(Yes, I remember Forrest Mims (as an author) from "the old Radio Shack days" (where his books were primarily found, back in the day...) He was a great author of electronics related texts. It's nice to see his works preserved online!)
The video referred by the original post is 5 minutes long so I could probably scan the equivalent text in 1 minute. More, I could use a text version as reference, which is a lot more difficult when scrolling about in a video.
No sarcasm here; you asked for some text-based resources and so I listed some that I know to be quality-- Paper copies of these books and some parts/breadboards to tinker with are how I learned the basics of electronics a couple of decades ago. The fundamentals haven't changed.
