    Your bang on the money.

    All the costs are in the hardware. Though if you shop around you can get all the parts for around $1 - $2 each.

    I just wanted to make the brains a bit easier for people since hacking a USB keyboard with the tiny PCB's they have these days is getting almost impossible and is rather complicated if you don't understand electronics.

    So now all you need is this board and just add you own stuff.

    But then other costs are comming.
    For me for example.
    Usb-cable €3
    Pushbuttons 14 x €0,60 = €8,40
    Toggleswitches 6 x €2,60 = €15,60
    Startbutton €8
    Switch with firecap €8
    Box €8
    Bracket €5
    Labels €3

    They ones I used on the prototype are a 2pole 2switch which work fine.

    But I'm trying to find a 2pole unlimited +/- so there is no need to return to the centre but I can't see issues.

    Most issues with the encoders are keyboard delays however I have programmed in some sharp delays plus a button press cache to combat any issues.

    The one for my friend also has a LCD Temp gauge for the PS4 with Peak/Hold.

    Its just a pity the PS4 doesn't have an API unlike the PC version otherwise there would be so much more you could do with it.

    here you can find my Button Box, with rotary encoders (unlimited). and user RMK reported some issue with rotary encoders making strange signals with keyboard controllers.

    have a look at this encoder, unlimited and with additional pushbutton.

    True, but SMS is working on approval by Sony for use of a second screen for telemetry (as far as I know...)
    So, hopefully there will be some possibilities. I would love to see this feature integrated with a buttonbox, fingers crossed.

    On the Project Cars you just assign the buttons by pressing X on your controller then the button and it will register it as a USB keyboard button.

    Great job, this looks really clean. Very impressive for electronic/computer newbie like me.
    How many buttons can be assigned? 8?

    Looks like 13 to me.

    In that diagram only 1 to 8 of 1 to 13 under "Digital (PWM) are attached, but all 13 should be usable if I'm reading it right.

    You can run 20 inputs using the standard plug and play interface.

    Alternatively, I can recode the same board to take multiple inputs per pin but your starting to then get into needing some electronics experience.

    or I could use another board with 54 inputs.
