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...

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 ...

How To: How A Computer Works

Many folks seem to treat their computers as a sort of mysterious alien technology that only the shamans of the IT Department can comprehend. You might have gotten it into your head that you're just not good at computers and will never understand them. On the contrary, getting a basic grasp on all the amazing stuff inside your computer doesn't require you to be a technological genius. Most people will never have a need or desire to open up their computer and poke around. But it's your machine....

How To: Hate Ugly-Looking Power Strips? Make This Sleek DIY Power Outlet Box for Your Desktop

One of the biggest downsides to having so many gadgets is that you never seem to have enough outlets to power them all. Most of us have a power strip or two to solve this problem, but Instructables user dlewisa wanted something a little nicer looking, so he built this DIY desktop power outlet. For the housing, dlewisa put together a small wooden box using a nail gun and wood glue. He used a sander to round off the corners, then filled in the gaps with wood filler and painted it. You could als...

How To: Create a PCB Etchant That Automatically Improves After Each Use

Etching your own circuit boards is tons of fun, but etching requires strong chemicals to dissolve the copper plating on blank circuit boards. The normal ferric chloride solution works well, but can be expensive and leaves permanent stains. Luckily, we can whip up our own etchant at home with everyday chemicals! Better yet, our new etchant will turn an eerie green color rather than the dull brown of ferric chloride.

How To: Create Practically Anything, Part 2: 3D Models in SketchUp

Creating any object you want is as simple as point and click if you have a 3D printer at home. If you don't have one handy, there are a few companies that offer printing services online. But to help services realize your design in extruded plastic, you have to make a 3D computer model for the printing machine. For beginners, the free Google SketchUp application is the best choice of software. Using only a few tool bar buttons and a scroll wheel computer mouse, you can model literally any obje...

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 Simpsons Family Gets Scrabbled!

My JO was watching The Simpsons on FOX the other day, like she wholeheartedly does every evening, and I joined her, much like I always do— though I must admit, I'm not as obsessed with the cartoon family as much as she is. Just like she isn't as obsessed with SCRABBLE as I am.
