Hey OP - if your thinking about a smart knob with haptic feedback etc - check this open source project out that you can build yourself - its amazing:

Oh man, this has been on my to-build list for ages, right up there with the 6 axis “3D mouse” build. I love the attention to detail.

I made a SpaceMouse the other day, it was really easy, mostly just the print. It took around an hour to assemble everything, I think? It also worked very well.

You're welcome! It's a really cool project, and fairly easy.

Ah right, the one I was thinking of was this one which seems like a bit more work... https://www.youtube.com/watch?v=iHBgNGnTiK4

Yours looks great too, though, and it seems a lot more accessible than the fancy one. :)

Ah yeah, that's much more work and I don't think it uses the official driver, which does a lot of the heavy lifting. I think maybe start with the other one and see how you like it, since it's mostly a few minutes of soldering.
