burning pipes the pneumatic orchestra

Air is blown trough elastic pipe into the hole, making sound dependend on the position of the can

movement of the cans is controlled by 9 independent servos connected to the arduino board while the sound is purely analogue– air pumped by 9 ordinary mattress pumps blows into the "whistles" at the top of plexiglass pipes. tone is modulated by the current position of the can.

lots of soldering, gluing, screwing, cutting and coding

video of the ‘orchestra’ playing, with some process documentation

Each can is controlled independently via servo motor. Cans are attached to the servo wheels by a fishing line.

Whole thing is illuminated by 9 lights situated under the supporting structure.

Air pipes hidden at the back of installation.

Servos and lots of wires 😉
