I found this series useful when getting into DC electronics. He takes topics very slowly and thoroughly. He’s also got a series on oscilloscopes and a more advanced multimeter feature breakdown.
Jazz guitar.
The nand to tetris course is very good for understanding the fundamentals of computing. Not just basic python, but the very building blocks of computing.
It starts from nand chips, than you build a ram, rom,cpu, and eventually a computer. For that computer you build a ALU and an Assembly like language. Than a complete operating system and a Basic like language. Than a more advanced language that is more akin to OOP and you eventually build tetris.
You can officially find it here, but it’s a bit clunky UI. You might be better of finding the course on Udemy or Coursera or something.

Biochemistry and Molecular Biology - How Life Works
A lecture series I found on the bay, basically it’s third year biochem.
This guy is very well known already for car audio builds, but this video in particular was nice to have when I thought I destroyed a brand new Focal 165ES K2 speaker. Never gasped so loud in my life as I saw that screwdriver slip straight through the surround.

Busuu for language learning. It’s like Duolingo, but the main difference is that it actually teaches you the grammar, instead of just making you memorise random sentences. It also has some audio and video of native speakers, at least on the Japanese course. And each module ends with a prompt where you freely write or speak your answer (e.g., “What do you like to eat?") in your target language, and then it gets graded/corrected by native speakers in the community.
And for Japanese kanji specifically, WaniKani. Nothing else I’ve ever tried has helped with kanji, but their writing style and off-the-wall mnemonics honestly make it so much easier. And you get the first three levels for free, which is actually tons of content.

Extremely niche, but iidx.org

Nice. Yeah, it’s a fun topic, thanks for starting it!
JustinGuitar is great for sure. It’s a little frustrating that he doesn’t put tabs in the videos - sometimes that would save a lot of time. But you can get those too if you sub I guess. The song lesson library there is also super helpful.
