The beta continues its progress, with many, many developments. We are currently in the process of modifying the heart of the gearbox: light on the biggest update since the launch of the beta!

The heart of the gearbox : the guide!

The guide has two roles: to guide the lever on the H-grid, and to host all the electronics, namely an arduino board and 6 Hall effect sensors. It is the only component that had not evolved until now. It has just received a major update. This update required a lot of work because it was necessary to completely redesign the part on Fusion360, which I didn’t know.

Optimization of the wiring :

The wiring is now a little cleaner: the cables coming from the Hall sensors are all grouped above the pins where they plug in, the ground no longer passes over the board, just like the wires for the sequential. This saves space, especially for the installation of the mod button plate, or the pedals.

Shift optimization :

The “H-grid” part has been reworked to facilitate shifting from 2 to 3 and 4 to 5. The beta testers had several versions at their disposal.

New “Crank”

The whole moving part of the mechanics is mounted on the “crank”, so it is a component subject to many constraints. And despite numerous optimizations, it is impossible to achieve something perfectly satisfying in terms of solidity, the difficulty being to ensure the perfect maintenance of smooth axes by clamping.

I am therefore integrating metal parts that take care of the clamping of the axes. For the moment, the first tests are very conclusive: the axles do not move at all!

Towards the end of the beta?

Yes, we’re moving very fast towards the end of the beta, I don’t think it’s necessary to make any further changes afterwards. Besides, I’ve already started making detailed videos of the editing.

I've been passionate about cars since I was a kid! I learned the multiple variations of the Skyline R34 through the Gran Tursimo series, until I discovered GTR2 at the wheel of a keyboard. A few years later, I plunged back into Sim Racing with a G27 which made me enter the DIY world. Always looking for an immersion out of reach in reality, I develop projects that I take care to make accessible to any 3D printer owner!
