Waldfl̦te Project РMIDI Pipe Organ

Some of the music that this creation can produce is wonderful! I love the clack clack of the solenoids working in rhythm.
Have a look at the build details here.

"The Waldflöte project is a MIDI retrofit to a 1890s Gray and Davison pipe organ located in the Forest Cafe in Edinburgh. It converts MIDI input into solenoid drive to directly press the keys on one of the manuals – there is no permanent modification to the organ. Members of Dorkbot Edinburgh have spent the last 7 months or so working on this and we’re pretty pleased with it. It was publicly announced at the Electron Club Open Day on 18th October 2008 in Glasgow."
