Each new episode of this I've said to myself "wow, that problem is much harder than I expected". Then he solves it in an elegant way, and I realize the problem is even harder than that!

I'm into a number of the hobbies he's good at, and it's incredible how much skill he has at design AND fine working AND manual machining AND cad/cam AND on and on... I'm really glad he started a youtube channel.
