Aside from his basic 8-bit CPU, Ben Eater goes into how transistors work too: ▶ this video . Once you've got transistors, his videos walk you through making gates. Once you've got gates, he switches to the 74xx series and builds a CPU.

Great explanation — although only a week or so ago I wouldn't have understood a lot of it. Knowing how transistors work helps a lot: ▶ this video
