Direct Drive Open Sim Wheel Sim Racing Bay

Introduction

I had started to build my own DD wheel back in France, 3 years ago. Since, I moved to Singapore and now the electronic system I chose is deprecated. I chose a Granite Device VSD with a STM32 with MMOS firmware. The MMOS firmware is not updated anymore and the Mige I bought don't have the latest Biss-C encoder. Upgrading to SimCube electronic and ship the heavy motor from France would be more expensive to buy a new whole kit from SimRacing Bay.

Installation

Wheel Plate mounting

The installation was super smooth and worked without any problem after the firmware upgraded automatically when I plugged the electronic on the PC. It's plugged through a USB 3.0 Hub as I will need it for the pedals, shifter and VR Headset.

To install on the Playseat, I had to drill 4 holes in the wheel plate. Surprisingly the whole thing is more steady than I thought it would be.

Wheel Plate Rigidification

The plate is very steady in torsion, but would need more rigidity vertically. So I created a rod to connect between the wheel plate and the seat. Using camera mount and a 22x22mm Bosch profile.

Here's a video showing the improvement.

I updated the bar to ridify the wheel mount, I use a professional clamp and a aluminium profile bolted to the plate.

This method is still not good enough, where the profile is actually fixed is in the middle of the Mige motor which create to much lever. So I end up with a solution that as no flex at all except the whole cockpit flex.

SimuCube Mounting

I mounted the SimuCube box on the seat itself so it is easier to move the seat folded and unfolded. And also I can do some cable management once the Simucube is fixed to the seat.

I used 500x30x3mm aluminium plates. I threaded directly on them to fix to the Simucube back plate. Then I used 2 smaller plates to pinch in sandwich the seat's tubes. Once the seat folded the pedal comes just above it, no worries about that hopefully.
