Mini Force Feedback Momo Steering wheel

This is the design and STL files for the miniature Force Feedback Steering Wheel I made with spare parts leftover from other projects. The best feature it has is its rotation range of 720 degrees, like real steering wheels and has no real hard stops, apart from software defined ones.

The motor is powered by a 3.7v 2500mA battery that is charged by a battery charger (Adafruit) and then step-up to 18.5v. The small gearmotor that was used can operate on 24v so with less voltage stalls easier without shorting too much current. The motor is driven by a tiny 1A hbridge.


The FFB controller was designed by me back in 2015 and has DB9 plugs on the back so you can attach the original G27 Shifter and G27 pedals that I have. It runs MMOS Firmware and has additional wireless button support.
I'm placing here a link to the copy of MMOS firmware I use:

For testing the device I used 4 buttons attached on a adafruit p
