Hey guys, I'm new to the forum. I've come because I have a problem that I'm having trouble with. Basically I'm trying to make a servo, pretty much from scratch for a bigger project I'm working on. Overall it works well. However, after a few hours the potentiometer starts to wear out, and the signal gets really messy. At first I put the potentiometer at the end of the rotor shaft. Here's a video:

So, my next idea was to connect the potentiometer to the shaft via a gear so that the potentiometer wasn't exposed to any unnecessary force.

However, I get the same problem. I left it to run for a few hours to test it, but the potentiometer wears out. Admittedly, I don't have any experience with pre-made servos, but surely they don't wear out after a few hours of use? Is there a special type of potentiometer that I need to be using? What am I missing?
