Behind the screen of Bum Tschack Wippe - a seesaw that makes music. @see vimeo.com/6178203 for people enjoying the installation.
What you see:
Me installing the sound unit for the seesaw; Attaching the sensor (Arduino + Accelerometer in an aluminium box with hook-and-loop tape); Calibrating the analysis software.
The software with big moving yellow bars is called Influquencer. A sequencer that turns OSC inputs into midi output. Visit the first flickr image below for detailed notes on the interface.
The sound unit (hardware + software) is build for mobile use on other playgrounds and playground equipment.
