DIY active seatbelt tensioner

Hi all,

I'm Paul from the Netherlands.

After selling my playseat with t500 rs 2 years ago i got back into simracing with a new rig see further for the details.

I'm building an active seatbelt tensioner and motion for the first time its a project to start and when its working fine and i know how to program it i will start building a 3dof.

The mechanics are finished i start with one steppermotor nema 23 i can alwas upgrade to two of bigger motors.

I have for electronics:

Arduino uno
Tb 6600 microstep driver
nema 23 stepper motor 3,5A
LRS 50 powersupply 12v max 4,5A

I run the simtools software

Now i only need a code for the arduino to start with and i have no idea where to start is there anyone that can help i'm good in mechanical work but programming is another thing.

For my rig i run:
-80-20 simlab gt
-lcd seat
-sabelt 6point harnes

-Fanatec csw 2.5
-Fanatec csl elite pedals with loadcell
-Fanatec p1 rim

-home made seq shifter (feels really good and mechanical i wil make a thread from the build)
-home made handbrake (button operated for now but wil update to loadcell in the future after i learned to program)
-home made 7 and reverse Hshifter (feels really good and mechanical i wil make a thread from the build) its based on the Frex h shifter design)
-home made dash from old sony phone running dashpanel and build a nice case around it

-Msi 27inch 165hz screen
-home build pc specs:
*Gigabyte X570 gamingX
*AMD Ryzen 5 3600x
*Corsair 850w
*Gigabyte RX5700XT Aorus 8G
*Samsung SSD M2
*2x 16GB 3200 RGB pro veng.
*Cablemod sleaved cables
*NZXT Kraken x63 watercooler


I hope someone can help me getting started with the programming.

I hope so

Hi. Nice rig. I will be watching your thread. For now I try to do belt tensioner with DC brushed motor. But I have some problems. I also wonder how it's working with stepper motor. Good luck

I had al lot of these Parts i had already so thats why is try steppermotor.

made a test board this evening so i can start testing

@Krzysztof Dej what problems do you encounter?

Wow. Can u show whot is this controller and how u wire it from motor to arduino? Why these switches is for? My problem was that motor caused a short circuit when I mount it on rig somehow. Now I'm waiting for 3d printing part to separate it from rig. But I see now I have another problem with Smc3Utils config. My 2dof motors config doesn't work with this small motor. So I see i will have a lots of play with it

The controller is a bt6600

the Wiring is not ready yet i’m going to figure it out today and try To write a code I Made the switches because i can do Some testing (basics) i never wrote a code before the black switch on the left is for cutting powersupply with one toutch just in case.

Wen i figured out wiring i write it here

This is the controller

I think you should use 2 stepper motors
because it will not be strong enough to give you the sensations you are looking for.

must think:
small speed equals big force
high speed equals small force

for example the one I made.

It's easy for me to upgrade but for now i first need to get it running i never programmed/write code before so when i know how to do that i can modify it in 2/3 hours to a double motor setup

@hoyang i watched your project looks really nice can you help me with code and wiring to get started.

Little update,

I orderd ibt 2 motorcontroller and wipermotor.

why? Because there is way more to Found About coding and wiring so i think Its an easyer route To start with motionsimulation.

made a Nice electronics box today

Made it possible to mount it underneat the chair

the Wiper motor is on Its way do i hope I can do Some testing this evening.

can i use the arduino code for 2/3 dof and only use it on one motor?

Also Made a Bracket for mounting potentiometer

Oké thnx i’m going to try that Fingers crossed

I have a 10k potentiometer it can spin up to 10turns is this To much of is it possible

Got the wipermotor installed only need To figure out the wiring and ground

Please show how u ground it

I wil take pictures en send them what motor do you have i can compare them

Found it

this is a vw polo 6n front Wiper motor

remove the plate inside then remove the cap and cut 1 wire the one with Some ground on the board dont do it like me i cut them al three so i had To solder 2 back i already cut it here

i got it run in smc3 but the motor wil keep turning one way and stalls
