First test of my openffboard build with power (vimeo.com)

A quick test, without a wheel attached to the spindle, of the openffboard running on Linux in BeamNG.drive. It took a while to get here as I'm not very knowledgeable with motor drivers but it seems to work so far.

Next step will be to fabricate a bracket to mount it to my rig. Since this video I have mounted a wheel and done some driving. The feel is pretty good, the motor is only 6NM which in DD land is a little on the low side but it's incredibly smooth.

Hardware:

OpenFFBoard (purchased assembled)

ODrive S1

Baldor BSM90N-1150AFP (ebay auction for untested motor, was about 50USD shipped)

48v 10.5A power supply

Nice! I wish I had the space for a motion rig. That sounds like a fun project.

What motors are you looking at?

Honestly I have a Poang chair from ikea and I was thinking about using windshield wiper motors like this fella did. https://www.xsimulator.net/community/threads/ikea-1-5-dof-ultra-comfort.5602/ I think it would be a great entry level start then Ill maybe move on to actuators and big boy stuff.

LOL, that's amazing. I have one of those chairs which is currently piled with extra blankets and no one has sat in it in years. I may have to give that "1 DOF of relaxing movement" a try too! Even if I have to drag it out of the way when not in use. That's a much smaller footprint than what I was imagining for a motion rig.

I really like it and I think I could hide all the guts underneath the chair when its all said and done.

I really like mine. Its comfortable for long races. I did brace the chair so at the moment mine doesnt have the rocking effect. Here are some pics for a couple months ago when I got my g29. https://imgur.com/gallery/9kkFi4T
