I would like to make a touch sensor pad simliar to this : http://mondo-technology.com/pcpad.html

What I'm not sure of, is how to arrange the resistor/capacitor so that the person touching the sensor pad will change the RC value.

    Ktekx -

    If you don't feel like re-inventing the wheel, Qprox has some excellent capacitive touch sensors:

    Thanks, Bruce, I think that's just what I'm looking for.


    The qprox "Wheel & Slider" are pretty neat, I guess that's what the ipods use?
