How to make a steering wheel?

I'm trying to make my own steering wheel for GP2. I use the F1GP 1 to test it. I use 100K pot for steering, 50k accelerator, 50k brakes, 2 buttons for shifting. I put it together, but its not working like it should. The steering is OK, but the other two pots dont work, so I cannot calibrate it for testing. What's wrong? I wired these: G1,G2,... means gameport pins G1 - 100k pot - G3 G6 - 50k - 50k - G1 G2 - button - G1 G7 - button - G1 Do I need to connect something to thr ground G4 or G5? Please help, I'm stuck.

Look at http://www.oz.net/~wottenad/wheel.htm for complete directions. I know they work because I drive with a homemade wheel.

The buttons are wired wrong. Using your notation, they should be: G2 - button -G4 G7 - button - G4 Also the 50k pots should be connected in series and "inversely" to each other... See above Regards, Pekka > Akos

Hi, Use 200k pot u'll have more precision.
