I've been enjoying bigclivedotcom recently. He mostly does tear downs of cheap Chinese (ebay) electronics which I find interesting (and educational). He also has the odd video on making booze and vaping (from a technical aspect).
I've also enjoyed SV Seeker. It follows a guy building his own 65' steel sailboat. I'm not entirely sure he knows what he's doing but the process is interesting to watch (and he shows his screw-ups which is probably more informative than the successful jobs).
