USB mp3 player kit

This type of ready-made MP3-FM kits are easily available in the market. The kit consists of one main board, one connector wire, one USB socket+wire, one remote with battery. ‘Amco’ is a reputed brand in manufacturing these boards. These boards have a 3.5 digit display for displaying song#, equalizer settings, FM frequency etc… These kits have stereo decoded output, just need to attach a stereo amplifier. These kits costs about 140-150/- only(as of 10/2010).USB mp3 kit

But If you are going to use remote, you must buy a extra IR sensor(about 12/-).
If you don’t have +5V regulated supply, you must create it using regulator IC LM7805 or 78L05.
