Fascinating 1960s film of colour CRT manufacture

So many interesting details....

I always thought CRT construction seemed wildly overcomplicated. I realize everything is necessary but still. It's remarkable that anything so mechanically complex and sensitive could be produced in such high volume at such low cost. Nearly every home in the USA had at least one CRT in it, likely the most complex device any of the family members would ever touch yet cavalierly dismissed as just another appliance.

Thanks for posting this. Would be nice to see something similar for modern flat screen assembly!

Just the sheer number of technical paradigms that were honed or even invented to make this contraption possible. Amazing feat of humanity.

But look what we've let it do to us.

16:37 look at the size of that Helmholtz coils

I remember Rod Humphris (RMIT lecturer and television electronics expert) telling me that the first shadow mask tube template for etching the holes in the shadow mask was made by photographing an array white ceramic food plates in a car park from a helicopter.

Cool story and I want to believe it but it would be almost impossible to get the scale correct with the first shot, which means they'd have to rescale it, and if they had the ability to (re)scale it then they could have just scaled an original that didn't involve a helicopter. Or so it would seem.

Don't blame the technology. Like the Internet, firearms, chainsaws, pharmaceuticals (read: "drugs"), etc. the technology is non-sentient. It's the mind controlling them that does something "right" or "wrong".

As a person who shot the positions of "Topol" strategic missiles from a helicopter, I can say that even some inaccuracies of the actual placement in the pictures look very evenly spaced. But, at the same time, optical systems are quite good for many years, it was possible to draw a mask on a piece of paper in a cell and take a picture of it from a distance of 1500m through an optical sight.
