Very cool, but I wonder how far you get with something like this: https://nl.aliexpress.com/item/1005004262524839.html
It's not motorized and motorizing that type of stand is painful (there is at least one paper that shows it's possible; I tried it and the results were not great: https://journals.plos.org/plosone/article?id=10.1371/journal... )

What was the biggest challenge? I suppose you get some unpredictable backlash in that flexible shaft.
Instead, i switched to cloning stages like this: https://www.asiimaging.com/products/stages/xy-inverted-stage... but I used off-the-shelf (well, amazon) linear rails, off-the-shelf (stepperonline) steppers, and 3d printed (or machined aluminum) frames. Works much better.
Related cool diy-ish optical stuff... A friend sent me this simple design for a raman spectrometer [1]. And some 3D-printable cage optics for when alignment is really important [2].

It seems like an ESP32 camera could handle everything pretty cheaply, why is this not a thing you can just buy for $50 on Amazon yet?
