Here are my favorite maker channels:
Frank Howarth - probably the best woodworking videos I have seen, from a production quality standpoint. Doesn’t shill for any particular toolmaker, as far as I know. Built his own 4x12 foot CNC router!
Keith Rucker - Keith makes great metal machining videos.
Tested - Adam Savage et al. Recent fluff pieces for Honda aside, their stuff is usually enjoyable.
I Like To Make Stuff - Great, concise build videos from a small home shop. I believe he has a Glowforge on order.
AvE - Hilariously irreverent tool teardowns and the occasional instructive video.
Jimmy DiResta - Makes some awesome rustic stuff, often out of found materials. And if you ever want to cringe about shop safety, he’s your guy! Has done a couple of sponsored videos but makes it clear up front, I think the most recent was for Lincoln Electric.
The Samurai Carpenter - Some beautiful woodworking, mostly with mortise and tenon joinery. Uses a lot of Makita tools but is not sponsored by them.
Clickspring - This guy does mind-blowing things with his tiny metal lathe.
April Wilkerson - Great look at a beginner learning to use a wood shop. Fair warning, shills for Triton and occasionally other brands, but she says so up front most of the time.
This Old Tony - home machinist with a great sense of humor.
SV Seeker - This guy is building a 74-foot steel boat. In his front yard. In Tulsa, OK.
Laura Kampf - Makes some great stuff. More soundtrack and less discussion / explanation than I usually like, but she shows the process very well.
Brian Oltrogge - Makes great stuff, mostly casting with his homemade forge.
Applied Science: Ben Krasnow, a fascinating renaissance man who makes amazing things (like building a scanning electron microscope, from scratch, in his garage.)
Death Wears Bunny Slippers - In 2011, this guy and his family bought an abandoned nuclear missile silo. He’s just started posting videos about the process of opening it up (it had been buried), cleaning it up, and turning it into a home.
Simone Giertz - The Queen of Shitty Robots. She’s now part of the Tested team, but is still making robots and other stuff.
And my favorite non-maker channels:
Cody’s Lab - College student in Utah who does a lot of chemistry experiments, and a lot of metal refining, some from an old family gold mine he’s opened up.
Tom Scott - Great videos from a world-traveling Brit.
The 8-bit guy: Lots of discussion and explanation about old computers and how they worked.
Matt Parker - Mathemetician / Stand-up comic.
CGP Gray: Needs no introduction.
The Engineer Guy - Engineering professor explains the reason behind the way things are built.
Postmodern Jukebox - Today’s hits, yesterday’s style.
And Brady Haran’s family of fascinating science channels:
Periodic Videos - Lots of cool chemistry experiments.
Objectivity - digging through the archives and objects of the Royal Society
Deep Sky Videos - Astronomy stuff
Numberphile: Math videos for the non-mathematician
Sixty Symbols - Physics stuff.
Computerphile: Computer Science
