AT THE BASEMENT
I'm a retired man, so I have a lot of time. At the basement of my home, since 2017, there is a pipe organ. The construction of this takes 3...4 weeks.
Look also my self made "Arduino Happy Birthday Machine" and my organ driven by the wiper motor of a car.
I don't know why. But it's pretty to build something. My organ is a combination of music, physics and electronics. The organ pipes come from Amsterdam, de wood comes grom the GAMMA and HUBO. The pallet electro magnets are bought in England (WICKS).
