Intro: How to Make Mp3 Speaker Box From Cheap Radio Fm
I have cheap and litle mp3 player that can be heared with headphone. I also have cheap fm radio operated with 2 AA batteries. I combine both mp3 player and radio to make a compact mp3 speaker box operated with 2 AA batteries.
From radio, I take a speaker and a pcb. I just use the amplifier, so I eliminated the pcb to fit the new box. use the stereo jack and solder the L and R channel united to connect to the potensiometer in radio.
