    Default PS3 NeGcon - Can it be done???

    See my photo album for the carnage - warning - explicit content!

    http://www.wipeoutzone.com/forum/album.php?albumid=33

    If I can make this thing work....

    Edit: A bit more info to chew on - any input or ideas? Feel free to contribute!

    Thought process currently - take the guts from a PS3 controller - and wire buttons to those inside the NeGcon. As for the NeGcon X, [] and L1 will have to be modified, as they're analogue - thinking of pulling the carbon pad out of the potentiometers and masking them so they respond as switches. (this, should be easier than rigging up a new switch to go into the existing locations) The Twist-Action of the NeGcon will remain intact, but the range of movement will be a lot tighter - 1/2 to 1/3 of original range for max-to-max - hoping to have the potentiometer replaced with one from a PS3 stick (swapping carbon pads between the bodies). As for the PS3 controller - stuffing the mainboard inside the NeGcon (this WILL BE one of my biggest challenges of this project, no doubt about it), installing 4 extra buttons (going to use mini switches for L2, R2, PS Button and Select).

    Phew - my brain are dead for naow!

    I am curious to see how or if you will manage to split the controller PCB in two halves... I can't for the life of me think of a way.

    Good luck on your project.

    I think you might have an easier time if you used one of these Saitek PS2700 controllers as a donor.

    http://www.saitek.com/uk/prod/ps2700.htm

    The D-Pad and Analog stick section is interchangeable, "Cyborg" they call it,you just swivel the pads 180 degrees.

    It's would seem that part of the problem you face with separating the circuit board might have been solved for you?

    [No, Saitek are not going to do a NeGcon type controller,I've already asked in case you were wondering ]

    Couldn't you remap the controls in game so that you didn't have to swap the analogue controls on the NeGcon,the R2 L2 triggers on the sixaxais are analogue,and they work perfectly well having a digital function mapped to them.

    hey, 1/3 of the range would be good, if you cannot set the twist. Who the heck uses the negcon at 180 degrees anyway.

    you might have to use a regular sixaxis instead of a dualshock 3, the DS3 has a higher-precision potentiometer for each axis on the control sticks, so I dont know if you would be able to rewire it properly.

    I could probably7 pull it off, along wiht a bunch of other obscure things Al has suggested to me other times, but I just never have the time available.

    I used to hit 90 degrees pretty often. Too much?

    I would say yes lance. Arnaud sets his at zero, BUT it is not really zero, I think the minimum is 30 or so on the actual controller, because there is still play in the controller. It's better to go left right really quick, but still be accurate. This is for xl of course. For wipeout1, jeez, I think I set mine between 50-80 depending on the ship I use, and in wo3 I set it between I think 51 -67, once again depending on the ship. What are your settings for those games?

    NEED HELP HERE I am almost done, but hit a snag with my added dpad, and face button pad

    Both pads, have 5 wires, one wire for each button, and one for ground.

    On the base pad they are being plugged into they have slots for all wires on one piece. which is not a problem, BUT the buttons are being recognized as always on. Do all the wires need to be plugged in for this not to occur? The other sets of buttons I put in worked fine, even on the boards that had l1 and r1 on it, and the one with l2,r2, that worked fine as well. I was able to test each button individually.

    Anyone?

    Without seeing what you've done it's hard to tell what's wrong, not to mention how ya have it all wired up, and as you've used that steering wheel without knowing how it's setup even if I did see it I couldn't swear as to what may need to be changed around to straighten it out.

    If you'd have used a PS3 controller I could give ya a load of things to try out, but with that wheel as your controller board yer kinda on yer own as I don't even know what it is, let alone had it all apart and traced out to see how it works.

    I am not an electronics genius here. there is no way that I could use a regular ps3 board without knowing exactly where to solder, ect. This board is simple. It turns out that for some buttons/dpad boards, it simply sets itself to on, and you cannot get around it. I tried out a variety of buttons and some worked fine, so it's just going to take me longer than I wanted, thats all. I am going to need to take out the dpads that are in the negcon at the current time unfortunately, but before I do, I'm going to set it so I can play a tt at least (without brs)

    Al, did i ever told you you are a pure tech-genius?
    Can't wait for the final result ( will open cam this week to let me see your new Neggie Wonder

    Who said ya were? or that I was? The only kind of button that 'sets itself to on' and stays that way is a latching type of switch, and they don't use those for buttons in controllers. Also ya couldn't use that wheel there unless ya knew exactly where to solder, etc., and since it's not working correctly it seems that board's not so simple after all.

    If ya want a decent enough thread to take some of the confusion out of the PS3 controllers have a look here..

    Maybe Ih8you or RDC can help me here

    engadget.com/2006/10/10/how-to-analog-control-stick-for-your-sony-psp



    this site shows the pin layout of the psp vs a regular analog stick, and how to connect an analog stick to the psp. Since the negcon has only three pins for the turn, where would these three wires be connected to from the negcon potentiometer?


    On a side note, I have now finished two negcons. Second one is better because the dpad assembly is a little better, and the right side in intact completely with no different buttons. It is also better because the wires are smaller.

    It's the same as a Stick, the neGcon just has the X-Axis (left/right) where the Stick has and X-Axis (left/right) and Y-Axis (up/down), so you'd just connect it to the spots the X-axis of the Stick are using, which going by that diagram is A/B/C, with B being the Wiper (center pin) then A and C being power/ground, and if ya get the power/ground backwards it'll just work backwards is all and swapping them will fix it.

    xbox negcon now is a reality. I wish I had the thrustmaster wheel for it, but I ended up just using the yamaha motorcycle wheel that was made for it (kinda). The yamaha wheel comes with a controller converter for xbox/gamecube, and has sensitivity settings, although with this game, I would rather have it perform like it does on the other wheel, set at 45 degrees. Anyway, I think this will work well when I get used to it.

    IH8you, I was wondering how the one you were making was working out?

    Default Oh yeah!

    I've just succeeded in building a microcontroller-based circuit that allows me to use an unmodified negcon on the ps3. I'm pretty pleased as I've spent practically every spare moment for the last three weeks trying to figure this out!

    At the moment it only works on full sensitivity. This should be trivial to code a solution for, but I'd like to use a potentiometer to calibrate sensitivity so as I have to learn ADC routines for the controller it might take a little while to get right! Also, only the twist is analog. I think I should be able to get the other buttons analog but it's not a priority as I've never used them that way. Likewise the lack of home button.

    quick picture: (my camera is ) http://www.wipeoutzone.com/forum/alb...pictureid=2081

    more details to follow!
