    Hey Everyone,

    This is my introduction into the sim racing world. I've been watching a lot of posts trying to figure out which route to take for my first build. I have decided on a 2DOF Seat Mover style based on Halloween2Go's design.

    I have already built a MAME arcade and have wanted a driving cabinet added to the mix for a while. My youngest daughter gets the most enjoyment out of the setup we have now. She loves to play City Card Driving in VR. My favorite is Assetto Corsa with a little Dirt Rally VR on the side.

    Any advice you can provide so I avoid any potential problems is very welcome. I guess I'll start with a list of items I have ready to go in my cart, and we can see if it will be what I need.

    Motor x 2: LINK

    Potentiometer x 2: LINK

    Arduino Uno Rev3: LINK

    Motor Controller x 2: LINK



    Here are some pictures of the evolution of our setup. It has been a blast up to this point and I'm excited to get a little motion going.

    Great start :thumbs

    Just some additions to consider:

    You will need a universal joint, cutting down an old tailshaft is a cheap way to go, but you can buy flanges.

    With PSUs you can check out those made for LEDs, which come in a range of capacities and tend to be pretty tolerant of power spikes on fast reversals, or you can modify sever PSUs: https://www.xsimulator.net/communit...ver-power-supplies-as-cheap-powerful-psus.54/

    With Hall Sensors the easiest way to mount them is direct with a suitably sized flexible coupling, but there are other possibilities: https://www.xsimulator.net/community/faq/how-to-connect-protect-a-potentiometer.13/

    Great, thanks for the reply.

    I did source a beefy driveshaft from the junkyard when I picked up the seat to replace my temporary office chair setup. So I now have 2 u-joints ready for action.

    I’ll have to look into the power supply situation, it looks like the video I was watching from DMax used an old car battery as the source. I’ll read up on the links you attached.

    As far as the motors and other components from above, are these acceptable? If so I can get them ordered up.

    Ok. Now that I have narrowed down the design possibilities I’ll look into the calculations.

    I’m figuring on building a compact seat mover 2DOF for now. I don’t have a large budget so I’ll be getting parts as I can afford them so I’d rather stick to well known designs as much as possible, to avoid purchasing materials that aren’t up to the task.

    The more compact the design the greater the need for the likes of the 50:1s, as the greater the torque needed given the limited inherent design leverage.

    Personally I use 200W 60:1 motors on my compact rig.

    I really appreciate the feedback. I’m looking at SimCalc now as well as the 2 motor links you posted. I don’t see any torque specs listed on either one, at least in lbs/ft.

    Details are in the Description sections, here you go:

    25:1 LOAD BETWEEN 30-40 N.M. (22-29 FOOT POUNDS)

    50:1 LOAD BETWEEN 50-60 N.M
