So I put a broken laptop inside a gamepad shell, a d have two joy cons I wired up to the sides and am trying to solder the original gamepad thumbsticks to the 3rd party joy cons, the other buttons I have gotten to work just fine but the thumbsticks stump me, the closest I got is the side to side and upper range worki g but lower half still dead. Im not good at this stuff and just having fun with my project but any help is greatly appreciated
