Miniature, portable build of Wurlitzer’s elusive keyboard teaching tool.

I am building a replica of Wurlirtzer’s Key Note Visualizer. It’s a simple and beautiful concept: play notes on a keyboard, and watch them light up on the display. There isn’t much info out there about this device, but I gather that it was originally designed as a tool for piano teachers to show a class of students what they were playing in real time. It’s unclear how the original visualizer connected to the Wurlitzer keyboards, but my build will work with any MIDI-enabled device. It will be battery powered and will communicate via Bluetooth, making it completely wireless.”
