When it comes to controllers for racing games, there is perhaps no better option than a force feedback steering wheel. With a built-in motor to push against the wheel at exactly the right times, they can realistically mimic the behavior of a steering wheel from a real car. The only major downside is cost, with controllers often reaching many hundreds of dollars. [Jason] thought it shouldn’t be that hard to build one from a few spare parts though and went about building this prototype force feedback steering wheel for himself.

Sourcing the motor for the steering wheel wasn’t as straightforward as he thought originally. The first place he looked was an old printer, but the DC motor he scavenged from it didn’t have enough torque to make the controller behave realistically, so he turned to a high-torque motor from a battery-powered impact driver. This also has the benefit of coming along with a planetary gearbox as well, keeping the size down, as well as including its own high-current circuitry. The printer turned out to not be a total loss either, as the encoder from the printer was used to send position data about the steering wheel back to the racing game. Controlling the device is an Arduino, which performs double duty sending controller information from the steering wheel as well as receiving force feedback instructions from the game to drive the motor in the steering wheel.

After 3D printing a case for it and strapping it to a work bench, the initial tests proved to be promising. [Jason] can feel the motor from the power drill pushing against the steering wheel at the appropriate time. However there are some issues to work out with the prototype as the coupling mechanism between the motor and steering wheel isn’t strong enough to resist skipping and is likely to eventually break. We look forward to future videos when these issues are ironed out, but in the meantime we’d recommend taking a look at this force feedback mouse for other ways of making video game experiences more immersive.

We've seen attempts at recreating video game racing in real life. For Artica and The Arcade Man, there's no desire to preserve the illusion -- they've jury-rigged two Sega Rally cabinets to control the strictly real-world racing experiences of RC cars. Their two-machine setup from the recent Codebits VI event in Portugal yanks the original arcade computing power in favor of an Arduino-powered system that maps the steering wheel and pedals to the tiny vehicles through a wireless Xbee link. The setup does make a nod to traditional video games through the cameras, however: drivers can pick either an arcade-style overhead camera or jump to a cabin-level view. The only true challenge during the build process was to find viable displays for the rigs, as the original CRTs proved too problematic for the retrofit. Some might consider it sacrilege to gut a classic cabinet for the sake of some RC action, but the end result is a racing experience that's at once very familiar and yet surprisingly fresh. Spectators had better watch their feet, though -- the competition might get fierce out there.
