    OK, time for my own little thread.

    As i mentioned, @Bastiuscha helps me a lot with my build so everything went really smooth. At least until now! :D

    My Parts:
    Arduino Uno ( changed the clone with a original R3)

    12v 100a server power supply (HP DPS-1200FB)

    Link: HP DPS

    2 DC brushed motors (12v 370w 50:1)

    Link: 90ZYT

    2 contactless potentionmeters (RTP180LVEAA)

    Link:RTP180LVEAA

    for the potentiometers I needed two connectors

    Link: 282087-1

    and pins

    Link: 282110-1

    Sabertooth Dual 60A:

    Link: Sabertooth

    Everything connectet together:

    bass shaker

    Link: Sinuslive

    audio amplifier

    Link: no name



    as a seat i got a Gtultimate V2 + Flight Pack

    Link: GTultimate V2



    as a joint for the seat I used an old nissan 200SX S13 propeller shaft (Kardanwelle)

    For some first testing i bolted everything on a wooden plate.
    [​IMG]


    first the seat to find balance
    [​IMG]




    after that I added the bass shaker and the ball joints
    [​IMG]


    I mounted the motors a little bit higher so the lever can spin freely. I tried to get the magnets on the shaft by using wood but that din´t work out well an will lead to my profile avatar later on.
    [​IMG]



    Everything ready for smc utils! :D
    [​IMG]


    After everything worked well in smc, i booted up Sim Tools 2.4.1 for the first time and set up the software with help from bastiuscha.

    Of course I clicked on output testing without thinking. Motor one immediately lost his shit and started moving at high speed. The movement was so hard that the magnet fell off and I had to cut power to stop the motor.
    [​IMG]


    I rolled back to simtools 2.4.0 and found a better solution for my magnets.
    [​IMG]
    [​IMG]


    Everything works now, time for life for speed!

    I crasht in a wall and this time, motor two started spinning.
    With my weight on the seat, the motors wiggled so much, that the sensor lost the magnet for a short moment which leaded to the motor spinning around.

    it got pretty late yesterday and I still have to connect everything for the next test.


    also looked for a kill switch and i will go with a car battery switch like this.
    But for time being my dad will akt as a kill switch.:D

    Had some issues with the motors. They stand still after hart movements. Changing the psu and the power cap did not help. Turns out the cables were the problem. Changed the old ones with copper cable and everything works perfect now.




    Total time in use : 71h :)
