Are there pots that are completely circular? By this I mean that you can turn the shaft in one direction (or the other) continuously, jumping from the high end to the low end instantly? If so, what term is used to differentiate these kinds of pots from normal pots, and where might I find them?

Well, I know that the volume dial on my stereo system is like that, so there might be...

Nice signature, by the way...it seems familiar... ^_~

Mebbe you could modify a normal pot. Like, grind out the stopping post thing on the knob.

I don't think normal pots have a resistor that goes the full 360 deg. I suppose I could go in and mod it so I could turn the shaft all the way through, but then there would be a large deadspot on the low end. that wouldn't work very well for what I want to use it for.

Just wondering, what are you trying to use it for?
And to help answer your question, I will ask my EET brother if he knows or has any.

If you know what EET stands for, good for you. Now become one.

After you grind out the stopper, fill the dead space with solder, or something else conductive that can't move.

Same problem, there will be an area where the resistance doesn't change when the nob is turned.

If you must know, its an attempt to create a Driving controler work alike. Actually, it doesn't work the way the Atari Driving controler works, but rather the way Stelladaptor supporting programs expect it to.

There are other ways to do this (using fixed resistance values, for instance), but I thought this might be easier if I could find the right kind of pot.
