DD-Wheel with Hoverboard Motor

Yes, I have same ppr. For me also setting the correct ppr made the deal.
I also was thinking of buying a moza wheel.
First fanatec but than I researched and saw that u need an original wheel or hub to make the ffb effect work. So at least 200 € extra.
That's a no go for me. I want to use any wheel I want to. So it's moza.

Still, I want to try the Mks odrive. Perhaps it works so well that I don't need the moza. Someone in discord said he tested both. This DIY and a fanatec. He said fanatec has better effects and stuff, but the DIY is stronger and faster. In latency and max speeds. Also Nm is unbeatable for that price point.

Gpio pins, yes you can connect buttons. AFAIK the odesc has 4 Gpio pins which you need to ground to push them. Also have to activate and set as buttons it in the software. Because you can also use Potis instead of buttons.

Did you download the new firmware + software? The one where you have two exe files?

I'm not even thinking about commercial products, how can i build this with 150 euro, and fanatec sells theirs DD with 700 euros(only the base + pedals and a rim). Yes, i know, industrial servo motor and all, but all of this you can get with a OSW to be honest.
I am not sure about the newest version. Is that available on GitHub ? I did not see two executables..

You should join the discord. There is an extra room for the new version with the link to the new fw + software. It's better now. In my opinion at least.

Thanks! I will try it tomorrow.

Also, Eddy, I tried finding documentation about the GPIO pins on the ODesc board, not much luck. So I'm going to build the Lebois SRT pedals, which uses a hydraulic pressure sensor, and two potentiometers, do you think it would be possible to use the ODesc board as a controller for 3 analog axis? If so, how would I need to modify the firmware? Thanks !

I am not sure if you allready asked this on the discord.
But you can use Potentiometers with the ODESC. It has 4 GPIO Pins which can be configured to be axis with the SW. Don't have to do anything in the FW. It is not like an Arduino. Flash FW and do everything else in the provided SW.

Yes, we ve talked on Discord, thank you!
My pedals are almost finished, will share pictures if interested.
Thanks!

Hello, so im also planning to build hoverbard DD. Can someone give part list required.
STM32 with the correct supported version
What motor controller i can use cheaper than ODrive?

If you choose the odrive or odesc4.2 you will not need another STM, which makes it cheaper in the end.

Hi, welcome!
How cheap are you talking about? You know that there are cheap knockoffs of the Odrive, called ODesc, you can find on aliexpress.
In very rough explanation, you need the hoverboard motor, you need an encoder, there several options here, and you need the controller board.
You need a way to fix the motor to a solid base, I just used the base from the hoverboard, you need a way to mount a wheel to the motor, I used 3d printed quick release, and you need a wheel.
Feel free to ask!

I have made Belt Drive FFB wheel. So parts like Encoder and steering wheel i have. Have also BTS7960 and Arduino Leonardo, but that will not work.
So now i find Odesc, do not know if it will work - https://www.aliexpress.com/item/100...535547!sea!LT!0!AB&curPageLogUid=ot5CbMiX3cSI
Also STM32 - https://www.aliexpress.com/item/330...82ead1f484ab22df91c80e051cc&afSmartRedirect=y
(Do not know if that much cheaper will work, but person who gave the link to this STM32 said, that he bought it for 7$ 3 years ago.)
Thats one cheaper - https://www.aliexpress.com/item/100...936767!sea!LT!0!AB&curPageLogUid=Lk1jCezZXLyL


So do that odesc that i put the link - INCLUDES everything for board to work

If you want to go the route of STM board, you will need 3x driver boards. Hoverboard motors are brushless motors->they work with 3 wires.
ODesc board has everything you need, it takes care of the processing of the force feedback, and drives the hoverboard motor. It also comes with a brakeing resistor.
The product in the first link you quoted is what we generally use, some use genuine ODrive boards. I use ODesc board for the past 2 months.
Good luck !

Im want to use only one motor drive board, so wondering what driver for hoverboard motor is reliable, cheaper than 60-100€

That would be the ODesc board, if you get that, hoverboard motor and encoder, you re good to go!
Good luck!

Do i need STM32 seperate to Odesc v4.2? Or only Odesc to plug n play?

Also do anyone know where to find 56v cheaper than 90€

You don t need any controller board aside ODesc, it takes care of processing and driving the motor.
Good luck!
Also, you might want to join the discord of the project, more inside informations there .

Strange, because someone says - "Do whatever you like, but this firmware doesn't run on that hardware and control a motor with it
The firmware might run on that chip, but then you'll need to buy another motor controller"

So now i do mot know what parts i need at all to run it
