Well, I hit 30 years old and realized I’ve never really tried building anything for myself. Here’s my finished racing cockpit, built to use with an office chair. This is my first time using a miter saw, circular saw, half laps, pocket holes, etc.

My limitations were: it had to avoid a horizontal bar that my desk has in the back, I wanted inverted pedals, I wanted to use my office chair, it had to be short enough to slide under my desk for storage, and it had to be no more than 18” wide for storage purposes as well.

For never attempting anything like this before, I dub this one “far from good, but good from afar.” Don’t make fun of it too much. It’s got some quirks like the wonky cross support, whoops. But it was all a learning experience, and I’m excited to try it out.

Hi everyone,

I'm currently gathering parts to build a DIY Direct Drive wheel using a hoverboard motor. The components I have so far are:

  • STM32F407G-DISC1 (planning to run OpenFFBoard)
  • E6B2-CWZ6C 1000 Pulse Encoder
  • Original Hoverboard Motherboard (planning to use Emanuel Feru’s Hoverboard Hack / FOC firmware)

When I was buying the hoverboard motherboard, the seller warned me that a few people tried this exact project and failed. I think they didn't have enough knowledge but I'm still worried.

I assume the people who failed didn't understand the architecture (using the hacked hoverboard mobo solely as a smart motor driver and the STM32 for FFB calculation/HID), but his comment still made me a bit hesitant.

Before I buy the motor and motherboard:

  1. Is there anything specific I should be worried about with this setup (STM32F407G + Hacked Hoverboard Mobo)?
  2. Are there any major latency or FFB feel issues compared to using a dedicated driver like ODESC? G29 is the only wheelbase I experienced so it would be great if you can compare with it.

Any tips, wiring suggestions, or things to watch out for would be greatly appreciated!
