What makes this work is that the conductive foam is comprised of tiny air pockets.· As the conductive foam is compressed, you increase the surface area between adjacent air pockets.· This effectively is like adding tiny resistors in parallel with one another in proportion to the amount of applied pressure. ·
ah you beat me to it Beau!! Nice instructable that Phil did.. Good to see that here so I don't have to repeat it..
Plus the best way to read it is to use your RCTIME circuit and replace the variable resistor with the touch pad leads and all the programming is the same for reading the voltage drop out of the cap.

If a robot has a screw then it must be romoved and hacked into..
