So, this isn't exactly retrocomputing and it looks like it's from four years ago, but I just found it and thought that many here may find it interesting.

This guy built a simple 8-bit CPU out of essentially discrete logic circuits (from what I've see so far, nothing more complex than a 4-bit adder chip) and explained the entire process.

Hmm, I can't remember now if I've linked the guy doing his own semiconductor etching in his garage. I definitely have elsewhere, and that's kind of similar.

Just in case: Sam Zeloof

He built his first etching setup when in high school,,, after graduating college a few years ago, he ended up starting a company with Jim Keller, the coauthor of x86-64
