In the latest example of kinetic, sound-producing sculpture, an Arduino-controlled organ of moving cans makes eerie, beautiful descending noises. Jakub Koźniewski, a member of the panGenerator collective, sends in details of that group’s work, sponsored in this case by the stuff in the cans:

Kinetic audiovisual installation for burn
displayed during burn Selector Festival 2011

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

Worth viewing as it sounds really terrific; I’d love to hear it in person. The additional music bed is nice, as well: it’s Krzysztof Zimmermann, from the label Few Quiet People.

Thanks, Jakub!

Artists Gijs Gieskes’ sequencers are almost like physical, mechanical software, an expression of musical structure in object form. As such, even as they make strange sounds, they become musical sculpture. His latest Servo Sequencer combines optical and mechanical process, as frequency circles spin on a turntable and tone arms float above them.

The Servo Sequencer is built for exhibition use – meaning, yes, he’s brave enough to let you play with this contraption. Sequence the arms using buttons, then adjust the volume mix and placement of each arm using the joystick.

This project is unusually well-documented. Gijs provides complete specs, the script that controls the arms, and even a little web app that generates those lovely patterns.

But for those of you near the Netherlands, you should go check this out in person. Updated: The piece will be part of an exhibition in Breda through August 23, with multiple opening events featuring local artists from Eindhoven and Breda, plus live performances and concerts including Gijs and his talented brethren and neighbors.

Here & There Exhibition, mu.nl [Info in English]

The events:
Opening Part 1:
KOP, Breda
Thursday 25/06 08.00 pm

MU, Eindhoven
Friday 26/06 08.00 pm

(It’s a bit confusing as the events swap between Breda and Eindhoven — there’s a second opening Saturday July 25. Gijs explains “the first [opening] is in breda (thursday), then a day later (friday) in eindhoven, where my machine will be. and then a month later its the other way around.”)

You know, Breda. Like, right … here. We’ve got a number of readers in the area (whom I suspect know more or less exactly where this is); let us know if you make it!
