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.
