DSD-08AS / Stefan Tiefengraber (AT)
DSD-08AS is a kinetic sound installation. Multiple modules - each consists of two solenoids, a metal rail and a metal ball - are building a self triggering system where the metal ball functions as conductor between the rail and the solenoids. The ball is closing the circuit and electricity is applied to the solenoid that is pushing in the same moment the ball back to the opposite side and thereby is cutting it self from the electric flow. This results in an interplay between the two solenoids and multiple loops with different time delays.
