For my part:
https://www.youtube.com/c/BreakingTaps
Breaking Taps - 21k subs - Originally found via share from Ben Krasnow, definitely worth it. Tinkerer/fabricobbler that celebrates the learning.
And these are ones I've been watching for a while but still have relatively low sub count.
https://www.youtube.com/c/MarcoReps
Marco Reps - 146k subs (ok, lowish) - Another tinkerer, although mostly in high-precision lab equipment and various builds of interesting projects. Also a very funny dude.
https://www.youtube.com/c/OonaR%C3%A4is%C3%A4nen
Oona Räisänen aka windytan - 2100 subs - She's had a few articles posted here, super creative RF/audio hacker/tinkerer.
https://www.youtube.com/c/EdgePrecision
Edge Precision - 56k subs - One of my favorite machining channels, zero nonsense, tons of practical advice that I'll never use.
https://www.youtube.com/user/NACImageTechnology
NAC Image Technology - 650 subs - Commercial account of high speed cameras, just eye candy.
https://www.youtube.com/user/corningmuseumofglass
Corning Museum of Glass - 150k subs - Fairly prolific publisher of guest artists creating pretty amazing glassware.
https://www.youtube.com/c/eastcoastish
Eastcoastish - 3.8k subs - Impeccably documented mods and builds of a variety of small displacement motorcycles (Honda Monkey, CT70, etc)
David Bennett Piano (356K). Music theory (or selected phenomena ofi t at lesat) with examples. https://www.youtube.com/channel/UCz2iUx-Imr6HgDC3zAFpjOw
DarkAero, Inc (29.7K): Three brothers inventing an airplane. Carbon fiber, planned to sell as a kit so it all has to become production ready. https://www.youtube.com/channel/UCPUZCBNrduwUsw_MTW-sDxw
saVRee (74.4K). More engineering explained in detail. Sadly very very slow, speed up the vids :). https://www.youtube.com/channel/UCosExgfjj-DhMJXnQd2Y4gA

Cheating a bit (know them for longer, but they have to be underhyped despite their size):
Subject Zero Science (193K): super well produced bleeding edge science explained. https://www.youtube.com/channel/UCRXRbi80k0_vcIfgpOSerTg
The Thought Emporium (746K): Bio hacking and DNA editing. https://www.youtube.com/channel/UCV5vCi3jPJdURZwAOO_FNfQ
https://youtube.com/channel/UCBDp7ydYTHi1dh4Gnf3VTPA
I believe these also correspond with an actual course, although I can't find a link.
Eventually I'll probably share the whole kit & kaboodle with Hacker News. Have to make a proper writeup though (because people are impatient and won't sit through dozens of videos to get the whole story from the beginning haha)

They take the time to make quality videos (even if it takes week or even months) as opposed to others that rapid fire publish videos.
Some channels I'd previously recommend had quality drop. Rather than investing in a topic they got a spammy feel to them.
This German gentleman rescues broken stuff from the scrap yard and repairs it. On this video [0] he upgrades a basic welder to increase the duty cycle. I specifically like the way he describes his upgrades using diagrams and basic explanations. Link to his channel at [1].

Xyla Foxlin: creative, very enthusiastic crafter, canoe building was fabulous (67k): https://www.youtube.com/c/xylafoxlin
The Tim Traveller: quirkly little places, fabulous humour (190k): https://www.youtube.com/c/TheTimTraveller
There's a LOT of "play with X, do activity Y, do this cool thing Z" videos that my kiddo loves to watch while also playing, but could be taken to the next level EASILY.
The fact that PBS and mainstream kids networks don't do things like this, or a more professional production network, is strange to me.
Likely professional production is poison pilled by preassumptions of previous programming paradigms, or the sponsorship fundamentally ruins it.

Another neat (and currently obscure) one is CodeSync; the subject is Elixir and the Erlang BEAM.

I myself sometimes participate their weekly open mic sessions.
