind in their knowledge of the new technologies. For example, many consumers confused HD television with Digital Television. Some erroneously thought that HDTV was coming in about two years. Plasma television was also a source of confusion for some—one consumer thought that he would have to spend 20,000 dollars to get a plasma set. Most consumers knew little to nothing about DVR technology (Digital Video Recorders). After they were told that DVR’s allow you to record and pause live television and replace and improve the old VCR technology, they could readily understand it. However, this research underscored the lack of information in large segments of the population. Interestingly, the researchers found out that every household has an unofficial IT manager, and they are the go-to person when someone in the family needs help and information on a new topic or device. I just bet you are the IT expert in your home, aren’t you?

One of the largest lessons from the CEA: Back up your digital memories, files, photos, and videos… And do it now! This is a poorly understood and poorly actualized area. Most consumers just aren’t aware of the importance of backing up, and furthermore they don’t know the technologies to back up their files, such as burning data discs, having copies at other locations, and storing their information on the Internet. Do not lose those precious videos!

Electronic Locks - Revolutionizing The World Of Door Locks

2007-10-29T00:17:00.000-07:00

You are not safe behind locked doors. Yes, you definitely aren’t. With thieves and burglars getting hold of every possible way to get past doors locked with the conventional mechanical locks, locked doors aren’t safe enough anymore. A simple twist and the conventional locks give way. But now there is hope, and it has found the form of a great new technology – Electronic Locks. An electronic lock, as the name suggests, is a device using a certain form of electronics to authenticate the identity of every person it. Electronic locks are more secure than conventional mechanical locks. Electronic locks are definitely a step ahead of conventional mechanical locks with regards the level of safety offered. Electronic locks provide many advantages over conventional locks which can be aptly termed to be “electronic lock services”. For example, electronic locks offer a log of successful attempts in getting past them, as also a log of failed attempts of sneaking through them.

Electronic locks can be used almost everywhere. Unlike conventional locks, electronic locks come in a variety of shapes and sizes. The best application of an electronic lock is to use one as a door lock. Electronic door locks are undoubtedly the best amongst all alternatives available today. Electronic door locks, like a lot of electronic lock have a magnetic lock to use it manually. Also prevalent is the use of other older mechanisms which often use an electronic motor to move a deadbolt. Electronic lock services require providing electrical currents to the lock. Providing electrical currents to a lock within a door can be difficult. Hence a common solution to this is a use of an electronic strike plate.

Electronic door locks score over other mechanical locks due to the fact that electronic locks provide a variety of means of authentication such as the use of Numerical codes, passwords and pass phrases, Security tokens, Biometrics etc. An electronic lock service using numerical codes for authentication is the most prevalent form of electronic locking. In these kinds of electronic locking services, the correct code must be entered in order for the electronic door lock to deactivate. These kinds of electronic lock services typically provide a keypad, and some electronic door locks also feature an audible response to each press. Combination lengths are usually between 4 and 6 digits long. The larger the combination, the stronger is your electronic door lock. Electronic lock services are also available with a slight variation to the above. The variation on this design involves the user entering the correct password or a pass phrase to deactivate the electronic lock.

Another means of authenticating users used in electronic locks is to require them to scan or "swipe" a security token such as a smart card or similar, or to interact a token with the lock. Biometric electronic lock services are the latest in electronic door lock systems. Such electronic locks use features such as scanning of fingers, fingerprint scanning, eye scanning, and security features such as voice recognition etc to authenticate users.

What are the best features of a portable DVD player?

2007-10-27T05:20:00.000-07:00

A great movie can make a long trip go by very easily, especially when flying. Often however, the movie you watch on the small screen at the front of your cabin is edited and interrupted by announcements from the crew about dinner. Have you ever considered taking a portable DVD player with you? With one of these and a good set of headphones, you can enjoy that action flick while everyone else is stuck hearing about the Grand Canyon. Check out our list of recommended features below to help you choose the best portable DVD player.

* Dimensions A portable DVD player can end up feeling like a small brick to some, especially those which have large rechargeable batteries attached to them. While all players tend to run small, weight can vary by several pounds so make sure to check the side of the box before you buy.

* Disc Formats Supported Besides playing standard DVDs, many portable players today can double as CD players as well, eliminating the need to take one extra device on your trip.

* You should also consider seeing if your player can support CD-R,CD-RW or DVD-R as well, as these do-it-yourself disc formats are becoming popular amongst those who have burners at home.

* Outputs One of the great things about portable DVD players is that they can substitute for regular size cousins on the fly when you need to plug into your home entertainment system. You'll want to consider a player which has high quality outputs, such as S-Video for video and Optical Out for audio, so you can get the best quality playback possible.

* Screen Many players today come with built-in screens, which make it the ultimate DVD entertainment device for the road. While screen size varies somewhat, larger is definitely better. You should expect to pay a higher price however. If you are looking for budget, you can also consider a player without a screen, though you'll need to make sure you have something you can hook it up to so you can watch your movie.

* Virtual Surround Sound For those times when you don't have the ability to hook your DVD player up to a home entertainment system, consider a model which has virtual surround sound. This neat feature enhances the sound quality of the movie, giving it a more realistic edge.

Now that you have down the basics about what makes a great portable DVD player, put your skills to the test by browsing our Top Portable DVD Player picks and choosing the player which best fits your needs.

True vs 'PMPO' Power

2007-10-27T05:19:00.000-07:00

1 Introduction

The term '''audio power''' is used in the specification or measurement of audio amplifiers or loudspeakers. A meaningful and reliable measure of the power output of an audio amplifier, or the power handling of a loudspeaker is ''continuous sine wave power'', or more strictly 'continuous average sine wave power'. Such a figure will often be found in advertising literature referred to as "true RMS power", but this is quite incorrect. Although there is such a thing as RMS (root mean square) power, it is neither useful as a measurement nor what is intended by those who use the term. The sine wave power is found by averaging the instantaneous power output over a long period of time (or one complete cycle), so it is actually the ''average power'' or ''mean power''. The term RMS is used mistakenly due to the fact that the mean power is calculated from the RMS voltage and current (or one of them and the impedance); power being proportional to the square of voltage or current.

2 ‘Music Power' - the Real Issues

The term ''"Music Power"'' has been used in relation to both amplifiers and loudspeakers with some validity. When live music is recorded without amplitude compression or limiting, the resulting signal contains brief peaks of very much higher amplitude (20 dB or more) than the mean, and since power is proportional to the square of signal voltage their reproduction would require an amplifier capable of providing brief peaks of power around a hundred times greater than the average level. Thus the ideal 100-watt audio system would be capable of handling brief peaks of 10,000 watts in order to avoid clipping (see Programme levels). Most loudspeakers are in fact capable of handling peaks of several times their continuous rating (though not a hundred times!), since thermal inertia prevents the voice coils from burning out on short bursts. It is therefore acceptable, and desirable, to drive a loudspeaker from a power amplifier with a higher continuous rating several times that of the speaker, but only if care is taken not to overheat it, which is difficult, especially on modern recordings which tend to be heavily compressed and so can be played at high levels without the obvious distortion that would result from a 'real' recording when the amplifier started clipping.

Music power is a less valid term when applied to most amplifiers. Most power amplifiers can give more output on brief bursts than their continuous rated output, but not usually to an extent that is relevant in the context of the above. There are three reasons for the enhanced short-burst power.

Most amplifiers do not have regulated power supplies but rely on a full-wave rectifier and large smoothing capacitor to provide a reasonably steady supply voltage. This charges to its peak voltage on quiet passages where little current is being drawn, but 'sags' to around 10% less under heavy current demand. Since 10% voltage drop corresponds to 20% power drop, the steady-state power output of the amplifier, which has to be quoted is always some 20% lower than the brief power capability. A 100-watt amplifier is therefore likely to handle brief peaks of up to 120 W without clipping. This might sound good in a specification, but it should be noted that it is only 1 dB, which is a change in level not usually even detectable by the human hearing system! It is also usually only available for some 10 milliseconds, which is too short to be of much benefit in real programme material. The term peak music power, in this context, is of no real significance.

It is possible to take a cost-effective approach to power amp design by reducing the size of the heat sinks on the output devices below that needed to avoid overheating on continuous sine wave drive at maximum output. Such an approach was once valid, as it recognised that fact that on 'real' recordings there is no need to provide for continuous full output as the gross distortion caused by clipping on brief peaks will result in the user turning down the volume before damage is done. On modern amplifiers it is possible to take such an approach without risk of damage, using integrated amplifier chips, which tend to incorporate 'thermal protection'. However, the trend towards heavy compression and limiting on commercial recordings in recent years means that people expect to play these at high volume without clipping, and so the validity of the 'peak music power' approach to amplifier design has mostly been removed.

While the above is true for most 'domestic' amplifiers, it need not be so, especially in relation to monitoring, and uncompressed reproduction. Some professional amplifiers, and 'active' speakers, incorporate sophisticated electronic thermal protection circuits which integrate the power delivered to the speaker and take account of its thermal capacity properly. This enables them to handle peak power levels safely while limiting the continuous power that can be applied in a way that makes sense.

3 Power Handling in 'Active' Speakers

Active speakers often use two or three power amplifiers, each handling only part of the audio frequency spectrum. The main benefit of this approach is that it enables complicated crossover filters to be used on the low level signal, and eliminates the bulky and awkward inductors and capacitors normally used in crossover networks. There is, however, another big advantage that is not usually recognised. When two tones are reproduced simultaneously, a single amplifier normally has to handle the peak power that results when both are at their crest. Because of the square-law relationship, this means that two tones each generating 10 watts result in a power handling requirement of 40 watts. With multiple amplifiers, the two tones can be handles separately, by 10 watt amps. Thus a 'bi-amped' system can handle peaks of up to twice the combined rating of its amplifiers, and a 'tri-amped' system, on three tones, gains even more! This is of course because the signal has a high 'crest factor'. In practice, music peaks often consist of percussion riding on top of bass notes, and so the benefit is very real, as these are each always handled separately. This is a benefit that would cost a lot to realise if the single amplifier approach were taken, making 'bi-amping' a very cost-effective approach.

4 US Market Regulations

In the US on May 3, 1974, the Amplifier Rule CFR 16 Part 432 (39 FR 15387) was instated by the Federal Trade Commission (FTC) requiring audio power and distortion ratings for home entertainment equipment to be measured in a defined manner with power stated in RMS terms. This rule was amended in 1998 to cover self-powered speakers such as are commonly used with personal computers (see examples below). This regulation did not cover automobile entertainment systems, which consequently still suffer from power ratings confusion. However, a new regulation called CEA 2006 includes car electronics, and is being phased into the market as slowly as possible by many manufacturers.

Unfortunately there are no similar laws in much of the rest of the world.

Videogame Systems Top 'Planned Gift' Lists This Year

2007-10-26T05:54:00.000-07:00

According to research by the Consumer Electronics Association, sales of consumer electronics are expected to top $22 billion this holiday season, with videogame systems topping the list of gifts people intend to give to others. Though consumers are expected to cut down on expenses like home decorations and travel, they'll still be spending plenty on gifts.

Not surprisingly, videogames made the top five most wanted items for teens, along with clothes, computers, MP3 players, and cell phones. Adults who were hoping to get some kind of electronic gizmo for the holidays put game systems on their wish list beside MP3 players, laptops, TVs, and digital cameras.

Wear your electronics

2007-10-25T05:03:00.000-07:00

An electronic revolution could be on the way with the development of a thin film of plastic that conducts electricity and produces solar power, changing the way we light our homes and design clothes.

An international research project has begun that could bring organic light emitting devices (OLEDs) to the mass market.

The devices are thin and flexible, which means that lighting and electronic display screens could be created on almost any material, so that clothes and packaging can display electronic information.

The devices' uses vary from lighting that is more efficient than current bulbs to clothes which change colour at the press of a button and beer cans that display the latest football results.

At present, the devices are used as displays in some mobile phones and MP3 players, but they are not reliable enough for larger screens such as TVs and computers as they stop working after a few months.

"Their use in large televisions, clothes, lighting etc is longer term: 1-3 years away for televisions; 2-5 years for clothes; maybe 5-10 years for lighting and large displays," Dr Alison Walker of the British University of Bath's Department of Physics said.

An international consortium of researchers, led by the university, has begun a three-year project to put the science behind the devices on a firmer basis, so helping make them efficient enough to be mass produced.

The consortium, called Modecom, consists of 13 groups from nine universities and two companies. Three groups are from Britain, six from the US and one each from China, Belgium, Italy and Denmark.

"The consortium is funded by the European Commission," Walker said.

"Modecom's output is primarily scientific and will be published in the open literature and presented at international conferences so will be accessible to Australian researchers."

The devices make use of a discovery made 15 years ago that some polymers have the property of either turning electricity into light, or light into electricity, depending on how the devices are made.

Because these polymers are thin and flexible, they could be used in a multiplicity of ways:

*

As a transparent window. This is like a conventional window during the day, but when it gets dark a switch is turned on and the entire window area emits light in a more efficient way than conventional or energy-saving bulbs, promising huge savings;
*

In clothing which displays strips of the polymer which run off solar power, allowing electronic messages to be displayed which can be updated. This could be useful for the emergency services;
*

In packaging for common goods that could be made to display electronic messages such as health warnings and recipes or could emit light;
*

As a source of solar power to top up mobile phone batteries;
*

As lightweight, solar power sources that could be rolled up and stored and which would also be suitable for people requiring electricity in remote locations, such as field researchers, mountaineers, sailors and military personnel.

However, Walker doesn't think this technology will replace traditional solar power sources as they are very inefficient.

Their key advantage is cost: they are cheap and their energy cost in manufacture would also be low, so the devices themselves will cost a few cents. They are also portable and flexible so their main use would be to replace batteries that, according to Walker, could happen in 5-10 years.

Walker goes on to say, the main thing holding the technology back is efficiency and degradation for displays, lighting and clothing and for solar cells, efficiency, then degradation.

The polymer is made from chains of molecules, and is called organic because they contain carbon. Electrons and holes injected into the polymer film form bound states called excitons that break down under electrical current, emitting light as they do so.

Walker's part of the consortium's research uses a mathematical technique called Monte Carlo analysis in which computer-generated random numbers are used to plot the paths of electrons, holes and excitons as they move across the film.

The results from this can be used to calculate how the chemical structure and impurities affect the device's performance. Chemists can use this data to design more efficient materials.

The Modecom consortium will work on the molecular level and also look at the workings of the device as a whole. This research will aid the understanding of the polymer materials used in plastic electronics in applications such as electronic paper and intelligent labels on groceries.

A Helmet Camera Captures All of Your Daring Feats

2007-10-24T05:05:00.000-07:00

If the spirit of adventure runs through your veins, a helmet camera can help you capture all of your daring feats, whether for motocross, flying, ATV, road racing, kayaking, skydiving, cycling, snowboarding, karting, or other adrenalin-pumping sports.

Helmet cams give you the capability to record every moment of the action without depending on an outside cameraperson. These action video cameras are popular with television and movie recordings as well as daredevil athletes, and now you can record your feats just like the pros! You can show the recording to your friends, and they can imagine being there with you on every twist and turn.

What is a Helmet Camera?

A helmet camera is a very small type of camcorder that can be attached to a protective helmet to record all the action while doing extreme sports activities. It can also be used for more relaxed sports such as fishing, golf, hiking, and biking. Helmet cameras are also called helmet cam, bullet cam or bullet camera, lipstick cam or lipstick camera (resembles a tube of lipstick), or wireless helmet camera.

A helmet camera works in conjunction with a DVR (DVD video recorder) and can be played back again and again for your enjoyment.

Benefits of Helmet Cams

Helmet cams provide hands-free recording during your extreme sports activity. This promotes safety and easy use. You won't have to worry about holding the camera or adjusting it as you go. You can concentrate on the activity and still capture all the details without distraction. Also, you can record sound with a helmet camera and narrate the activity as you go. If you're participating in an extreme sporting competition, you can record every moment as a keepsake for years to come.

Buying Helmet Cameras

When you get ready to buy a helmet camera, check online for a dependable retailer. You can always find great deals on quality lipstick cameras with all the accessories to go along. Search for helmet or bullet camera reviews to find good quality products. Also, check for sound quality, durability, and features before buying. Sometimes paying a little more is well worth it if you get a better quality helmet camera. There are affordable, high-quality cameras available online such as the Oregon Scientific ATC-2000 action adventure cam.

