alt Hacker NewsWe still get cathode ray oscilloscopes. Apparently the og has a grid screen. Wonder what it costs to get a CRT maker to get custom dimensions, phosphor colors, curvature etc?

Alternatively, apparently you can make a true vector display by steering a laser.
Here's a DIY example: https://www.youtube.com/watch?v=bdo3djJrw9o
I suppose you could even point that at a screen with phosphors on it for a more CRT-like effect. (Maybe you'd need a different kind of phosphor since you'd be exciting it with visible light rather than with an electron beam, though.)

Do we? I was under the impression that CRTs were not being manufactured anywhere anymore. I could definitely be wrong, but I couldn't find anything with a quick search.
AliExpress has these 4-inch "flat CRTs" that look like they scan the vertical axis onto a sort of parabolic screen. I've thought about playing with one, but decided I don't want to risk shocking myself for a tiny distorted image. Still have no idea for which application they're intended.
