Re: CHEAP or EASY String Pots (source, or fabbed)
How about using a spring tape measure and a simple photo resistor.
Paint the tape measure white...put your marks on it...use the photo resistor to "see the marks" ... count them.... process.
You will have to figure out how to tell the difference from going up and going down.... but that is doable too...