Tips for Using Helmet Cameras

Once you buy a helmet camera, take time to study on how to use it properly. Be sure the helmet cam has been properly secured before starting your activity. High speeds, bumps, and falls can cause the helmet camera to become lost or broken if you don't secure it properly. The camera's cable should also be secured so that it doesn't flap in the wind. Take quick breaks to check the lens to make sure it's clean if you're out on the road or in the dirt, water, or mud. Also, be sure the camera is actually recording before getting started!

For the Holidays, Go Online to Buy Hot Consumer Electronics

2007-10-24T05:03:00.000-07:00

Experts are forecasting that, again this year, consumer electronics will top wish lists in the upcoming holiday season. And, although some shoppers continue to favor brick-and-mortar stores, an increasing number of consumers are finding better prices and greater selections of consumer electronics through online stores.

There are three categories of consumer electronics that are forecast to be especially hot this holiday season:

Gaming Systems

The recent launch of Halo 3 left no doubt among entertainment industry experts that video games and video game consoles can rake in more money than Hollywood movie premieres. With over $3 million in sales the first week, Halo 3 - the Xbox 360 signature game - dealt Microsoft a winning hand.

But the Xbox 360 isn't the only gaming system set to heat up during the holiday gift giving season. With its enhanced physicality and interactive community, Nintendo Wii is still considered the breakout gaming system of the decade. From the compelling Wii characters to the dexterity-challenging Nunchuk, every aspect of the Nintendo Wii is engaging and enchanting.

Although in some circles Sony's PlayStation has been left holding the bag, PS3 gaming systems are still hot commodities, especially for families with children. As some of the other gaming systems have skewed their video game releases to the teenage and adult markets, PS3 and PS2 systems have remained home to a vast array of kid-friendly games.

Cell Phones

Although cell phones are ubiquitous, they continue to be in demand. And, despite the hoopla associated with this year's launch of the innovative Apple iPhone, this holiday season will find most shoppers buying established cell phone brands like Nokia, Samsung, and Motorola.

Music and Video Players

When it comes to consumer electronics and the holidays, more people than ever before will be unwrapping music and video players. Apple iPods are expected to be in high demand, as will portable DVD players. And, with an increasing number of people becoming familiar with DVD recorders' multitude of features, DVD player/recorders will also be hot commodities this holiday season.

Buying Consumer Electronics Online

Because online stores don't have the overhead expenses associated with retail brick-and-mortar stores, they are often able to offer the most popular consumer electronics at rock bottom prices. Plus, online store offer the added bonus of allowing consumers to comparison shop in order to find the best deal on gaming systems, cell phones, and music and DVD players.

For example, some online stores will offer a variety of video games bundled with an Xbox 360, which can literally save consumers hundreds of dollars. Aside from bundled systems and other bargains, there are other factors to consider when choosing an online store to buy consumer electronics. These factors include real-time ordering and online inventory (so your gift won't be stuck on backorder), warehouse shipping (rather than having to wait for a middleman to ship the merchandise), and exceptional customer service (such as timely communication and non minimum purchase requirements).

When you find the right store, shopping online for consumer electronics can be a breeze - and a bargain!

Safely Setting up and Using a Residential Standby Generator

2007-10-19T05:02:00.001-07:00

One of the most tragic stories after a big storm is the inevitable tale of a family that was poisoned by carbon monoxide or electrocuted by an improperly installed or operated standby generator. These tragedies can be easily avoided by just following a few simple rules to ensure adequate isolation and ventilation.

Since they are most often used in the event of a storm or weather related events, residential standby generators are often forgotten until they are needed. This is, of course, the wrong time to find out that the suggested maintenance regime hasn't been properly followed. A improperly maintained generator may simply not start, send a spike that damages all your equipment and sometimes unlucky operators suffer severe shocks or burns. Careful testing when the storm season can mean the difference between being prepared or not.

However, it's not such a major project to maintain a standby generator that's only used in emergencies. This can usually be accomplished in a once-per-year check. When properly stored outdoors and undercover - an outbuilding or shed is an ideal location - this will likely entail little more than annual attention to the oil. In the case of portable generators or those systems used on a very regular basis, it's best to check on them on a more regular basis as you might an automobile.

In the case of gasoline or diesel generators, they should be treated like motorcycles being put away for the winter. If left alone, the fuel could turn into varnish and render the engine useless. There is likely a recommended maintenance regimen for managing the storage of fuel, that came with your standby generator, as generators from manufacturers such as Winco, Gillette and Pramac do. A yearly draining or treatment with an octane stabilizer is the usual course.

Portable generators are very nearly always gas, diesel or propane and require no major installation. However, it's often a good idea to have them on wheels since even so-called portable generators can be quite heavy. Most residential generators are at least semi-portable, so they may be moved into a suitable position before a storm or they may be essentially anchored to a location in the backyard. Thanks to modern satellite weather, such disasters are rarely a total surprise, so there is almost always time to bring the generator into position for use if necessary. Portable generators are often brought into the home or basement to ride out the storm in the case of severe weather.

Since appliances and devices will be plugged directly into the generator, you'll also need some thick gauge extension cords that are free of defects and nicks. Never try to plug the generator into your house grid. This is dangerous and rarely effective. It is unlikely you took every single appliance in the house into consideration, and the possibility of having no power at all is very real.

Heavy duty power-strips are suitable, but be sure and check on the maximum recommended current levels for any given device. You can easily figure this out if the rating is not given in watts. Since you know how much power (in watts) will be used, you can easily figure out the current (measured in amperes or amps) by dividing the number of watts by 110 volts (in North America) or 220 volts in the rest of the world.

Another type of problem that can occur is the result of a gas or propane generator that isn't properly installed. Natural gas powered standby generator installations are stationary by definition. The additional need of “plumbing” for the gas lines and valve maintenance is sometimes problematic and absolutely must be attended to yearly and inspected on a regular basis. If one isn't familiar with such work, it is often best to include the price of hiring a professional to assist in the install in your purchase price of this type of residential generator.

Most generators take as long as half a minute to power on completely. You can rely upon the protective circuits of a new standby generator, but with older models, they could be faulty, and that means disaster. Also, when large devices that have lost power and discharged completely, the initial power up could result in current draws that are nearly three times the normal load, as the very large capacitors fill back up like sponges.

When turning on a residential generator, a good plan of action is to let the generator power up for a moment, until operation stabilizes. There is very often an indicator that monitors the electrical performance. When everything is all settled down, you can then plug your essential items in one at a time.

Of course, for very expensive or critical gear, such as computers or medical equipment, it is imperative to have a battery backup system that will keep these devices running while the standby generator can be coaxed into life.

Maintaining and carefully operating a standby generator will allow you to feel confident when storms are bearing down upon your community. From the massive natural gas generators that power hospitals to wheeled and portable generators keeping your frozen food from melting, each has its own set of concerns.

Plasma TV Wall Mount

2007-10-18T05:23:00.000-07:00

For those who want their home theatre to imitate the cinematic experience, a plasma TV wall mount is a good investment to save space and to give a great effect. A plasma TV wall mount is easy to install yourself, but if you prefer, you can hire a professional to do the job for you. The price of a typical plasma TV wall mount can range from $60 to $350, and it is a good idea to invest in the best plasma TV wall mount you can afford, since plasma TVs are quite delicate and you cannot risk having your plasma TV fall to the ground. However, most plasma TV wall mounts do the job sufficiently well.

Your plasma TV wall mount should contain at least the following items:

• Wall plate
• Rails
• Arms

The wall plate attaches to the wall and the rails are for the back of the television. There should be two perpendicular arms with devices to connect to the back of the plate. The rails enable you to move the TV to the right or the left across the wall and enable you to lift the TV off, if necessary.

You need to select a plasma TV wall mount suited to the type of plasma TV that you have. The average size is 26-41” and weighs up to 100 pounds. A typical plasma TV wall mount can handle this type of set. However, if you plasma TV is larger than this and weighs more than 100 pounds, you will need a two stud wall mount.

It is possible to install your plasma TV wall mount on a concrete wall, although you will need a different type of plasma TV mount. Cement anchors are needed to keep you TV in place on a concrete surface, and you can also find long belts and other devices specially designed for concrete. As with any type of Plasma TV mount, ensure that your cement anchors are sturdy enough to hold a heavy unit.

When you install your plasma TV, you might not be certain about what height you want. If you have a typical, flat plasma TV wall mount, you will need to put your plasma TV at the correct height. However, many people like to have their plasma TV’s a little higher. One reason is that, since plasma TV are so vulnerable to damage, those with children prefer to put their plasma TV as high up as possible to avoid stray balls from hitting the screen. If you want to put your plasma TV up high, you will need a special plasma TV wall mount that tilts so your set can face downward at an angle. You will also need a tilt plasma TV wall mount if your set is not completely flat, but has a gentle curve at the back.

You can purchase a plasma TV wall mount with fixed arms or with articulating arms that move along a 90 degree swivel. The articulating wall mounts may cost a bit more, but are worth the investment if you like to view your television from different angles. They are not much more difficult to install than fixed arm wall mounts, and are just as durable.

Ensure that your plasma TV wall mount is sufficiently durable. It is a good idea to install your television along with a friend who can help you take your plasma TV on and off the mount while you are testing it for durability. A partner can also see if there is any “giving” or wobbling, and this second pair of eyes might just save your set. If you are unsure of your abilities, it is worthwhile to hire a professional to install your plasma TV mount.

Plasma Flat Screen Television

2007-10-18T05:22:00.001-07:00

The plasma flat screen television was invented in the 1960s, and although it made a brief appearance in the market in the 70s, it did not quite catch on. Nowadays, the plasma flat screen television is defining what a home theatre should be, and most people who pride themselves on having a fine home theatre own a plasma flat screen television along with other high-tech innovations, such as surround sound speakers. The plasma flat screen television truly gives one the feeling of sitting in the cinema, and, if mounted on the wall, it can save a lot of space. Although the price was once out of the range of the average consumers, plasma flat screen televisions are slowly moving into the range of affordability.

A plasma flat screen television uses technology that is quite different from the typical cathode ray television. Neon and Xenon gases move between two flat panel glasses. These are inert gases and are not dangerous. The result is amazing color; the typical plasma flat screen television produces 16 million unique colors and provides great contrast between dark and light. The screen has a “perfect black” that gives it a cinematic feel. Although the plasma flat screen television is much larger than the conventional television, with all of its devices, it is usually no more than four inches thick. This allows one to install a plasma flat screen television on the wall to save space.

Although the cost of a plasma flat screen television keeps decreasing, you should take into account the amount of power these televisions can use when you figure out the cost in real terms. While there are many energy-efficient models, a larger plasma flat screen television uses a lot of electricity. However the technology of the plasma TV is being developed and improved constantly, and, before long, using a plasma TV will conserve energy.

One advantage to the plasma flat screen television is that it has a relatively long life; the typical set has 60,000 hours to half life (half-life occurs when the screen quality is reduced by half). When you purchase your plasma flat screen television, ensure that you have an excellent warrantee and that you can have it serviced for free or at a low cost.

One thing to be aware of with your plasma flat screened television is that it is quite delicate, and the slightest bump can cause problems. For instance, if a child throws a ball at the screen, hundreds of individual tubes can lose their ability to glow, and repair for this is expensive, if it is possible. It is therefore a good idea for parents to install their plasma flat screened television so that it is high enough to avoid such interference (and don’t let your kids play ball in the TV room!). There are tilt wall mounts that allow you to install your plasma flat screened television at an angle if you store it high.

Along with the plasma flat-screened television, you can purchase plasma furniture or special cabinets and stands for your plasma television. If you prefer the classic, hardwood look, there are home entertainment cabinets specially designed to hold plasma flat screened televisions along with other equipment. For a more contemporary look, you can find metallic curved stands with simple glass shelves or just a short stand to place on top of an existing cabinet or table.

An important tip to keep in mind when choosing plasma flat screened television furniture and supplies is that they should be well-tested for sturdiness, since a plasma TV cannot handle a bump, much less, a complete fall. Make sure that all surfaces and mounts are sturdy enough to hold your set or more weight, just to be on the safe side.

3 Simple Ways To Save A Bunch Of Money When Buying A New Computer!

2007-10-16T05:16:00.000-07:00

Looking to buy a new computer?

Overwhelmed by all of the options available to you?

Stressed by the high cost of computers today?

For most people, buying a new computer does not have to be as stressful as buying a new car. Nor does it have to be as expensive. If you’re like most people, and you have a limited budget for buying a computer, then you need to try to get as much computer for your money as possible.

Here are 3 simple ways anyone can save money when buying a new computer:

1) Shop around for best deal.

Sounds pretty obvious. But many people don’t realize they don’t need the fastest, most expensive computer with the most “extras”. In fact, if you are already using an older computer, even the least expensive new computer will be a big upgrade. If you don’t know a lot about computers, you can learn a lot by shopping around. Ask lots of questions, compare prices, compare features, then find the best price. Shop at your local electronics store, and look for the best deals online. You’ll be surprised at how much money you can save by shopping around!

2) Install your own “extras”

Many computers you will find in a store have a lot of extra software already installed. While this is convenient, it is not always the best way for you to save money. Also, while many of these extras sound good, you don’t always need them. You can often find better deals by shopping around separately for your own software extras (such as a word processor, anti-virus, popup blocker, spyware removal, games, etc). And some of these you can get for free. So before you buy the “fully loaded” computer, ask yourself if you really need all the extras, then shop around to see if you can buy a scaled down computer - and get the extras yourself for much less!

3) Don’t buy extended warranty

If you are not a computer “techie”, the extended warranties offered by the computer retailers often sound like a good idea. After all, who wants to be bothered paying for service on a computer after you buy it. But keep in mind that most computers come with a warranty, and most computer problems will either happen at the beginning (when you still have the warranty in effect) or much later (when it might be cheaper to buy a new computer). Technology changes very quickly these days. So consider whether or not it’s worth the inflated price of the extended warranty. And, if you really feel you need the extended warranty, then ask to purchase it at a lower price. Not all retailers will negotiate on the warranty, but some will. And whether you buy the extended warranty or not, make sure you back up all your files periodically, just in case!

If you have an unlimited budget, consider yourself lucky. And if you do business on the computer, make sure you get what you need, while trying to keep the price down. At any price, buying something that does not fit your needs is not a good deal.

Hope you find these tips helpful, and happy computer shopping!

Hitachi 55PMA550E TV - Style and Sophistication By The Bucket Load But at a Price?

2007-10-15T06:12:00.000-07:00

Getting a new television for the home is a major purchase nowadays. The idea of parting with what could be a couple of hundred notes does tend to concentrate the mind somewhat.

Ensuring that any purchase you make is to all intent and purposes future-proof has to be the most major of all criteria when deciding which TV to buy.

Digital television (DTT) is a telecommunication system for broadcasting and receiving moving pictures and sound by means of digital signals, in contrast to analogue signals used by analogue (traditional) TV. Introduced in the late 1990s, this technology appealed to the television broadcasting business and consumer electronics industries as offering new financial opportunities.

With this article the aim is to take a look at what is on offer with the latest generation of Flat Screen Televisions and in this case the Hitachi 55PMA550E.

The 55PMA550E is a 55in Plasma TV and the prices for these would be in the region of 3500 pounds sterling or 7000 US dollars. The resolution of the screen is 1366 X 768 and with regards to being HD Ready the answer is yes. The Hitachi has 1 (1 RGB) scarts and the type and number of Multimedia interfaces the 55PMA550E uses is DVI and 1. The type of Tuner for this TV is Analogue and the Hitachi is available from a wide variety of outlets.

All these points being taken into consideration, how would we view the Hitachi 55PMA550E?

Well to start with our score for the picture quality is 10 out of 10, and for the sound quality we would rate it at 8 out of 10. Another useful aspect to review is the availability and number of relevant connections and our score here would be 10 out of 10. With regards to the overall level of features, our view would be 10 out of 10 and for ease of use and overall value for money we would give it, 8 out of 10 and 10 out of 10 respectively.

The overall verdict would be that this Plasma TV has we feel got performance, style and sophistication oozing out of every connection but this has to be balanced by the fact that it is not the cheapest Plasma screen available.

It is extremely unlikely given the variety and range of makes and models available that you will not be able to find something to match your tastes or budget. You could either opt for one of the more cutting edge newer options available or stay safe and go for one of the more established options available. We hope that after reading this article you will find yourself better informed and as such it will mean that really it will not matter which rout you take.

Please be aware that the prices quoted in this article are taken from a number of leading e-commerce websites and as such should be taken as guides and indications of prices rather than absolute quotes.

