LM317T Voltage Regulator with Pass Transistor

Here is my second video with the full description of the circuit. And yes it does charge all iphones/ipads/ipods. Supplies needed: 5v voltage regulator, two 100 ohm resistors, switch, very thin wires, altoids tin, USB port, 9v battery dock, electrical tape, 9v battery.

This is a DIY solar powered USB charger with schematic that you can build to charge your ipod, blackberry, iphone, camera, or any other electronic device that you can plug into a USB port. There are 2 (in quantity) 5 volt solar panels connected in parallel to a 12000 uF capacitor. The positive is then connected to pin 1 of the voltage regulator (low dropout), pin 2 connected to ground. Pin 3 and ground are then connected in parallel with a 470uF cap, which is then connected to the USB port.
