Cathode Ray Tube (CRT) televisions may be more than on their way to chill with the dodo bird in the land of extinction, but that doesn’t mean the DIY sect amongst us can’t enjoy its reto goodness anyway.
Take this latest MAKE project, for example. Using a wine bottle and a few other necessary components, one could have a glowing CRT reacting on-demand.
Just don’t go for more than 40 seconds or so, warns Instructables member and project creator Xellers. Why? Damned if I know. When things start glowing my mind stops working. Doctor said something about moth DNA. [Instructables]

X-Rays would be a concern especially when working with a vacuum.

Monday, August 22, 2011 at 11:20 PMBecause a vacuum CRT is essentially how you generate low energy (easily absorbed) X-rays. Modern equipment is more refined but this kind of basic set up is what was being used when the effect of x-rays was first recognised by Roentgen.
They would be generated radially as well.
And before you ask yes TV sets could generate low energy x-rays but the glass at the front was thick enough to stop them from getting to where most people viewed TV.

Merely an emitter.
