Ben Krasnow's Applied Science - Teaches a lot more than electronics, but will also help you get some ideas (don't underestimate watching people do cool stuff to inspire you)
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.
