The racing sim scene has always had a strong DIY subculture, as enthusiasts seeking the most realistic-feeling peripherals set out to modify off-the-shelf offerings for greater authenticity. Others go further and craft their own builds from the ground up. [ilge] has done just that, putting together his own set of pedals for sim racing.
The build relies primarily on 3D printed components, with a few springs and some nuts and bolts to hold everything together. Gear teeth on the pedal arms interface with matching gears mounted on potentiometers. These are then wired into an Arduino Pro Micro, which reads the individual pots via analog inputs and then acts as a USB Human Interface Device to the computer.
[ilge] tests the setup with a variety of games, including the popular Euro Truck Simulator and iRacing. It’s a great cheap way to get started with a pedal set for a sim rig. From here, the sky really is the limit; we’d love to see an upgraded version with a load-cell on the brake for better pedal feel. We’d be surprised if an H-shifter isn’t in the works, too. Video after the break.
