el-wire

for our recent installation at iscm world new music days in växjö (www.musicalfieldsforever.com/searching_voices_conc.html), 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 the control data.
