"All men dream, but not equally. Those who dream by night in the dusty recesses of their minds, wake in the day to find that it was vanity: but the dreamers of the day are dangerous men, for they may act on their dreams with open eyes, to make them possible."

Latest notes

The first CRT display was made in 1899, in a small workshop. Monochrome, of course.

Required technologies: glass casting, wire forming, vacuum-pumps, sheet metal fabrication.

Required materials: glass, copper wire, a fluorescent pigment, a conductive coating, and any alkali salt with thermoionic properties.

If anything "happens" to global trade flows from China's gigafactories, artisanal-built CRTs gonna come back like the 1990s never ended.

People think of Standard Definition TVs when they think of CRTs, but there's actually no necessary connection.

Those beautiful, crisp, sharp, white lines in Asteroids are much older than television - the very first CRTs were vector-based not raster-based, and technically-capable of amazingly fine resolution. Oscilloscopes FTW!

But there were no computers around to make use of their full potential.

Any modern computer with stereo audio output can drive a vector CRT, with resolution hundreds of times sharper than a modern OLED or LCD screen. The limitations are not resolution per se, more around the rate of change your op-amps are capable of, and leakage of storage capacitors.
