So I soldered wires between my CC-wheels and a DB-15 (Joystick) connector for attaching to the soundcard.
The wiring diagram looks like this.
Did it work? Well, sort of. They are very unstable but work. It’s like there is some twitching in the pitch from time to time even though your not touching the wheel. It could be a dead center adjustment. I’ll figure the unstabillity out later but it worked.
I have glued these to the frontpanel and are waiting for the glue to dry.
