Projects on Steroids II

This project details a small & simple, but very powerful USB charger for your mp3 player, camera, cell phone, and just about any other gadget you can plug into a USB port to charge!

The USB charger that runs off 3 volt Boost regulator. this one is a twist with two "D" Cell. Does not work with Apple i"whatever", for apple you need to set 2 voltages on D+ and D- pins this will set your charge rate.
