Can someone help me plan a solar USB charger(5V)? Answered
I have three solar panels that I would like to use for a solar USB charging kit. I don't know how they should be put together. Two are 5V panels at 100 and 200MA each, and the third is 5.5V I believe at 320MA. The third panel came as part of a kit from Brown Dog Gadgets but I accidentally soldered two points together that weren't supposed to connect (they were too close together :( and the circuit started smoking). I'd like to make something that could charge my iPod touch 4th gen as well as other USB devices.
