A Sonic Pi controlled Glockenspiel

I have created a Sonic Pi controlled Glockenspiel which runs on a Raspberry Pi3. It is controlled by means of a series of solenoids with Lego hammers, and interfaces to the Raspberry Pi GPIO pins.

Full constructional details, plus software are contained in an article which can be found here.

New mark II version with overhead hammers is here
