Everything is packed in the archive : 3D STL and STEP files, pictures, shopping list.

Merry Christmas !

I would have loved to wrap up the year with a big update — something bold, something with real punch. Unfortunately, I’m still missing a bit of time before I can share news about the major projects. Things have clearly slowed down lately, but at least I’ve found a good balance in my life, a...

SRT Gearbox : eclutch update

The automatic eClutch calibration caused more problems than it solved, so I’ve added a manual calibration procedure directly integrated into the main firmware!
No more flashing a different code, no need to open the Serial Monitor or type any commands.

Here’s how it w...

SRT Gearbox : August Update and news

This month, it’s a minor update, which doesn’t really reflect the mountain of work completed over the summer.
The update boils down to:

• No Turn fix: the upper bearing lip (highlighted in blue on the image) had been missing since the last update. If your gearb...

Hello drivers !

---- PCB V1.3 ----

Many of you have complained about having to change the PCB. I'm sorry the first version wasn't entirely satisfactory. I remind you that the latency is really minimal; owners of PCB V1.2 who don't plan on using sequential mode should try it out to decide whether to upgrade...

SRT Gearbox : April Update

The April update is available! New PCB (v1.3), new firmware, 3D fixes, everything is detailed on the site:

https://lebois-racing.com/srt-gearbox-april-update/

SRT Gearbox : March update!

Basically, I thought it would be a small update...

...

Not at all...

Come on, let's stick to it with a nice clean log that no one will say boooouuuuu it's not clear

The main subject of this update is the sequential. We keep the idea of ​​the previous update: a single s...

SRT Gearbox : January update!

Here we are in 2025 and the 4th monthly update of the SRT V10 is online!

As you probably know if you follow me on Facebook or Insta, the second tiny driver has arrived in the family. I would like to tell you that it is getting harder and harder to work. It's true.... at the same time it's b...

SRT Gearbox : Décember update!

Here’s a new batch of fixes and optimizations for the final month of 2024!

Another very busy month... maybe too busy... As you know, we had to temporarily pause the store to reorganize. So, Max and I are both handling separate projects at the same time—Max is preparing his new workshop ...

SRT Gearbox: November update!

That's it, I moved! Well for the moment it's the construction site... I thought the workshop would be operational quickly, I realize that it's quite the opposite! So in the meantime I received permission from my wife to spread out a little everywhere in the house, developments are resuming. What ...

SRT Gearbox : October Update !

The first gearboxes are assembled, and the first feedback is very positive. However, you have reported some problems that this update fixes.

1. New slider

The biggest problem encountered concerns the tracks: they ultimately do not stay in place in the slider… the tolerances b...

UPDATE: The 3D files have been updated on the site:

- added files for the button plate mod
- body2 and servo support fix for the RHD mod
- added RHD logo on the parts for the RHD mod
- added a mount for the handbrake mod on body1
- added the mounting plate for the handbrake mod
- added the complete step files for creators

On ...

The V10 is alive !!!

I really hope that you will like the new improvements.

Just few of them :

• Auto-calibrating eclutch

• Single magnet design

• Integrated hall sensors

Hello drivers ! 🏁

The V10: when?

Bad news: I'm off on vacation soon... yes, how awful... Well, we'll console ourselves by remembering that the V9 was designed while I was on vacation, proof that it's not a sandy beach that's likely to put the brakes on developments.

Here's where we stand:

1) All the principles have...

SRT Gearbox V9 : it's OVER.

HSS mod canceled

Further to the previous survey, I hereby announce the cancellation of the HSS mod. The documentation will soon disappear from the site.

Please contact me on Etsy to request a refund for the V1 HSS PCB.

I'm taking this opportunity to destock the new PCBs that will no longer be used: ...

Should the HSS mod be cancelled?

As you're probably aware, the HSS mod was quickly found to have a fault when it was released over two months ago: the gears don't shift fast enough, if at all.

So for over two months now, I've been multiplying prototypes to remedy the problem. As my tests have progressed, I've gained a bet...

New firmware for the Smart Control Box on the P1 harness tensioner!

The new code is derived from the GForce:

•  Faster execution times for a more accurate experience

•  Improved communication with Simhub

• More complete status messages

• Stand-alone code: can be loaded with any Arduino IDE

MOD HSS: news from the front line

Time passes at a frightening speed. One day, you launch a mod and a piece of shit appears. We tell ourselves it's just a question of adjustment.

And two months later, it's still not fixed. I received the latest version of the PCB two weeks ago. I must have tested a dozen sliders with vario...

RC 13 firmware for the SRT gearbox: the code of maturity

Maturity! A big word indeed!

The V9.1 gearbox is getting old. The community has grown, and so have I. I've been able to observe which mods were used, which were usable, which were unusable.

When I recently reworked the code to make it lighter, I became aware of a few things:

1) ...

SRT80 V2

V2 ? Let's calm down right away: it's mainly additional files:

• addition of two motor mounts with integrated fixed bearing

• addition of a linear bearing mount with "compact" easy mount

• addition of an updated slider for raw aluminum profiles delivered a fe...

End of HSS V1.0

Ok, so I've worked hard those last days trying to fix the issue mentioned earlier. At this point, it seems clear to me that the magnet should be as close as possible to the sensor, and as small as possible.

I took it as an opportunity to work again on the sequential behavior that deserves a...

Mod HSS

I did many tests with 8mm and 6mm magnets but it wasn't conclusive.

I'll get 4mm magnets this week-end, I hope that it will fix things.

Houston we have a problem

It seems that I've sunned by overconfidence. As highlighted by FredyP on Discord (whom I thank), when shifting gears quickly, the HSS mod doesn't respond fast enough.

I've been looking into the problem since Saturday and hope to come up with a solution as quickly as possible. By modifying t...

Minor fix

The wiring solution was missing on body2. It's fixed now for both LHD and RHD versions :

https://lebois-racing.com/exclusive-files-for-pro-and-elite-patreons/

RHD mod now compatible with HSS

As requested, I added body 2 and slider with Hall Sensor Sequential and Right Hand Drive mods. Files are as usal located on the website :
https://lebois-racing.com/exclusive-files-for-pro-...

The new mod: Hall Sensor Sequential

Here's the mod that corrects one of V9.1's biggest flaws: the sequential sensors. 

It replaces the switches that tended to break with non-contact Hall sensors. 

You'll need to reprint body2 and the slider. 

The PCB can be ordered h...

New mod for the V9.1

A new mod is on the way for the V9.1 gearbox! 

I'll let you know what it is shortly, but for those of you printing, the body2 and slider for this mod will be different.

The current shopping list remains unchanged. 

I hope to release the...
