I got tied up with other projects while I was trying to navigate the submission process (it was my first time), so it's not up yet, but I'd be happy send you a build if you want to check it out.
Also, what is your recommendation for finding a cheap usable microscope? My brief forays to aliexpress have just resulted in frauds and trash.
This is the one I use. It is surprising good for the price. It just behaves as a regular webcam.
I primarily use it for micro soldering, so your mileage may vary, but it is very good for the price. I got it on Amazon where I believe they have an official store.
