I spray-painted a cheap mouse that came with my laptop (it looks messy but in a good way?), and the left/right clicks miraculously worked after a bit of work (the left clicks is actually a bit dampened now, making it quieter!)

However, I think the optical sensor is borked. The mouse can click but it can’t move the cursor.

I’m thinking something like a bluetooth motion tracker that moves your cursor could work if I mounted it on the mouse, but does something like that even exist? I searched online and it doesn’t seem to be a thing. Maybe I have to DIY it a bit by buying a bluetooth motion tracker and using a program that makes it so that is moves the cursor?
