My dog ate my Dualshock 3 wireless controller for PS3, so I salvaged the joysticks. They are made by ALPS. They appear to be similar to their RKJXV1224005 joystick, except that each potentiometer has 4 leads instead of 3. I have tried measuring the resistance between the leads to figure out which one is the wiper, but my tests were inconclusive. Do any of you have a datasheet for these joysticks?
