Here is the “Minty mp3″ player. Limor from ladyada.net designed her own mp3 player that runs off of a CF card. She placed all of her components into an Altoids can.
This player uses a STA013 MP3 decoder chip, and a PIC18LF452 microcontroller to access all of the file structure. This is not a project for the faint of heart, but is definately cool. It uses all surface mount hardware, so is not easy to solder, and you have to have a custom made PCB in order to make it work.
Go read the overview here.
Limor writes:…The MintyMP3 hardware is a standard mix of high power 8-bit microcontroller and ASICs. A single PIC18LF452 running at 20mhz (For v2 the crystal has been changed to 29.4912MHz) with the minty firmware talks to the CF flash card, navigating the FAT16 file system and loading mp3 files, then sending the data to the STA013 MP3 decoder chip. The STA013 decodes MP3 into digital audio which is then converted to linelevel audio by the CS4340 DAC. There is also a MAX576 boost regulator (optional if running from a LiIon battery) and a MAX2606 FM transmitter (optional)…

Thanks Shane for catching that mistake. (I wrote the article during class:) )
I apologize for that. Serves me right for not paying attention to class. Whoops.
