Sakura - The World’s Simplest Open Source DIY MP3 player!
For around $30 in parts and a good amount of patience, you can have a completely open source and hackable mp3 player ready to go. It can be modified to accept serial commands, be embedded in an art project, used as the voice of your next smart talking robo-sidekick, or filled with music and used as is. Put in whatever size card you want, up to the theoretical limit of the MMC format.
- shuffle mode
- basic track navigation
- volume control
- FAT32 support
- fragmented file support
- an unlimited number of files on the root directory
- high quality playback.
Files at 256Kbps can be played without a hitch. Variable bitrate files are supported with peaks up to 320Kbps. WAV files are also supported, but they have to be less than CD quality unless you put a faster oscillator in the pic.
