Yeah, he catches every single one of those and does it in style. Easily my favorite educational (often retro) tech channel. He gets you hooked even on stuff you already know about. Funny thing: some people have joked that he's my alter ego (I guess we look slightly similar?), but I could never deliver stuff like he does.

Well he did miss one tiny little thing in his toslink video. I pointed it out (and I’m sure others did) and he filled in the gap in a follow-up video. He sets a very high bar. I wish he did have a more technical discussion on CRT vs raster displays. There is a real meat there that is typically unexplored. What is the spatial frequency response of CRT vs raster? What resolution raster do you need to be “good enough” and what kind of interpolation/LPF should be used?

You know, "Building a CRT from Scratch" would be a great standalone educational series. It could hit on everything from making glass, to how to pump air out of something, to coil winding/transformers, to phosphor chemistry, as well as the RF electronics stuff.

    Not the same thing, but you reminded me of this since it's in a similar vein. Ben Eater went through the entire process of building a VGA "video card." Anyone with a basic understanding of logic circuits has enough background to understand it. Worth a watch.
