My latest controller. I'll premiere it this Friday (23 July 2010) at the bring-your-own-laptop event at staalplaat. It includes a light sensor, 2 touch sensors, some big switches and lots of knobs for control. It is also wireless and runs off either a 9V battery or a 9-14V wall adapter. The controller data is picked up by redWirelessMaster and is then read by the computer via a serial port.
Firmware, parts list and schematics attached below. A SuperCollider class for interpreting the data is also included.
Flickr photostream from the build process. I took out most of these beautiful old electronics and replaced it with my own circuit board. Only kept the front end interface with the nice knobs.

130122: SuperCollider GUI class updated and new help files and MIDI control (via a nanoKontroll).
2006 I fiddled with some simple drawing routines in SuperCollider. (swiki.hfbk-hamburg.de:8888/MusicTechnology/833). Now I've added matching (?) sound synthesis and some slight modifications to the drawing code. There are 7 parameters that are used to both generate the picture and the sound. Normally the parameters are randomised but it is possible to copy&paste a good sounding/looking set of parameters into the code to get the same drawing back.
I bought the klinkenstecker 3.5mm 4pol for €2,40 from Segor. The capsule microphone I had laying around. Sorry, no data or idea where I got it. The whole thing is very simple to build and the sound is totally all right. Now I can record into the iPod Touch and run apps like RjDj and SuperCollider with audio input.
For our recent installation at ISCM World New Music Days in Växjö (www.musicalfieldsforever.com/interactive-art/searching-voices/), I built a circuit for controlling 9x5m el-wire (electroluminescence). There are 9 channels in total and 3 inverters that are powering three 5meter cables each. TIC201d TRIACs are used for switching the 110V AC on/off, 9 led+LDR pairs (aka Vactrol) generates the control voltage for the TRIACs and wireless control for the whole thing is obtained with an ATmega8 and a pair of Nordic transceivers. SuperCollider is generating control data.
