    Due to lack of space in a small apartment, and an urge to have an more immersive VR-racing experience i have decided to try to make a G-seat.
    That have a foldable backrest, that is easily moved out of the way.
    It is all thanks to this forum i got the inspiration and, a "i have to try to do this" attitude.:)
    Tho i have very limited programming experience.

    So this weekend i couldn't hold myself and ordered a bunch of stuff off E-bay.

    Arduino Nanos, 5 of them (i have some other ideas as well)

    Servos 28KG/cm, 6 of those. They were relay cheep, so i hope they are up for the job.

    And some Servo extension wires

    All of that will arrive in ruffly a month, so i have plenty of time to design the seat itself.

    I have finally begun the manufacturing of som parts for the chair :)
    Yeah, the arm on the large motor could be a bit longer.. :rolleyes:
    The last pic is the very expensive and over complicated weldingtable iv used for the arm :D

    I am still working on the design in cad, but som parts are starting to come together.
    The concept is somewhat unusual..

    My Motion Simulator:
    2DOF
    Interesting project. Looking forward to seeing how compact it will be. Im quite curious to see how the heave of the whole thing will be. Currently i have all the heave forces in the flaps but ive been wondering about adding a motor to push the whole thing up and down as the flaps mostly just push you out of the seat. Im using an office chair that has so much weight on it now that i have to slightly help it up (when not sitting in it) when i unlock the raise piston so i may add some compression spring to offset the weight.

    What kind of setup are you thinking about?

    Thank you for your interest in my endeavor with this projekt.
    I will try to explain my thoughts.
    I have actually ditched the foldable part of the chair ( i will change the sign) . But it will fit under the desk.
    Here are some pics from early CAD sketching.

    First pick, chair from side under desk.
    Second first, is seat from behind, and last second is the motor with axel, arms, and a spring.

    The heave motor is on the right side of the chair connected to a heave axel.
    The chair has a bearing on each side of the knees, and the heave axels arms are attached under and behind the butt.

    The travel under the but is 50mm upp and down.
    The idea is to have the chair under the desk, and pull it out when needed, and the wheel mounted on a "drawer" to pull out as well.

    I hope i am making my ides a bit clearer, for those who are interested :)