Home Theater Projectors for the Cinephile in You.

2007-10-13T00:18:00.002-07:00

Over the years, I have grown really attached to my home theater system. I must say, of all the rooms in the house, my own little movie theater is the one I could not live without. I am absolutely in love with my home theater system and, if you are anything like me, I am sure you will love yours too. I found, when I was initially building my system, that there was so much information to absorb. Every product out there seemed better than the next, and I found myself unsure about which to buy. Here are a few things to keep in mind when shopping for a new home theater projector.

There are two main types of projectors on the market; DLP and LCD. DLP stands for digital light processing. It was invented by Texas Instruments, and utilizes a microscopic array of over 2 million mirrors. DLP has a higher contrast than LCD, but there are some unfavorable consumer reports that note something called the "rainbow effect". The "rainbow effect" is noticeable when looking from one side of the screen to the other, and is characterized by a sudden burst of color.

LCD stands for liquid crystal display. These projectors have three distinct glass LCD panels inside; one for each component of the video signal (red, green, and blue). While DLP chips reflect light, the LCD panels allow light to pass through them. LCD projectors produce brighter images, and they are known for having excellent color saturation. In the end, you will be hard-pressed to notice a great difference between the two types of projection systems.

When shopping for a new projector, keep your particular needs in the forefront of your thoughts. As I mentioned above, it is really easy to lose yourself in the minutiae of each particular system. Connectivity is a definitely something to be mindful of. Make sure that you are able to connect all of your components, including your gaming system. Nothing beats playing Halo in real-life size! Contract ratio is another important factor; the higher the ratio, the better the picture will be.

The brightness of your projector is another thing to consider. Light output is measured in ANSI (American National Standards Institute) lumens. You will want to avoid a projector that produces anything shy of 1000 lumens. As you are likely aware, the projection resolution is extremely important. This refers to the number of pixels that can be displayed on the screen. Go for something that is no less than 1024x768, as this will allow you to fully appreciate the depth and quality of HDTV. In the end, you should buy the projector that is in line with your needs and your budget. Soprano's is coming on right now! Time to go!

What is Surround Sound and Why Do You Want It?

2007-10-13T00:18:00.001-07:00

Whether you are an audio novice or an experienced technophile, this article is for you. Let’s take a few minutes to review the basics of surround sound, and the principles behind it. If you are new to surround sound, this will help you to understand the concept. It will also refresh the memory of those already in the know. These are the basics of sound.

Monophonic sound is single channel and unidirectional. Basically, this means that your audio is all filtered down into a flat single channel. All elements of the recording are mixed down into one source, thereby seeming to originate from the same source no matter where you are standing in the room. This is old school, kids.

Stereophonic sound is reproduced through two channels and is considered superior to monophonic sound. You can tell stereophonic sound, because different sounds originate from either speaker. This type of sound gives one the sense of being there during the recording. The best example of this is listening to a recording of the symphony, where different band members are located in different parts of the room. The strings are over here, and the horns are over there.

Surround sound was first pioneered by Dolby in the early 1970’s, and first used in movies such as “Tommy” and “Close Encounters of the Third Kind”. The Dolby process encapsulates four channels of audio; left, right, rear, and phantom center. The reason it is called phantom center is because it is essentially a mix of the left and right front channels. This gives the listener the impression of being surrounded by sound, hence the name surround sound.

Dolby surround sound has evolved considerably in recent years. Dolby 5.1 is bar far the most common. Dolby 5.1 is similar to traditional surround sound, but it is further broken down and processed into more distinct channels. Dolby 5.1 increases the range of sound by adding stereo rear sound as well as a dedicated subwoofer channel. This results in a far superior surround sound experience. You not only hear surround sound, but you feel it, too!

Technology is ever changing, and the marketplace offers many surround sound options. This article is not complete by any means, and only serves as a primer on the basics. Check out your local electronics superstore for the latest technology.

Impress your Friends with your new Home Theater System

2007-10-13T00:17:00.001-07:00

So you’re in the market for a new home theater system? Why not? Everyone you know either has one or wants one. Are you sick of having to go to your buddy’s place to watch the game on the big screen? Have you been playing that SNES system, circa 1995, since, well, 1995? Is your prized movie collection in laserdisc format? Maybe it is time to invest in a new home theater.

The first thing you ought to do is establish a budget. You could spend thousands of dollars on your new system, so give some consideration to what you are able to spend. There’s no point spending your rent money on a TV, if you will not have an apartment to watch it in.

Once you have decided what you are able to spend, draft a wish list of components you would like. Big screen TV or LCD projector? X-Box or Playstation? What about surround sound? 5:1? 6:1? 7:1? There are so many options, and the possibilities are seemingly endless. Keep it simple. Do you really need a 51 inch HDTV, for your 10x10 living room?

Either way, your system will definitely need certain components to qualify as a home theater. For the sake of being modest, why not consider getting started with a home-theater-in-a-box? These packages generally come with a surround sound receiver, a set of speakers, and a DVD/CD player. These systems are relatively inexpensive, and will leave you with enough cash flow to buy that new Sopranos box set! Capice?

A lot of people like to include gaming systems in their home theater, especially if they are able to play on a big screen. There’s nothing like playing Halo in life size! If you do most of your gaming on your computer, most decent video cards will have a video line out that you can use to connect to your TV or projector. Otherwise, you can incorporate any other console system into your home theater.

Your sound system will likely consist of a number of speakers (left, right, and center front, surround left and right, and a subwoofer). This is the standard surround system. The wattage of the amplifier you are using will greatly affect the sound being produced, so be sure to use one with enough power to effectively supply your system.

As I said, the options are seemingly endless for home theater systems. Be sure to buy from a reputable dealer, and do not buy anything that does not have a 30-day money back guarantee……just in case you have to return it to pay your rent!

Women Are Major Electronics Consumers

2007-10-13T00:14:00.000-07:00

Women are taking a greater interest in, and have a more sophisticated understanding of electronics than ever before.
Women actually spent more on technology last year than men, according to the Consumer Electronics Association. It says women accounted for $55 billion of the $96 billion spent on electronics gear (statistic from a January 6 CEA press release).
Women are increasingly interested in gadgets, from DVD players to digital cameras, for themselves or birthday gifts for their families.
Almost a third of women consider themselves early adopters willing to buy cutting-edge consumer technology.
CEA reported that women in the United States are becoming more likely to use consumer electronics. CEA's study provides detailed information about the attitudes, purchase considerations, decision influences, purchase channels, current product ownership, and future purchase intent. Here are some of the findings:
• Women are involved in 89 percent of all consumer electronics purchase decisions.
• 84% of women believe that new technologies can improve their lives.
• 48% of women age 18–34 own a digital camera.
The CEA survey noted that women have very positive reactions to specific technology areas, like HDTV, cell phones, and digital photography.
Women have more buying power and they increasingly use technology to manage their busy schedules. Women's comfort level with technology is at an all-time high.
Women want products that make it easy to connect and make it easy to operate; limited wiring or no wires at all; slim, well-designed products; making electronics available in different colors is not very important; low on setup and high on usability. Usability often is an important factor to women when they buy technology;
At CES, organizers hung big pink banners saying "Technology is a Girl's Best Friend," even though the group's own research found a third of women surveyed don't like products with girlie colors.
Nearly three-quarters of women surveyed complained about being ignored or patronized by sales people when shopping for electronics.
A growing number of companies are starting to target their wares toward female buyers.
Sony is outfitting its electronics with features that many women seek and is designing Sony Style retail stores to appeal to women’s preferences by creating an environment where women feel comfortable. Many of Sony’s efforts are focused on functionality. Women are becoming informed and involved in technology areas where they once had little or no presence.

Home Theatre - What Difference Do Cables Make?

2007-10-13T00:13:00.000-07:00

If you go to your local home theater store, you may be confronted by a variety of “extreme” sounding names for cabling: Mega Cables, Monster Cables, Uber Cables… the proliferation of “boutique” cabling is always a source of controversy in home theater and audiophile circles. The question is, how much difference do they make, and are they worth it? Well despite the perils involved in even mentioning this topic, I’m going to attempt to add something to the discussion.

The most important thing to recognize is that a cable cannot improve the sound of a home stereo system any more than an electrical wire can create extra electricity when you plug it into the wall. That’s actually a very good example, because when you’re listening to audio for instance, what we’re hearing is an electronic representation of acoustic sounds – that is to say, the actual sounds have not been captured and stuffed into a compact disc like fireflies in a child’s jar – they have been copied, imitated, and a representation stored on the disc as a series of numbers.

These numbers are then read and translated into electronic signals, which are sent to the speakers in order to approximate the actual sounds. With that in mind, it makes sense that poor quality wires don’t physically change the sound – instead it’s like a game of ‘telephone’, in which the band tells the CD, the CD tells the player, the player tells the wires, and the wires tell the speakers, with something being lost at every step so that the message “Aunt Betty baked a pie” is altered to “Fat Eddy wants to cry” or what should be a great live recording sounds tinny, distant, or otherwise just plain wrong.

A good cable will change the signal as little as possible, but all cables do damage your signal a bit – it’s simply a matter of degree. As far as which cables are the best? That’s up to you or your local audio guru to decide – much is up to personal preference, with the rest probably being left up to your budget to decide.

Consumer Electronics

2007-10-13T00:12:00.000-07:00

Introduction:

The daily use of electronic equipments are known as consumer electronics and includes TV, telephone, DVD, CD, PC, laptop etc. These equipments are manufactured throughout the world. With the advancement in electronic engineering at a continuous pace, a number of new variety electronics items flood into the market every year and the cost the existing products reduces continuously and it is one of the biggest advantage of consumer electronics industry.

Electronic waste is one of the problems associated with these electronic item and many manufacturers are now planning to deal with these waste.

Semiconductor:

All electronic devices use semiconductors and without these semiconductors none of the electronic device is complete. Semiconductor behaves like an insulator at absolute zero (-273 degree centigrade) and can be distinguished from conductor that at this temperature the outermost filled electron energy band is completely filled in a semiconductor compare to the conductor in which the band is partially filled.

At room temperature semiconductor show a very small electrical conductivity much lower than that of conductor.

Doping in semiconductor:

Most common semiconductors used for electronic devices are silicon and germanium. Although some other conductors such as iridium phosphide, gallium arsenide and mercury cadmium telluride are also used.

A pure semiconductor also known as intrinsic semiconductor, when doped with electron rich element e.g. arsenic or electron deficient element e.g. boron in very small quantity, its conductivity increases and the resultant conductor is known as extrinsic conductor. My doping arsenic (electron rich) and boron (electron deficient) in silicon, we get n-type (negative type) and p-type (positive type) semiconductor devices.

We may create a p-n junction by doping different element in different region of semiconductor and the device is known as diode. Similarly we can create p-n-p or n-p-n junctions and the device is known as triodes.

Electronic Devices

(a) Television:
It is a device by which we can receive moving pictures and sounds over a distance. The whole transmission and receiver systems require the following inputs.
1.Camera for live images or flying spot scanner for transmission of films and sound source.

2.Transmitters for transmitting both images and sounds.

3.Receiver systems for receiving these signals.

4.Display device, which is either CRT, Rear projection, LCD or plasma. To display the signal in the forms of images and sounds.

(b) Telephone:

It is the device for communicating by which two persons can send and receive sound signals over a distance. The system requires the following inputs.

1.The telephone equipment, which converts sound signals to electrical signals and electrical signals to sound signals.

2.Central exchange from where the subscribers are interconnected.

3.Wiring for connecting all the subscribers.

(c) Calculators:

It is a device used for carry out various mathematical calculations. The input required for calculator are as given below.

1.Power source (battery or solar panel).

2.Display device (LED or LCD)

3.Keypad containing all functions and numbers.

4.All electronic circuit devices.

Electronic Waste:

These are the waste electronic devices and if properly utilized may be valuable secondary raw material source for various electronic equipments and if thrown out may act as toxic due to presence of various toxic materials including lead, mercury, cadmium, arsenic etc. uncontrolled burning of these materials may also cause environmental problems.

Electronic waste is sometimes illegally sent to other countries for processing. However, due to complexity and difficulties in recycling, e-waste will remain an issue for the coming days.

MP3 Players – Many Capable Underdogs vs. the 800-lb. Gorilla

2007-10-13T00:11:00.000-07:00

Anyone lover of gadgets and portable electronics knows what an Ipod is – and in fact, many people who have no interest in personal electronics know exactly what they are. With over 21 million units shipped, and over 75 per cent of the personal Digital Audio Player (DAP) market worldwide, it’s no surprise – Apple Computer Inc. has become the 800-lb. gorilla of portable music players.

What most people don’t know is the variety of alternatives to the Ipod – devices which can play music, videos, and more, and which accept Secure Digital (SD) cards, Compact Flash, and Memory Sticks, and replaceable (or rechargeable) AAA batteries, often for a lower price than a comparable Ipod. The iRiver devices offered by South Korean manufacturer Reigncom range from small players intended to hang on a keychain or as wearable jewelry style devices to full-fledged hard-drive based units pointed squarely at the Ipod’s market.

SanDisk (a maker of Secure Digital flash memory) offers the Sansa series of MP3 players, with the distinction of being able to accept the same SD cards as many digital cameras, offering additional storage options and the flexibility to swap music collections without long transfer times. Some of Samsung’s YP series of MP3 players offer a miniscule size, picture viewer and LCD monitor, all at a lower price than many competing units.

Although there are a variety of choices, one major reason for the Ipod’s dominance is the sheer irresistibility of its marketing. The unit is sleek and simple, stylized yet understated, much like the rest of Apple’s product offerings. For many Ipod owners, the device is a fashion accessory as much as a technological device – when walking down the street, the trademark white earbuds are clearly visible even from some distance.

So visible in fact that they have become an easy target for some muggers – but many Ipod owners would sooner risk robbery than trade in their favorite fusion of fashion accessory and music player. Many people find that a particular device simply suits their tastes better than all the rest, but in many cases, one device isn’t necessarily “better” than all of the others, only different and with more or fewer features. The selection of manufacturers and models presently available offers as wealth of choices for any portable audio lover, whether replacing an existing device or entering the world of digital audio for the first time.

2007-10-13T00:09:00.002-07:00

When it’s time to find that special gift for a loved one or the birthday boy, do you head out to the shops in the hopes of stumbling across the perfect little electronic gadget? Even if you use the advertising circulars as a guide, that can often lead to a frustrating treasure hunt that burns you out while wasting your time and your money – and sends you home with a gift that’s not quite what you wanted in the first place. You’d think there’d be a better way. Well – there is. Whether you’re shopping for a cheap computer, an MP3 player, a digital TV or even a DVD movie, the smartest place to shop is sitting right in front of your computer.

It shouldn’t come as any surprise that it’s easy to find bargains on electronics online. Electronics and cheap computer parts and accessories were among the first merchandise to be sold regularly in online marketplaces and they continue to be the most popular type of items bought at online stores. The popularity of online shopping continues to grow, with total sales reaching into the tens of billions.

The Best Of Royal Paper Shredders

2007-10-12T01:08:00.000-07:00

Royal paper shredders are a market standard. The company which makes them, Royal Consumer Information Products, is descended from the Royal Typewriter Company, which was founded in 1906. Their line has expanded to include cash registers, faxes, shredders, postal scales, weather stations, imaging supplies and electronic organizers.

One of Royal's great paper shredders, the Royal 15MX is a high end shredder, intended to be used by small offices. This machine can easily deal with credit cards, paper clips, staples, and even CDs or DVDs. It reduces paper to crosscut strips that are .125" by 1.5" in dimension.

This shredder is able to handle fifteen sheets at once, and its basket can accommodate up to eight gallons of shredded material before it needs to be emptied. This Royal paper shredder weighs in at forty pounds and offers a one year warranty.

Another shredder from Royal, the JS55, is a lower cost shredder meant for home use. It retails at around twenty dollars and is capable of shredding as much as five pages at once. This shredder creates quarter inch crosscut confetti, weigh five pounds, and offers a three gallon receptacle.

It can, however, only be shipped within the United States. This shredder offers a one year warranty, but has received poor reviews from some users due to its low capacity. This shredder should certainly only be used on an occasional basis for destroying papers, not on a daily basis.

If your home needs to shred more often, consider the Royal 85X, a system that retails for around sixty dollars. It can handle ten pages at once and reduces them to smaller pieces than the JS55.

It can deal with credit cards, staples, and other tough items, and also comes with a year's warranty on parts. The trash receptacle is pull out, and fourteen and a half liters – enough to handle most jobs. Be sure not to use this shredder heavily, however. The system can easily become over stressed.

