    I think it might be an idea to start with a short shaft on the motor. The movements will be smaller, but ofcourse less stress on them too. Never tried a finished sim, so I am not shure how much movement is needed. i believe its beter with fast movements that react to the game. if the motor struggle with veight, I believe it will not move fast enough either. Its also vise to avoid burning components, instead of having larger movements on the chair.

    I also think it's better to get fast movements. Now I have four holes to choose from in the shafts: 22, 35, 48 and 60mm lenght. Tests will tell which one is the best.

    I didn't get Thanos' H-bridge ( http://www.x-simulator.de/wiki/Dual_Mos ... y_Tronicgr ) to work, and while I'm busy (=lazy), I ordered Pololu VNH2SP30 MD01B motor drivers.

    Hello Whaleman. How did your test with WNH23P30 drivers go? I have been reading at Knobs topic today, and I understand he testet this with amc without luck. I cant find the topic you made about this driver, where is it?

    Myself I think about trying pololu later, but for now I will test the driver Tim is making for k8055 with amc. just have to wait for parts. Maybe it is an alternative for you too, since you have amc? k8055-dual-wiper-motor-control-with-variable-speed-t2795.html

    I didn't get Pololu to work properly with AMC. Link for that topic: pololu-vnh2sp30-motor-driver-t2862.html
    I've read also Knob's topic, he used different Pololu motor driver and if I remember right, there was some sort of wiring problem. Now I'm about to try Kubing's motor controller, he uses it with Pololu without problems. I ordered parts and should be here next week. It's very simple to build and parts costs only 12€ in my local shop! Here's a link to Kubing's controller picmicro-16f887-t2754.html
    I've been following your progression with H-bridge/relays. Sad thing that second Dshmb doesn't work properly yet. Good thing that you continue the project despite the drawback :thbup: . I'm also interested using AMC with relays, as I still need to get 3rd motor functioning.
    It would've been so easy to just use JRK 12V12 from the beginning but as far as I know the time I started it wasn't yet discovered. Now it seems to be lots of different options to choose from when deciding which electronics to use.
