Capacitive Paint Controller by Jimmy Hughes

From Jimmy Hughes' website:

" I have been playing with Bare Conductive paint since it came out a little more than a year ago.
It’s great stuff – a heavy acrylic paint that can be used as a resistor, touch sensor, paintable wire – and I keep coming up with new uses for it. 
 This idea stemmed from wanting to utilize my modular synth in more of an installation setting than a performance music setting.

I think of this as a sort of “sonic self-portrait.” 
 Two 10″x 10″ canvasses painted yellow with my hand prints painted in conductive paint. 
 A small piece of copper tape is attached to the back of each canvas and connected to Arduino. 
Code on the Arduino turns the canvases into capacitive sensors and sends two channels of 0-5V PWM voltage out through RC filters into the modular synthesizer. In short: touch the painting, send modulations to the synthesizer."
