Here are 5 YT channels covering technology, engineering and tools that feel much less monetization-focused, but still produce very informative content:
- Tech Ingredients
- DIY Perks
- Brainiac75
- Project Farm (not really about farming -- cut & dry tools & such review)
- AvE (Arduino vs. evil) (not really about arduino)
(sibling comment included a couple others that I would have included here also)
The first two focus on engineering and building unique things, so are probably the most similar to the creators in question. AvE is all over the map and an either love or hate kind of channel -- and the channel seems more about educating, teaching and evaluating others' engineering.
No talking, no music, goofy thumbnail pics with emoji faces or red circles. Just creating.
The content may not be your cup of tea but personally I as well as others seem to enjoy them.
