I am working on a project where I used a hollow pipe whose one end has a circuit board so that the wires will go through the pipe to the other end completing the connections. That pipe has to be rotatable, too. Rotation speed will not be too high, it will be minimal as in a steering wheel and it won't be rotated in only single direction. The problem is that it will result in wires being twisted and broken.
In short : I have an old gaming controller and I am turning into a steering wheel. I have other things designed and was thinking of integratimg afew buttons in the middle of the steering wheel.
I googled and found about slip rings, but I will appreciate if I get other alternative methods and if possible some DIYs.
Gamepad used: Quantum QHMPL QHM7468 USB game pad.
When opened, this gamepad has one main circuit board, two triggers (extendable by wires,) one joystick (two integrated) (extendable by wires.)
I have used the triggers as pedals, left the joystick for future use, used a spare mouse (optical sensor) at the end of steering wheel to get signals and convert input signals of mouse to joystick signals using a software.
Now I have the main circuit board left which I want to add on top of the steering wheel for more controls.
Main circuit board has four connecting wires, and from that, there originates 10 wires , 4 for joystick, 3 each for a trigger.
You can also tell a way to stop rotation of wheel after some specific angle, example - consider the wheel in initial position so that it can rotate about 480 degrees in both the direction after that it restricts motion (like some barrier inside the arrangement), as wire twisting problem will be only if the user rotates the wheel too much. If the motion will be restricted the wire will be experience much stress.
