I love Cathode Ray Dude and found him through TC. I absolutely love that kind of fact-based educational video that's just deep diving a single specific facet of technology.

Seconded. Incredible videos. True unfiltered art.

Bobby Duke's good too. Fairly talented, but also just a dad making sculptures while fuckin with cinematography.

This Old Tony (amazingly creative machining and engineering videos), look mum no computer, big Clive (quite technical electronics tho), hand tool rescue, and diresta are all good work/texhnical/engineering/craft based channels. Aging Wheels has evolved to much EV content, and has worked with technology connections. Our Own Devices has some interesting content too, but I’ve only seen a few of his videos.
