    Hi,

    Well it looks like I have a new project in the wings.

    The goal:
    Build a motion platform for the car racing games on the PC, with the Seat, pedals and wheel on the platform.

    The parameters:
    - Cost <$2.5K (excluding wheel, pedals and tools).
    - Must fit in a smallish room
    - must use existing PC for the main machine, but can extend to old laptop for motion control etc.

    The parts list:
    - 2 Linear actuators.
    - Some Square hollow steel for the frame
    - Some ball joints
    - 1 low slop Universal joint - for the main frame pivot
    - some bocca rod for bracing etc.
    - 1 Racing seat (To be sourced).
    - additional nuts, bots, zip-ties, and foam as required
    - some rubber mounts to stop the final assembly jumping around the floor

    The Tools list:
    - Screw drivers
    - Hack saw
    - Files
    - Cutoff saw (more power...)
    - Mig welder (to be sourced)

    So until the first lot of parts arrive, there aren't any photos... but if you have q's fire them off or just let me know you are interested in the build....

    Cheers,
    AP

    Wow. This is going to be epic. Got any drawings on your designs or anything like that?

    making the thing is easy. getting it to interface with a game is hard.

    Possibly.... I think it will be a little easier for R-factor, LFS, Simbin Games, and possibly... Dirt2.

    I'd love to help with some plugins for rFactor. I have experience helping Leo Bodnar with his SLI-M projects. http://www.leobodnar.com/

    There are already plugins for the major sims like rFactor to use with X-sim..

    All the hard work has actually been done for the end user and reports state that the end results are better than the Frex system.

    You're probably better off having two actuators at either side underneath the back end and a large ball joint mounted underneath closer to the front, with the actuators mounted on an outward slant so as to keep the CG low(stability). Something like this...

    You have to make sure all structures are made of a collection of triangles (i.e. no quadrilaterals) to ensure proper rigidity.

    As the actuators are somewhat limited in force capacity, I will be getting the structure as close to balanced as possible, that way the linear actuators only need to move the structure, not hold it up.

    On the strength side, agreed with the triangles, just gotta put them in the right places and away we go. The trade off with more material is more weight, which will be a performance killer.

    The electronics side has left for Aus at 3:22 am on March 01, 2010, so around 6-10 days and that side will be here.

    Triangles will decrease the weight of the frames, as stresses on the beams will be that of a push/pull nature rather than a bending one. I'm no engineer, so this is probably the limit of what I can give you.

    Apologies if the response offended, it wasn't meant to.

    FWIW your sketch is significantly more sound than mine!

    Agreed that the triangles are really strong, and that the beams are only strong in tension/compression. I just need to use any material sparingly, ie where the extra torsional rigidity is required is where the triangles will be! :)

    Also does anyone know of a good trade tools place around Hornsby. I think a 120 amp Mig and a cutoff saw are needed...
