Neon is quite expensive; about 50EUR for 12 liters. It is a pressurized
bottle at 12bar, so it almost looks like a can of hair spray ;-)
The pressure regulator is quite espensive, though, 130EUR. But the good
thing is you only need to buy that once.

Ah i see, so thats why i havent found anything on your site. The good
thing, i guess, is that you already have the neon somewhat sorted out.
How much did the neon cost you?

Hi,
oh, I started reading myself into the topic in November, but I had
several difficulties on the way. I am currently writing down my
experiences so far, I will create a new section for that on my
website, but it will take another two weeks or so.
I have not managed to create a glow lampe or something yet, but I
am confident that I will be able to do so in the next month. I
work with soda lime glass and a primitive soldering torch that you
cal buy in any hardware store, and I even managed to create simple
pinch seals that are vacuum tight. I have some Neon here in a
pressure bottle, but I have some vacuum problems in my setup. The
pump is a two-stage rotary pump that goes down to 5E-3 mbar, but I
still need a needle valve to insert the Neon gas into the tube and
a proper tube connection.
If you count the "buts" in my sentences you can see that there is
a lot of stuff to figure out :-)
It is very exciting, but also quite time consuming. At the moment
I am building a better power supply with a little more juice; 300V
and 10mA are a little wimpy.

And how are you doing with your homemade nixies? I didnt know you
also tried to make some util i read your comment on that video.

Nice pictures! I have a video somewhere around here with a
broken CD47
in a vacuum bell filled with 2%Ar98%Ne, the pressures are in
the same
range (but only down to 3 Torr or so).
