[...] this type of joystick is really weird and like nothing ive hacked before. I've posted some pics of it.
At a glance, i think it is a magnetic proximity sensor of some type that has two poles for x and y. The circuitry must be some type of an amplifier. But i still can figure out what the green wire does. Any thoughts?
The coil probably... doesn't oscillate, there is no need of oscillation since the movement is produced by the joystick...The position of the ball, interferes with the flux of the magnetic field that the coil produces, and there should behall effect sensors at the button to measure this change...
The green wire should be there for either activation or calibration...[...]I suspect it's an activation wire, cause you need power to maintain constantly the magnetic field...
Does the movement feel smooth like an analog stick or is it click-click?
Just out of curiosity, is it bad having analog input into the axon II close to 5v? I know alot of devices are more around 2v to 4v range.
I've been looking all over for somewhere to scavenge or even buy that type of joystick.
