OSW

Motivation

After a lot of problems (defective contact, FFB loss and USB loss) with my Fanatec CSW v2 wheel base for the fourth time this year I was searching for a more roboust solution. After my research and some wheel comparisons the idea to get a direct drive wheel was born. So I started a small project for the Open Sim Wheel including the modifications for my existing Fanatec wheel rims to reuse it with Fanaleds.

Orders

The order for the wheel base (direct drive unit)

I ordered a SimuCUBE based OSW kit with CM110 case at simracingbay.com including the Fanatec Quick Release. After 2 or 3 working days I got the package and previously I got a manual (incl. videos) for the setup process.

The orders for the modification of the Fanatec wheel rims

I ordered a Teensy LC, 8 pin mini/micro connector and an USB spiral cable for each of my wheels.

 

Setup Fantec Wheel Rim(s)

Step 1: Disasample the wheel rim and flash Teensy LC

Step 2: Solder the cables

Step 3: Connect it to your PC and test it with Fanaleds

Step 4: Isolate Teensy LC

Step 5: Stow everything in the wheel rim and assemble it

 

OSW Setup & Conclusion

The setup of the OSW kit was really straight forward thanks to the well prepared guideline from simracingbay. The result is just awesome. The feeling for the car is more precisely that your able to fathom the limit range in a broader way and Fanaleds is running with the modified wheel rims as usual.