Another home use Royal paper shredder is the 7 Sheet Cross Cut with CD Shred model. This shredder costs around sixty dollars and handles paperclips, staples, and CDs. It shreds to .156" by 1.625" and offers the usual one year warranty on parts. The trash receptacle holds up to four gallons. As this machine weighs fifteen pounds, shipping outside of the US is not available.

Royal's paper shredders meant for home use also include the forty dollar, fourteen pound 8 Sheet Cross Shredder. This machine features an indicator light when there's an error, but tends to run loudly.

One of Royal's older paper shredders, the HT700X features a .125" by 1.5" crosscut, deals with credit cards and staples, and offers a four gallon bin and one year warranty. This shredder weighs ten pounds, and like many others, can only be shipped inside the United States. However, most reviews are poor, so buyers may wish to purchase a newer model.

A small, low cost example of Royal shredders, the JS800 retails at twenty five dollars. It produces fairly large pieces; .25" strips - which could be a problem for people concerned about security. This seven pound model does offer a six gallon trash bin for those who don't like to empty their shredder often.

This machine is only intended to be used occasionally, and must cool down for four minutes after being used for two. Despite this, it gets good reviews from most consumers.

Another lower end machine, the Royal 7 sheet crosscut paper shredder weighs in at fourteen pounds and costs forty dollars. It must also be shipped in the US, or to an APO/FPO address.

It has a feature to turn itself off to avoid overheating, which is useful for those concerned about shredder longevity. However, if you're not familiar with this feature, it can be disconcerting. Some also feel that this shredder is overly top heavy.

Royal's 15 sheet Heavy Duty crosscut shredder can be a great deal. This machine normally runs around three hundred fifty dollars, but can be found online for a hundred and forty. It's a commercial shredder that produces eight inch by one inch confetti, and can handle fifteen pages at once.

This Royal paper shredder also features a slot specifically for destruction of CDs, DVDs and other data disks. The majority of people who buy this paper shredder are happy with their purchase.

Last but not least, Royal offers a 10 Sheet crosscut Paper Shredder, which is a well reviewed mid-level machine. At sixty dollars, it won't break the bank, but has the power to shred discs. This machine produces 1.375" by .16" confetti, can only be shipped within the United States, or to APO/FPO addresses.

Hdtv Is Redefining Television Viewing

2007-10-12T01:02:00.000-07:00

Increasingly, broadcasters and viewers alike are giving High-Definition TV high marks.

If you think you're ready to make the leap, here are a few points to keep in mind:

• Purchase an HDTV-ready or HDTV-capable television set. There are several kinds of HDTVs, such as rear-projection, plasma and LCD, but the two main distinctions you need to be aware of are HDTV-ready and HDTV-capable. HDTV-ready means that the television has an HDTV tuner built in that enables it to receive over-the-air high-definition signals from your local networks. HDTV-capable means that the television is able to receive HD signals, but only in conjunction with the use of an HDTV converter box from your cable or satellite provider.

• Get an HDTV converter box from your cable or satellite provider. Depending on your HDTV programming service provider, you may be able to lease one for $5-$10 a month. There are great deals and trial offers right now, so shop around.

• The channel you want to watch must be broadcast in high definition to see it in true HD. All the major broadcast networks (ABC, CBS, NBC, PBS and FOX) transmit at least some programming in HD. DIRECTV announced that it would have 100 HD channels on its service by year's end. Many cable networks are offering HD versions of their popular channels. For example, Discovery Communications recently launched HD simulcasts of Discovery Channel, Animal Planet, TLC and Science Channel. Besides your local broadcast networks, there are HD channels in just about every possible genre: news, sports, documentary, nature, science, movies, music, history, home improvement, cooking-even reality.

• HD versions of your favorite channels are often on a completely different end of your on-screen channel guide. The good news is that most HD channels are grouped together to make things a little less confusing.

Once you decide on an HD television set and have your HD converter box hooked up, you're ready to go.

With an HDTV set, you can watch spectacular HD shows like Discovery Channel's "Planet Earth."

Simple Ways To Do Refactoring With Prototype Building Materials

2007-10-12T01:01:00.001-07:00

Many years ago, people used to rely on Lotus 123 to get work on the computer. WordStar was the program of choice when preparing documents. Years later, Microsoft hit the market that was followed by other operating systems such as Linux and Macintosh.

Ever since Microsoft started in the 1990s, various improvements have been made and the latest edition to the family is Windows XP. Why the upgrades some may ask This is to satisfy the requirements of businesses and end users who are not satisfied with the current systems.

How does the company know that people are not satisfied When systems fail, a report is generated that is then sent to the corporate office. Software designers will then find answers to this problems and then release product updates or a new program to the public, which is what prototyping, is all about.

But there are many ways to create a new prototype. The most common, which is making a few alterations to the program, is what is called prototype refactoring. After all, computer codes are identified in numbers such as 1 or 0 and most users want he problem fixed rather than going out and buying a new one.

This case also applies for automobiles so a customer who had a problem for example with the automatic transmission system will go back to the dealer to have this repaired instead of buying a new car.

Software developers usually try to solve two contradictions in order for it to work. This is like hitting two birds with one stone so a lot can be achieved with less effort and here are a few ways how this is done. The first is by reviewing the HTML application that can be edited using Macromedia Dreamweaver. When the changes have been made, this can be saved and an update can be sent to the end user.

The second is by using MS Visio. This is better known as a drawing tool but those who are experts in making programs also use this to make alterations in the settings panel to make it work.

The last is by doing something with the worksheet compiler. Believe it or not, developers can make improvements by simply using tools such as Microsoft Word or Excel.

The three just mentioned proves that there are ways to conduct prototype refactoring without doing a major overhaul of the system. The fact is, the system works and the software developer has to fix a few glitches.

Rapid prototyping is the process used to generate three-dimensional models that do not require any machining or tooling. Instead, rapid prototyping makes use of cutting edge technology that allows a physical object to be formed by adding a material layer by layer until the desired shape is achieved. This additive process is being used instead of building prototypes by cutting away material through machining which is subtractive.

Rapid prototyping allows more flexibility than machining because the even complex model designs does not suffer any limitations during its production. Rapid prototyping enables engineers and product designers to generate three dimensional models quickly and accurately.

Different rapid prototyping systems make use of a variety of materials to create different three dimensional objects. A common material used is prototyping wax. This material is usually ideal when engineers and designers require small quantities of casting parts to create intricate patterns without the use of tooling.

Prototyping wax can also be used together with other types of prototyping materials in order to make the resulting prototype work better with different casting methods that make use of metals as well as non-metals. Combining prototyping wax with other materials to create the models will also be ideal for low-temperature furnaces and vacuum plaster casting methods.

A rapid prototyping modeling process utilizing prototyping wax to create a wax pattern can be advantageous in some ways. Forming and de-waxing a shell mold made from prototyping wax can be done quite rapidly using normal casting procedures. Using this type material simplifies in a way the model-making process that helps you to get your products to be developed and be released in the market faster.

Aside from prototyping waxes, there are also other materials being used for a number of rapid prototyping processes. One such material is thermoplastics. If product engineers are looking forward in creating durable prototype parts that might require aggressive functional testing, thermoplastics can be the ideal material to use for rapid prototyping. Thermoplastic materials have effective heat and chemical resisting properties that make them the best choice for models that undergo aggressive product testing procedures.

Not only that, thermoplastics also provide excellent surface finish to prototype models. They are also machinable and weldable when required. Thermoplastics can also be joined mechanically or with the use of special adhesives. Other prototyping material choices available include powdered metals for injection molding, and for directly creating metal prototype parts, Polycarbonate and polyphenylsulfone materials for forming durable, high-strength, and functional prototypes that are to be used for testing and final design verification.

The Basic Features Of A Spectrum Analyzer

2007-10-12T00:58:00.000-07:00

A spectrum analyzer is a device that measures the power spectrum. It is often used to examine the components of a waveform, whether it is electrical, acoustic or optical in form. There are basically two kinds of spectrum analyzers, the analog and the digital.

It also displays the received signal and compares the bandwidth to the frequency. A comparison is often done with an Oscilloscope, which compares the strength of the signal against the time.

Spectrum analyzers are also useful in analyzing amplitude against the frequency. Amplitude is normally measured in power or in dBm instead of volts, which is what is normally used in most spectrum analyzer.

The reason behind this is the fact that there are low signal strengths and frequency of movements that may not be measured. Spectrum Analyzers can only measure the frequency of the response at powers as low as 100 dBm. These are the levels that are frequently seen in microwave receivers. Oscilloscopes, on the other hand, cannot measure such very low voltage. The device can only deal with very low frequency levels and high amplitude.

The analog analyzer uses a filter with a mid-frequency that can be automatically shifted through a series of frequencies where the spectrum will be measured. The digital spectrum, on the other hand, utilizes a mathematical process called the Fast Fourier Transform (FFT), which is used to transform a wavform into the different components of its frequency spectrum. This way, computer programs who do the transformations will make the audio processing much easier. FFTs, however, are not only used for this purpose. They also have applications in other fields.

There are also spectrum analyzers that makes use of a technique wherein the incoming signal is converted into a lower frequency. This hybrid technique uses first the superheterodyne and then the FFT techniques. Examples of spectrum analyzers with this technique are those made by the Tektronix from the real-time spectrum analyzer series.

Spectrum Analyzers have so many applications. One application is the device frequency response measurement, which refers to the amplitude response of a machine against frequency of device.

Another application is Microwave Tower Monitoring, which measures the transmitted power of the machine as well as the power that it receives. This is utilized for the verification if the signal strengths and frequency of the transmitter. A directional coupler is used to tap the power. This is done so as not to disturb or interrupt communications.

A spectrum analyzer is one instrument that is often used in the conversion of higher frequencies, often those that range up to 10s gigahertz. It is a sensitive receiver that works based on the super-heterodyne receiver principles.

Once received by the spectrum analyzer, the frequency signal is swept through a pre-selected set of frequencies. The selected frequency is then converted into a DC level, a logarithmic scale, that can be measured. It is also displayed on the CRT, where the y-axis contains the signal strength while the frequency is seen on the x-axis.

Spectrum analyzers, however, cannot detect signals that are too weak or weaker than the noise in the background. This is the reason why the spectrum analyzer is often used in tandem with an RBW. In fact, RBW is one of the vital considerations in choosing or buying a spectrum analyzer.

Here, the received signal strength is measured in dBm or what is called decibels, the zero of which corresponds to 1mWatt on the logarithm scale. The reason for the use of power or decibels instead of the usual voltage is the fact that what is being measured are the low signal strengths and the frequency range of measurement.

Spectrum analyzers can only measure the response of a device powered at 120 dBm. These are the power levels that are normally seen in microwave receivers.In addition to the RBW, there are other key features of spectrum analyzers that people need to consider before buying one. One of these vital components is the resolution width, which affects the sensitivity of the spectrum analyzer. In fact, the sensitivity is directly dependent on this feature. For instance, if the measurements are the over a wide band, a 3 KHz RBW will normally be effective.

However, if you need to analyze a much narrower spectrum, such as with filters, then you may need a bandwidth resolution of 300Hz or a 10 Hz RBW. All depends on how the spectrum analyzer will be used. Another feature is the frequency range, which refers to the frequencies that you will be needing in order to take measurements. Spectrum analyzers have ranges from 100 Hz to 50.

Another is the frequency stability, which allows the spectrum to maintain its frequency within a specific levels that is precise and accurate. Often, the frequency stability is entirely dependent on the stability of the oscillator. A provision for Narrow band measurements for instance is an important parameter because spectrum analyzers do not usually have very high stability clocks.

Plasma HDTV

2007-10-12T00:45:00.000-07:00

Change the way you used to watch the television with the new TV on the block that has made the conventional analog television sets run for their survival. We are talking about a plasma HDTV. Its a new technology that has altogether changed the whole scenario. The High Definition Plasma Television is here, that is what popularly known as Plasma HDTV, that has given a new dimension to the TV watching experience. But, is the technology worth of receiving so much of praise. In this case you have to see it to believe it. As the name itself reflects, the HDTV is a high definition TV that changes the picture quality by bringing more life to it and thus has many advantages over the conventional analog TV set.

Lets talk about what you get when you go in for the Plasma HDTV.

Much Higher resolution: this is where the Plasma HDTV can beat any competition coming its way. Compared to the conventional TV sets, the Plasma display devices have much higher resolution, and are capable of displaying full HDTV and DTV signals as well as XGA, SVGA and VGA signals from a computer.

Elimination of scan lines: Contrary to the Plasma TV the conventional TV monitors use an electron beam to scan the picture tube at regular intervals that may produce the scan lines, in a standard NTSC TV. Plasma displays in this case, include built-in line doubling to improve image quality when switched to standard analog video sources such as TV broadcasts and VCR tapes.

Exceptional color accuracy: Another great advantage is the exceptional color accuracy that is achieved through displaying 16.77 million colors that can bring any picture to life.

Wide-screen aspect ratio: To bring back the experience of watching films in theatre, Plasma display devices have a wide-screen 16:9 aspect ratio, that allows the DVD-Video movies to be viewed in wide-screen format.

Perfect flat screen: is another biggest advantage with Plasma screens. This helps to eliminate the edge distortion that can occur in normal displays.

Uniform screen brightness: the realism can be achieved with this factor that also helps in soothing the eyes with the plasma displays illuminating every pixels evenly across the screen.

Slim space-saving design: a few inches thin, hag it on any wall you like and it gives you the installation options as never before. Dont bother about the standalone way if you dont want to keep it like that. The best part is the can match your dcor, and actually increase the style statement of your home.

Wide viewing angles: of 160 degrees allows a larger number of viewers to enjoy perfect image reproduction irrespective of their position in the room.

Universal display capability: makes them include and play a wide video formats. Most of the plasma HDTV ware compatible with composite video (NTSC, PAL SECAM) (standard RCA jacks), S-video and component video inputs, plus one or more RGB inputs to accept the video output from a computer.

Resistance to magnetic fields: as they do not use the electron beams like the conventional TV sets, they are unfazed by the effects of magnetic fields. That is why it can be placed in a close proximity to any device that produces magnetic fields, for instance, speakers.

Stereo Speakers: Pair Down the Choices

2007-10-11T05:10:00.000-07:00

Stereo speakers come in pairs, and they are for people who really enjoy a great audio experience. Today's marketplace is flooded with surround sound speaker systems, but there are still plenty of great choices for traditional stereo speakers. The combination of quality and affordability is more prevalent than ever before, so whatever your price range and sonic requirements, good options are abound.

The advent of internet-direct sales is bringing numerous high-quality products to the marketplace at bargain prices. Without the overhead costs associated with traditional brick-and-mortar stores and marketing, these companies offer incredible speaker values. In addition to the internet, mass retailers as well as mom-and-pop stores also have familiar brands in all price ranges. Here are some of our favorite new stereo speakers.

Axiom M3

Axiom prices its M3 speakers at about $330 per pair, and this is a steal. These large bookshelf models use a two-way, rear-port design with 6-1/2-inch drivers, and they work best on open bookshelves or speaker stands. The unique wedge-shape cabinet suppresses internal resonance that can negatively color the sound, and it also makes for a unique look. The M3 speakers are available in black oak, Boston cherry, Mansfield beech and light maple finishes.

This is a fantastic all-around bookshelf speaker that sounds great on it's own for music, but it can also be used in a matched surround system with a subwoofer for incredible home theater performance. Reasonably priced, the Axiom M3 represents great value in a versatile bookshelf speaker.

Axiom M3 speakers

Jamo C 803

At around $900 per pair, the Jamo C 803's are some of the most expensive bookshelf speakers we have tested. They are also our favorites and are worth every penny. The C 803 is a large, rear-port, two-way speaker with a 7-inch woofer and 1-inch dome tweeter. The cabinet is gorgeous, with a sculpted and curvy shape that will garner attention from your guests. It is available in a black ash or dark apple finish.

This is a very high-quality speaker with excellent build quality, and it produced a very musical tone. When placed on stands in our listening room, the C 803's sounded better than many floorstanding tower speakers we have auditioned. They had a wide soundstage and reproduced music with astonishing detail and clarity. If your budget allows, the Jamo C 803 represents one of the best choices among bookshelf stereo speakers.

Polk Audio Monitor 60

Polk Audio's Monitor 60 tower speakers deliver solid stereo performance and would serve as a respectable foundation for a home theater system. Polk has a history of producing affordable, high-performance speakers, and the Monitor 60 continues that tradition with aplomb.

