News: EL Wire Basics

EL Wire is a bit tricky if all you want to do is glow. But there's a lot to know about the technology, as well as helpful information to get you addicted to it. EL Wire is a thin copper wire that gives off a beautiful glow when an electric charge is applied. There are 10 colors of EL Wire, and each wire has it's own unique characteristics. Typically EL Wire is used for safety as well as costuming. It has such a low power point that it can run off as little as watch batteries to make it glow!

News: Super Eco-Car Gets 2,752 MPG

The upcoming Shell Eco-Marathon promises to unveil vehicles that will blow current fuel economy standards way out of the water. California Polytechnic State University is one of the most promising contenders, with a vehicle that gets 13 times the 230 mpg General Motors promises the Chevrolet Volt will deliver (plus, the Cal Poly car doesn't even use batteries!).

News: Turn a juice box into a camera

Look left. Can your garbage take photos like that? With a few tweaks it will! The pinhole camera is photography in its most basic form. Using a light-proof container, the 35mm will capture the image when the pinhole is opened. The resulting photographs have a distinctly démodé look, like this shot from Kodak's archive.

News: 6 Places to Get Canon 5D Help Online

Since our Canon 5D World is just starting out, there's not a lot of activity in the forum. If you have a question about your 5D or 5D Mark II, then ask away. But there are other communities on the Web that already have great information from its members. Hopefully, the Canon 5D World forum will be just as helpful to everyone, but for now, here are some of the best forums on the Internet that can help you with Canon's EOS 5D and 5D Mark II cameras.

Altruistic Hacking: The Rise of the DIY Radiation Detector

Understandably, the tragedy in Japan has substantially risen the level of worldwide radiation-related hysteria. So much so, as an alternative to stampeding health food stores for iodine tablets, crafty individuals and organizations are hacking together personal radiation detectors. Rather than relying on the government, the creation and modification of handheld Geiger counters provides a self-sufficient solution to today's questions regarding radiation. Profiled below, three admirable organiz...

News: Carnivorous Furniture Eats Flies and Mice for Energy

PETA wouldn't consider James Auger and Jimmy Loizeau's ingenious flypaper clock very eco-friendly, but I might beg to differ. The clock doesn't require any electricity or batteries. Instead it captures flies and converts the bodies of the dead insects into energy. Eight dead flies makes for roughly twelve days of power. Not bad.

News: OCD Iron Man Nut Builds SPECTACULAR Suit Replica

25-year-old Anthony Le, of Colorado is THE ultimate Iron Man fan. A cosplay fan, Anthony decided to try his hand at building a super realistic Iron Man suit, just in time for the release of Iron Man 2. The incredibly talented fitness consultant did above and beyond what you might expect. Check out the two videos below. Le's insane suit features the following: a dent-proof exterior, a motorized faceplate, and a spinning mock Gatling gun. He spent one month and approximately $4k building his ma...

TVs Are for Old People: A Guide to Handheld Consoles

Advancements in technology usually lead to the miniaturization of old technologies, and video games are no exception. Since at least 1990, game hardware manufacturers and enterprising DIY electronics enthusiasts have poured their efforts into making full-size video game consoles smaller, even handheld. And for good reason—who would have ever played a black and white Game Boy if they could have had an actual NES in their pocket?

New Game by Hasbro: Electronic SCRABBLE Flash

Nope, this isn't a flash game version of SCRABBLE. There's already one of those (and a multitude of imitations) for the Apple iPhone, iPod, and Facebook. This is an electronic game, and it's not a "handheld" game like the SCRABBLE Pocket Pogo Touch Screen Game (pictured right). It's an entirely new way to play everybody's favorite word game, and it's called SCRABBLE Flash (BOGGLE Flash outside of the U.S. and Canada).

How To: Make Surface-Mount Electronics at Home for Smaller, Cheaper DIY Gadgets

Whenever we make a homemade circuit, we use what are called through-hole components. Any components with long metal leads is a through-hole component. They are great for soldering to, but it's tough to fit enough through-hole resistors and capacitors into a smartphone. To get those last microns, we have surface-mount components for SMDs (surface-mount devices). These are all of those teeny, tiny things you see when you crack open your digital camera or laptop case.

How To: Design Your Own Custom Arduino Board Microcontroller

Microcontrollers are great. You can do anything from water your garden to catch wildlife trash diggers in the act—and on the cheap. I prefer to use the Arduino microcontroller because of the large and helpful community built around the website. Though it is my favorite, there are some drawbacks to using an Arduino board in every project. It gets expensive, the board can take up too much space, and the rat's nest of breadboard wires are a pain to repair.

How To: This DIY Soft-Circuit Military Tech Lets You Power Electronics Using Your Clothes

It turns out that the popularity of soft circuit electronics has leaked out of the interwebs and into the hands of the U.S. military. Soft circuit electronics allow you to literally sew electronics circuits into fabric using flexible conductive thread instead of wire. Soft circuits can be used for all sorts of fun projects, like the TV-B-Gone Hoodie and the Heartbeat Headband.

Making Electromagnetic Weapons: EMP Generator, Part One

In this series, I'll be exploring electromagnetic weapons, how to build them, their function and application to the future, and the amazing possibilities electromagnetism has to offer. First, the electromagnetic pulse generator, or EMP. You've probably heard of these before, and their devastating effects on electronics. A simple EMP consists of a capacitor, transformer, trigger, and coil of copper wire. This, when triggered, would produce an intense magnetic field for a brief period, similar ...

A First Look at Call of Juarez: The Cartel

The developing team Techland gets a free pass. Having thoroughly enjoyed their previous title, Call of Juarez: Bound in Blood, this sequel was bought on day one by good ol' fashion blind faith. After playing for most of today, it's still to early to tell if the game is a mess or a fun romp. Here are some first impressions.

How To: Sprint HTC Evo 4G Impressions

Spent the weekend with Sprint's new phone, the HTC Evo G4. Specification wise, it's better than Verizon's Incredible and T-Mobile's HD2. Apple will be announcing the new version of their phone this week. If it's comparable to leaked phone shown over at Gizmodo, then to say which phone is better is debatable. The iphone might have a better battery life but the Evo has an unlimited data plan, unlike AT&T's new tier pricing structure.

The Sprint HTC Evo 4G: Best Phone This Year

Written by JD Coverly of WonderHowTo World, LoadSave:We've spent the last week with Sprint's new phone, the HTC Evo 4G. Specification wise, it's better than Verizon's Incredible and T-Mobile's HD2. Apple has unveiled the new version of their phone this week and thankfully it's debatable as to which phone is better. The iPhone has better battery life and a more robust App store, but it suffers from a smaller screen, smaller camera resolution, no HDMI out, face talk only on wi-fi networks, and ...
