Thanks to this comment, I've now spent this past weekend binging the entire Ben Eater 8-bit computer series this far. Very entertaining, and I certainly learned a few things about computer architecture. I'm very tempted to do the project myself.

There is a very, very base level of electronics understanding for a couple things that are below the scope of what he covers. You're expected to understand what a pull-up resistor is, for example, and he briefly touches on RC circuits but I don't think his explanation would be sufficient for grokking the concept from scratch. Overall though, he is an excellent teacher and I think he makes concepts quite clear.

I personally ran a few parts at 2x speed, and skipped the Turing machine discussion entirely, but I'm sure the info is quite necessary to some people, so I'm glad he included it all.
