It’s been a while since I made a post here as I’ve been a little busy working on my new venture but I’m going to try and get back to it again. I’ve been messing around with some cool projects from the Pololu robot, to wireless power, to a wireless network exploit station built around the raspberry pi.

Anyway, some time ago, I became interested in wireless power. I don’t know a huge amount about electronic theory, but thought I’d give it a go. The circuit is really simple and really really REALLY inefficient. I use a signal generator to drive a high power transistor at about 10kHz square wave and then have 24VDC pulsed through the coil. The receiver is just a coil with a noisy weak AC current and some LEDs. I can increase efficiency slightly using a capacitor.

Of course, there are some far better circuits out there like or but this was just a quick hacked together test without going too much into the electronic theory of it. Here’s some pics..
