Is there such a thing as a "resistor pad"? I need a way to select a point that represents 2 resistor values. Basically I want to combine the use of two pot's into one "pad". The x axis represents one of the pots and the y axis another pot.
Not sure if they make such a thing but maybe if it was just a sensor for x-y position and it programmed two active resistors(but I need high voltage).
Analog resistive touchscreens work like this, sort of. Presumably the touchpads on laptops do too, although I guess they could be using other techniques (capacitive perhaps).
Can you just use an analog joystick somehow?

Warm up the time machine and set it for 1985:
You're not plugging my Koala Pad to no high voltages! Besides it's breaking, the top plastic film on the pad is bubbling and peeling off. (SUCKS)
So what's wrong with a laptop's touch pad and then somehow get this information to a MOSFET (your "active resistors")?
Are you sure he doesn't mean an L-pad or T-pad?