At about $650 for the pair, the floorstanding Monitor 60 speakers represent a great value. Each tall, slender speaker boasts three 5-1/4-inch drivers and a 1-inch dome tweeter, delivering powerful sound for both music and movies. Sonically they were full and rich, with a detailed soundstage that we would have expected from speakers costing hundreds more. If you are looking for full-size towers that will live up to Polk Audio's sterling reputation, check out the Monitor 60.

Polk Audio Monitor 60 speakers

AV123 x-ls

The AV123 x-ls is a large bookshelf speaker offered exclusively online at www.av123.com. This high-quality speaker has an entry-level suggested price of about $220 per pair, but it performs like a much more expensive model. The x-ls has a two-way, rear-port design with 6-1/2-inch drivers. Each cabinet is very heavy, relatively speaking, but that is a result of the quality construction. The exterior is offered in a satin black or white shadow maple (additional finishes will be available later in 2007), both of which are furniture-grade finishes that rival that of the most expensive speakers out there.

Although suitable for seating on open bookshelves, we achieved the best results from the x-ls speakers by placing them on 23-inch stands. They exhibited a fantastic soundstage no matter what genre of music we played. In fact, the x-ls performed better than speakers we have tested costing twice the price. The AV123 x-ls speakers are a fantastic value.

Pioneer Pure Malt (S-A4SPT-PM)

For a truly unique set of small speakers, Pioneer's Pure Malt bookshelf speakers are just the ticket. The Pure Malts are handcrafted from retired 50-year-old oak whiskey barrels, which are flattened and dried, then cut and assembled into speaker cabinets. The resulting finish has a beautiful and luxurious aged-oak look.

The Pure Malt speakers have 4-inch drivers, but they produced a remarkably full sound that could easily fill a small room or office. The aged hardwood contributed to a rich, mellow tone that was quite enjoyable at moderate volume levels, whether we were listening to pop, jazz, classical or acoustic music. Craftsmanship comes at price, and with a suggested price of $299 each (available only at www.pioneerelectronics.com), you should think of the Pioneer Pure Malts as both speakers and art.

Car Speaker Buying Guide

2007-10-11T05:09:00.000-07:00

The Basics: Car Speakers

Upgrading the speakers in your car is perhaps the easiest and most popular mobile entertainment improvement possible. Due to the popularity of this upgrade, you'll find more choices than any of the other categories. Just walk into any car audio specialist and you'll see the vast array of options. The speakers that come in most cars are usually not quite top of the line, although many automobile manufacturers have recognized the importance of good speaker design, so they are using some really good components as an incentive for the entire automobile purchase.

Subwoofers are the most immediately evident improvement one could make to an automobile's sound system. The speakers that most manufacturers install in their cars are too small to properly and accurately produce low bass frequencies. In this case, size does matter. Speaker size does dictate the volume and ranges of frequencies it will be able to produce. However, a driver that is too large might take too long to react to the demands of music--they don't have an accurate transient response.

Subwoofers are available in two forms--raw and enclosed. An enclosed subwoofer consists of a driver mounted in a box, or it can refer to a band-pass box. A raw subwoofer is just the driver--a speaker cone suspended in a "spider," the metal frame that holds the speaker. The motor consists of the voice-coil and magnet. Enclosed subwoofers are typically unpowered, so you'll need a channel of amplification. However, there are some enclosed systems that include an amplifier specifically designed for the subwoofer component, which takes a lot of guesswork out of the equation.

How to Shop

"Drop-ins" are designed to fit exactly in the cutout spaces used by the factory speakers. This eliminates the need to alter the interior of your car in any way (ideal for a leased vehicle) and installers can usually incorporate the existing speaker grilles for a truly stealthy look. This is probably the easiest option for do-it-yourselfers. Simply remove the speaker grille, unscrew and remove the original speaker, disconnect the speaker wires, and connect and attach the new speaker. If you're planning on a more intrusive upgrade, most cars have additional speaker cutouts (for upgraded factory systems) hidden in a variety of locations throughout the interior frame. Any good installer will know where they all are. Many audio manufacturers design speakers in a variety of shapes and sizes to fit a variety of factory cutouts. Some retailers have a detailed listing of what speakers can be placed in what cars using cutouts or to use as drop-ins.

Once you've determined where you want speakers, you'll need to determine what kind to get. Replacement speakers come in two basic designs: coaxial or component. A coaxial speaker has the tweeter suspended over the woofer. A typically more expensive component speaker system consists of a separate woofer and a tweeter that can be positioned for a more accurate high-end response and a wider stereo image. They usually come with the necessary crossover electronics. Although usually considered a separate upgrade, you can also add a subwoofer.

Depending on what other components you are using, you should look at the sensitivity rating of the speakers. This indicates how efficiently the speaker handles the power that is supplied by your amplifier or head unit. Also called an efficiency rating, the higher the number, the louder your speakers can play given the same amount of amplification.

Car Signal Processor Buying Guide

2007-10-11T05:08:00.002-07:00

The Basics: Car Signal Processors

Signal processors, or digital signal processors (DSPs), are the final stage in fine-tuning the sound in your automobile. The term covers a variety of components--by definition, digitally affecting the sound to alter it from the input signal. Signal processors can refer to an equalizer/crossover unit, a surround sound decoder, speaker steering (allowing you to turn on and/or off specific speakers) and delays for the speakers, sometimes referred to as digital time alignment.

An add-on equalizer might be just what you need to finally make your car audio system live up to its full potential. An equalizer lets you finely adjust the sound that gets fed to your speakers, allowing you to compensate for deficiencies in the frequency response of a speaker or an audible shortcoming in a component. Equalization also lets you attempt to control a car interior's typically troublesome acoustics. In very basic terms, equalization boosts or cuts certain ranges of frequencies from an audio signal--a very sophisticated tone control, with more than just bass and treble adjustments.

Stand-alone crossover units remain in the realm of high-end audio gear. While a few amplifiers do some sort of crossover-type frequency division, there are times when an audiophile wants and needs an external crossover unit. It's easy to see why--an external crossover unit usually offers the ability to fine-tune adjustments in a way no amplifier or head unit can.

How to Shop

Your reasons for purchasing a signal processor really determine what features you should look for. As most cars already have the amplification needed for four channels of speakers, some signal processors include amplification for the additional center channel and subwoofer that are required to reproduce 5.1 Dolby Digital and DTS surround sound. In addition to these set formats, some signal processors will add an artificial surround sound field to a regular stereo signal. These make the music sound like it's being played in a stadium, jazz club, or whatever the engineers decide to call their programs. These come as prenamed presets, however, you might want to take control and program your own personal sound fields and store them in user presets. Some processors have a wonderfully useful feature that compresses the audio signal. By reducing the overall dynamic range, the softer passages of music aren't lost under engine noise, and the loud peaks won't blow out your speakers.

A feature that is found on some higher-end processors is an independent equalizer for the left and right speakers. This feature helps to compensate for the sometimes non-ideal placement of speakers that are found in many vehicles. Digital time alignment also compensates for the placement of speakers, since you will rarely find yourself sitting in the perfect sweet spot evenly placed between all four speakers. This works more effectively than just using volume to control the balance of the speakers. Time alignment uses digital delays; psychoacoustics to fool the ear into thinking the speakers are centered on the drivers seat.

Car Amplifier Buying Guide

2007-10-11T05:08:00.001-07:00

The Basics: Car Amplifiers

Sometimes, you just need to crank up the volume. Car audio systems must overcome a good deal of ambient noise--a vehicle traveling down the highway in the company of other loud engines is surrounded by a high background noise level. Factory-installed head units have a modest amount of amplification (generally about 10 watts per channel or less), and many aftermarket head units have at least twice that. The more power the amp included with your CD or cassette player delivers, the cleaner the sound from the speakers. But be careful--a receiver rated at 50 watts maximum power probably has no more than 20 watts of clean power. For that reason, serious mobile listeners eschew the modest amplifiers built into head units and instead opt for powerful external amplifiers.

How to Shop

For the easiest and typically least expensive installation, look for a single amplifier to power all the speakers in a car system. This would be the number of channels listed on the amp, as a single channel is only capable of powering one speaker. Moreover, look for an amplifier that contains its own crossovers; these circuits split the music frequencies so (for example) the highs go to the front speakers while the lows go the rear speakers. This helps maximize power delivery to the speakers and improve sound. When shopping, look at the way an amplifier lets you control these crossovers. Some use rotary controls, while others have less accessible inset controls requiring a screwdriver for adjustment.

You could consider amplifiers with one, two, or four channels, but you'll need a channel for each speaker; this soon increases the complexity and cost of the system. Also, if you'll be adding a subwoofer for killer low-ends sound, you'll usually need a separate amplifier. Remember, every speaker will use one channel of amplification. Four-channel amps are, by far, the most popular.

Amplifiers don't really come with a massive array of features, but there are a few to consider. Soft-start circuitry eliminates the thumps and thuds that can be annoying and potentially damaging to car speakers. Depending on your application, the number of speaker-level and line-level outputs and inputs need to be considered. Make sure you have enough for the setup you are currently installing, while leaving room for at least one future upgrade.

Amps generate a significant amount of heat that affects their efficiency. Numerous methods of dissipating this heat are used--everything from metal fins that create more surface area for air cooling to a few systems that actually use liquid coolant to keep the temperature down. Read reviews and specs to choose between hype and facts.

Car Alarm Buying Guide

2007-10-11T05:07:00.000-07:00

The Basics: Car Alarms

While most purchases from the local car electronics shop are purely for entertainment, an alarm's sole purpose is to protect your investment, not only in your automobile and your mobile electronics, but in your personal safety as well. Other safety and security items include remote starters and backup sensors.

Alarms have come a long way from the systems that merely sounded when a door was opened improperly. They now flash the vehicle's lights, disconnect the ignition, and act as keyless car entry systems. Some can even use a computer interface to completely customize their performance. Alarms use a combination of techniques, the most common being motion sensors and dome light detectors. When a door opens, the overhead light comes on, triggering the alarm. Many of today's security systems provide multizone protection, which lets you decide what you want the alarm to protect and selectively arm and disarm individual components.

Most remote starters can start a car from 500 feet away or more, and if you've set your climate controls before you got out the last time, your car will be just right when you're ready to go. While comfort is one advantage, this is also a way to preserve other components--people with a short commute know that mufflers need a certain amount of drive time to blow out accumulated moisture. The extra warm-up time might cut down on the frequency of muffler replacements.

Some car owners feel every scratch and ding on their vehicles as though the damage was done to their own bodies, and accidents they cause themselves are even more painful. People back into things every day, including light poles, garage walls, garbage pails, stray toys and bicycles, shopping carts, and other cars. In addition, the size and design of vehicles these days (think SUVs) make reversing more challenging. While these minor accidents are unfortunate and annoying, incidents involving children are immensely more serious. All of these accidents might be avoided with the aid of backup sensors.

A backup sensor transmits an ultrasonic signal from its mounting position on the back of a car. If the signal encounters an object, it bounces back to a receiver, which can then determine the distance between the transmitter and said object. This works along the same principles as radar; the length of time between the signal's emission and reception determines the distance. The ultrasonic pulses work through all kinds of low-visibility situations, and they are also helpful in the blind spot. Many new systems now combine sensors with a small video camera to really let drivers see what's going on behind them, while others rely solely on a camera and a dashboard-mounted video screen. With the rapid increase in popularity of in-vehicle DVD systems and displays, some manufacturers are now offering cameras specifically designed to work with car audio/video systems.

In no way do these systems replace common sense. They do not offer 100-percent coverage, especially at extremely close range. Always proceed with caution.

How to Shop

Security systems come with a wide range of features. An essential option is a panic alarm, which sets off the alarm via a button on the keyless remote. Dual remotes are handy for cars that generally have more than one driver. Some systems add a safety feature that will turn on the interior car lights when the system is disarmed, allowing for safe entry. A field-disturbance sensor sounds with any movement inside the car, and a back-up battery keeps the system armed even if the car battery dies or is disconnected.

Remote starters are operated from a small controller that is designed to fit on a key chain--most systems come with two remotes to accommodate two drivers of the same vehicle. They can work on their own, but remote starters work more securely and efficiently when used in conjunction with a car alarm system. Not only can they be programmed to start the engine, but also they'll perform basic functions like unlocking a door or opening the trunk with the touch of a button. Check to see that the package you're looking at will work on the type of car you have--automatic transmissions, keyless entry doors, and fuel injected systems are sometimes required. Also, some systems will not work with diesel engines.

You want to look for a backup system that includes all of the required wiring cables and harnesses, and make sure you're comfortable with the installation. Some backup systems can be easily installed at home, but others require professional installation.

Boom Box Buying Guide

2007-10-11T05:04:00.000-07:00

The Basics: Boom Boxes

Boom boxes have become a generic term for any portable audio device with speakers. The word started out as a description of the basic sound they all made--plenty of muddy "boom" to fill a room with no high-end clarity. Technology has improved the sound quality, but the name remains the same.

Boom boxes are commonly confused with minisystems. However, minisystems don't have carrying handles and they only run on AC power, where as boom boxes usually do. And although they can run off an AC power supply like minisystems, boom boxes are given away by their battery compartment.

How to Shop

If you've already started looking at boom boxes in the stores or online, you'll immediately be struck by the enormous variety of styles available. When they first became popular, all boomers looked alike: rectangular boxes with two forward-facing speakers on either end, cassette decks on the front, controls on the top, and of course, the handle.

What has really changed the most in the boom box industry is the choice of features. Every combination of formats is available. Your choice of a boom box should begin by determining what's important to you. Most players have the basics, such as an AM/FM tuner, a cassette player, two speakers, and a CD player. Then, the options take over. The radio can have a digital tuner, which makes preset selection easier. The cassette player can be a dual transport (double deck) that allows for hours of continuous playback or dubbing from one deck to the other. A number of newer units omit the cassette decks entirely.

CD players and CD changers are generally standard issue on boom boxes. A single player, three-disc changer, and even a five-disc changer are options. A changer can use separate disc drawers or use a carousel to store discs. Which one you choose is entirely up to your personal preferences, but separate drawers have always seemed more convenient.

Programmability of track order, track repeat, and random playback are features that add to the usefulness of a boom box. Another feature of interest is a synchronous start that coordinates between the CD player and cassette to start recording. Playback of MP3 and other digital audio files is a relatively new feature in boom boxes, and this will no doubt become more common in the near future.

All features aside, the only thing that really matters are the speakers. Unfortunately, that's usually the worst part of boom box design. Recently, however, small speakers are being designed to output a fuller range of frequencies, and amplifiers are getting more efficient. Inexpensive boom boxes typically save money by skimping on speaker components and design. The best advice is simple: listen before you buy. Unlike other audio products that don't vary much in actual sound quality, boom boxes vary greatly.

The Secrets to Finding Quality Cameras and Lenses Online

2007-10-10T05:24:00.000-07:00

The best way to locate detailed descriptions of all the camera and lens options available is to shop for cameras online. Then you will be able to make your choices based on these descriptions. Whether you are an amateur or professional photographer, there are many places on the Web to look for the camera you want.

What Camera Do You Need?

First of all, you must decide what type of camera will meet your needs. You may only need a simple point and shoot for family photos. These cameras will be less expensive and uncomplicated to operate. You can get automatic actions such as zoom and flash or automatic advancement in 35mm cameras. They are usually compact and simple to use, which makes it easy for anyone to take pictures.

However, there are limitations with those cameras in the control of exposure and focusing. For someone who is more involved in amateur photography, added manual control may be beneficial. One of the biggest advantages is the ability to change lenses to get a better zoom picture. Sporting events and vacation photos will be more pleasing to look at when taken with the right types of lenses.

The serious and professional photographers will want the best cameras with the features that suit their needs. This would include manual focus to give the clearest and sharpest pictures. Also, there are several different size lenses to get a good picture from a greater distance.

Different Camera Styles

There are basically four different kinds of cameras to choose from. The first, usually cheapest and easiest to handle, is the point and shoot. The second is the 35mm SLR that allows more variety in lenses and focus. The third is the Medium Format, which is larger and gives a larger negative to work with. It is completely manual but supplies a high-quality photograph. The fourth is the Large Format camera used by the professionals. It is larger and harder to use but provides stunning photographs from the larger size prints.

