Making logic gates from transistors

This video was reasonably good, but still required a lot of background. If you want really terrific easily understood, yet totally in-depth information about integrated circuits, starting from the physics how semi-conductors actually work at the electron level, all the way up through gates and on to an entire computer, Ben Eater's videos are outstanding. Most people know his work from the Breadboard computer, [link] , where he builds an actual functioning computer, with instructions and microcode and output, from scratch on a breadboard, along with terrific explanations. But that is just the tip of the iceberg. All his videos are amazing, and super easy to understand. Here is his version of how nor gates work: which is way easier to understand to me than this video: ▶ this video Here is his whole channel: [link] and his website: [link]

The thing that blew my mind was how you can replace discrete transistor logic with memory. While it is sort of obvious in retrospect. I think it an important insight into the nature of computation.

Something like that? [link] or ▶ this video and there are truckloads more of these. There used to be electronics sets for kids with breadboards (some of them larger scale for easier physical handling then standard breadboards), and they'd had manuals with them explaining all the things. I remember that they also contained descriptions of basic gates like (N)AND, (N)OR, NOT, plus flip flops for storing 1 bit of data.
