Clickspring is a great maker channel that feels like 20-40 minute long episodes of how it's made (kinda)

He has playlists of his projects and he's been making a period correct reproduction of the antikythra mechanism using the same bronze age tools of the ancient makers who created the original.

EEVBlog is fun if you know electronics and want to learn more. He does a phenomenal series on parts and pieces. He's a layman's wikipedia on "what's an FPGA and why should I know?" As opposed to the more electrical engineering centric sources out there where you already need to know a lot to understand it. He's entertaining and high energy (honestly he strikes me as someone with self managed bipolar or something. That's the vibe I get since I've been friends with at least 4 others who present similar to Dave)

Tasting history, 18th century cooking, and table of the gods are both great historical cooking channels. Some of them will give the recipes for free for you to try at home.

Huygen's optics is a channel run by a understated genius. He explains how optics and optical manufacturing works and he runs his own precision optics workshop in his basement. He once made a spirit bubble level for his pool table with an internal radius of like I'm (meaning it's like carving a 15cm diameter circle out of a 16m wide sphere) so his level had like sub-arcsecond resolution iirc? A human hair underneath it would throw it off scale.

Applied Science is another amazing Science & engineering channel. He made his own back scatter computed tomography machine with a lazy Suzan, an X-ray tube, an Arduino, and a X-ray phosphorescence developer box/camera.
