Hi, I have been trying to build an mp3 player for about 3 months or so now. I had it working on a breadboard and it worked! I have now tried to transfer it to strip board, and I just cant find my error. I have replaced my mp3 decoder chip, once, blew an sd card, now replaced that, and now i think its the power supply. has anyone got any suggestions because i;m about to smash it!
