OpenRidingController – DIY horse riding controller for the PC

Gamers are losing it over a homemade horse controller that’s weird, brilliant, and hilariously niche

TLDR: A DIY creator built a horse-riding game controller for PC and Mac, complete with rein-style controls for horseback games. Commenters were equal parts impressed and unhinged, praising the creativity while joking that it looked suspiciously not safe for work and begging for wild motion-seat upgrades.

A maker has unveiled OpenRidingController, a homemade PC and Mac controller designed to mimic the basics of horse riding for games. In plain English: instead of just pressing buttons, you use a custom-built setup with printed parts, sensors, and a little rein-like handle to make your in-game horse move. It’s still a rough-around-the-edges project — the page literally says “TODO: Add pictures” and “Add guide how to use” — but that only made the crowd even more fascinated. After one commenter dropped a video demo, the reactions went from cautious curiosity to full-on delighted chaos.

The biggest mood in the comments was “this is absurdly niche… and I kind of love it.” One person admitted they feared it would involve a full saddle on a fake horse, or worse, be controlled by stirrups, before being won over by the tiny bridle pull. Another openly celebrated it as a wildly creative answer to a question nobody asked. And then, because this is the internet, the thread immediately swerved into jokes: one commenter confessed they were “moderately surprised” the project was safe for work, which tells you exactly where some people’s minds went the second they read “horse riding controller.”

The funniest escalation came from users dreaming up chaotic upgrade ideas, including a motorized seat with force feedback powerful enough to throw you across the room when you “fall off.” So yes, the project is real, but the comment section turned it into something even better: part admiration, part roast, part theme park pitch.

Key Points

  • OpenRidingController is a DIY game controller for PC and Mac that aims to emulate basic horse-riding behaviors in video games.
  • The hardware is based on an RP2040 Zero, four TCRT5000 infrared reflective sensors, and a frame made from 3D-printed parts, steel pipes, and M3 hardware.
  • The project currently uses CircuitPython 10 for rapid prototyping, with Arduino C mentioned as a possible future option.
  • Required software components include several libraries such as Adafruit CircuitPython HID Library, Adafruit CircuitPython Nunchuk, and Adafruit Neopixel.
  • The controller currently supports keyboard, mouse, and DirectInput emulation, but it is not compatible with keyboard-to-game-console adapters due to USB composite system behavior.
