Try to find knobs that look like the ones on the BMW steering wheel, you'll tear your hair out. After a week of searching to no avail, I gave up. The guitar amp knobs are the best I could come up with.
If anyone knows where I can get good-looking knobs, please tell me.
Video is coming soon (I had a busy weekend). I should be able to put something up tonight.
Yes, I use Bourns rotary digital contacting encoders. They send quadrature code output, the U-HID interprets one button press for one direction and another button press for the other direction (which is exactly what you want ).
Adjusting roll bars, brake balance, etc. with the knobs will require some shenanigans with LFS scripts. I'm pretty sure it will work, I just haven't gotten around to it yet.
You should make a how to guide, with how you made all the buttons and LCD display. So we can make it too, and you could update it when ever you want with new functions you found and stuff. This is offcourse if you would want to share your secrets with the rest of the world
Yeah, I haven't identified anything yet that I don't think will work. It's just going to be a little gross writing a script to navigate the menus to change the brake bias or ARBs instead of exposing controls for increasing or decreasing them directly.
For anyone who's wondering about a tutorial, I haven't much time at all to work on it. I'd like to get one up sometime, but I can't speculate when that would happen. I'm more than happy to ask questions, though, so feel free to send me PMs.
Also, if anybody wants to buy one or if there are any venture capitalists among you, I'd love to hear from you.
This wheel uses a Leo Bodnar SLI-PRO and has 12 buttons, six 12-way switches, and two rotary encoders. Two of the switches control the display and one of the encoders controls brightness (as you'll see in the first video).
Mods, this thread would definitely be more appropriate in Hardware. I won't complain if you move it.