Shop Online for Cameras and Lenses

When you have decided the type of camera you need, you are ready to shop online. To get started, you simply type in your key words on a search engine. Once you know what you are looking for the task will be much simpler. There are many sites that offer cameras at wholesale or discount prices. They usually offer all the well-known brands such as Leica, Minolta, Canon, Horizon, Contax, Olympus, Mamiya, Nikon, Hasselblad, Pentax, and Noblex.

Some sites sell used products that have been gently used or refurbished. Purchasing these cameras would save you some money and will usually still come with a warranty. There are sites with online catalogs where you can look for the brand or style you want. They also provide search features so you can shop by key word or brand name.

Compare Before Buying

It is a good idea to shop around and compare prices and shipping costs before buying a camera. Remember to include the shipping costs when calculating the total price of a camera or lenses. Don't buy a camera at a discount price just because it is a good deal. To be sure you are satisfied with your purchase, look for the key features and quality you want. Buy a camera based on your needs and you'll enjoy taking fabulous photographs with it for years to come!

Everything You Need to Know About Hidden Cameras and Other Security Cameras

2007-10-10T05:21:00.000-07:00

Business owners, law enforcement officers, and parents have found enormous value in hidden cameras over the past several years. Business owners often use surveillance systems to keep an eye on employees or their store to protect the business from theft or abuse. Hidden cameras are used by the police to catch criminals in the act or to record arrests as they occur. Parents use nanny cams to make sure their children are being properly treated. If you're thinking of buying a hidden camera or other type of security camera, here's a quick guide below.

How Hidden Cameras Work

There are two types of hidden cameras - wireless and wired. Wireless hidden cameras use batteries and have the camera and transmitter concealed with no visible wire from the camera to the recording equipment. Wired cameras will have a physical wire running from a VCR or PC to the camera.

To determine if you need a wireless or wired hidden camera, consider the length of time you will need to record. Will the batteries hold up long enough? The location of the hidden camera is also important. Hidden cameras come in a variety of shapes, forms and themes. Choose a camera that goes well with the environment around so it will be unnoticeable. Some cameras feature wide-angle viewing, which comes in handy when you need to survey a large area. Also, the lighting of the area is important. Check the hidden camera's resolution before buying.

Types of Hidden Cameras and Security Cameras

There are many types of hidden cameras and security cameras for all situations. From dummy cameras to professional cameras, each one serves its own unique purpose. Here are some types of cameras and their benefits.

Nanny Cams

Protect your children throughout the day with a nanny cam. Even if you have a nanny you feel you can trust, it doesn't hurt to have a nanny cam for the safety of your children and home. Nanny cams are actually hidden cameras that come in many shapes and sizes. The camera might be embedded in children's items such as teddy bears, backpacks, baby wipe containers, dolls, stuffed animals, etc. These items can be placed in the child's room along with other toys. There are also nanny cams for other rooms of the home, including clocks, radios, table lamps, food containers, thermostats, pillows, picture frames, hair dryers, DVD players, etc. Every room can have a nanny cam if needed. Check with your local law enforcement before getting a nanny cam or hidden camera for your home to be sure there are no restrictions.

Surveillance Systems

If you need more than a few hidden cameras, consider a surveillance system. Surveillance systems enable you to observe multiple locations through one sophisticated system. With a channel DVR system, hidden cameras are set up in different areas and interconnected so you can survey all the areas through multiple channels. You can expand your surveillance system as your business or operation grows. There are also portable DVR surveillance systems and those that enable you to monitor the area from any location online.

Monitors

Monitors are screens that show what is going on as it happens. Many public places have monitors set up to let people know they are being recorded. Some monitors are used by the owners or security guards to keep an eye on areas from behind the scenes.

Dummy Cameras

Dummy cameras are not hidden cameras or even real security cameras. They look like real security cameras and give an appearance that the area is being recorded. The thieves won't know if the camera is real or not. Dummy cameras are often used as a deterrent by many business owners.

Professional Cameras

Professional cameras are often used to survey large businesses or offices, inside or outside. They can be mounted on walls or ceiling brackets. Some are waterproof for outdoor surveillance. A variety of professional cameras are available for different situations.

Hidden cameras and security cameras are great for protecting your children, home, business or property. Use the guide above to find the hidden camera or security camera that's right for you.

Your Guide to Battery Types

2007-10-10T05:19:00.000-07:00

Every mobile electronic device we own runs on battery power, yet we take batteries for granted - at least until they run out of juice. No matter what kind of device battery - laptop battery, cell phone battery, camcorder battery, remote control battery - you need, it's helpful to know the various kinds of battery types and their uses.

Gel Battery - A gel battery is also known as a sealed lead acid (SLA) battery, and its distinguishing feature is that it doesn't have to be kept upright in order to work. An SLA battery continues to perform in extreme conditions, such as hot temperatures, or under vibration. SLA batteries are often used in wheelchairs, scooters, and uninterruptible power sources. It's best to keep an SLA battery charged, or to charge it more often than you would other types of batteries.

NiMH - NiMH stands for Nickel Metal Hydride and is the battery of choice for many cell phones, camcorders, digital cameras, GPS systems, PDAs, and other personal electronics. NiMH batteries are also used in hybrid cars. An NiMH is a rechargeable battery that is similar to a nickel cadmium (NiCd) battery, but that has double or triple the capacity of a NiCd battery. It's best not to overcharge NiMH batteries.

NiCd - NiCd stands for Nickel Cadmium, and is a type of rechargeable battery commonly used in toys, electronic devices, and power tools. Although some people prefer NiMH batteries to NiCd batteries, a NiCd battery provides virtually the same level of voltage throughout its lifetime, and costs less than an NiMH battery.

LiION - LiION stands for Lithium Ion, and is one of the newest rechargeable batteries. Although they are more expensive than other types of rechargeable batteries, LiION batteries have more capacity and are often used in wireless phones, camcorders, and notebook computers. The downside of LiION batteries is that the length of their life commences from the date of manufacture, rather than from the number of times the battery is charged and discharged. It's best to regularly charge LiION batteries and store used batteries in the refrigerator. (Allow them to warm to room temperature before using them, though.)

Alkaline - Alkaline batteries are not rechargeable with a battery charger, but offer a large current over a long period of time. These batteries are often used in CD players and portable radios.

Carbon Zinc - Carbon Zinc batteries are known for their reliability over long periods of time in low-drain situations, such as for garage door openers or clocks. A Carbon Zinc battery is not rechargeable.

A Shopping Comparison: Xbox 360 and Playstation 3

2007-10-10T05:15:00.000-07:00

Products such as Microsoft's Xbox 360 and Sony's Playstation 3 have grabbed undeniable attention in the consumer electronics market. During holidays, birthdays and other occasions, parents rush out to get the latest games or consoles to give as gifts to their children. But unlike more general products and gifts such as handbags, items for pets, household products, knives or leather goods, the electronics products such as these often come with an ongoing price tag, with new games being released indefinitely. That's why consumers should compare these products carefully before buying.

A Power Comparison

Electronics can be compared in several areas, with one being power. The Xbox 360 overwhelmingly surpasses the Playstation 3 when it comes to power. Its CPU (central processing unit) and GPU (graphics processing unit) have more processing power than the PS 3. The memory bandwidth of the Xbox 360 exceeds that of the Playstation 3 by five times!

However, don't let the power capabilities be the only determining factor. Playstation 3 still has lots of power when compared with older consoles, and the graphics are terrific as well. Also, it has a unique "cell chip," which is expected to help developers get even more power for games, but it's yet to be seen what will come of this. In comparison, there are still a couple of other things to consider.

Software Availability

The software (or video game) war is on now more than ever. Games are being defined by play-time, number of levels, quality of graphics, reality factors, and how they can be used online. Kids and adults alike are anxiously awaiting new games to be released to put them to the test in all these areas. Those wanting the online capabilities will find that Xbox 360 is geared that way.

With so many independent software developers, games are being released today that are either/or when it comes to the console Those who own a Playstation 3 console will be able to buy the PS 3 version of the game. The same goes for Xbox 360! So, this makes it more difficult to differentiate between the consoles in terms of the types of games offered. It's the actual features and capabilities of the console that will determine the consumer's final decision.

Pricing for Consoles and Games

Pricing is another determining factor. It's usually based on the "newness" of the console or game. However, with new games and consoles being released, consumers won't find cheap prices on these electronics just yet. It's like buying automotive parts for a brand new car - there are no used or discounted parts because it's all new!

Unlike buying jewelry, leather goods or a gift set of kitchen knives, choosing the right game console has to be a personal decision based on the features and capabilities desired. Many electronics are designed that way thanks to the ever-changing world of technology!

The Top 3 Problems With Plasma TVs

2007-10-06T01:59:00.002-07:00

It's easy to be instantly drawn to a plasma TV screen, especially one that is displaying full HDTV programming. The visual beauty is amazing. And plasma TVs tend to be among the lower cost thin screen technologies that are available today. But there are a few problems inherent to the design and you should at least be aware of them before making a buying decision.

The first is that plasma TVs use inert gases that are illuminated to display colors on the screen. The way that this is accomplished makes for very high contrast, vivid images on the screen, but it also can be affected by high altitudes. If you live above 6,000 - 7,000 feet above sea level, you should know that plasma TVs have to work much harder to produce the same image than they would at lower altitudes. This may not cause an immediate problem, but over time the monitor wears out much faster due to the extra work load. So if you happen to live in high altitudes, just bear this in mind when buying a plasma TV.

The second problem that plasma TVs can exhibit is a susceptibility to screen burn-in. This happens whenever any static image stays on the screen for a very long time and is still faintly visible even when the image changes. It is said to have been "burned-in" to the screen, and can be very irritating to see a ghost pattern still visible as you watch TV. The easy way to avoid this problem with older plasma screens is to make sure that you don't leave the TV on when you are not watching it, and especially when pausing a video game for a very long time. Thankfully though, newer plasma screen TVs have technology built in to address this problem that subtly shifts the image to surrounding pixels as you watch and essentially keeps the image moving although your eye does not detect it.

The third plasma TV problem that we will discuss is the heat it generates as it runs. Plasma screens often cause so much heat inside the unit that manufacturers usually install a fan to cool it down while operating. This actually works very well, but on some models the noise that the fan makes can become an annoyance. So listen for this problem carefully before you buy.

None of these problems are major enough to say that you shouldn't buy a plasma screen TV, but they should be understood beforehand so you can use the equipment properly, and choose the right plasma TV when you buy.

Plasma TV or LCD - Which Should You Choose?

2007-10-06T01:59:00.001-07:00

When it comes to high quality flat screen TVs, there are a number of choices available these days and the technology is constantly improving. However, as each competing TV screen technology matures and improves, the differences between them become more difficult to detect. And so it is with the comparison between LCD and plasma TVs.

The big advantages of both kinds of TV monitors is that they are very thin, only a few inches thick. Because of that you can choose to either place them on a stand, as you have with televisions you have owned in the past, or mount them to the wall instead. They both also produce stunningly beautiful visual displays, especially when coupled with high definition television programming. But there are some subtle differences that you will want to be aware of though.

Plasma TVs have been in use for many years and they use inert gases that are illuminated to display colors on individual pixels on the screen. Their best feature is the high contrast image that they reproduce. The colors are extremely vivid and sharp and this is mostly due to the fact that plasma TVs are able to exhibit true saturated blacks, whereas other monitors, LCDs included, usually have some compromise in how much true black they display.

Plasma screens are also easily viewed from almost any angle and so if you have a wide room with seating that extends out at an angle from the front of the television set, you may want to consider this advantage, although recently many LCD TVs have been steadily improving in their accepted viewing angle.

One area that plasma TVs have historically had a disadvantage is in the amount of electricity needed to power them and how hot they run. It can cost more to run a plasma TV if you use it very regularly, and it can generate quite a bit of heat inside, enough to warrant most manufacturers making use of a fan to cool them down as they run. This is not a noticeable problem unless the fan makes noise that can be distracting. So be sure to actually view a plasma TV before buying that particular model and see if the fan noise is a problem.

Another quirk of plasma TVs is that they can be susceptible to screen burn-in, which happens when one image is left on the screen for a very long time and it then becomes "burned into" the screen so that you can still faintly see it even when another image is displayed. This can happen on some TV channels that display an image that stays in a certain part of the screen for a long time, and if you play video games, there may also be a possibility that some games can cause this problem. So ask yourself before buying how you intend to use the TV, and if you happen to view programming that may have static screen images a lot of the time, it may be wise to choose an LCD screen as it does not suffer from this problem.

LCD TVs may not produce deep contrasty images like plasma monitors do, but the colors are still very pleasing and they can also be a better choice for brightly lit rooms since their display is not as susceptible to ambient light influences. However, they can tend to get more pricey than plasma TVs once you go above the 40 inch screen size.

All in all though, either type of TV screen technology will do a great job for you. The best recommendation is before you buy, visit a local electronics retailer and view representatives from plasma screens and LCDs. Bring along your own movie that you are familiar with and look for the differences. Then choose the one that makes the most sense to you. There is no need to buy from the store as you can often save lots of money by making your purchase online instead, but by doing your homework you can make a more informed buying decision.

Choosing The Best Cell Phone

2007-10-06T01:58:00.001-07:00

Choosing the best cell phone takes planning and the knack for really knowing yourself. Your cell phone has to fit your lifestyle, and that includes your budget. Almost all cell phones require you committing to a long term contract with a cellular company, so make sure you read the fine print, in order to avoid any disappointments later on.

Armed with the knowledge of how much you want to pay, you can quickly decide what features you want. Herein lies the secret to choosing the best cell plan: when you know exactly what you want, and how much you're willing to pay, you can always find just the perfect phone.

Some principles to base your cell-phone purchasing decision on:

1) Not all cellular carriers or networks are created equal
2) Phone quality directly affects customer satisfaction

This means you need to do your research in order to find out what type of phone and what type of cellular plan is right for you. Find out what people who already own the phone are saying. Research customer reviews and notate if anyone has brought up certain issues or problems with plans or providers. It might seem painstaking to do this level or research, but the hours of hassle it saves you later on will be well worth it.

Several key components of picking the best cell phone are:

1) Cell phone styling and features - loads of features and sleek design is what most people want
2) Reliable and cost-efficient cellular plans - cell phones are monthly bills, people who pay monthly want a good service that works

Cell phone styling varies widely in range, and it's recommended that you look at and hold several different styles of cell phones to get a good feel for what to expect. A phone that doesn't feel right in your hand, will be one you're unhappy with. The easiest way to see a variety of cell phones is by visiting a local retailer. If the screen is hard to read, or the keypad is difficult for you to work with, you need to factor that into your decision to buy. Keep a small checklist of the pros and cons of the purchase. If the cons outweigh the pros, then decided against it.
Next make sure to rigorously investigate the cellular plan you're expected to purchase, and read it before entering into the agreement. Make sure all fees are disclosed, and that you understand what you're agreeing to in terms of total payments. It's better to be careful up front, than regret the decision for years.

Expectations of cell phone consumers is high, and it's no wonder why: with over 800,000,000 phones sold in 2005, this is one of the most popular products in the world. Companies ranging from Nokia to Sony Ericsson make millions of units monthly and ship them to locations around the world. Education is the best tool that a cell phone consumer can have these days.

Should I Buy A Laptop Or A Desktop?

2007-10-06T01:57:00.001-07:00

With the advances in computer performance technology moving forward in quantum leaps it has created some difficult questions for us, one is deciding between a laptop or a desktop.

Now, not only do we have the problem of our computers being outdated very rapidly but we also need to decide which route to take.

Let’s look at the pros and cons and identify what we will use our computer for so that we will be able to make an intelligent decision about it.

First let’s look at the laptop. Obviously the greatest benefit to a laptop that is glaringly apparent is the mobility. This allows you to always be able to take your computer with you to work, school, on vacation, etc. At the same time this portability also allows anyone else the ability to walk off with your laptop as well. If this happens, not only are you out a computer but you have also lost all the data you had on it as well so security is a concern.

Another issue is the price difference. While prices have come down, there will still be a good disparity in the price of a laptop to a comparable desktop so you have to weigh that out as well. The difference is usually $400 or $500. Do you need the mobility enough to pay the difference in price?

Another concern with purchasing a laptop is the availability of parts and how upgradeable the unit is. Don’t buy some off brand laptop that you won’t be able to buy parts for and don’t buy one that you can’t upgrade later.

A big issue for me is the size of the screen, yeah size matters. If you get a laptop with a small screen you will be aggravated, trust me. I have a 17” screen on my desktop and a 15” on my laptop and it really makes a difference. You can get a laptop with a 17” screen, it will just set you back a bit more in cash outlay.

