For me I really do enjoy watching some of the Locking picking lawyers content and he is an expert when it comes to picking locks!
Another few are mental outlaw (although I think everyone knows of him here) and Steven Bridges who makes videos on card counting at casinos and he shows how much he wins/loses from playing
steamhead, a delightful maker (1.6 k subs only) working on steampunk contraptions (eg Victoria, the singing automaton) using all sorts of tools, laser cutter, 3d printer, Arduino, etc. while keeping his videos really tight and easy to watch. I’m not even a fan of steampunk things but since discovering him, I haven’t skipped a single one of his videos.
