If you're not comfortable with something don't do it. That advice is for 
everyone. I was lucky to have a very talented, experienced and safety conscious 
instructor who took every precaution. The processing bench was set up in such a 
way as to keep body parts as far away as possible. No nails or screws anywhere. 
The mains switch was well away from the bench.

> come out of phosphor-coated tubes being heated.

The real danger is broken tubing (this includes fluorescent lighting). 
Fabrication can be done safely. We worked in a large, well ventilated area and 
he amount of mercury required is very small, a tiny drop. The transfer from the 
bottle to the special tabulation was done as rapidly as possible, immediately 
spliced and tipped over into the finished tubing.

As for some of the toxic phosphors, let's just say that you should keep an open 
cut well away from them. We threw broken lead glass in one barrel, everything 
phosphor coated in another. I can't remember how the latter was recycled but it 
was definitely hazardous waste. As for the lead glass, well, it has lead in it.


> A couple was recently killed (electrocuted) while making woodburning art with

Unfortunately the body count is higher than that. I don't know the number of 
accidental deaths so far but it's incredibly stupid and irresponsible on the 
part of the people explaining how to do this on YouTube. It may have something 
to do with the fact that they don't appreciate the danger, either. FAIL.

I wonder how many people have gotten zapped by the capacitor while attempting 
to remove the transformer. Then there's holding a wire up to a Tesla coil. Also 
on YouTube. And if you ever build a Jacob's Ladder remember that the rods can 
get quite warm so when you reach out to adjust the angle...well...

Correct, you cannot. You need to drive the Monoscope like a CRT, with a 
raster, then read off the output and drive something else with similar 
raster deflections.


Actual terminals (e.g. Conrac) were built with this chargen, there are 
fleeting references online.

And you survived to tell about it. Bombarding is pretty dangerous, and it's 
the main reason why I decided not to get into neon art, the other being 
toxics such as mercury and who knows what other nasty things come out of 
phosphor-coated tubes being heated.

A couple was recently killed (electrocuted) while making woodburning art 
with a microwave oven transformer.

I'm happy to say I've only been tingled with high voltage once over the 
past 10+ years, and it was very low current (less than 1mA) because of the 
circuit design.
