    ...simple triple monitor base for desk use.

    ...the wooden "base" can slide forward on the desk to embrace the driver when driving or backward to leave space for the keyboard and mouse(for games that require mouse and keyboard that is :p ).

    My first attempt to fit the dash was this:

    dash template 1a.jpg

    But after some thought, i didnt want any cablework floating around the steering axle so i went for a more simple approach.

    dash1a.jpg
    First fit was ok.

    "ingredients":
    a)A plastic project box of the proper size to fit the tm1638 board (and have some extra space to fit a few toggle switches at the sides to take advantage of the 8 buttons of the board)
    b)A piece of plexiglass
    c)Some rough cutting drilling and sanding

    The project needs some polishing of course and a final touch with 3d carbon-fibre sticker for some more pro look.

    Total cost: less than 20 euros.
    Fun factor: "priceless".

    I found this interesting page with info on how to:

    Emulate Thrustmaster T500 GT Wheel electronics with Arduino


    ...fact is that i ve been looking for something like this for a while now.

    Since the t500rs wheel has more than enough buttons...it makes it a lot easier to mod the base with an aftermarket (300mm-330mm) racing wheel and put some (up ot 13 in fact) buttons on it...or even equip the wheel with rotating shifter paddles that send their signal through the arduino board directly to the base electronics.

    hyd upgrade.jpg

    cost: 34 eur
    cylinder(+reservoir): 12eur
    sensor: 16 eur
    adapter: 6 eur

    i am planing to fit the sensor directly on the pressure output (leaving a small pocket of trapped air) and see how it feels.

    i also designed a mini-chasis that i will use as a platform to fit the cylinder assembly on the pedals without damaging them.

    multi-purpose t500rs pedals mini-chasis.jpg
    paper preview:
    paper mini chasis.jpg

    and how it will fit the pedals

    paper mini chasis 2.jpg


    its a multi purpose chassis that can be used for every pedal (eg for a realistic clutch pedal modification) and can be securely bolted to the oem screw holes.

    hyd pump.jpg

    the tilt will ensure that a small amount of trapped air (which will be used as travel regulator) will remain permanently inside the cylinder.

    I finaly had the time to finish my wheel button plate.

    Was an easy job.

    Some rough drawing...
    1st pass.jpg

    Some paperwork for fitting tests...

    2nd pass.jpg

    A trip to the local workshop...
    3rd pass.jpg

    Some drilling/sanding/brushing ... and voilà...
    preview.jpg

    when i get more time i ll paint the surface some matte black color...and start with the circuitry.

    Fitted...
    mounted.jpg
    vs stock...

    The wheel is a 31cm (stock is 29cm) chinese knockoff from ebay (30 usd).
    Hand stitched fake leather...but...
    Very good value for money for a race sim.

    nice wheel mod @pipis2015 . what's the diameter of the wheel?

    The plate is 1,5mm thick.
    I think 1,0 mm would also be ok.

    i know its not that bigger than the stock one but does it have any difference in FFB perhaps some more clipping?

    My early experience is this:

    1) The extra size-diameter (although only +2cm) makes for a nice difference in feel (Maybe a placebo?).

    2) The fake leather (which is also padded) feels better (and softer) than the oem rubber/plastic coating (I don’t use gloves so far).

    3) I didn’t feel any noticeable change in FFB.

    EDIT:
    4)The wheel feels like more in proportion to the graphics(while this is true it is also hard to explain considering there are ways to tune the graphics no matter what ones wheel size is).

    My 2cents regarding T500rs FFB and clipping (I hope I wont start a war).

    As long as you have correct in game settings (which is what most people tend to mess up) and keep the master FFB in the T500rs driver panel between 50%-70% then you don’t have almost no clipping at all.

    Check the chart.

    http://isiforums.net/f/showthread.p...que-Capability?p=327348&viewfull=1#post327348

    50% is more linear at top end (80%-100% game transmitted torque) and 70% is more linear on the low end (0%-20% game transmitted torque).

    So what is the notorious "so called" T500rs clipping issue.

    Well the T500 rs is a 6nm wheel. (most everyday cars dont even reach that number on their steering wheels).

    So every user attempting to make the wheel feel stronger than this is doomed to induce clipping on the top end.

    Actually if someone wants to feel on the T500rs the torque of a 1980 F1 car (a lot more than 6nm obviously)that means that he has bought the wrong wheel. For comparison purposes the g27 is a 3nm(if i recall) wheel and the Direct drive wheels can go beyond 30nm.

    The following link provides some good info on the issue.

    On page 3 you can read what was “the peak torque a driver could transmit with his hands to the steering column while seated in the car”.

    the following video is for those who want to study “a little” more.

    good project!
    what's new? How is the feeling?

    About the prices, could you share the URL where you found such cheap parts...:)
