Reddit mentions of Practical Electronics for Inventors, Fourth Edition

I'm entirely self-taught in radio and electronics. It's totally doable. I started as a kid because my grandfather was a ham radio operator and electronics tinkerer and I loved the stuff he had in his basement.

Many of the resources published by the American Radio Relay League (the ARRL) are geared toward hobbyists and (unsurprisingly) amateurs. They contain just enough math and theory to get you to where you need to be to understand how stuff works without going deep into RF / electrical-engineering math. The ARRL Handbook is a classic that's been around for decades and is updated every year.

Another book someone recommended to me ages ago is Practical Electronics for Inventors. I've never seen better explanations of electronic theory and basic circuits than I've seen in this book. I can't recommend it enough. If you buy only one book, I would make it this one.
