    I'm starting to have my interest on DD Wheel since my Thrustmaster T150 Pro doesn't gave me the feel that i need while playing sim racing game such as AC,ACC, Rfactor2, and AMS2.

    I refer a video made by Peacemeaker Motion and Sim Racing OS thread as my source since it gave me clear reference as what i need atm.

    The main problem now is to reduce the noise from the motor while playing games. Solution that i found was Thanos DD Controller.

    Unfortunately the price of that board is expensive not to mention the shipping cost and longer time to wait for the hardware to ship. I live in Southeast Asia region.

    If anyone got a solution to reduce the noise, it will be highly appreciated.

    the noise is from the aasd driver not the TDD board

    you can not remove the noise

    My mistake. The noise wasn't coming from the Motor but AASD. Didn't the TDD Controller has 12 Bit DAC to help reduce the noise from AASD?

    the dac makes the output to the wheel smoother - it does not reduce noise from the DAC

    The DAC takes the PWM signal from MMOS firmware and converts it to clean analog voltage 0-3.3v ... its not making noise. Rather reducing it compared to what people hearing before, when were using directly the PWM signal and the servo sounded like grinding gear.

    What might be a little annoying noise (saying a little as it literally affecting about 10-15% of the population) is the 10khz whining noise that is due to the PWM switching of the IGBT mosfets of the servo drive. This frequency is fixed and cannot be changed, and is present only when the servo motor coils are "Active" aka "Servo-Enabled".

    No doubt your board is awesome. As for me, the price are my main restriction currently. Everything in USD are 4x the price based on my country currency.

    Appreciate the feedback and assist.

    Only I can solve the noise problem.
