Qtouch Capacitive Sensor
Found some cheap capacitive touch sensors online ($1.97, functionality similar to theremins. page 288 of Physical Computing). I'm not sure how sensitive it is (listed as: extremely sensitive). Ideally I'd like it to operate like a theremin in that you can be fairly far away from it and get a change in capacitance. Perry seems to think that the size of the sensor you attach to circuit may affect the range. Going to order some and experiment to see. I'm thinking about creating an array of them and imbedding them in a sculpture/instrument. Would like to couple them with force sensors as well, but those are more expensive:
SlideLong (strip force sensor) $32
SlideWide (wacom like pad, 1 dimensional, can be 2d if you sandwich one on top of the other and rotate 90 degrees) $64.
