Hi guys..

So, I have this crazy idea of doing a custom sim racing set: steering wheel, pedals (w/ clutch) and gearbox.. I have the mechanics and electronics handled. I want to know if there is a away of making this compatible with GT5/6 like a normal set like G27.

Basically, I want to know if there is a sort of development help from Gran Turismo to things like this.

P.S. I'm from Portugal and my english is a lit bit rusty.

Cheers
 
Nope, not for the PS3. All hardware needs to have the proper license to work on a PS3 and an Xbox for that matter. However, you can do this for the PC. A little more research in that direction will reap you info on this forum as to what you will need to make that happen.
 
Pretty much what basher said, and I believe that he is one of those that you should research. Well, his products anyway. However, if you are going to scrap a wheel to make a wheel, well, why not just use the wheel?
There is some good reading about that sorta stuff here.
 
I can't believe that is not possible. The G27 or 25 or whatever board can't have ALIEN information, you know what I mean ? I think it can be done by using the same usb descriptor that others set have. I mean, PS3 won't recognize as the other set ?

Of course you can do that. That's exactly what Fanatec does. However, you might save yourself some trouble by using the board from a G27 as a building block for your wheel. It doesn't need to drive the motors directly, it just does the processing. Connect your own motor drivers to it. Or, start from scratch, your choice.

Polyphony Digital is not going to help you though, if that is what you are asking.

If you know C, this has some good info in it, ignore everything not G25 or G27:

Also good to look through probably:

https://www.lfsforum.net/showthread.php?t=74115&page=2 (the descriptor is buried in there I believe)

The information is out there, somewhere. Or you can obtain it yourself directly from the wheel, if you have one.

My problem is that I don't own a wheel. I search a little by parts of G27 or G25 but nothing.

That stuff is a good start, thanks. Please, if anyone has more info about this, link here.

You can often find Logitech Driving Force Pro wheels pretty cheap and as you're not keeping the mechanism, just the PCB and whatnot they probably aren't THAT different than a G series for your needs and a heck of a lot cheaper.

Also try the buy/sell boards and ebay, you see parts wheels show up there often enough.
 
That is true. Since the shifters and pedals have a standalone adapter available now they can be a little harder to find for parts tho.
 
The real big problem is the force feedback, is not so hard build a great wheel even for ps3, you can use any board of any ps3 control out there, but the big problem is the force feedback, consoles have close hardware, you have to pay if you want their protocoles, and also you have to pay to poliphony digital if you want to use any wheel in their games, thats are the real problems with consoles.

The best thing you can do is modify a old wheel and improve the feeling and the force foeedback

The thing is I even don't want to use the force feedback at least for now.. My problems start with controls that aren't used by a normal controller like the clutch or the manual gear..
 
I was doing something similar to what you think, but he complexity of building it took me to go to pc.

If the gearbox is sequential there is not many problems, but if in H there things get complicated, it takes a little ingenuity and knowledge in electronics.

The clutch is not as complicated , also electronic knowledge isneeded, I wanted to make a brake pedal like brake pedal and asociate it to the clutch button in the control, as the pedal is pressed generated a PWM in relation to the clutch,
if you pull the clutch in depth will have a 100% pwm
if you pull the clutch in half will have a 50% pwm
and so for all positions, but perhaps for purists do not like them

Yes, what you are trying to say is have a analog signal coming from the clutch like the real one instead of having a digital signal that only have two states (pressed and unpressed) ?

From my readings I learn that sets like G25 combine clutch and brake pedals signal in a analog signal that the PS3/Game interprets them, I think..

I'm far from understanding all of the parts that are involved on this but it is a good hobby ;)
