This site belongs to an MIT student named Ladyada. The project is a very small MP3 player that can fit inside an Altoids mint can. She calls it the Minty MP3 player.

So for approx. $50, minimal total cost of $25 for parts, and $25 for a PCB, you can have your own MP3 player. This rates high on the geek factor. It's a pretty advanced project so if this is your first DIY, don't pick this as your first DIY project.

Firmware is available on the site, including the PCB layout in Eagle. (See my other post about PCB design software)
  • EagleCad format (free PCB layout program)
  • Version 1.1 (matching above) Firmware in PICC format (with HEX and ASM) for 20MHz 18(L)F452
  • Version "1.1" (but really V0.000001) Java software for uploading over serial port at 115Kbps
  • The Tiny Bootloader I use...it's quite nice...this is the HEX file I use for 20MHz and 19.2kbs communication. Its not necessary, but it is nice.
Minty MP3 Player. Shweeet!
