Chuck-
Do you know where one can get those Force Sensing Resistors
commercially Those look like the best system to use. No worry about
stray capacitance and I'm sure the touch response is much more
controllable. The outputs could easily be connected to the Serge
"programmer" circuit to add that functionality. They look cooler too.
