Sampson Boat Co. - British man and friends rebuild wooden sailing boat. If you have any interest in boats or craftsmanship you'll enjoy. Watch from the very beginning to see their incredible progress.
Beau Miles - Charming and slightly rough Australian man has strange adventures and philosophizes along the way. He gets excited about particularly useful/edible bits of trash along the highway.
Primitive Technology - Silent man with blue shorts exists alone in the jungle and has been working his way up to iron tools. He is freakishly fast at making fire with only two sticks. Watch in order to see his progression and turn on captions to see his commentary.
Spirit Of The Law - Extremely thorough Age of Empires II science and analysis. If you thought this 24 year old video game was dead, think again.
Settled - Old School RuneScape player plays the game with extra restrictions that create surprisingly compelling storytelling. "Swampletics", his Morytania-locked Ultimate Iron Man is legendary.
DIY Perks - British guy makes mostly brass/wooden PCs and other tech. His creations aren't always the most practical but they are always interesting. His slim PlayStation 5 was neat.
There's a handful of sustainable farming channels that I like: No-Till Growers, Richard Perkins, and Josh Sattin Farming. If your interests include food or growing stuff then these are for you.
