Wendell Kapustiak built a modern Pipe Organ. Modern in the sense that naturally, it’s computer controlled. The air is supplied by a modified server cooling fan. The keys are played by an Arduino. And the songs are chosen by a web interfaced run on a Rasberry Pi.
It is pretty neat, I will give him that. I do like that he used wood for the pipes. The PVC pipes that lead to the valves though look horrible, that’s just like my opinion though. Overall, the entire thing is better than something I could build. I like it.
If that’s not enough Organ Pipes for you, you can head over to the National Monument in Arizona – no relation.
