I've been looking thru Todd's CST pedals and bought his DIY plans :drool::drool:. I play more on consoles (FM4 and GT5) and it's too bad that these awesome pedals only work on PCs.

My question, to master modders, is it possible to use the circuitry in my std pedals and make it work on CST pedals? I understand that the Std pedals don't have any load cell circuit but is it possible to use the pc board in Todd's design and some how hook it up with my CSR wheel?

Todd mentioned that he has something in the works that can make his pedals work on PS3 but if I could connect the pedals to the wheel then i could use them on FM4 too 👍
 
You could use the potentiometers from the fanatec pedals? But to be honest I have no idea what I'm talking about but I think this is an interesting idea so don't want the thread to die :)
 
I meant to reply to this yesterday... Oops.

Now, I don't know anything about Fanatec hardware nor anything about the CST pedals, but I do know that people use G27 load cell mods with GT5 which must mean the load cells can be interfaced directly with the G27 wheel, meaning (of course) that the load cell output either is or can be converted into a potentiometer signal, which is a voltage varying from 0 to 5V. Quite how you do that is beyond me as I've never even seen a load cell before, but it should be perfectly possible. I assume the clutch and accelerator pedals are potentiometers which would be very straightforward, though.

My recommendation would be to look into load cell mods for various wheels and see if you can get a circuit that converts the load cell signal into something that will work with a Logitech, Fanatec or Thrustmaster wheel as all of these use potentiometer pedals. I know Leo Bodnar sells a board to allow you to use a load cell with a PC as well, but that's not what you're after of course.

I'm sure you'll find something (or someone) useful, but I'm going to say yes, you can definitely make this work. How handy are you with electronics?
 
There's no actual "circuitry" in the Fanatec standard pedals. Just pots. The signals on the Fanatec wheels go from 5v at rest down to about 2.3v when fully depressed.

Also, the wheels only read 8 bit (256 steps) unless you are using clubsports or similar which communicate with the wheels through digital communication in order to achieve 10 bit resolution.

The short answer is, there's no reason you can't do what you want. However, connected to the wheel you will only get 8 bit resolutions and the pedals work "backwards" ie. pushing down on the pedal makes the voltage go down.
 
@neema_t
good point, I will try to look into g27 mods and see if this is something i could do..

@Mrbasher
:ouch: 8 bit does not sound so good. Thanks for this info. it would seem to be such a waste to have this good a pedal only to use 8bit.

I guess my follow up on all this would be if there is a way to wire 2 pots and a load cell to output to PS2 as this is the interface in the wheelbase for the pedals. I will research this but if anyone has a quick answer; please let me know, much appreciated!

Thanks everyone!

Well... IF you used all 8 bits, it wouldn't be too bad and you honestly might not even notice. ;) Now, I don't know for a FACT that it's only 8 bits, not without connecting the wheel to the PC to look. I'm just going off what Fanatec says on the subject. Let me know if you want help making sure you use all 8 bits... It's best discussed in a PM probably.

As for connecting stuff... For the load cell you need a load cell amp like the Derek Speare's or Bodnar amps, or you could make one, but I wouldn't recommend it. And a load cell of course. The rest is just connecting wires. Let me know if you want the pinout for the connector. :)
