    Cool, how do you program the AVR, via serial port or a special programmer? Oh, and what environment do you use to code in?

    I guess I should give a go to making my own version.

    I'm using the AVRISP mkII which I believe is a USB serial port implementation. I run (k)ubuntu linux so it's avr-gcc & avrdude from the command line, although I've played with AVRstudio a little bit - it runs nicely under wine, don't know if it'll actually communicate with the AVRISP though.

    Anyway, mk1 is finished! Quick photo here. The little red things on top are miniature push switches. I'm not really satisfied with it, actually. It would be nice if I had a psx controller & mini-A USB socket instead of the pigtails. Also, the potentiometer to adjust sensitivity is inside (screwed-in cover), so if I want to adjust it I have to take it apart. The justification for this is that I didn't want an external knob that might be knocked after finding my perfect calibration, so I'm not really sure what to do about that. And I haven't got the home button or analog buttons working yet. But... it works!

    The details are available from:
    http://ps3negcon.element42.org/ - page still in progress. It's really quite easy to put together, the most trouble I had was getting it all together in the case!

    Looks neat. Glad to help in any way possible, as I know a lot of people would love this.

    sounds great, glad more people are getting into this now. I think you should put a knob on the outside, mainly for sensitivity changes with different ships, or even different games. My negcon worked awesome on ridge racer 7, smoother than wipeout since there are more degrees of movement in that game. how are you handling the sensitivity?

    1) do you have the pot from the negcon plugged into something that can be adjusted?

    2) If so, I would really like to know how to do this, this would save me the time of breaking a yamaha motorcycle wheel every time I make a negcon

    The negcon is completely untouched! It plugs into the device just like it would into a PS1. You just need a playstation extension cable to attach to the circuit.
    The sensitivity adjustment pot basically just multiplies the incoming value from the negcon by whatever factor before passing it to the PS3.

    If you can read circuit diagrams there's one in the zip package on the website. Otherwise I will be putting up a building guide sooner or later which hopefully will be easy to follow! You won't need to break any more wheels

    It would be good to get a comparison between my version and the 'hardware' approach... I wonder if they actually 'feel' the same in the game? It's possible - though unlikely I think - that having to interface the negcon with the microcontroller produces some lag.

    Cool

    Huge kudos to you both, element42 and jabberjaw. It blows my mind that you figured this stuff out!

    Next you need to build a little warehouse in China and start selling...to everybody here, lol.

    about time someone did this
    thanks element42 for the awesome work!, seen microcontrollers doing wonderful stuff over the years(think I saw someone have a ball wired up via microcontroller to a Dualshock2 to play Supermonkeyball ), I just didn't think their was anyone here that had the know how to pull this off

    while a bit hokey looking if you can't find a PS extension cable(hard to get here) you could always use the controller port straight out of a PS1, ever so plentiful

    so your negcon potentiometer, passes to a sensitivity adjustment potentiometer,

    if this is the case, then with mine, I could do the same thing, except from that adjustment pot, it would go straight to the final input on the wheel board, yes?

    where did you get this particular device? picture? link?

    Man, If this works, I will really be pysched, I will basically have a programmable wheel, with sensitivity adjustment. It would also save me 25$ or so cutting my parts price down even more.

    you say there is lag? alot, small amount?

    The device is based around an AVR ATMega8 microcontroller which you should be able to get from most electronics suppliers. The negcon information is passed to the microcontroller, as is the information from the calibration pot, and a suitable output value is calculated by the microcontroller before sending the info to USB.

    Lag: I don't think there's any, but I have spent more time building this thing than testing it. It's plausible because where the PS1 would just read the negcon and use the data, the microcontroller has to read the negcon and then pass the data to the PS3.

    Is it possible to have just the three pot wires go to this microcontroller, then be able to adjust sensitivity with a Knob or such. this would be the final touch on mine. It works great as is, but the adjustment, and less $ making it would be great.
