penn station posted:For comparison you could do a test with a regular 10K pot. It is not critical to match the exact positions of these readings, only need enough points to draw curve similar to the one above.
Cam: I could get readings from a 10k pot. That would give a good x value. But the positioning would be ballpark and not very good for a y value. That's if I am understanding what you are proposing.
I have some other ideas. Let me try a few changes. I'll at least give you guys some more to look at.
