Congratulations on first light!
Are you considering gettering or gas fill for sealed-off ones?
Thank you very much!
Have a problem, for now at least, to get both of them. When I get them I
will try all options.

That's our own Aleksander Zawada - he does some beautiful work making vacuum
tubes and nixies. I didn't even know he was working on

Hi Daniil,
I don't think it is too important who the tools belong to as long as you
can use them. It is a fascinating opportunity for you to acquire real
glassblowing skills.
I am so busy at the moment with university stuff that I cannot focus too
much on Nixie tube making... Anyway, my next

Nice job, Daniil. I like the looks of those stems. Congratulati
Jens,
No no it's just looks alike, I'm totally novice.. learning everything by
myself. You can ask Dalibor :)

Daniil,
wow, that looks really advanced! Not the kind of cheap tinkering I do
;-) Can't wait to see your first Nixie tubes!

Awesome work Jens! :)

and aquired half a room for my 'shop, only problem is I still dont
have time to use it.

Hi,
here are the pictures of one of the colon tubes (as always, air at 15mbar):

Sadly, the upper dot does not always light up. It was a silly idea to
parallel the two cathodes, next time I will have t
Hi again,
here is a picture of my "lab" / desk. I do not have a separate room for
my tube making, so I have to clean off the desk every time I need to
work for the university. It does not take much time, and so it is
actually an advantage because it forces me to keep my lab tidy.

Hi Dalibor,
it is a Pirani gauge. A friend of mine gave me a two-stage rotary vane
pump with flange terminal and a Pirani gauge that works fine down to
10E-4 mbar. Will take a picture later. I will mount my flange needle
valve when it gets here (a couple of days) and then I will take a lot of
Hello!
By the way, how do You measure the pressure in the system? You mentioned
the glow lamp is filled on 15mBar...
Could You send a photo of the system You use for pumping and filling the
glow lamps?
The capacitor welder You have will work well, it is not suitable for
welding materials w
Hi guys,
thanks for your advice. I think the problem is the one Dalibor pointed
out: with Dumet wire the sputtering is very high. Also, since I am using
no noble gas (except for the less than 1 percent there is in ambient
air), the cathodes are having a much harder time anyway. So for now I

Keep up the good work !
If you need have some DXF files (vector format) on the digits you want, or
a image of the whole set, in a raster format, throw in my direction. I'm in
good with a guy that owns a steel cutting laser. 4000W of CO2 goodness.
He'll run small jobs for me for nothing, as long
Good job Jens!
Molybdenum is not suitable for our purposes, it has low sputtering, but is
very difficult to weld because of the high melting point. If You can get
even lower sputtering with stainless steel electrodes in combination with
mercury filled tube. This is the way how were the latest nixi
First of all, well done ! Good work :)
I know the digits are made of dumet wire, what plans do you have for trying
other materials ?
I have read previously that molybdenum wire, or molybdenum coated elements
in tubes are often used.
Is something like this suitable I wonder ? I see it is being
Nice one Jens! I'd go for the binary clock, why not?
I was thinking, is it possible to use a high voltage SCR in series with a
lower voltage NPN in a construction like this:

The NPN can then turn off the SCR, so you can use a normal DC power supply.

Wouldn't it be possible to use a biasing network with resistors like they
used to do when transistors couldn't handle the 170-180V that a Nixie
needed in the early days? Or perhaps run the Nixies from a
positive/negative powersupply split in half with +/-275V and a biasing
network with resistor
I've wondered about using little to92 triacs to run nixies from,you
can get them up to 800v fairly cheap, you'd need ac to power the tubes
of course.

also, air is not the most ideal gas for discharge tubes, although it

So when are you ready to take orders? ;)
