"PJRC High Capacity MP3 Player Circuit Board"[http://www.pjrc.com/tech/mp3/]
 
 
a stand alone MP3 player,
 
uses FAT32 IDE hard drives
 
(it buffers songs in a 72 pin SIMM DRAM so the hard drive is in sleep mode most of the time,
 
improving battery lifetime),
 
a 24 bit DAC,
 
a Xilinx FPGA (one of the few that fits in a through-hole socket) (for interfacing to the SIMM DRAM),
 
the STA013 MP3 decoder chip,
 
a power supply designed to cope with the transients of automobile "12 V" power,
 
a 80C51-based microcontroller running a program in external flash memory chip,
 
etc.
 
 
"The firmware source code is available under the terms of the GNU General Public License (GPL).
 
...
 
The entire circuit board schematic is published, as well as schematics for the circuitry implemented by the FPGA."
