    Started my motion rig a few days ago. This is the base.

    This is the Universail joint I had to make.

    This is the frame of the seat/wheel/pedals.

    This is how I made the wheel adjustable for me or the kids. I set it at an angle down and back both so it will lower and get closer as a kid will need it.

    Hi @Rocket man congratulation, the beginning is always exciting! Just a few notes to your design:
    IMG_20150405_172130.jpg
    As you can see IMO the wheels will be shaking due to the vertical forces when turning the wheel itself.
    Two the seating surface seems too "steep" from back to front.
    The adjustment mechanism for the wheel is great!

    Thanks Pit for the info!! I'll have to see whats it's like when It's running and make some adjustments. I think I need to drop the seat down in the front for sure about 50mm. I doesn't sit right now. Thanks:).

    Got some painting done today. It's looking pretty good.

    I need to cut some metal in the back as it is a bit too close to the motors. I will add some more metal braces to reduce flex in it.


    IMG_20150419_171656cut.jpg

    Pit suggested that I might need to stablize the wheel from flexing so I'm going to add two bars that are swing down so you can get out better.

    IMHO the moves of the rig are not representing the car moves of the game in real time, too slow and some moves seem to be wrong. There is way more potential to refine your motion profile as @noorbeast has been said.

    Yes seat could be longer. Think I will extend it. I moved the upright bars that connect the motor to the seat, from the second hole to the first so the motors don't work as hard and push faster. It is more responsive now to what is going on in the game. I also moved the control box from under the seat to a spot away from the seat. The seat was lifting up and slamming down on the floor with me in it when I jumped a hill in Dirt 3. It broke a connection on one of my soldered joints in the control box from the impact. It is good now..... It can just thrash around all it wants. I'll post some pics and vids soon just been busy with other stuff. Thanks for the input!!!!

    So here are a few pictures of where the control box sits. I moved it under my tv and had to run all the wires back to the rig.
    Once I had it set up this way and turned it on there was a lot of static in the feedback lines coming from the pots. I run so shielded tv cable( coaxial cable) to each pots center connection then to the ardunio. this still had a lot of static which made the motors just rattle when the rig was just sitting idle. Then I grounded the shield to the negative side of the pots circuit and the signal went really clean. The motors would just sit perfectly quiet.

    I also extended the pedals out farther. I couldn't take the rig out to weld it, so I made a bolt-up extension. This gives me another 5" (125 mm) so my legs are not cramped up any more.

    Then added some support braces to stop the flexing.

    Then some blue led lights.

    IMG_20151001_090457.jpg

    Speakers by the headrest which are the left and right rear on my sony surround sound system.

    IMG_20150930_073214.jpg

    Heatsinks and fans on the motors.(fans are not in the picture yet)

    IMG_20150930_131132.jpg

    And chains and sprockets for the pots which make it work way better than the mini universial joints I had before.
