A few I like:

https://www.youtube.com/@Blondihacks - A (primarily) model engineering channel with a focus on hobby / home precision machining

https://www.youtube.com/@daliborfarny - A guy working to keep the art of nixie tube manufacturing alive

https://www.youtube.com/@StuffMadeHere - Silly / improbable projects mostly for fun (e.g. basketball hoop that you can't miss a shot)