So ask yourself these questions:

Do I mainly use my computer at home or do I need it at work or school?

Do I travel a lot?

Will I use the laptop?

Am I willing to pay more for the convenience?

Stop Computer Hackers

2007-10-06T01:22:00.000-07:00

Though I do not understand computers very well, I have used a computer since about 1993. Now that my fingers are no longer so flexible I love my computer even more than before. Using E-mail I am able to correspond with friends and family. And I am able to keep my thoughts organized using my word processor.

But there is one thing about computers which I absolutely hate -- hacking! Hackers deserve jail time regardless of their age. They are guilty of causing great monetary losses to their victims -- you and me.

They are guilty of creating frustration and aggravation for those of us who are simply trying to enjoy using our computers. Hackers may be very bright when it comes to understanding computers but they are ignorant, thoughtless and uncaring when faced with the consequences of their actions.

Personally, through the years I expect I have spent at least 100 hours troubleshooting various problems. In addition, I believe I have spent about $5000 in upgrading and/or replacing my computer and in buying software to prevent the problems which hackers create.

Recently I read that successful hackers could also steal your identity. Now this is frightening! Viruses, trojans, adware, and slow loading or non-functioning computers are bad. And now we learn that hackers could actually steal your identity!

Where will it all end?

Computer protection programs are available. But many, if not all, do nothing to stop someone from sending problems to your computer. However, some of those programs are quite efficient in removing those problems, once a problem is recognized. It seems prefferable to stop the problem from being placed on your computer in the first place.

I have found a program which I believe will stop computer hackers. I downloaded a program called Security Suite which can run continuously in the background and stop hackers from gaining access to your computer. Downloading took less than a minute. And after the free scan revealed no problems on my computer I feel secure.

Considering that the program comes with a full eight week money back guarantee, there is nothing to lose.

The free scan is highly recommended even if your computer is running smoothly. I believe you will agree that this product is worthwhile both for your peace of mind and for your personal, or business, security.

A Look At Conference Call Services

2007-10-05T05:27:00.000-07:00

In general, conference calls are designed for individuals who wish to make a call to have the option of multiple parties on the same line. A conference call can be set up in one of two ways, which includes a situation where only the caller speaks and the other parties simply listen or, in some cases, the listeners can also talk during the call. In short, a conference call can either be a one-sided call or one that involves the participation of all parties.

Conference calls can include the option of the caller actually making calls to the other participants or, in some cases individuals can call directly into a conference call by using a special telephone number. Most local telephone services offer three-way calling, which is a small variation of a typical conference call though the theme is the same. With three-way calling, multiple parties are permitted to use the same line during a conversation. This is ideal for phone customers who wish to speak with multiple family members or friends at the same time.

In the past, conference call services were reserved to only customers who subscribed to this option via their local telephone company. Today, however, conference call services are widely available online and are adding up to big savings on the telephone bills of many participants. In many cases, individuals often use video conferencing, which is the next level above conference calls.

A popular resource among most businesses, conference calls are used as a way of connecting business executives who are miles apart but need to speak to each other in an organized fashion. In addition, conference call services are very popular for use as a ‘party line.’ This is simply a specific line that allows multiple individuals to talk with one another via a specific telephone number. Although conference call services are most effective for business use, they are not completely out of the realm of possibilities for consumers and even entrepreneurs who work at home and need to connect with others.

Before deciding to sign up for conference call services from any one particular company, make sure that you take the time to shop around and compare rates from similar providers. Whether you are using conference call services that are provided through the telephone company or you wish to use those offered online, smart shopping applies to every aspect of life and this includes common everyday utilities.

Surveillance Systems – A Legal Big Brother?

2007-10-05T05:26:00.000-07:00

Surveillance systems, with all the sleek gadgetry have turned security into a high technology oriented big industry. Can you imagine what the small and concealable surveillance cameras can do to a country? US used satellite and aerial surveillance systems of the highest degree of sophistication, as recently as 2003-04 in Iraq and Afghanistan. This is the latest in international, state sponsored surveillance exercise of this magnitude. But this is not the first, or not in the least, the last. The 1965 demand of New York PD was honored by the Federal Government in 1969 and the first video cameras were installed in the New York City Municipal Building near City Hall.

Surveillance Systems for Public Security Use of surveillance systems soon became the norm in cities of political and strategic importance with the earlier analog video cameras being installed in public places. To name a few, Statue of Liberty and Lincoln Bridge were immediately covered by cameras for surveillance. Many crimes were either prevented or detected like never before. Still, the use of surveillance in America lags behind UK. The London Metro is the critical place where they have an extensive installation, which proved effective in the recent bombings.

State and private detectives use surveillance systems for their day to day work. The equipments they make use of are quite interesting as they are little marvels of technology. Body wearable spy cameras score on top of all of them. They come in different sizes and shapes making it easier to wear and conceal. They are mostly button shaped and most of them transmit their captures I instantaneously while some can store data for later retrieval.

Digital spy cameras which can be concealed anywhere inside a building sells for around $60, have 300’ wide angle and focal length of 6’. The smallest one measures 2CM x 2CM.

Phone bugs can’t be ignored at all. They have countless disguises like series transmitters, induction taps. They can be placed with the receiver of your phone, within the telephone box or even the near power socket. Don’t under estimate their capacities; they operate at 78 - 88MHz but professionals use range of 150-475 MHz to avoid detection. Price varies between $14.5 and $145.

‘Ear Spy’ helps hear across rooms through powerful devices connected to ear phones via long cords. Remote transmitter models have capabilities of 40-50GHz and various amplifications. Price ranges from $6 -$24.5

Home security is not quite different from public security system on certain counts. Some other popular equipments are GPS and GPS enabled cell phones are handy in tracing criminals and hostages.

How plasma TVs work.

2007-10-05T05:25:00.001-07:00

We're all familiar with the common cathode-ray tube (CRT) technology that has been the backbone of television for decades. Inside each CRT, an electron gun similar to a laser fires a negatively charged beam of electrons at groups of gas molecules (the pixels), which causes them to change color; producing the pictures we see everyday. These televisions work well and produce very crisp pictures, but they are notoriously bulky and heavy. This is because as the screen gets larger, the electron gun must be moved farther back so that it has a good angle to hit every pixel with its beam. Thus, the larger the screen, the deeper the TV.

Enter the plasma flat panel television. Arriving with the turn of the millennium, these televisions come in large, widescreen models that measure only 6 or 7 inches deep; a huge improvement over CRT. This dramatic change in shape results from individual transistor electrodes at each pixel. We no longer need the laser to hit every inch of the TV and, without the laser, manufacturers can eliminate most of the traditional bulk. The individual pixels in a plasma TV are composed of 3 fluorescent light cells: one red, one blue, and one green. The television produces pictures by varying the intensity of each cell to produce a unique color at every pixel without a laser. These lights give the television its name because they contain free flowing ions called plasma. The plasma, when hit with an electrical charge, produces light.

Traditional CRTs used the electron gun, or laser, to charge each pixel and create colored light. Plasma TVs instead have two sets of electrodes, one set running vertically and one set running horizontally. The horizontal set, which runs across the front of the screen, and the vertical electrodes, which run across the rear of the screen to form a grid like a checkerboard. The computer, by sending pecific charges through a single vertical and a single horizontal row, can color one pixel of plasma at a time. When the various sub-pixels are charged, the gas molecules inside release light particles called photons. The problem here is that photons are typically in the ultraviolet spectrum, and invisible to the naked eye. However, as they are released, they strike the surrounding surface of the cell. These surfaces have been specially coated with phosphors. A phosphor is a chemical that produces light, but only after being hit by another source of light. So, the invisible, ultraviolet photons strike the phosphor, creating a spectrum of light that our eyes can see.

Depending on how the three sub-pixels are charged, we may see a greener, redder, or bluer shade. These primary colors may combine to produce one of a million different colors. If you think about the basics of this technology, each light cell is a miniature fluorescent light. This produces the brilliant, flicker-less picture we see when we watch a plasma television. Now you understand the technology behind the plasma flat panel television.

Metal Detector Buying Guide

2007-10-05T05:24:00.000-07:00

If you were one person who loves adventure in the form of treasure hunting, then a metal detector would be one of your necessary equipments. Be it out of sheer hobby or more on the professional level, you really would not perform well treasure hunting if you do not have a good metal detector to explore with.

A metal detector is one sophisticated device that leads you toward gold mines. A good metal detector would sure find some small treasures buried in sands, in soils, and in other obscured places. A good, wholesome fun is sure to be delivered by this ingenious device.

If you are planning to buy a metal detector to join the treasure-hunting fun, here are some tips to guide you so that youll get the best deal possible. Metal detectors can be pricey, so youve got to invest your money well.

1. Determine where you are going to use the device at

There are certain features needed for certain places the device is going to be used for. If you intend to use it on the beach, the terrain wont be that rigorous. But you are going to need waterproof protection. If you wanted to use it more rigidly, then you should opt for the one that is especially made for all kinds of terrains.

2. Estimate for how long you are going to use the detector

The hours of operation a metal detector is determined by its model. Some are made to work for as long as 24 hours a day. Some cant perform as much. This is decided by the battery life of the device you are going to purchase. Also decide if you rather have extra batteries or if you prefer to get a charging kit.

3. Know your budget for it

As stated earlier, metal detectors could really be expensive. You can cut on cost if you cut on features. Try to look for the best bargain by enumerating the features you are going to need against the one that you can leave off. Also, be on the look out for brands that are big on features but small in price. Now thats a real good deal.

4. Research the latest technologies

As with other electronic equipments, innovations seems to always happen overnight. If you are going to buy a metal detector today, try to know that technologies are currently employed. You do not want to be behind the technology line, right?

5. Get some professional advice

Get an advice from people who are the known authorities in the field of metal detectors. Although families and friends are good sources of information, they might not be as updated as the experts are. If you wanted to get the best device possible, get first-hand information from the experts themselves.

6. Consider durability

Youve got to buy a metal detector that could withstand normal wear and tear longer than its competitors. The longer the metal detector can serve you, the better your return on investment will be.

7. Consider accuracy

Of course, the metal detector has to perform, and very well at that. It should deliver accurate detection. It should also carry out the task real well. It should spot treasures at once, and in a very precise manner. This is important because this is its main job out on the field. If it cannot detect small jewelry, as it should, then it is not worth buying, no matter how a good deal it seemed to be.

8. Get the most adaptable one

This can be determined by the metal detectors ability to be upgraded, when possible. Get the one that has a lot of devices that can be attached or added to it to make it work better. Do not settle for the detector that is relatively stagnant. If the detectors features can be enhanced further, the better buy it is.

These points could serve as your guide in buying a new metal detector. The more advantage points the particular type of detector you are eyeing for has, the better buy it is. Just make sure that you cash on the every feature you paid for. Buying a metal detector is a real decision. Buying that one is an even harder job. Follow these steps and you are sure to be guided accordingly.

How To Buy Used Metal Detectors

2007-10-05T05:23:00.000-07:00

Once you have decided to buy a metal detector, you have to decide whether you want to buy a brand new instrument or a second hand model. If budget is a constraint, a used metal detector will be a better option. If you are wondering how to buy a used metal detector, here are some useful tips, which will guide you in your purchase.

What are the types of metal detectors?

There are various kinds of metal detectors available in the market, meant for different purposes. The most easily available ones are gold detectors, coin and jewel detectors, relic hunting detectors, beach-hunting detectors, and underwater metal detectors.

What are the factors that I should take into account before buying a used metal detector? Consider the following points before your purchase:

· The amount of usage of the detector: If you plan to use it for a new hobby, choose an instrument offering various features.

· Location of usage: Decide if you plan to use it on the beach, below water or in the forest.

· Decide on who will use it: For a family use, there are detectors with adjustable arm cups and separate pouches to place the electronic box.

· Budget: Compromise on your budget to some extent so that you can buy the one meeting a majority of your needs.

Where should I buy?

A secondhand metal detector is a good bargain for your money. However, ensure you buy it from a reputed dealer rather than from an advertisement in your local newspaper. A reputed dealer will give you a money back guarantee or allow you to exchange your old one. This is because they test and then sell the detectors. If you choose to buy from any other source than buy from a good dealer or from a person you trust.

What are the prices of the used metal detectors?

All-purpose metal detectors carry a price tag of $275 to $700. Underwater metal detectors come at a price of about $500. The secondhand accessories come at the price of $200. But the only drawback is, there is no manufacturer’s warranty but at least buying from a good dealer will provide some safety.

Recent Progress on Pb-free Electronics at IBM

2007-10-05T05:16:00.000-07:00

Lead-containing solders have been used extensively in microelectronic interconnect structures between various packaging levels. Since the RoHS enforcement date of July 1, 2006 by the EU is rapidly approaching, the transition to Pb-free solders is accelerating in the electronics industry.1

At IBM, considerable R&D efforts on Pb-free solders technology were conducted well before the RoHS and WEEE Directives were enacted by the EU, as noticed in the early publication and patent literature.2-5 An example of the application of Pb-free technology within IBM is the usage of Bi-Sn eutectic solder for low-temperature wave soldering of plated through holes (PTH) in advanced multilayer PCBs since the early 1970s.6-7 IBM’s early work led to the National Center for Manufacturing Sciences (NCMS) Pb-free solder project, the first industry-wide joint effort to search for Pb-free solders. When the final report of the NCMS Pb-free project was published in 1997, it was dedicated to the memory of Roger Wild (former IBMer) for his pioneering work on Pb-free soldering technology at IBM.8

Fundamentals

Recently, worldwide R&D efforts on Pb-free solder alloys have identified several promising candidates for different soldering applications, as listed in Table 1. Two major Pb-containing solders, eutectic 63Sn-37Pb and Pb-rich solders used for SMT and flip chip or C4 (controlled collapse chip connection) solder bumps are also included in Table 1. It should be noted that the compositions of most Pb-free solder candidates are Sn-rich solders that contain more than 90% Sn. This suggests that the physical, chemical, and mechanical properties of the proposed Pb-free solders are heavily influenced by the properties of pure Sn, as opposed to eutectic Sn-Pb, which microstructure consists of a mixture of Sn-rich and Pb-rich lamellar phases. Pure Sn is polymorphic, capable of existing as three different crystal structures (∝, β, γ) depending on temperature and pressure.9 Since the white tin phase (β-Sn) has a body-centered tetragonal (BCT) crystal structure in contrast to the face-centered cubic (FCC) structure of Pb, the physical and mechanical properties of white tin are less isotropic and more difficult to mechanically deform in comparison to Pb. Since the white Sn crystal is optically birefringent, polarized light microscopy can be used to distinguish the orientation of β-Sn dendrite structures in Pb-free solders.10

The melting point of most Pb-free commercial solders is within the range of 208º to 227ºC, which is about 30ºC higher than the melting point of eutectic Sn-Pb at 183ºC. The higher melting point has serious implications on the performance of packaging materials and assembly processes, and can affect the integrity and/or reliability of Pb-free microelectronic packages. Another important issue associated with the proposed Pb-free solders is the difficulty of maintaining solder melting-point hierarchy, which has been well established with Pb-containing solders. With the proposed Pb-free solders, the maximum differentiation in solder melting temperatures between any two package levels is less than 30ºC. The process control, during successive multiple soldering processes with Pb-free solders, becomes more challenging and its impact on solder joint and package reliability is not yet well understood.

Among the several Pb-free solder candidates, the near-ternary eutectic Sn-Ag-Cu (SAC) alloy compositions with melting temperatures around 217ºC is the consensus solder alloy for SMT card assembly, including BGA solder joints, while the eutectic Sn-Cu or Sn-Ag-Cu alloy is a promising choice for Pb-free flip chip applications.11-14

Pb-free Ceramic Ball Grid Arrays

IBM’s development team conducted evaluations, using a number of criteria, in the early phase. Sn-3.8Ag-0.7Cu (SAC in wt. %) was selected based on its excellent wettability to I/O pads, stable microstructure of solder joints, superior ball shear strength, and the excellent thermal-mechanical fatigue (TMF) behavior of assembled modules subjected to accelerated thermal cycling.15 Further work with SAC confirmed that it was an optimal replacement alloy for Sn-Pb CBGAs for both 1.27- and 1.00-mm pitch.16

Reliability evaluation was performed with co-fired multilayer 9211 (alumina-based) ceramic test vehicles (32.5-mm square to 42.5-mm square, with thickness ranging from 1.50 to 3.70 mm). Five ceramic modules were attached by using SAC solder balls to a FR4 test card (6S4P, 229 × 279 mm). A typical cross section of a CBGA solder joint connecting a ceramic module to a Cu pad on a PCB (as-joined) is shown in Figure 1. Standard accelerated thermal cycle (ATC) testing (from 0° to 100°C, with 2 cycles/hr.) was used on the assemblies with a periodic, 4-point resistance measurement. An increase in resistance of 10 Ω or greater was used to define a failure. Table 2 summarizes the MTF data of Pb-free CBGA modules in comparison with the Sn-Pb, IBM dual-melt structure as a benchmark. The N50s were calculated by fitting a lognormal distribution to the fatigue data. All of the SAC alloy test vehicles produced well-controlled fatigue life as indicated by the small sigma. The SAC alloy has almost twice the fatigue life of the dual alloy Sn/Pb structure, for the same form factor. The full melting of SAC balls during assembly causes a smaller joint height with the SAC structure than the Sn-Pb structure. In spite of the unfavorable ratio of joint heights (1:2), the SAC alloy demonstrates the superior fatigue properties over the Sn-Pb for the same form factor. The TMF performance of SAC, combined with the relative lack of complexity in manufacturing these assemblies, makes the Pb-free CBGA technology a winner on all fronts.

