Spinning ping pong balls around 2 axes. Intricate patterns turn into concentric circles. High speed, high precision stepper motors with custom drivers controlled by FPGAs solving 5th-order equations in realtime, with a focus on event timing. Also filmed with cameras to be presented on a series of monitors.
Modular multi-channel motor controller for Julien Maire’s installation “Inverted Cone”
Second prototype, now complete with DC-DC converter and OpAmps for GSR and the optical pulse signal. The board matches the size of the Lantronix Matchport.
Decided to base the sensor system on Cypress’ PSoC architecture to explore the possibilities regarding its configurable analog subsystem. For now I’m using it to control the gain of the second stage GSR amplification.
Regarding wireless transmission we settled on WLAN and chose a Matchport module from Lantronix.
The cables you see in the picture clip onto standard electrodes.
The eMotion project aims to analyse the experience of museum visitors by tracking their position as well as biometric parameters.
My contribution will be a wireless GSR sensor to measure skin resistance and heart rate, while tracking will be accomplished by ubisense UWB tags.
The team includes psychologists, sociologists, researchers in art theory and visitor studies, musicians, artists, programmers, and designers.
