Does anybody know how to make a SD-card only type mp3 player with a line out?
I'm looking for a way to play mp3's on any audio equipment that accepts aux in or something. Doesn't need to have anything flashy, just a little box, bulletproof,good sound quality, that can handle SD cards (4GB support should be enough, but more is always better). Of course it will also need the basic buttons on it for play/stop/prev/next.
How hard/expensive is this to make and how to do the actual mp3 to audio conversion? (I have no experience with chip programming)
