Dear Dalibor,
good job!
I just started preparing glass wafers with pumping pipe:

Yesterday I found devices for nixies (photolitography process for polish
LC513 tubes). Unfortunatelly I have only "5" and "7" and "grid" templates.
I wonder about photosensitive emulssion. Any suggestions?
Hello,
Thanks, I scanned numbers from z566m, so 30mm. I plan to start on
40mm numbers, and then go higher :-)
Have You received my email in czech yesterday?

Oh wow! Now thats some promissing progress. Cant wait to see some
of your tubes! By the way, how big are those etched numbers?

Hello!
Nice, I am glad You are really working on it, so do I :-) I
am spending all my free time making nixies, not much time to
write about it on blog.. I am now in phase of building glass
lathe again, the previous one was of bad design..
I made several stems from Simax (boro) glass using a
lead-in-wires with tungsten middle sealing part. I tested
them on helium leak detector and some of them are ok! :-) So
now I need the lathe to make the envelopes and seal it..

I also did simple experiment with photo-etching of numbers
from thin stainless steel sheet. It works, but the etching
proces will have to be made more even and much much faster to
prevent under-etching..

I also had to build new transformer spot welder, the
capacitor discharge welder waswaste of time :-( the new one
can be adjusted, tungsten-steel welds are now really easy :-)

Thanks Michel, I am planning to do all kinds of glow
lamps before I get a real torch, a real colon display
would be nice.
Next, I will experiment with the aluminum oxide
insulator. Sadly, it is quite brittle, so if you shake
the tube too hard it will break loose. But I could use
this insulator to prevent parts of wires to glow.
But I doubt that air is going to get any brighter, Argon
would probably yield much better results.

Nice work Jens!
Would be a good combination, nixie tube clock with
glow lamp colons or
something like that. It doesn't seem as bright as
neon but that is
probably because it is a prototype.

Hi folks,
finally I got my first glow lamp working. It is
the third try, therefore
I call it "GL-LS-3", short for glow lamp lab
sample 3. See two pictures
here:
http://www.jb-electronics.de/tmp/gl-ls-3_1.jpghttp://www.jb-electronics.de/tmp/gl-ls-3_2.jpg
It consists of 9mm soda lime tubing and Dumet
wire. The gas filling is
normal air at 9mbar. It ignites nicely at roughly
550V DC.
I used a simple propane torch for the glass work.
Will switch to a
hand-held oxygen-propane torch in a few months
though (when I have
enough time and money).
I will get my needle valve in two weeks or so,
then I will be able to do
something with neon. Believe it or not: over two
months lead time for a
silly needle valve... Anyway, I hope I will have
the tube making content
prepared for my website by then. It is piling up,
but there is still
much to do.
Best regards
Jens
