My son has been playing Forza Horizon 6 on the PC. He plays it with a PS4 controller, so I modified one to include a 10k pot (potentiometer) as steering wheel replacing the left analog stick to improve steering.
I’m using a 10k pot which roughly matches the X axis of the analog stick. The wired resistors as seen on the board is an old modification to fix stick drift.
The hardest part of this was desoldering the left analog stick, had to add leaded solder first to make it easier.
The pot is replacing the cavity where the left analog stick used to be. I cut off the plastic top case for the left stick and drilled a hole to fit the pot, then glued it into place with epoxy.
The pot is soldered in where the X axis of the left analog stick used to be, also added two 4.7k resistors to emulate a centered Y axis stick.
This is the result; first prototype. My son has been testing the it for a while now and likes the improved control, but he wants a bigger knob for the pot so I will fix that.
