Ipod touch 4g charger from AA's?
Hey all- does anyone know of an ipod charger that runs on AA's that can charge an ipod touch 4g? I am going on a trip soon (1 week) and would like to try to make a backup battery for my touch. I have most materials that would be used for this- a variety of caps, 7805's, a few resistors, pretty much everything except a battery holder. I can also head to radioshack (maybe in a couple days if I need to get anything). Anyone know of anything?
