MIDI Tart Music Organ

https://www.youtube.com/watch?v=Ezld7MQXM2U
Designed an organ over the Christmas break.
Fully 3D printed.
1kg of PLA, 60 hours printing.
MIDI controlled.
12 note chromatic.
MIDI controller from "look mum no computer".

The ventilator and the midicontroller each use their own supply.
I run the ventilator at 0.4A for that you need around 15.4V. At this supply I get around 30 mm of water column pressure.
The midicontrollerboard that drives the 6V solenoids is powered at 8V.
