I started this project in 2014 when the Finnish artists´ association Muu ry commissioned a new sound machine from me for their sound art bank project. Since then I have steadily developed this project further. The SOUND DISK MACHINE is a photoelectronic, analog instrument that converts light into sound and can be played using any kind of light source. Even non-visible light, such as infrared light, can be made audible with this instrument. It consists of disks with distinct hole pattern, phototransistor circuits, 12V DC computer fans, analog filters, 6V miniature lamps and a self-made controller box. The disks are screwed onto the computer fans and the instrument's sonic outcome depends on the fans' speed of rotation, the disks' distinct hole patterns, the respective light sources and the light's angle of entry. With the current version 5 disks can be played at a time. The SOUND DISK MACHINE premiered in October 2014 at the International Performance Art Festival Amorph!14 in Helsinki. This art project is inspired by Evgeny Sholpo's "Variophone" instrument and has been realized with the kind support of Muu ry, Bernhard Sturm (ZKM Karlsruhe) and Janne Virkkunen.
