I'm working on a custom project that involves potentiometers and picture adjustments on the monitor they are connected to.
To determine whether or not the potentiometers I need exist or if I need to build them, I need to resolve two questions and the possible issues they bring up.
1) This may seem like a crazy question, but are there low-friction potentiometers? (I'm referring to the physical friction incorporated into the pot to retard motion).
The reason I ask is because I guesstimate that in an extreme case, I'd need a potentiometer's knob/slide to rotate/travel it's full length 100 times in a single day. (Though in reality there probably wouldn't be that many cycles in a month).
This brings me to the second question.
2) Can a pot with a knob/slide that travels a distance of only one inch be adequate to cover the extremes for image parameters like Brightness, Contrast, Horizontal size, Horizontal position, Vertical size, & Vertical position?
To clarify my goal. I want to be able to quickly establish and lock in all six settings via mechanical means.
Springs will keep the knobs/slides at one side of their range, and when I need the correct settings, a plunger will ensure accurate re-positioning of the knobs/slides.
Thanks.
