I have seen the G27 shifter button panel remotely mounted/removed from the shifter for a sleeker install:
Just flush mount it to a dickie box that is just slightly larger, or get someone to 3D Cad a case and 3D print it.
I moved this to a new thread so as not to hi-jack the other button box thread as I need some help. @Clevohead thanks for the idea. I put this together today and for just few dollars and a couple of hours to put together I was pleased with how it came out.. BUT...the red buttons stopped working I thought perhaps the internal plug lead connecting to the PCB had simply fatigued from disassembling the shifter so many times over the passed few days...months.. year BUT weirdly when I push both the far left and far right red buttons together they register faultlessly as the right hand diamond pattern button. The D-pad is also giving incorrect signals and if I hold a D-pad button pressing a red one will change (usually) invert the D-pad signal?! It seems like there is a short on the PCB or something?! Or maybe one of the chips? I have wiggled the plug and wires, and thoroughly cleaned the PCB and micro switches with contact cleaner to no avail. It also happened last night as I gave the shifter one last crack, but came good after another reassemble. Anyone with more experience in electronics got any ideas? OR anyone out there with a retired faulty G25 shifter who can provide a donor PCB and cable? Cheers.
hahaaa success! one of the now redundant PCB plugs for the shifter control had come loose.... I overlooked this before as I was no longer using the plug and didn't think it mattered, but inspecting the board it was evident this left a break in the circuit loop to the red buttons.. so a bit of solder and she's good to go. @Clevohead cheers again for the idea.
Found this while I was bored and skimming through YouTube. Very easy to understand. Warning though, it is very long winded. Be prepared to skip through the video so as not to fall asleep.
