have a complete assembly.
I will experiment with different types of gases at different pressures.
Here are some pictures
These are pure air globes powered by my Tesla coil. Below is
of the final system, the primary gas is Argon, although it is
contaminated (note the dimness of the streamers, and fuzziness, this is
from air, I developed a system of charging that gets all the air out,
but it uses a lot of argon).
Here (unless I save up enough for neon, krypton, and xenon
gas) is how I am going to leave my system, it is as
pure argon as I can get, notice how much brighterand more intense it is
my final working system, both free and painlessly grounded to
my finger. However, if ones finger is wet, you are in bare feet,
and standing on a wet concrete floor, it will zap you
in the soft area between the joints of your
fingers, but you can't
expect it to be
perfect can you? I seriousness though, if you touch it, make sure
you are not grounded to any metal, and keep any metal from touching the
globe, this makes the arcs hot and painful, and note also, a higher
pressure carries more current than a lower pressure, so some of the
cooler looking discharges with more light are less safe to touch.
above, changing the
pressure can drasticly change the characteristics of a globe, below are
pictures of how my globe looked during an experiment (I don't intend to
keep it this way,
because it hurts to touch it) of an almost atmospheric pressure
discharge, a very interesting fact, is that a covered discharge
terminal actually raises the working pressure of a plasma
display! One would be led to believe that no cover would mean
less resistance and more power, but this is not true. I now
believe that the thin insulating layer acts like a capacitor,
increasing transient current, so a higher pressure discharge is
Note in the pictures below, the non grounded arcs that do not touch the
glass are actually very orange in color, but the grounded (slightly
tingly) arcs are very white, almost blueish! I have a video at
the bottom of the page. The interesting colors and raised
pressure came from acedic acid and CO2 leaking in from my silicone, I
have never replicated the results seen here.
