    Thanks Hannibal,
    The microphone of the smartphone is very sensitive and in the very small garage the sound is amplified .....
    I hadn't noticed the birds in backgound ...:grin

    Hi guys, I'm back ...
    I burned a power supply and on advice I bought 2 Simukit power supplies, hoping they are more robust.
    I had to modify the case because the new power supplies were longer.

    I also added 2 resistors to be inserted in the second sabertooth even though it is only in the motor, perhaps it was the cause of the breakdown of the power supply.
    I had to make a support to raise the arduino board because there was no more space.

    Then I changed the power of the potentiometers, before 5V were taken from sabertooth, now they are taken by arduino.

    I also changed the position of the motors on sabertooth, now the otors 1 and 2 are on sabertooth 1 and the engine 3 on sabertooth 2.

    First test with simtootls.
    In Arduino I uploaded the sketch that Wanegain kindly gave me.
    Only the motor 2 works following the cursor movement in simtools test, the motor 1 and 3 continue to vibrate and do not follow the cursor movement.
    Can you help me .... Thanks

    I mounted the upper base for the second test.
    Everything seems OK.

    Now I have to change the parameters to find an exact 120 ° working angle.

    I have already downloaded the iRacing plug-in.


    Do any of you already have a good set of simtools for iRacing?

    Thank you

    Hi guys,
    here is my finished project.:thumbs



    After 5 months of research, readings, questions ..... finally my 3 DOF is working ....

    There are still small adjustments to be made with sintools tuning center, but this is already giving me a lot of satisfaction.

    I noticed that the structure with the applied forces moves a little, I already know where to put reinforcements to stiffen.

    Also because everything is mounted on wheels.

    I can finally go on a more relaxed vacation ...... hahaha:grin:grin:grin

    Hello guys,
    I made some changes to make the structure more rigid.
    As you can see in the previous video the structure moved too much.
    I added three bars as shown in the photo, now it's perfect, rigid but not completely blocked so the mechanical parts are less stressed.
    I put the seat belts, I feel the movements better ....
    I added 3 fans placed in the pedal board that give a non-annoying flow that reaches the face, excellent with oculus on hot days.
    Goodbye see you soon

    Wow really nice work Fabio!
    2 question and 1 suggestion...
    -how long are the levers?
    -what P value did you set in the sketch?
    -try to fix the belt attachments in a fixed point of the structure. in this way, when braking you will feel it tighten (see my project)

    Hi Gigi,
    the levers are 10 cm
    The P is the Wanegain standard ... 100
    The belts are anchored to a fixed point, but with an elastic band.
    Hello
