Showroom DIY force feedback steering wheel, using DC motor. based on MMOS

it jumped because my psu cant handle 100% power needed, thats why i assume the result is 2kg....my psu already old, it cant handle full load in long time, burst only...the result jump to 1.9+kg because the voltage have little bit drop....

Wow new wheel is a lot stronger!
Are you using htd 5m for pulleys? They look like they are 3d printed.
Did you have a lot of problems attaching that pulley to your motor?
I have a car cooling fan motor which has ~0.75 Nm at max power and have trouble attaching pulley to it, the thing is totally round.
Btw my wheel picture is a complete joke. Htd 3m motor pulley (super glued) is skipping teeth and whole construction is flimsy. It will probably have to go to htd 5M

more update...

this is me test the motor driver bts7960/ibt2, its obviously can deliver high apms in my experience...


but you must concern about voltage and temp, its little bit sensitive...

its safer around 22v or lower...
in my setup, i use 18.8v...

@ahoenksiluman , since your encoder is 2 phase, did you leave the pin on stm32 board for z-phase/index unused or is there some sort of hack like they use a switch if using arduino leonardo? can you please share the wiring of encoder?

If you don't have index leave it disconnected and deselect the option in mmos. PA0 and PA1 are pins for A and B outputs, plug them reversed if you wanna reverse encoder direction.

Thanks to confirm this.

Hello @ahoenksiluman,
Amazing project. Well detailed.
I just have a question about how to implement the steering wheel buttons. I can see that you have used an arduino nano in your OMP style wheel here.
Are you running EMP or MMOS in the nano as well and using it as a separate controller to plug into your pc?
Or else have you connected it to the leonanrdo & running a custom arduino sketch in it?
Could you please explain how you've managed to do it?

Thanks in advance.

Hello sir, which printer sensor you have used?

Hello greetings from Argentina. Congratulations on your work !!

I want to do something similar, a few pedal using 2 potentiometers and a load cell of 50kg + HX711 in brake, you think you could work using EMC following the tutorial of EbolzMagy ??

recent time i make more mod for my DIY pedal, i give it hall sensor but i make it in potentiometer form. so it plug and play if the pedal design build for potentiometer.

this is some vid how i make it...

Halo, what happened when you used bts7960 ga523? I built my steering wheel but I'm finding the FFB very entering compared to the logitech g25.

what motor are you using ? what's it's power and voltage ?

Are using the motor as a direct drive wheel or using it with a reduction pulley for more torque ?

What is index here, please tell me little bit I am new