Pb-free PBGA

The transition to Pb-free soldering technology has been juxtaposed on other market forces driving PBGA packaging toward high-performance, higher I/O, and high-reliability applications. The confluence of all these factors in time has made the development of Pb-free organic packaging technology a challenging watershed to cross. The higher reflow temperatures associated with Pb-free packaging technology have mandated the use of new organic packaging materials with improved water absorption characteristics, reduced CTE’s, and improved thermal stability. Higher reflow temperatures and the accompanying evolution toward higher I/O and larger chip sizes result in higher package stresses and place more stringent requirements on interfacial adhesion within electronic package structures. The stresses fostering package delamination derive from CTE mismatch, from increased steam pressurization within the packages, due to the presence of absorbed moisture, and in the case of flip chip packaging from the full melting of the C4 bumps within the underfill encapsulation. The choice of solderable surface finish and its bearing on solder joint fragility is a significant concern across the industry at this time. In this regard, IBM has chosen Cu pad structures as the surface finish for most of its packaging requirements. Successful Pb-free packaging, capable of passing stringent reliability testing, has mandated improved materials and significant interfacial adhesion augmentation.

Wire-Bond, PBGA Packaging. IBM has produced Pb-free wire-bond PBGA packages since early 2002 in both glob-top and overmolded configurations, and expects to be qualified to produce Pb-free and halogen-free products by the end of 2005. Package sizes range from 15 to 45 mm, with 1.27- and 1.0-mm BGA pitch. To achieve these results, new glob-top and overmold materials were developed in close working relationships with materials suppliers. The new materials have improved adhesion and moisture absorption characteristics, together with improved wire sweep processing characteristics capable of accommodating complex wire-bond trajectories.

Flip Chip, PBGA Packaging. Flip chip packaging is associated with a broader range of packaging challenges in achieving a successful transition to Pb-free soldering technology. New BLM (Ball Limiting Metallurgy or UBM) structures are required to accommodate the use of high Sn, Pb-free, solders. The full melting, Pb-free, C4 structures provide for higher internal package stresses during reflow because the bump volume increase associated with the melting process is constrained by the underfill encapsulant. The use of new underfill materials was required to meet the Pb-free reflow requirements. In addition, new thermal solutions and lower CTE laminate materials were incorporated to improve package reliability as the simultaneous evolutionary transition was made toward higher-performance modules. Package qualifications have been successful with the new organic material set and solder alloys. Flip chip PBGA products are now qualified from 15 to 42.5 mm for both 225- and 200-µm C4 pitch with 1.27- and 1.0-mm BGA pitch. Future extension to 55-mm package size is anticipated in the near future.

Pb-free Flip Chip Solder Plating

IBM is developing a Pb-free C4 solder bumping process for flip chip applications in response to customer requirements and environmental regulations. IBM has been plating C4 solder (97Pb-3Sn) for more than 9 years using a TiW/CrCu/Cu BLM structure.

The development approach for Pb-free C4 plating incorporated several key ground rules. A multifunctional team including development, process, equipment, quality, reliability and product engineering, analysis, research, and manufacturing was formed. Minimal changes to the existing successful BLM structure were desired. The new Pb-free process is designed to maximize use of the existing production line capital infrastructure and process for ease of manufacturing.

Two key components of the Pb-free C4 structure are the BLM and the C4 metallurgy. It is well known that the Pb-free, Sn-rich solders are highly reactive and, therefore, require a robust barrier metallurgy in the BLM to withstand aggressive high-temperature-storage (HTS) and electromigration requirements. IBM has been using a Ni barrier for other products, and chose to incorporate Ni as the barrier for Pb-free C4. For the solder metallurgy, we evaluated Sn-Cu as well as Sn-Ag-Cu (SAC) constructions. The evaluation criteria included ease of manufacturing, quality and reliability. From a reliability standpoint, the SAC and Sn-Cu solders performed equivalently. With our current tool set, the greater ease of manufacturing and better bump quality of Sn-Cu resulted in our choice of Sn-Cu over SAC. The construction IBM subsequently qualified for production is a TiW/CrCu/Cu/Ni BLM with Sn-Cu solder metallurgy, as shown in Figure 2. The first Pb-free C4 application that IBM qualified and put into production is a chip-on-flex one. We completed a production line qualification as well as a reliability assessment. There were no C4 fails in deep-thermal-cycling (DTC), HTS, low-temperature-storage (LTS), temperature/humidity and bias (THB), high-temperature-operating-life (HTOL) or ATC stresses. Electromigration performance of this Pb-free C4 was better than expected, between eutectic Sn-Pb solder and 97Pb-3Sn solder in performance. This application is now in production at IBM.

The key challenge for the future will be to provide Pb-free C4 bumps at 150-µm pitch and below. IBM is currently developing solutions for that application space. IBM has developed, qualified, and is in production for Pb-free C4 bumps. Qualification for additional applications is in progress, with a good prognosis for continued success.

Pb-free Wafer Bumping

Multiple transitions are presently occurring in the wafer bumping industry. Among these are increased wafer size from 200 to 300 mm, decreased bump size and pitch, alloy change from eutectic Pb-Sn to Pb-free, and the continued growth of flip chip vs. wire bond. At the same time, the demand for lower costs, finer pitch, and higher quality is unrelenting. In September 2004, IBM and SUSS MicroTech announced a new wafer bumping technology called “C4NP,” short for Controlled Collapse Chip Connect New Process, to address these challenges.

C4NP grew out of earlier work at IBM Research in which a new injection-molded solder (IMS) process produced advanced thermal interfaces. It was quickly realized that IMS could readily be applied for making solder interconnect structures. A parallel process, C4NP fills molten solder into small cavities in a bump template that matches the I/O footprint of a silicon wafer. After the solder is solidified, an inspection step ensures that all the cavities are properly filled. Separately, wafers are prepared with the appropriate BLM compatible with the desired solder alloy. The last step actually bumps the wafer, namely aligning the filled bump template and joining it in mirror-image fashion to the silicon wafer above the solder reflow temperature. This transfers the solder volumes from the cavities to the wafer. The bump templates are reusable, keeping costs low. Several advantages can be listed for C4NP:

* Alloy flexibility including multicomponent Pb-free alloys;
* No volume change from deposition to final bump; extendible to fine bump size and pitch;
* Same tool set for both 200-mm and 300-mm wafers;
* Low material costs in comparison to paste, preform, or chemical solution;
* Optimal yields by bump template inspection before transfer to wafer;
* Rapid turn-around time by prefilling bump templates ahead of wafer completion;
* Efficient solder usage for environmental and economic benefits;
* Extendability to finer pitch;
* Process simplicity similar to stencil printing.

As seen in Table 3, a comparison of other established bumping processes explains why C4NP is creating excitement in the industry. Considering the challenges ahead, the timing of a new bumping technology that combines high-end capabilities with low-end costs may be considered auspicious. More than 40 years ago, IBM first introduced C4 technology. C4NP, as the latest version, should provide a cost-effective solution to meet present and future Pb-free wafer bumping needs.

Tin Whiskers: What’s the Risk?

2007-10-05T05:12:00.000-07:00

The adoption of lead-free technology, driven by legislative requirements and market forces, has involved significant changes in materials, processes, and supply chain in the electronics industry. The changeover has raised a number of concerns for the electronics industry in ensuring product reliability while maintaining reasonable costs.

As the EU’s Restriction of Hazardous Substances (RoHS) deadline of July 2006 approaches, the industry has predominantly settled on tin-silver-copper as the replacement for conventional tin-lead solder. To comply with RoHS, part manufacturers have sought lead-free finishes to replace the traditionally used tin-lead finishes. The finish selection is important in providing corrosion resistance, good solderability, and durable solder joints. Currently, selected lead-free finishes include pure tin, tin-bismuth, tin-silver, and tin copper, and to a lesser extent nickel-palladium-gold and nickel-gold. Due to its low cost and compatibility with existing solders, the pure tin and tin-rich lead-free alloys have been adopted by a significant portion of electronic part manufacturers.

Particularly among the high-reliability product community (space, military, and high-end computer servers and storage), the adoption of pure tin and tin-rich lead-free finishes has raised a reliability issue pertaining to the formation of conductive whiskers. In 2002, CALCE in collaboration with individuals from NASA, Boeing, Raytheon, and the U.S. Navy, issued an alert outlining the potential risks imposed by the selection of pure tin and tin-rich lead-free alloys. The concern prompted several industrial groups, including CALCE, to examine the phenomenon of tin whisker formation, the effectiveness of various risk mitigation strategies, and methods for quantifying the risk presented by the use of these finishes in electronic products. As a gauge to the level of concern, iNEMI has three working groups on tin-whisker-related issues, and CALCE maintains a mailing list of individuals (engineers, scientists, and managers) from more than 60 organizations who have participated in a weekly forum on whisker-related issues that has been ongoing for almost 3 years.

While the phenomenon of tin whiskers has regained considerable attention during the past 3 years, key questions related to the tin whisker growth mechanisms remain. Major issues include:

Wide proliferation of pure tin and tin-rich lead-free finished electronic components in the market.
No consensus on tin whisker growth mechanism.
No recognized method of accelerating whisker formation.
No guaranteed method of avoiding tin whisker growth.

As a result, the industry continues to be challenged in answering the basic question of quantifying the risk presented by this wide adoption of pure tin and tin-rich lead-free alloys.

What Are Tin Whiskers?

For the uninitiated, tin whiskers are spontaneous growths of tin from tin-finished surfaces such as those shown in Figure 1. These growths can be in the form of nodules, needle-like filaments, or odd-shaped eruptions. The needle-like, straight whiskers are a chief concern, because there is a higher chance for bridging adjacent electrical conductors. Such bridging may result in excessive current leakage and/or electrical shorts in the electronic system.

The phenomenon of tin whisker formation was first reported in the 1950s by the Bell Telephone Co.1 To date, a wide variation in the growth characteristics, including length (0.3 to 10 mm), growth rate, and incubation time (days to years), has been reported. While leadframe parts have received significant attention, other parts including connectors, cover plates, and fasteners must also be considered at risk if finished with whisker-prone materials such as tin, zinc, and cadmium

For tin whiskers to form, tin must migrate to the whisker site. However, it is unclear if the tin moves along the surface or from under the surface. It may very well come from both routes. Although the exact cause of whisker growth is not completely understood, it is widely believed that compressive stress within the tin finish influences tin whisker growth.2,3 Stresses within the finish can arise from:

Intermetallic compound formation between the plating material and substrate, resulting in compressive stress within the plating;
Mismatches in coefficient of thermal expansion (CTE) of the tin-based plating material and substrate, or underlayer;
Presence of residual stress from electroplating process itself;
Extrinsic compressive stress, such mechanical bending and forming.

Regardless of the surface finishing technology, namely electroplating, hot air leveling, or immersion tin, tin whiskers have been observed to form. However, electroplated surfaces are considered to be a higher risk, since the electroplating process involves various parameters affecting the level of stress in the plating deposit. Key parameters include plating chemistry, organic additives, current density of the plating bath, and bath contamination. While the effect of those plating parameters on tin whisker growth is not fully understood, some consider mechanical handling, which the finished surface may be subjected to after the plating, to be even more critical.

Intermetallic formation between the tin plating and substrate material appears to be a contributing factor. In the case of tin-plated copper substrates a dominant diffusion species, tin, migrates relatively quickly through grain boundaries and dislocations, or more slowly through the bulk, resulting in Cu6Sn5 intermetallic (IMC) formation at room temperature. The scallop-like Cu6Sn5 IMC with density lower than that of copper is known to give rise to compressive stress within the finish. The usage of underlayer, such as nickel, is a possible means to reduce the effect of intermetallic formation on copper leadframes, because tin-nickel IMC grows slower than tin-copper IMC. In fact, some part manufacturers have adopted a nickel underlayer and its beneficial influence for retarding whisker growth has been reported in various studies.4-7 In the case of tin-plated alloy 42 substrate, compressive stress within the finish may arise under thermal cycling, due to a larger CTE mismatch with pure tin.

Review of the Electronic Component Market

For the past 3 years, CALCE has tracked the selection of finishes by more than 100 part suppliers and has observed a continued increase in selection of pure tin and tin-rich lead-free alloys for lead finishes (Figure 3). Tin-rich finishes have been a preferred choice, mainly due to the low cost, good processability, good corrosion resistance, and compatibility both with conventional tin-lead and lead-free solders.8 The finishes offered by a variety of part manufacturers include pure tin, tin-bismuth, tin-copper, and tin-silver.

Blu-Ray: How HD-DVD and Blu-ray Differ

2007-10-04T01:01:00.001-07:00

DVDs continue to be the prominent medium for home theater entertainment. The technology is being refined and improved upon by a number of manufacturers, making its future slightly uncertain though it is definitely clear that it will continue is one format or another. Many of you have probably been hearing about Blu-ray and HD-DVD discs and their path as the next generation of DVDs. The discrepancies between the two are confusing many home theater buyers, so its important to know just what each of these new technologies has to offer so that you can make an informed decision on what to purchase and when.

Lets start by discussing just what Blu-ray is. Chances are, if youve stepped into any of the leading home theater and electronics stores in the country, youve seen Blu-ray discs advertised in the DVD section. In truth, Blu-ray discs are somewhat like traditional DVDs, except that they have the ability to record, rewrite, and playback high definition (HD) video that is compatible with the growing number of HD televisions finding their way into home theaters every year. Unlike traditional DVDs, Blu-ray discs can hold nearly five times as much data. On a single layer disc, they can hold 25GB of data, and 50GB can be stored on a dual layer disc. By being able to hold so much more, Blu-ray discs are able to easily store the advanced information necessary to provide content in HD format.

HD-DVD offers the same technology, though it isnt able to hold as much information as Blu-ray. Developed by Toshiba and NEC, it is able to hold three times as much data as traditional DVDs. While this may be less than Blu-ray, the data capacity of HD-DVDs still exceeds the amount needed to watch major blockbusters in high-definition. HD-DVD also came out much sooner and was first quoted to be the successor to the standard DVD format. HD-DVD is completely compatible with HD-DVD players, which in turn are compatible with HD televisions. High definition technology is certainly the wave of the future for home entertainment, and HD-DVD was the first disc technology formatted for it.

Both Blu-ray and HD-DVD discs use a new form of laser that improves on what the standard DVD used. While older, standard DVD models used a red laser to transfer content from disc to player to screen, these two technologies use a blue-violet laser instead. The main benefit with using blue-violet lasers is that they have a shorter wavelength than red lasers. This means that they can be focused with a much higher rate of accuracy.

As you can see the differences between these two formats are very few, In short, Blu-ray is able to hold more information than HD-DVD, but HD-DVD has been around for much longer and still holds an adequate amount for any applications currently in the market. Both formats use blue-violet lasers to better read the information.

The biggest question right now is which format will end up on top. Blu-ray has the added advantage of being backed up by some major players in the movie business. Seven of the eight major Hollywood movie studios have released films in Blu-ray format recently, while five of them are releasing films exclusively on Blu-ray. HD-DVD has the backing of several major consumer electronics manufacturers but does have some ground to make up with the production companies. However, with the added experience of being in production longer and having consumers more familiar with the name, its very possible for them to pull ahead. The race to be the top home entertainment format will continue on and the consumer will simply need to wait to see which one wins. In the meantime, players are available for both formats and some manufacturers have players that satisfy both formats available.
