I have an idea for an instructable but I don't know where to start...
I recently bought an ilo mp3 player because
A) I'm cheap
B) I don't need 30gb+ of space... my songs barely take up 2-3gb
Anyway, it runs on a single AAA battery which is nice because it keeps the size/weight down but it's inconveniant to have to cart batteries around at all times :/ What I'm wondering is would it be possible to build some sort of AC adaptor that would connect to the battery holder? If so, what sorts of materials would I need?
