This one definitely needs a bit more work.... Arduino powers 6 solenoids via ULN2803 transistor array IC. Lego used for construction but the electrics/electronics are not Lego parts. My aim was to used wine glasses tuned with water to play notes received via MIDI, but I am thinking a selection of different percussion sounds might be better
