How To: Build a Wireless Energy Transfer Array to Power Light Bulbs Without Plugging Them In

In this article, I'll show you how to built a Wireless Transfer of Energy Transmitter. Simply put, this device will send electricity to a florescent light bulb and light it up, from up to three feet. The idea originally (at least, prominently) came from Nikola Tesla (read more about this amazing inventor here), who used his Tesla coils to transfer wireless energy to light bulbs in demonstrations (photo below). However, the circuit described in this article consists of a flyback transformer, n...

How to Play Dead Space 2: Achievement & Trophy Guide

It's currently 2011, but when you fire up your game console, put your hands on the controller and play the new Dead Space 2 video game, you're warped into the future— into the year 2511— just 3 years after the events that took place in the first Dead Space.

News: The Stupid Orchestra

How can an orchestra be stupid, one may ask? Well, when musically measuring a toaster next to a cello, one device certainly comes across as inherently… dumber. Think 200 vintage vacuum cleaners, blenders and washing machines assembled into a whirling, ringing, humming cacophony of daily function. It's not exactly music to the ears, but a kind of robotic harmony is formed.

How To: High Voltage Happiness? How to Make a Negative Ion Generator

In this article, I'll show you how to build a simplistic circuit to generate negative ions. Negative ions have been known to contribute to fresher air, happier mood, and general health benefits. However, they also look amazing in the dark (check out the photos below, purple plasma is amazing!). And if all else fails, they make a cool nightlight. If you've ever been around a Tesla coil, cathode ray tube TV or sometimes even on a trampoline, you've probably noticed that smell; the smell of "sta...

News: The Revolution of the Hacked Kinect, Part 1: Teaching Robots & the Blind to See

In 2007, Nintendo introduced the world to motion control video games with the Wii. Microsoft and Sony built on Nintendo's phenomenal success and released their own motion control products for the XBox 360 and Playstation 3 late in 2010: the Kinect and the Move. The Move is basically an improved Wiimote that looks like a sci-fi Harry Potter wand, but the Kinect just might be the most important video game peripheral of all time.

How To: Build & Hide a Campfire from Your Enemies — The Dakota Fire Pit

Fire.  It’s everywhere— always has been.  From the Ordovician Period where the first fossil record of fire appears to the present day everyday uses of the Holocene.  Today, we abundantly create flames (intentionally or unintentionally) in power plants, extractive metallurgy, incendiary bombs, combustion engines, controlled burns, wildfires, fireplaces, campfires, grills, candles, gas stoves and ovens, matches, cigarettes, and the list goes on... Yet with our societies' prodigal use of fire, t...
