Posy seconded. He's weird (and I'm certain he would agree), but in a fun and interesting way. The music used in his videos is composed and recorded by himself, btw.
A recommendation of mine is Bad Obsession Motorsport. Two men in a shed put a Celica engine in an Austin Mini. So far it's taken 12 years and 41 episodes. Some astonishing engineering going there.
If you're into cars, I'll also recommend "driving 4 answers". Very well researched and presented videos about engine technology.
Seconding Bad Obsession. Not only is their build quality outstanding, their video production efforts are top notch. Their dedication to the concept and execution of Project Binky is nothing short of amazing.
