There are so many great channels on there! Here are a few of my recent favorites:

Laura Kampf - german maker and problem solver, currently renovating a 120 year old house

Jimmy Diresta - maker and designer, also renovating an old house in upstate New York

Adam Savage - from MythBusters, interesting builds, and interesting discussion of shop and building techniques

Rambling Wild Rosie - former long-distance hiker and interior designer, renovating an old house in the forest Sweden, figuring things out as she goes - very beautiful and peaceful videos

Also loads of great wood working channels: Paul Sellers, Woodworking for Mere Mortals, Izzy Swan, Samurai Carpenter, and on and on!
