Bunnie Huang goes shopping in Shenzhen.
He makes some very good points about how the end of Moore’s law has come for processor speed. The end of shrinking the gate size is coming shortly as well. Not necessarily because the physics don’t work but because the machines to make the transistors will have gotten prohibitively expensive. It seems that there was another exponential in Moore’s law.
With all the teething problems the F35 is having and the extra costs involved it would pay to maintain the line even at a skeleton level. The problem is that that the way these things work out, once a line shuts down, it’s scrapped and gone, tooling, fixtures and all. Which has always struck me as a stupid way to do things, but the military doesn’t seem to want to make sure that reserve funding is kept to keep lines in storage even for operational aircraft once production stops.
A wonderful gallery of photographs of the American textile industry.
It’s easy to see that, regardless of the obviously proud and dedicated people working in those factories that the industry is slowly dying. Like so many it’s being strangled by a leadership class taxing everything that moves for money to spend on their own offices and privileges and hand out to the favored people.

An interesting history of the early days of injection molding.
Yet another of those excellent Japanese industrial films.
Nikon 80th anniversary video.
While the inspection techniques have improved, the basic grinding techniques for grinding lenses hasn’t changed very much.
The Engineer guy does great videos on just about everything. Injection molding is used for just about every plastic process one way or another.
A great series of videos on workholding from Misumi. I will update as they become available. This is an important thing to know about when you are designing. How a part is made and how much it costs can be different depending on how it’s held for manufacture or assembly.
Here’s a BIG weldment being delivered for a deep ocean ROV for mining.
