Anyone built the fair mouse @info_1 offers as a kit and had it work? Mine processes clicks left and right, sort of anyway. But moving the mouse makes the pointer "wiggle a bit" and that's about it, there's no actual "movement" as in a certain direction. Now I *did* have a lot of problems soldering the USB wires to the PCB but I am pretty sure I got that cleaned up properly. Only "short" I measured was between ground and shielding and APPARENTLY that's standard? Maybe not? Anything else I could have messed up? I did notice a small tab on the bottom of the sensor but the instructions didn't talk about it. Was I supposed to remove that? Was that some kind of "lens protector" that makes it so the sensor is not doing its job now? Anyone else got any helpful hints what to look at? #nagerit #fairmouse #fairit #fairityourself #soldering #noob
