Chuck,

I cannot help you with the pads, but when you say you put a pot
"inline", exactly how did you connect it?  You need to put the pot
across the pad, with the wiper and one end of the pad going to the
module.  Try something like 100k.

Mind you, if the TP100 doesn't work well, with its built in pot, then
I am a bit puzzled.

Maybe it is a polarity problem.  Try reversing the connections.

Keith.
