Hi - I have a slightly odd problem. I have a 3K pot that I'd like to have be more a 2K or 2.5K pot (not positive about the range just yet - but somewhere around 2-2.5K).
This reason for doing it is this: I recently acquired some hobby servos. Unlike the servos I've used before, they were limited to about 120 degrees of rotation (others I've used have been able to go about 190 degrees). I have confirmed that all the mechanics of the servo allow about 190 degrees of rotation. It's just that the control chip will only allow it to go about0-120 degrees. The control chip gets its position sensing from a pot (that can turn about 190 degrees) that is attached directly to the output shaft. Thus - it would be possible to trick the servo into going the full 180 degrees if I could multiply the resistance by about 2/3. (2/3 = 120/180).
Any ideas on how to do this? I should mention that it appears one of the outside leads of the pot, as would be expected, is entirely disconnected.
