If you’re like most people, you probably have a few chargers scattered around your home. But if you’re always on the go and need to keep your phone charged, a wireless induction charger can be a lifesaver. In this guide, we’ll show you how to make your own wireless induction charger using just a few simple supplies. First, you’ll need some materials: an induction coil, wire, and a power supply. You can find induction coils online or at your local hardware store. The coil should be about 18 inches long and have a diameter of about 1 inch. Next, connect the coil to the power supply by connecting the black wire to the negative terminal and the red wire to the positive terminal. Make sure that both wires are long enough so that they reach all corners of your charging station. Now it’s time to build your charging station! Start by placing some sturdy furniture on either side of the coil so that it’s stable. Then place pieces of wood or plastic on top of that to create a platform for your devices. You can also use small bricks or tiles if you have them lying around. Finally, place your devices on top of the charging station and plug in your power supply. You’re ready to start charging! ..


Courtesy of Instructables user Inducktion shares a very detailed tutorial on how to build a wireless power charger. He explains the impetus behind the project:

For what the project lacks for in miniaturization it more than makes up for with thoroughness. Hit up the link below to check the project out.

This transmitter works fantastic, and can run on pretty much any voltage above 12 volts, and below 24! It’s also extremely efficient (little power lost) and, it generates almost no interference. (one wireless power instructable used a square wave in the primary; Square waves have a lot of harmonics, and can cause havoc on computer systems, radios, and other sensitive electronics)

I’ve come to solve all of these problems!
