Homemade nixie video!

[kay486]

Just check this out! I knew he would try make one someday. Its really nice video, even when the tube isnt working at the end.

Nice video - ...waiting for second part :)

It's my old experiment, but I think that it would be helpful:

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).

Nice Alek,

thanks for sharing.. Are You still working on nixie?

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.

[jb-electronics]

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.

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?

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.

Yea, i know ist expensive so i wanted to know how much you eventually payed for it.

[Dalibor Farný]

About the neon, I am in touch with a salesman from Messer group, he offered me probably the same bottle - Cangas 1l 12 bar bottle, 12 litres of neon, 50 eur + VAT. They offer pressure regulator what can be evacuated for 200eur... and simple one for 100 eur.. Are you sure You will be able to use this cheaper one? I am afraid of leaking or air contamination.. :-(

You should be able to do better than that if you don't need that much neon.

http://www.montroy.com/catalog/main/itemdetail.app?item_no=NEON

It's 0.9 liter of neon at atmospheric pressure for about US$20. This way, you can get away without a pressure regulator or
needle valve. Fuse the flask onto a bit of tubing on your manifold with two stopcocks near each other*. Once you're pumped
down, spin the one closer to the flask a half turn (which will quickly open and close it again). This will trap a little bit of
neon between the two stopcocks, at a pressure somewhat below atmosphere (this will drop as the neon is used). Then
meter the neon into the manifold with the second stopcock. Since you're partitioning out maybe half a milliliter of neon at
atmospheric pressure or less into a manifold that's considerably larger, even if you just leave the second stopcock open,
you'll already be down to something in the useful range. If you want more pressure, close the second stopcock and spin
the first again.

This is not a precision setup by any means, but for those of you who'd like to play with neon on the cheap, it's a reasonable
way to get going without spending too much money.

* These glass flasks have a thin glass seal to keep the neon in. The usual way to open one is to put a clean piece of
ferrous metal in the tubing before sealing it up. Then open both stopcocks and run your vacuum pump until the manifold
is pumped down good. Then close the stopcocks and use a magnet to yank your metal chunk over to break the glass seal.
If your metal chunk isn't clean, your neon will be contaminated.

[Dalibor Farný]

Nice solution, but I am afraid I would destroy the flask and let the neon go out ;-) If I were from US I would try it, but because I am from EU where we have nothing like this or if we have, it is several times the price in US, I will use a cangas bottle :-(

The solution with magnet is very nice!

Technically, you don't need a pressure regulator for the 12 bar bottles - they're only required for the 50 bar and up tanks. You
can operate one of the 12 bar bottles with a simple needle valve that serves for both connecting and opening the bottle as well
as to meter gas from it.

true, but if you mess up at 12 bar everything is gone, if you mess up at
1.2 bar then no harm is done. I try to do small steps at the moment :-)

He made a nex video. And now the tubes are actually glowing!

Quite amazing! I am confused it seems to work this well with epoxy.
Let's see. I actually created a Youtube account just because of this guy ;-)

And the best thing is that there is your name in the tube! :D JB, i guess you are first of us who always wanted to have a custom made tube. Even though it is just a coincidence.

Yes I still working on nixie and another tubes. For example I'm working
about photocells and tubes similiar to 3NF. Yesterday I tryied to do
tube with 3 triodes, 6 resistors and 4 capacitors. Unfortunatelly it
broken because of stupidity. I did mistake during burning getters. I
will have to try again. Lucky, I prepared a good tube with 1 triode, 2
resistors and 1 capacitor. That's why I know that will be good:).

My aparature for filling nixies is rather primitive. I have my own glass
diffusion pump (1 stage), rotary pump, my own glass Penning manometer,
glass valves and glass bottle with neon. I have a lot of glass bottles
and two metal bottles with Penning mixture. Poland is very strange
country. I rescued it from trash!

Awesome work. Reminds me of these monsters.

[Dieter Waechter]

Friends,
Ron's work is by far the best self made Nixie tube work I have seen so far.
It is unbelieveable he worked that all out in such a short time.
I love his videos and especially the detailled explainations.
Although I will not start making Nixie tubes, I find that topic extremely
interesting, and I can't wait to see more artworks from Ron.
Yes, I call it "artwork" since I know how much knowledge, talent, flair and
intuition are necessary to do that all.
The thing with the old toaster! ;-))) Isn't it great?
And can you see how much fun he has when building it...?
He is laughing loud somtimes ;-)
A BIIIIIIIIIIIIIIIIIIG THANK YOU to Ron for making that tube and the video
and the explainations!
(I wrote him seperately, too)
By the way: Note that I have not "ordered" the tube from Ron. I was
surprised as you when I saw that video and I still can not believe it. ;-)
I hope the tube remains glowing and I can design a nice case, electronic and
software for it.

You did not order it? And i though you commisioned him to make it for you. But you have bough it from him right? I wonder how much whould a custom nixie tubes cost. I too hope that it will remain glowing fine.

Ron is such a great man. I'm curious what comes next out of his artist
workshop.
