If there is anyone here interested in learning how computers work and then building their own computer, I recently discovered Ben Eater on YouTube (https://www.youtube.com/channel/UCS0N5baNlQWJCUrhCEo8WlA) who has made an 8-bit breadboard computer and is working on a more advanced type.
Kinda related: I also found a site called “Dave’s Crystal Radios”, so if you’re truly looking to become more independent, you might try your hand at making one: Dave's Homemade Crystal Radio Projects and Plans Main Page.
