    Hello
    My name is Antoine, i'm 18, and i'm in engineering school. I want to build my own 2 Dof simulator with recycling material to made my simulator with a low budget.
    I have 12v DC modified wiper motor, an Arduino and a MotoMonster shield. For the moment I used and 650w, 12v 19A pc alim but I will change it for an server alimentation.
    For the moment, I have mounted one motor with a 10KOhms potentiometer to test motors. I used simtools, and motors work but the have no big amplitude. I have think to put some gear on the potentiometer to adjust the amplitude but I have need more information to make my own gear and print them on a 3D printer.
    Furthermore, I want to make a racing seat with a cardan and 2 wiper motor, and I want the steering wheel and the pedals fixed to the frame , but i don't know if I had to put the motor under the seat or on the side. Which is the best configuration ?
    I want help on this project to build a nice project !

    With wiper motors you don't have a lot of torque so your best option is to go for a shoulder mound design, as it maximises leverage: http://www.xsimulator.net/community/faq/shoulder-mount-rod-angles.149/

    You can go for a full frame with fixed pedals but for race sims a seat shaker design, as per the link, takes less to drive it and it provides additional motion cues at the wrists and ankles, but both designs do work, see here for more details: http://www.xsimulator.net/community/faq/full-frame-vs-seat-shaker-designs-which-is-better.213/

    Ok thanks for these advices ! I will look that. With external pedals and steering wheel it is not unpleasant to drive ?

    At the bottom end the G27 represents good value for money, at the top end you can spend a fortune, so you really need to advise what sort of budget you have and member can make recommendations from there.

    I want make a maximum with recycling material. For the moment I have a thrustmaster RGT Force Feedback Pro.

    i think you're asking if having the pedals and wheels detached from the motion feels good to drive and the answer is yes. I have not compared the full movement rig but the seat shaker designs provide excellent motion and immersion

    Ok thanks for these information. I will reflect to this. And it's better to fix TV on the racing seat or not ?

    I did attach my monitor but on my new rig I did not and there is no real difference for me

    Ok, and does the size matter for the cardan ?

    Universal joint ? I'm not sure of the translation ... I'm french and it's sometime difficult to translate :p

    height does not matter but the thing you have to do is to put closer to the seat the lean point

    The balance point ? For my project I will create my seat support, for pedals, seat and steering wheels, find the balance point and fix the Universal joint at this point :)

    not the balance point (center of gravity aka COG).
    what i mean i will try to explain it in the photo. U joint should be closer to the upper frame (green line) and not closer to the lower frame (red line) if you use a long u joint.

    I understand better now ! Thank for these explanations
    When I will have the U joint, I will send you a pics find the best configuration :)

    I have mounted my first motor with a potentiometer to test the arduino code with the motomonster shield.
    But I want try it with Project Cars to see if I had to make modification and see the amplitude of the motor during a race.
    Does someone can make a coins transfer for downloading the plugins ?
    Thanks
