As in, channels where the presenter is laid back, calming, and the content is slower paced and chill. My go two examples are LGR for retro computer stuff, and Hainbach for experimental tape music.
Attoparsec, Chronova Engineering, and polymatt all fit that description.
Most of what I would have suggested has already been posted by others, but I can say Kruggsmash’s Dwarf Fortress stories do this for me. The Waddlesquash/Kingdom of Autumn series he did (with the pumpkin mod) is particularly laid back, but even the action-heavy series are calming to watch/listen to.
“Tally Ho” comes to mind, where a guy turns a famous wreck into a boat.
Paul Harrell (RIP) for guns. His presentation style was a masterclass on how to convey information in a unbiased manner. Anyone who teaches anything to anyone should take notes.
He was entertaining without trying to be entertaining. If that makes sense? The man was demonstrating and testing hypotheses without giving two shits about likes and subscribes. Loved his dry humor, sometimes caught me off guard. “Wait! Did he really just say that?!”

He does great work!
Bill Hammack - TheEngineeringGuy
All manner of engineering gadgets and phenomena explained clearly and calmly.

bigclivedotcom - I have no idea what he’s talking about 90% of the time but he’s generally a relaxing watch.
Ali Spagnola and Aging Wheels aren’t quite what you’re describing in terms of being calm and chill but I still love their stuff.
Seconding others’ recommendations for Technology Connections, TheCrafsMan, Cathode Ray Dude, and Techmoan.
Just background noise - morrowind challenges
Atomic shrimp - Walks, cooking, gardening, pretty varied content
In deep geek - In-depth fantasy lore
Patrician TV - ultra long format video essays on Elder scrolls games (also other games related stuff but his Elder scrolls essays are his best work imo)
Another for In Deep Geek. All the ones I’ve seen listed here I’ve seen before I swear people in the their video comments often mention their soothing voice deliveries.
+1 for atomic shrimp, was going to comment about him. He’s so positive and calming, I didn’t have much of an interest in the stuff he does until I started watching him, but his quite calm demeanor and positive energy makes it so easy to watch!
Click spring for watchmaking. It can take 6 months to do a single build and they’re insanely intricate.
Cathode Ray Dude
Michael MJD: Retro tech youtuber with a very calming voice and video style. Often installs operating systems on unusual devices.
Techmoan: Tech youtuber focused on old audio equipment.
Ashens: British Youtuber, who has been reviewing mostly poundshop tat and occasionally other random items in front of a brown sofa since 2006.
Geowizard: British Youtuber who does online Geography quizzes like Geoguessr and sometimes goes on adventures. The former part is probably more relevant to your question, though even his adventures have a nice, calm narration and music (that he wrote himself).
The Trek Planner: Finds interesting spots on Google Earth and hikes there, usually in the deserts of the Western US. Videos are usually more focused on the journey than the destination, so there will always be lots of nice views of nature. Honorable mention also to Desert Drifter, who did similar videos but unfortunately passed away recently.
Second Geowizard. Chill British dude.
His Geo Detective bits are exactly what OP is looking for. No competition, just using his knowledge, skills, and luck to help people find things, usually from historical pictures of their loved ones.

City Planner Plays is quite literally the Bob Ross of city building games. He uses his actual professional knowledge of city planning to build really creative and compelling stuff, and he makes it seem easy enough that you want to try doing it yourself. He has commissioned a library of chill lofi beats that he plays in the background of all his videos, which adds to the vibe immensely. And on top of that, he seems like a sincerely pleasant guy, just having fun doing a thing he enjoys doing. It’s an absolute gem of a channel.
Food Wishes with Chef John. Very fun, laid back, and dare I even say informative if you’re into cooking.
I revisit his channel every year at Thanksgiving when I need to prepare a turkey. His super simple roasted turkey video has served me well the last 5 or 6 years.
I always feel so reassured when you get to that one tricky step and Chef John says “But if you didn’t, that’s ok! It’s still gonna taste really, really good!”
Ogmios - dude drives carefully around London, is nice to pedestrians and other traffic, and has a calming voice.
