One Laser + Hourglass + Circuits = Crazy Gijs Noise Generator

Now, here’s the way to do an analog noise generator oscillator: use grains of sand. As falling sand interrupts the flow of a laser to a light-sensitive sensor (a photodetector), the circuit produces random oscillations of sound. It’s the latest brilliant creation of mad Dutch scientist Gijs Gieskes, the industrial designer-turned-musician whose inventions often center on some physical and mechanical apparatus. Just for good measure, the project is mounted to a clear frame so it can be fit to a Eurorack modular setup. You can try building this yourself; as with all of Gijs’ projects, the circuit is freely available …

Gijs’ Servo Sequencer, Opto-Mechanical Music, Events in Breda + Eindhoven

The Servo Sequencer with its hypnotic-looking optical disc. Photo courtesy Gijs Gieskes. 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 …

Circuit-Bent Browser: Webcrawlers Make Live Visuals

Hacker extraorindaire Gijs Gieskes has turned your local web browser into an insane, glitched-out audiovisual instrument. He writes: Here is a new project, it involves using webcrawlers to make live visuals with music. <http://gieskes.nl/browserjockey/>. works quite o.k. The music is some of my old recordings on mini disc’s i still had.. mostly 2000 till 2003 i think, its just to show the scripts in action. Some more description is here <http://gieskes.nl/?archive=browser-jockey> Flickr? YouTube? Explode? If you could actually circuit-bend web browser code, the results might look something like this. Think of it as a software short-circuit. (The famous example of …
