Michael Rechtin is building a DIY Motion Simulator that he hopes will transform computer simulation into a theme-park-like thrill ride with the addition of realistic motion.

Flight simulator enthusiasts will go to great lengths to create the most authentic flying experience, with multiple large monitors surrounding cockpit-like rigs, attached to realistic yokes and pedals.

As impressive as the simulator is, the electronics are quite simple. A Raspberry Pi 4B is connected to USB pilot controls, and in turn uses a Teensy 4.0 to control powerful stepper motors that move the seat. In addition to flight simulator software, the rig can be used with an RC airplane or drone by mounting an MPU6050 IMU on the aircraft, which transmits pitch, roll, and yaw data so that the seat’s orientation can match it.

BOM, code, and extensive documentation can be found on GitHub, and you can see it in action in the video below.
