I've built stuff with microcontrollers (partially aided by techniques learned here), but that was very purpose-driven and I'm not super interested in just messing around for fun.
I’m having trouble wrapping my head around how / why you’d use youtube to present analog electrical engineering formulas and pin out diagrams instead of using latex or a diagram.
The best compromise seems to be webpages with readable technical info and animated video illustrations - such as the one posted here yesterday about how radio works.
There has been a lot of times where I am showing someone new to my field something and they stop me before I get to what I thought was the "educational" point and ask what I just did.
Video can portray that pretty well because the information is there for you to see, with a schematic or write-up if the author didn't put it there the information isn't there.
