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, and that’s what really matters for the long-term sustainability of these projects.In the meantime, I’d like to share a small project that may not look like much, but on my rig it genuinely changed my experience. It’s quick to make, inexpensive, and...
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 works (once the new firmware is flashed):Engage 3rd gear, press the lever into reverse, and plug in the gearbox → you are now in calibration mode!Return to neutral, then shift to 3rd or 4th gear to decrease or increase the locked position.Press the reverse switch to test the lock...
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 gearbox is already printed, you can replace this lip with an M5 washer.Seq holder RHD: a small piece of plastic was sticking out.Body2 get rid of a feature that was canceled below the carriageMajor cleanup work on my side to remove duplicate functions, fix errors, and completely reorganize th...
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 to V1.3.Finally, I'm offering all PRO contributors with more than three months of contributions a €10 discount if they wish to order PCB V1.3 on the website. I've just placed an order for 10 units, which can already be reserved (shipping...
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 clearThe main subject of this update is the sequential. We keep the idea of the previous update: a single switch, and a longer stroke. On the other hand, we change the switch, we need these roller switches which are bigger (and are therefore more tolerant to printing deviations):https://amzn.to/4hfz1eg(if you place an order on the store, I can slip you one... )I'll see next...
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 been like that for so long... The almost good news is that I am starting to have a functional workshop. I say almost because the work in the basement is no longer progressing and the workshop is in the office that I should have shared with my wife... We...
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 for processing orders, and I’m setting up a showroom and a space to test prototypes.Still, that hasn’t stopped us from refining our beloved V10. Let’s get into it!Updates:No Turn update:The No Turn had a minor weakness with the fastening of the upper bea...
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 a pleasure to bring together again under the same roof the simulator, the machines and the CAD workstation!!!However, I "lost" a lot of time, and I propose for this November update half of what I had planned...1) Crank FixI noticed t...
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 sliderThe biggest problem encountered concerns the tracks: they ultimately do not stay in place in the slider… the tolerances being too variable from one printer to another, the current solution cannot be retained.Many of you have requested the return of a retaining screw. This solution does not really delight me for several reasons:it requires modifying the shopping list and therefore the screw ki...

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 been validated for some time. The gearbox is reliable, and adjustments are made at the margins to optimize assembly and printing.2) I've already started shooting the assembly videos. Compared to the V9, the V10 is so easy to assemble that it sh...
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: https://www.etsy.com/fr/listing/1737587527/pcb-boite-de-vitesse-srt7€ instead of 15€. They include a dedicated socket for the eClutch, see photo.In parallel, I've just uploaded RC14 code that fixes a bug in button plate feature 4 (invert). Still available...
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 better understanding of the problem, and I've come to the following conclusions: 1) the magnet's detection zone is very large, even with a small magnet. 2) although the detection zone is large, the magnet still has to pass in front of the ...
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 experienceImproved communication with SimhubMore complete status messagesStand-alone code: can be loaded with any Arduino IDEPlease note that the code to be entered in “custom protocol” is different.As usual, the code is available on the website :https://lebois-racing.com/exclusive-firmwares-for-pro-and-elite-patreons/The new PCBs for the HSS gearbox mod will arrive early this week, so keep your fingers crossed!
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 various magnet configurations. It's better, but still not perfect. So here it is, for those who are wondering: I'm going to order a new PCB with hall sensors a bit further away, hoping it'll be good this time... Translated with DeepL.com(free ve...
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) Some mods are too complex to be used, like the pedal mod with ADS1105...2) Some parts of the code are no longer of interest, like the SmartSequential mod I developed for PCars2.3) The arduino we're using is too slow to handle many mods (especially pedals, where spee...
SRT80 V2
V2 ? Let's calm down right away: it's mainly additional files:addition of two motor mounts with integrated fixed bearingaddition of a linear bearing mount with "compact" easy mountaddition of an updated slider for raw aluminum profiles delivered a few months ago.As usual, available on : https://lebois-racing.com/exclusive-files-for-pro-and-elite-patreons/
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 better treatment, and those tests helped me to understand what we need to do to make it great.It meant to upgrade the design of the carriage, the slider, and the sequential track. So please try them together.Recent tests with a 4x2mm magnets with the pcb ...
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 the code to gain speed, and adjusting the position of the magnet in relation to the PCB, we should be able to fix the problem.I'll post a message here when the problem is solved. If the problem has to be solved by changing the PCB, I will of cou...
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-and-elite-patreons/Please also note that the required PCB is out of stock. Second batch should land in 10-15 days, you can pre-order here :https://www.etsy.com/fr/listing/1687146293/kit-mod-hall-sensor-sequentiel-pour?
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 here: https://www.etsy.com/fr/listing/1687146293
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 mod in less than two weeks.See you soon!
