Custom Fight Stick Woes


#1

Hello, I decided to make my own fight stick by modding a PC gamepad. However I have run into an odd problem. Whenever I hit down on the fight stick, left also registers.

Upon inspection I found that if I merely touched one of the wires connected to down then left would register. This makes absolutely no sense to me as how is it completing a circuit by just touching one control wire?

When I was wiring the controller up I tested each button individually and they all worked… it wasn’t till I hooked it up to my fightstick that this problem started happening. I suspected it could be the actual joystick itself so I disconnected the offending wires, and the problem persists.

If anyone has run into a similar problem and would have any advice I would greatly appreciate it.

Additionally the gamepad I used was this one http://www.newegg.com/Product/Product.aspx?Item=N82E16826127208 if it turns out the board is bad, would anyone recommend an alternate controller?

isn’t that pad non common ground?

What joystick are you using? if you are using a joystick with PCB that requires all the directions have a common, that could be the problem. Anyways if that PCB won’t do then there is always the trusty old Cthulhu PCB by Toodles.
