OpenSimPedals - DIY 3D Printed Sim Racing Pedals With Loadcells

Introduction: OpenSimPedals - DIY 3D Printed Sim Racing Pedals With Loadcells

OpenSimPedals are built for DIY sim racing.

Goals are :

  • 100% 3d printed
  • 3 pedals optional : clutch, brake, throotle
  • LoadCell pressure sensor
  • Arduino
  • Oled & buttons for autonomous configuration : deadzone/range by pedal
  • Heavy forces : 70kg for the brake
  • PCB or breadboard build
  • Shared : STL + source code + PCB
  • Vibration motor holder
  • USB and PC joystick emulation

SourceCode & Electronic : https://github.com/manoukianv/OpenSimPedals

Supplies

Coming soon

Step 1: LoadCell and Push Part

Use 2 screws, and add bearings.

Step 2: Arm Assembly

Screw the footprint.

Screw the vibrator motor holder.

Add bearings.

Use M8 screw / bolt to fix ball join (or alternative).

Step 3: Prepare Bases

Insert holder.

Insert bolt.

Step 4: Fix the Arm on Bases.

Follow the picture order.

Step 5: Prepare the Spring Shaft

Follow the item order.

Step 6: Assembly Spring Axe and Loadcell

First fix the axe on the arm.

Screw the loadcell.

Step 7: Fix the Loadcell Holder

Follow the order on the picture.

Push item is in the rear direction.

Step 8: Screw the Pedal Tilt Setter.

Screw like on the bottom left.

    Question 1 day ago on Step 7

    Is this still a WIP? When can we see the BOM?

    What's the model/part number of the load cell you used? Could you provide a link to where I can purchase one?

    Awesome, I'm very excited to build this. Waiting for the BOM files uploaded.
    Thanks.

    Hello
    I start to collect the material to build that :)
    Could you tell me the characteristic of the springs, like dimension, strongness
    Thx :)

    Hello, i have take simple spring from my toolsbox. What i can say :
    */ for the brake is use a load cell, i use a 5kg loadcell
    */ for the throttle it's a 8mm inner spring, 100mm length and aroung 5kg
    */ for the throttle i make an important upgrade ; loadcell works bad, i use a hall angular sensor a AS5600.

    Thx for answer :) I agree completely that load cell is not good for throttle, even I think for clutch you can use a normal potentiometer, the real clutch mechanical work by distance don't by force, load cell is correct only to break. You will update the code for new throttle sensor? Regars :)

    Would you please tell us the spec of the LoadCell that you used? Looks very nice, good work!

    Hello, I want to add just a Clutch Pedal to my 2 Pedal Setup, can I use your project to do this?
    And the second question, can you provide links to the Hardware BOM that you used, for example type of LoadCell, Springs and so on?
    Is it possible to flash your Software also from Arduino IDE, or it needs a conversion to a sketch Format?
    I would like for the beginning to make a Pedal without the OLED and buttons functionality.

    Hello,
    I push some technical data on the github project.
    For the clutch, it's for the moment the only pedal i don't print to test. But Yes this project use an standard arduino (uploaded from arduino IDE) and can be set for only 1 clutch.
    It's works whitout the oled, but is more easy so setup with the oled (range/deadzone)

    Ok I will check it up.
    I already made one pedal which is working with Arduino, but it is too tall.
    Is your Clutch Pedal also using a load cell, or is it potentiometer based?
