    Finally, the first pictures of my 2DOF, more will come once I cleaned up my mess and the wires.
    I will also add the dimensions then but for now some little tweaks and changes still need to be done.

    Let´s start with the required stuff / shopping list.

    ------------

    SUBSUM: 359,00 EUR
    ------------------

    219,90 EUR - 1x G29 wheel + pedals Ebay: http://www.ebay.de/itm/192079680309
    55,76 EUR - Logitech Driving Force Shifter www.digitalo.de
    ------------

    SUBSUM: 634,66 EUR
    ------------------


    Plus stuff I had lying around. So no direct costs now but of course I bought them once.
    All of this or similar stuff is available for less than 50 EUR.

    - Some wood sheets from old furniture for the "Engine" floor and the pedal base
    - Some bolts M8 + Nuts
    - "Thumbscrews" (the blue cross-shaped) from old Ikea furniture
    - wires
    - insulation tape
    - shrink tube
    - circuit board
    - arduino clone (was about USD 3,50 on aliexpess)
    - steel bar for the motor mount
    - aluminium sheet for the POTS mount
    - aluminium sheet for the wheel mount
    - aluminium profiles 20x20mm for the "dashboard" extension
    - black paint

    TOTAL: 684,66 EUR
    =================

    + Game Engine PC which isn´t really required but I had one POV Nvidia ION left over.


    Tools used:

    - Duro D-ES 153, cheap (~ 50 EUR) electrode welding machine for the steel frame
    - my CNC mill for the POD mount (not really required but I love to use it ;-) )
    - a metal hacksaw
    - a wood hacksaw
    - thread cutter
    - grinding wheel (to clean my horrible weld) called "Fächerscheibe" in german
    - workbench with vice
    - drill with stand
    - wrenches
    - screwdriver
    - swiss army knife
    - couple of pencils
    - paintbrush
    - ruler
    - screw clamps
    - soldering iron

    The usual stuff - you name it...

    Don´t look too close to the welding, I suck at it but hey that is the first time I ever used a welding machine and trust me it is no fun if you have a cheap machine.

    Basically I followed the nice tutorial
    https://www.xsimulator.net/author/RacingMat/
    (Thank you for that!) made by RacingMat and did some tweaks to my setup. I wanted everything to be as variable as possible so I can change it to fit the size of my kids.
    You can move the seat, you can move the pedals and it is possible to change the height of the wheel.
    And you can unmount everything so you can move this to a different place.

    Thanks to RufusDufus for the SMC3
    https://www.xsimulator.net/communit...3dof-motor-driver-and-windows-utilities.4957/


    Things that need to be done / changed:

    - The motors need to be replaced, these wheelchairmotors do work but they are too weak and I assume
    they will die soon. They run on 24/2A so I guess something with 24/5A should do the job way better.

    - I need to extend the wire for the shifter, it isn´t connected yet because the wire is too short.

    - All wires need to be sorted so it doesn´t look that messy.

    Feel free to ask questions or give suggestions :D

    EDIT 20th feb 2017: As promised some more pictures including the dimensions...all other dimensions should be clear by this.

    You do not need to upload any videos with you, just share a video with the rig in action and finally without your head ;)

    Aww he is shy.

    So load up a buddy, girlfriend, wife or a guy off the street... We don't mind, we just want to see your rig.

    Right, a helmet will probably do ;-) ... when I am done with the tweaks.

    OK...what kind of jack do you have used to connect motors to Arduino? They are very pretty :)

    The golden ones ? They are some cinch... oh I forgot these in the list.
    They look nice but they suck here because there is high risk that they connect if you pull them out. The plastic stuff is better.
    I removed some cable protection "spring" part from them which even increased the risk of connecting them and insulated the ones for power.
