Ahoy and Mentour Pilot are great!
Probably won't come as a huge surprise that my recommendations will be mostly about history, but I'll start with not-history:
Map Men
Okay, fine. You got me. This is about history. But its about maps more! Stop yelling at me!
Anyway, hilarious way of learning about things like how did France get smaller by measuring it. Most videos are not very long, so perfect to watch while having tea or a quick snack. As a bonus, the channel used to be called "Jay Foreman" (as you can see from the url), and he had a excellent "Politics Unboringed" series about UK politics. Even if you are not interested in that stuff, they are worth the watch just for the comedy value.
DankPods
Garbage Time
James Channel
I lumped these together because DankPods and Garbage Time are hosted by the same guy and Garbage Time has James, from James Channel, doing the garbaging.
DankPods started as a iPod channel, now its mostly about reviewing old and crappy nuggets, mostly mp3 and music players. But also sometimes features comparing computer hardware, for example the whole Linux comparison marathon thing. Headphone reviews used to be a thing as well, but most of the good ones have been reviewed so thats more rare now.
Garbage Time is about torturing cars, like using Vegemite instead of engine oil, or mixing pepsi and milk to make pilk and using that as a engine coolant. Also features fixing cars, unfixing cars. James is a trained car restorer, so they do have a bunch of serious content.... but they also have stuff like using house paint to paint a car.
James Channel is the car mechanic from Garbage Time, its similar to DankPods, but instead of old music players, its old gaming consoles, handheld stuff and normal consoles. Also fun stuff like making a SNES-PlayStation or making a NES cartridge play a NES cartridge, making portable, handheld Xbox or Play Station.
Mossy Earth
Rewilding projects. From restoring a Scottish river, to turning a old quarry in Portugal into a wetland/pond area. Building coral reefs in Indonesia. Doing forest stuff in the Amazon... This is a amazing, inspiring and uplifting channel.
Nostalgia Nerd
LGR
Action Retro
Lumping these together for obvious reasons. Nostalgia stuff. Nostalgia Nerd is more about nostalgia in general. Stories, hardware, software, magazines.
LGR is more about the gaming side but also features a ton about hardware and software. But also has fun stuff like old cassette players and such. His "going to goodwill for a rummage" videos are fun.
Action Retro is mostly about hardware. To be honest, I haven't watched him too much, its a recent discovery for me. But the ones I've seen are very good.
Anttimation
Finnish history, animated beautifully.
Technology Connections
This guy is a wizard or some sort of magician. There's no other explanation for how he can make the topic "dishwasher washing liquid/powder" a fascinating subject. If you think you'll quickly watch the first minutes of a video to see if it interests you, be prepared to clean the next hour or so of your schedule because you will be watching the whole thing. Even the one(s!) about dishwashers.
Self Sufficient Me
Do you have a garden? Watch this guy. Do you not have a garden? Watch anyway. Australian enthusiasm, great tips, excellent real life experiments.
Tom Scott
If you didn't already know this dude, first of all, where have you been? Secondly, how dare you?
Tom started with those short 3-10 minutes "interesting thing/place" videos, then took some time off and now is doing a 20-30 minute video about every county in Englandland (or was it the UK? I don't know). Must watch.
Right, now to the history stuff:
Miniminuteman
Mr. Miniminuteman, Milo Rossi is a archeologist and a environmental scientist. Most of his videos are America centric, focusing on archeological stuff, instead of recorded history. Thats his more recent stuff. He started on TikTok debunking influencers spouting bullshit, fake archeology and the like. Most of his early videos are about that. Thats where he got his nickname "Googledebunker." He still does debunkings, but its more in the format of "I get drunk while watching Ancient Aliens" type stuff. Or finding old maps and old school books and having a laugh or being horrified about what was taught to kids in the 1800s. Sometimes a bit ranty, often quite fast paced.
Stefan Milo
The other Milo, Stefan Milo. Focuses on anthropology, archeology and evolution. Often has interviews with the people doing the studies. I like his "I wonder what our ancestors thought about all this" kind of thinking. Very relatable. More relaxed and chill than the other Milo. Luckily they have done a video together!
The Great War
World War Two
These channels go through the world wars, week by week. Usually 10-20 minute per episode, though some are shorter and some longer, because some weeks not much happened and some weeks a whole lot of stuff happened. If you want to have a deep understanding of what happened during those conflicts, this is the way to go. Not only do they do the week by week, they have special episodes on specific countries, economies, personages, weapons systems, innovations... then theres the "war against humanity" series on the World War Two channel, that one is quite heavy, as you probably can guess. But IMO its something everyone should know and be aware of. Spartacus, the host of the crime against humanity, suffered way too much to bring this amazing form of infotainment for us. He deserves to have them watched by everyone.
History Time
Long form videos about a lot of different topics, from Samurai to Rome, ancient Wales, lost cities in Amazon. Very relaxed and slow paced, if you like to listen to stuff to fall asleep to, this is the way to go.
Historia Civilis
This is more about politics, diplomacy etc, but mixed with military and general history. "Squares go to battle." His series about the Congress of Vienna is excellent.
Historigraph
Mostly individual battles with a heavy focus on naval battles. Gives excellent breakdowns on how giant battleships hurled artillery shells the weight of a small Volkswagen at each others, at distances of over 15 kilometers. And did so accurately. Somehow.
LazerPig
A drunk Scottish gay pig shouts at things. Its hilarious. But also serious at times. I highly recommend watching the "shut up about cultural Marxism" video. To say its eye opening is a understatement.
Okay I'm gonna limit myself to not add any more stuff. You guys already have a decade of stuff to watch with these alone. Sorry.
