    hey Guys,I'
    I'm new and have a question. First of all I've never messed with this stuff before so have mercy. i have a MOMO racing wheel and spliced the wires from PCB to the force feedback motor and looked at the voltage drops and rises i want to hack this signal, boost the voltage and send it to a wiper or some sort of motor to move a chair what do I need to buy? i know how to construct this but not how to get the signal to a motor. its for nascar racing 2003 living in north carolina im a huge nascar fan :sos: .

    Hi Jesse and welcome!
    Some time ago I had the same thoughts and came across this forum :)
    If you insist to use the signal from the MOMO I would connect the wipers via a Sabertooth dual 25A motor driver.

    Now there’s even a better way than hacking the signal of the MOMO: Use the x-sim software.
    This software extracts more accurate and more meaningful data out of the game directly.
    The simplest way is connecting one or two (or more ;) ) jrks to the wiper motor(s), a power supply, a potentiometer(s) for position control and the x-sim software. Done.
    There is plenty of information in the forum how to do this. For example here.

    Enjoy your stay here!

    thanks you very much! im going try to stay with the feedback hack just because i've thought about it for forever.
    is there a cheaper version of this 25 a motor driver that might be as good?

    The SyRen 10 from the same source provides up to 18V 10A continuous and 15A peak and is 60% cheaper.

    do i assume you want this chair to just jerk you back and forth, its not goint to let you feel turns. imagine what the wheel is doing, its much more complicated then just riggin a motor. you really should look at x-sim.

    agreed with shannon and value.
    If you want the chair to simply move as you turn the wheel and no real motion , hook them up via the hack in the wheel.
    If you want proper motion, 2 x JRKS of which run 14v at 30 amps continuous .
