Not really sure where to ask this, as even the Google answers are very confusing for me.
I’m interested in DIY consumer(?) electronics. For e.g I saw a video of someone buying a used tablet screen, a display board, and made himself a little portable monitor. Or I have a retro handheld, and some people open theirs up, and replace the speaker in it. They buy the actual little tiny speaker from China and put it in themselves.
This stuff is cool as hell how do I learn how to do this?? I know I can look up project guides and recreate them, but I’d eventually like to be able to do my own things (like if I want to make some kind of soldering change?) And I assume that requires more in depth knowledge.
I should also add I have absolutely 0 prior knowledge about electronics.
Basic electronics: Adafruit or Sparkfun tutorials might be a good place to start?
I guess you might want to start with understanding not only Ohm’s Law and resistors, current, and voltage. Then learn Kirchoff’s Voltage and Current Laws because it helps with even rudimentary circuit analysis and design. Then learn about charge and current and what it is exactly. Because once you do, you can use that to understand how capacitors work at a basic level. Next learn about inductors and how magnetic and electrical fields work at a basic level. If you plan to mess with audio or any kind of signals you would want to get an idea of impedance and AC signals so you can understand filters. I suppose you can then learn about semiconductors starting with diodes, then LEDs. Then BJTs, followed by (maybe) JFETs and MOSFETs (all different types of common transistors). If all you’re doing is using these as switches that’s not too hard. I would save transistor amplification topics for later. You could learn about op amps next. They can be quite useful. If you get that far you probably know what you want to learn about from there.
I learned all this and more in college back before the web existed so I have no idea if there are any good video series out there or not. If there isn’t maybe I oughta put something together lol.
