This is the sort of thing that is solid gold for a well-motivated hobbyist. Lots of content together in one place that takes a (I hope) coherent journey through the "what's important" of a subject.

If anyone knows of something similar for mechanical engineering I would be very interested. (Thanks in advance from a physicist who should probably have been an engineer instead :-) )

This reminds me, off topic but I once found a YouTube channel or playlist of this African women teaching how to read. Apparently a lot of African women can't read and she wanted to solve the problem by making a video course to teach them. I can't for the life of me find it, when I search its either kids ABCs videos or TED talks about empowered black woman authors. I wonder if any video course aficionados might know what channel I'm talking about.

An hour-long video on the PN junction... This is going to be good.

So, this course seems to be about going into the depth, I guess the chemistry and physics, of solid state electronics. Diodes, transistors, etc.

But do I need to spend 45 hours watching this to empower me to successfully design, say, a microcomputer board? A Z80? 6502? Even an 8088? Do I need this level of depth to get a microcontroller to make a stepper motor do what I want to do (whatever that may be)? Or a power circuit to drive a higher power motor controller? (Do I need relays for that? Power transistors? Big capacitors?)

Because that's what I think many who are interested in "electronics" want to do. Will the lack of understanding of a PN junction cause those kinds of projects to fail? Or be more difficult to do?

For someone interested in these kinds of projects, is there a better place to put 45 hours of study? Perhaps just wiring stuff together, stamping out fires, and tracing down the smoky parts?

Is it this channel?

Here is the reading/writing playlist: https://www.youtube.com/playlist?list=PL9RaD1SLwSoZhMNz7pqRw...

I like her pacing (not fast, not too slow) and the way she presents herself. It seems like a high quality course, even if the audio and video quality are not perfect. I wonder how we could bring more awareness to this great work and others like it.

I'm a chemist who should've went for Informatica (computer science) or Ingegneria Informatica (computer engineering) too, I can relate.

While I don't think that a degree would've added much to my professional life as I learned what I wanted/needed I can't but say that chemistry gave me even less (aside of being generally good at theoretical and practical sciences).
