    Hi there :)

    Here is a promissing project for DIY active pedals: https://github.com/tjfenwick/DIY-Sim-Racing-Active-Pedal by Tristian Fenwick
    FYI, "active pedal" by SimuCube intends to reproduce any travel and force profiles:
    mainly you can customize pedal travel distance, brake pressure but also brake air gap, ABS shaking... without any screwdriver or wrench. :)

    "I built this pedal using a load cell, NEMA 23 Integrated Easy Servo Motor, and Arduino Uno, for a fraction of the cost of the official Simucube pedals. While there are still some issues to address, such as shaky ADS1256 readings and a lack of computing power on the Arduino, I'm really pleased with how it's coming along."

    BOM: 250€
    **Some of these parts will be switched out as I only picked them cause I had them laying around
    • 300kg Load Cell $36.69
    • NEMA 23 Integrated Easy Servo Motor 130w ( iSV57T-130 ) $93.93 (Could probably get away with the smaller 90 watt version and cut down on the overall length of the pedal)
    • ADS1256 $17.99
    • 8x 608-2RS Ball Bearing $8.99
    • Tr8x8 Lead Screw with T8 Brass Nut $11.99 (upgrading to a ball screw in the future)
    • 8mm to 8mm Shaft Coupling $9.99
    • Arduino Uno $16.99 (upgrading to a Teensy 4.0 in the future)
    • 2x Micro Limit Switch $5.99
    • DROK 48V Power Supply, AC 110V/220V to DC 0-48V 10A 480W $40.99


    In my opinion, the tricky part is the command loop: highest rates needed, lowest noise, telemetry filtering (just like our direct drive wheels)... I wish him a great achievement.
