Voltavox is a PCB-based phonograph "badge"!
Made primarially from PCBs, you can take a tiny PCB record, place it on the platter, place the needle on the record, and a song begins to play! Put a different record on, and as expected, you'll get a different song.
Voltavox is based heavily on the Adafruit Audio FX Sound Board. Using arturo182's FlexyPins and some castellated edges on the record PCBs, each record selectively pulls a different control pin on the Audio FX board to ground, choosing a different track. Dropping the needle onto the record completes the circuit and starts playing the audio. The horn is also comprised of PCBs soldered edge-to-edge, with a small speaker inside.
