Believe there's one in the garage

Post #324,016 by Ashton 4/4/10 4:59:13 PM Reply	Believe there's one in the garage culled from some flea market. Needed some repair to a jack, as I recall. Works (well, worked.. haven't looked lately) Yeah the crook-neck squash tube is a fine HS intro to bending electron beam. Yours if you want it (better than nostalgia, I say! It's B&W; doubt you could register color pixels in that manner, sans a lot of fine-tweak circuitry and a very stable PS.) Somewhere too is a 1.5" Panasonic; a marvel of CRT/electronic miniaturization at the time. Used to use it with a a wireless video xmitter.. (from in-house set) to tune my string-operated antenna 'rotator'. Because I could. Now we expect the barely-conceivable ... as routine. I believe the word is jaded. (I wonder if any of the various stages of 'TV-glasses' have yet reached the pinnacle: the full-illusion that you are watching a 60" wall-set, with full resolution. One would have to audition such, live -- the previous ads all lied.)

Those Sony engineers were very clever. People probably aren't going to be generating electron beams in handheld display devices ever again... Cheers, Scott.

Bending the end of the CRT was an interesting solution, and had the advantage that the image emitted from the same side the electrons struck, producing a much brighter picture (and they could add a heatsink to the back). But it made the physics of electron beam deflection very complicated. They decided that it was not possible to do three-beam colour that way. I wonder if anyone tried it with Sony's Trinitron technology. Like a lot of mass-produced technology developed and consumerised in the middle of last century, cathode ray tubes are a bit "how they heck did they get that to work?!", really. Wade.
