95 had wanted to use a string pot last year. The application was simple enough, keep track of how much of a telescoping arm had extended. The idea was that it made more sense to measure the distance the arm extended rather then measure the number of turns a gear made.

In the end, we couldn't find a string pot that met any of our criteria for size, output, price or availability. They just didn't seem to exist. Of course, the folks looking for them consisted of me and a mechanical engineer, neither of us qualified to know where to look or exactly what to look for. It seemed like they should be listed right near all the other kinds of pots with the same options for specifications. We considered making a string pot out of a pot string and such, but that seemed a little foolish.

They are just pots with a spring loaded string right? Why are they so expensive and difficult to find?

Maybe AndyMark should whip up some little adapter that can be stuck on a normal pot to turn it into a string pot.
