For those wondering like I was, mousewheels typically use optical or magnetic rotary encoders. However some do actually use potentiometers. I'm pretty sure the one pictured is an encoder though; all of the potentiometer based mousewheels I can find are way more bulky than that.
Edit: Damn it Lemmy. Fix your sorting so I'm not accidentally commenting on 4 day old posts.
Honestly I kinda like the vibe of genuine necroing going on here. Is it a few hours old? A few days? 3 years? Who cares?
Wait, some of them actually use potentiometers??
I’ve never seen that and that seems wildly stupid as a mechanism. Far too flawed in comparison to an optical wheel and sensor, and it’s not like the optical sensor is expensive,
uff... confidentially wrong like ChatGPT
iFixit does this kind of content better and shows you how to get your mouse to work again.
