CodysLab - He does a lot of DIY stuff, like beekeeping, playing around with an old mine, and a large scale hydroponics system. I found him through his series where he tried building his own furnace.
YouSuckAtCooking - a vv funny cooking channel. I don't quite know how to describe it, but all of its content is insanely creative.
Clickspring - insanely well edited videos about manually creating clockwork related items in his home machine shop. The first series he did was on a clock, now he's working on recreating the Antikythera Mechanism as accurately as he can.
bigclive - The Ashens of Technology. Does lots of teardowns and investigates how all of the crap (and some not-crap) that lands in his hands works. Lots of schematics get drawn.
