A boom mic and a terrible robot.

• Toolbox Tours is a channel that tours the workshops and toolboxes of mechanics and engineers. Thanks to Mat for sending over their most recent video, which is something different: a fascinating forty-minute deep-dive into a surgeon's toolbox, showing the details of all the medical equipment that might be needed to fix a human body. (While there's no actual surgery images in here, and no real blood or body parts, this might not be for you if you get queasy at medical stuff and have a good imagination!)
   
• And thanks to the multiple people who sent over Dallas Taylor's new channel: he's touring big American TV productions and getting behind-the-scenes interviews with their sound mixing teams. Which sounds a bit dry as a description, but Dallas' technique is: let the experts talk, edit it down perfectly, and to include lots of little other behind-the-scenes details. And the result is really engaging! Only two videos as I write this: Inside the sound of Jeopardy and Behind the Boom Mic at SNL. They're both worth your time, and I hope there's more to come.
   
• And thanks to Allan for sending over Chris Staecker's video on The Rise and Fall of Chisanbop. It's a feature-length video essay about a mostly-forgotten finger-counting technique... and it does, I think, really does need to be feature-length! There's a huge amount of research that's put all this together, including interviews and tracking down physical stuff on eBay, and it's put together in a really engaging style. I didn't have to skip forward or try to summarise: it was just interesting.
   

• Three teens almost got away with murder, then police found their Google searches. A bleak story that raises questions about digital rights and privacy. (Strong language.)
   
• Rig 1938 is the world's tallest waterslide tower and it took me several minutes of searching to confirm that, yes, that photo is real.
   
• Riding with Strangers: photos of California hitchhikers in the 1970s.

And finally: my Tesla robot hates me. (Strong language.)

All the best,
