Well after having trouble with getting it to work, so I gave up on it till now. Got rid of the shocks and springs.
I went with foam for now its alot better, but some kind of rubber would be even better. Ill be looking for some rubber bushings or something. I also shortened the throw that also made it better. Still running everything at my computer desk till I make a cockpit.
Now everything works fine,
except...
In GT5 when I have my shifter plugged in my L2 button (Left View Button) go crazy in game only if I hit it. Makes the view switch back and fourth, now if I unplug my external shifter the button works just fine. I have checked my wires and made sure nothing was exposed or touching anything its still happens. So I plugged my wheel into my computer and pulled up Logitech's profiler. And when I press the L2 button it will quickly hit L2, Select, then L2 again. But in game the shifter will downshift but upshift freaks out and up and down shifts like crazy. Any ideas?
i think your problem lies in the fact that you are using the same ground for both up and down shifting.. i think all buttons use there own individual ground. then they are merged later on the pcb. thats the way i did it and it worked with no hitch...
heres my homemade shifter made from pvc. springs and buttons.. i have since upgraded the shifter in to a wooden frame and covered it with black textile.. will post pics of update
