‘DSD-08AS’ is an electromechanical sound installation. 24 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. Soon after the beginning by applying electricity to the installation, the resulting rhythm of solenoid bolts hitting metal balls starts shifting and recreates it self over and over again in endless possibilities. There are several factors influencing the sound beside the mechanical inaccuracy of the the solenoids - the friction of the balls on the rails, the characteristic of the wall, the installation is mounted on, the size of the space and the position of the spectator. At the end of a cycle the electricity gets cut and the balls rest in their last position. Leaving the spectator in a silent space where slowly the atmosphere sound fades in. Like in my previous works I have been experimenting with unconventional ways of producing sound by using devices and tools made for a different purpose. In this installation, these objects become new devices to produce unpredictable results.

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. This installation functions through the inaccuracy of the used solenoids and the malfunction that occurs when the circuits are getting closed between the metal balls and the heads of the solenoids. The outcome is an initially synchronous sequences that is running apart over time, until the end of a loop cycle and a reset.

The basic principle how the installation works is electricity, on and off - either electricity flows or is cut off. No additional components like sensors or microcontrollers are used. The title is a reference to the used material - the type designation of the solenoids that are used. The wall the installation is mounted on functions as a resonating body and influences the sound based on the material of the wall and space behind the wall. A solid concrete wall absorbs the sound compared to a drywall, where the hallow space behind creates an excellent resonance space to amplify the sound.

electricity: - 1x 230V CEE 7/7 8A (power outlet next to the installation on the floor) if 110V - details need to be discussed exhibition space: - wall for mounting the installation: min. 5,5 meters width and min. 2,8 meters height, it has to be possible to mount the modules with screws into the wall (wood or drywall) - preferred color: white - distance: There should be a minimum of 5 meters distance to view the installation. - sound: The sound is a big aspect of this installation and needs to be considered in placing it into a space with other works. The installation produces a medium high volume of sound, thereby the audience experience is influenced by other works in the same or next room if not acoustic separated and vice versa. - If possible: comfortable sitting possibility for the spectators at 7 meter distance from the installation, e.g. museum bench fitting the exhibition architecture light: - 3 spot lights pointing the installation tools for installing (need to be provided): - screws (flat head) and screw anchors 50 pieces ( type - depending on the wall material) - electric drill and drill bits - depending on wall material - water level (100cm) - ladder set-up: the set-up time is minimum 2 days (depending on the wall material), the artist or an assistant has to be present for the installing of the work. maintenance: the installation needs continually maintenance during the exhibition hours: cleaning of the metal rails, balls and contacts.
