[James Bellafaire] wanted a good looking old radio with a modern sound. Granted, you could hollow the case out and replace it with an iPod. Or you could convert the thing to an Internet radio. But where’s the fun in that?
[James] took a different approach. Part woodworking project, part Raspberry Pi project, and part microcontroller project, he wound up with a hard drive-based music player in a 1930’s case with knobs that control the playback.
Since the Pi isn’t great at reading potentiometers, [James] took at ATTiny85 and used it for that purpose. Coupled with a few hundred old jazz songs from the Internet archive that the Pi can read from a hard drive, and the old radio cranks out period-appropriate tunes again.
