This is just some stuff that looked like it might be interesting but I haven't looked through yet.
So I can't recommend it, but i don't want to forget about it so i put it here.
Photos on the first link looked interesting tho, really makes circuits look like "wizardry" or something.
Except in real life the magic circles and geometry they're drawing (etching/printing) have meaning and do stuff, like make computers work.

some comments from the second link:

If you're interested in this, watch this [1] very in-depth 1943 movie called "Crystals go to War" which documents crystal oscillator manufacturing step by step. Honestly, I was amazed by this. I tend to think of technology as pretty primitive in the 40s but this is a great reminder of how sophisticated technology could be even back then.

That's an amazing video. I was surprised by how many steps it took to make a crystal. Also noteworthy is how many different tests and checks they did on each crystal.

The technology is an interesting mixture of sophisticated and primitive. On the one hand, they had X-ray machines to determine the crystal alignment, and lots of specialized mechanical and electronic machinery. On the other hand, people were spooning abrasive out of a pot with a dinner spoon. Everything was very manual and labor-intensive, with no automation. An interesting mix of highly-skilled precision labor and low-skill tasks.

Would be very interesting to see a current-day behind the scenes video of 2021 manufacturing process and compare to 1943. I wonder how many humans touch current day crystals. In the video it’s at least at least a dozen.

I found a video of modern quartz crystal manufacturing. It doesn't have explanation, so it's basically fancy high-tech machines doing mysterious things: https://www.youtube.com/watch?v=Own-5Qz_vSs

It's interesting to compare the scale. In 1943 they were packing a box with a few dozen crystals, while the modern manufacturer fits probably 18,000 tiny surface-mount crystals in a box.
