Development of the Open Sim Wheel “full kit” direct drive steering wheel

Remarkable how quickly the rise of the Direct Servo Drive dubbed OSW – Open Sim Wheel – came into being, thanks to its founders who really put their hard work into the development of the hard-, firm- and software. It’s about to take the sim-racing world by storm.

Check out Marcush Wang’s Open Sim Wheel blog here, and Michael Aschers blog here.

For the DIY’er that is confident enough there lies the challenge to build and sourcing parts on its own. Some complicated wiring has to be done, flashing of firmware, settings to be dialed in, a long intricate list of parts needed to bring the servo motor alive.

For the more casual sim-racer, there is the all-in-one solution. A complete kit based on the SIM-ple board that integrates several electronic parts into one ready to be plugged-in PCB. No more difficult to understand wiring diagrams, diodes, return currents that might burn your costly IONI drive to toast. Just a kit that needs to be hooked up with the cables supplied with it. And the goals is to make it even better.

With several parts in the works, sim-pli.city is looking to optimize the design and add features along the way. The first step will be integrating the PCB into a standard ITX-case. With the help of some custom brackets and I/O shields designed by Sim-Lab, we hope to deliver a neat solution for the coming batches of “full kits”.

While the simple board will fit in every mini-ITX case, as it uses the standard mountain points of it, the Cooler Master Elite 110D is one of the options to be delivered with the full kit. A custom made I/O shield will make a tight fit around the connectors, the PSU plate will facilitate an extra fan mounting point to keep the inside cool and your OSW delivering breathtaking Force Feed Back without breaking a sweat.

And that the OSW isn’t really troubled by anything a simulator can throw at it is a breakthrough on itself. It makes sim-racing a more immersive experience. Currently, the MiGe 130ST, referred to as the “small mige” is out to set the most popular of the bunch. With 20 Nm of peak torque at its disposal driving at Sebring will not quite be the same again.
