Building a tracked scooter

A fellow named Bob builds a tracked personal vehicle. He calls it sort of a Segway, but it looks like sort of a scooter to me hence my post title. He doesn't show his design drawings, but he does cover his manufacturing methods and the steps he takes. Not everything works the way he envisioned, and so he does a lot of minor changes to get it all to work. The four videos cover the entire process of building, and then riding, the thing.

 

Turning scrap metal into rebar

This is a video of a Korean Daehan Steel plant where scrap metal is salvaged and turned into rebar. They also, oddly enough, grow vegetables at it. The photography is excellent; several shots are quite spectacular. The video is not narrated, but you'll want to turn the captions on. They are informative and amusingly flippant at the same time.    

 

Manufacturing tea strainers

Once again, we visit a small factory on the sub-continent, this time one in Pakistan. As I've said before, I like these videos because, while Western industrial videos annoy you with a soundtrack of elevator music and chipper marketing blather, these just show the factories and their processes with no comments. 

These strainers are used when using loose tea to make the drink. I couldn't find the M Naseem brand on-line, so I have no idea what they cost, but I'm guessing not much. I did find the site Magic Hour that sells some rather expensive tea strainers. I guess they're needed if you are having a fancy tea party.

 

Never leave the planet without one

 

"[T]he Russian engineers had taped, strapped and sealed our docking module's hatch just a little too enthusiastically, with multiple layers. So we did the true space-age thing: we broke into Mir using a Swiss Army knife. Never leave the planet without one."

The design and manufacture of beer cans

A detailed look at the making of aluminum cans for drinks. The logic of the design choices are explained well, and the manufacturing process is clearly illustrated. An interesting look at a mundane topic.
