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.

New project: eMotion
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.
Sun Run Sun
Small modules to generate sound based on location.
Unna Unit
128 servos and 3 LEDs controlled by two gluions. The latter don’t act as interfaces like usual but run a custom FPGA configuration that implements the complete behaviour model. No additional computer involved.
G-Player 4
What’s the sound of a giant turntable needle scratching across the earth’s surface? Find out by listening to the G-Player4 where satellites are tracked in realtime to mark a path across a world-wide topography. Data (altitude samples) from the SRTM Space Shuttle mission (2000) is interpreted 1:1 as audio data (amplitude samples).

An egg-shaped robot without limbs – but with attitude…
Mehta Trumpet
Virtual Mutes for a trumpet with an integrated DSP system.
SKRUB
A novel keyboard with linear sensing keys and an array of trackpads.
ETD
Contracting work for mtronix, a Berlin company that specializes in precision measurement instruments. ETD is short for Eye Tracking Device, although, to be more precise, it’s actually the pupil that’s being tracked. The technology is being used for LASIK as well as for medical research on the vestibulear system and how our eyes can contribute to our sense of balance. In fact, the system has made it up to the International Space Station (ISS) where these effects are researched in zero-gravity. ETD is built around the same processor as the gluiph, the TriMedia.
mpd502
Contracting work for mtronix, a Berlin company that specializes in precision measurement instruments. In mpd502 ‘pd’ is for ‘partial discharge’ which equates to energy lost along a power line. To measure this is crucial in determining the condition of the power system with the aim of being able to replace it just before it fails. mpd502 is built around the same processor as the gluiph, the TriMedia.
