The DIY MP3 Player. Pfaff, iPods? Sissy toys. Real men put together their own open design MP3 player. It may not look too purty, but it’ll play music all right. You need more? Oh and the main module costs a whopping $19.99. Yeah.
The main goal of this project is to create an open design for a portable MP3 player, in both hardware and software. The secondary goal of this project is to make it as simple to construct, and as cheap, as possible. The design is based around the AVR Butterfly from Atmel.
