Build Your Own MP3 Player


Yes, this is serious. Maybe you're into building your own hardware, or you just can't give Steve Jobs $400 for that iPod to listen to your music. Whatever the reason, just because you put a hard drive into a case, this project is not for the faint of heart. Good luck if you decide to put this together.
This is small MP3 player. It's cheap and of excellent quality. An MMC has only seven pins and is currently the cheapest flash memory on the market! SD cards are now fully supported!
Powered by a single AAA (HR03) 1V2 Ni-Mh battery. Runs on a 18LF452 at 20 MhZ.

Up to 256 kBps bitrate at 44,1 kHz supported. VBR may peak at 320 kBps. ID3 v2.3 tags supported.

Full user control (volume, track, skip) with a Micro joystick.

Real Time display of bitrate, sampling rate, elapsed time, songnumber, ...

LCD contrast adjustable.

Voice Recording in PCM-format could be added later!
