If you remember the various 74xx series gate families (H, L, HS, LS, etc) you’ll probably be as fascinated as me by this Curious Marc video deriving the gate families from first principles, starting from diode-resistor logic and working forward. Both gate schematics and practical breadboard demonstration of each variant, with an explanation for what the new variant is fixing in the older variants. (28 minute video, released today.) https://www.youtube.com/watch?v=wdn024FdUFg
