DIY simulator steering wheel and pedals

Hey! I am not a huge game fan, but sometimes I play with the DIRT Rally and some other games, so it was the motivation for me to design and build this wheel and pedals. In the future I am going to make a video about the building process. Furthermore I want to design and build a shifter and some other stuff too. If you interested about it, please follow me.

Some information about my wheel and pedals:

Based on this software:

DC motor: Denso 45200 05271 from a Toyota
Power supply: 12V, 40A
I used 2 BTS 7960 motor driver in parallel
Drive ratio: 4:1 with HTD-5M (25 mm width, pulleys: 60 and 15)
Encoder: OMRON E6B2-CWZ1X
- Mainly I used aluminium for the frame and steel for the shafts.
- I wanted to use the least amount of cable, so I used slip rings for the shifter paddles and the buttons on the wheel. With this solution does not any limit the number of wheel rotation.
- It can produce more than 20 Nm torque on the wheel.

The paddle shifters: Yes I know, in this video there are in a wrong place. When I made this video it was among the first tests and I have never used a paddle shifters earlier and this layout seemed comfortable to me.
Later I changed the layout to the standard.

Thank you for the reading and watching! :)
