On mobile so no links, but I enjoy the following YouTube channels:

Primitive technology: researching/developing e.g. metalworking, agriculture, building techniques without using any premade tools. No voice but closed caption explanations.

Primitive skills: homesteading in Vietnam with traditional techniques, minimal outside materials/tools. No voice, closed caption explanations.

Wintergatan: years-long project to build a marble machine musical instrument reliable enough for stage performances. Lots of experimentation and some meta engineering techniques too.

Jamie Mantzel (spelling?) Used to be building a giant robot in his garage, more recently built small boats and a house. Haven't checked recently.
