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.

MotorBEAST
Motorized fader console for BEAST, the Birmingham ElectroAcoustic Sound Theatre.
Emphasis on compact size (32 faders within 81x22cm) and resolution (16-bit ADCs, 12-bit positioning accuracy).
In 2012 clones were sold to MAAST, Kent and De Montfort, Leicester.
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.
Matrix Guitar
Custom gluion code for Warren Cross’ Matrix Guitar
Pneumatic Sound Field
Modified gluion for sample-accurate control of pneumatic valves. Driven by an ADAT line with 64 dual-channel outputs.
Twister
Contracting work for twosuns, a Berlin multi-media company. Twister is part of the sound subsystem of enclued, an interactive multi-media development environment. Initially a multi-channel soundcard with embedded spatialization functionality, which was later moved to the host PC.
SoundLab
Early predecessor of the gluiph. A small 56k module to fit inside the SensorLab.
quaDAC
A four-channel audio converter for the NeXT cube and the ispw (i.e. the IRCAM signal processing workstation).
This started as a hack with a couple of evaluation boards and some blobs of glue logic. With help from Atau Tanaka, and the original design by CCRMA.The second version though had its own board and features analog inputs as well as AES/EBU and S/PDIF. It was designed around an FPGA (by Xilinx) to allow for easy modification in the event that other customers might want to run it off a different machine. These days, however, with tons of multi-channel soundcards available it’s hard to thrill people with quadro…
