I would be afraid that when You want to change anything on your metal
flange system, You have to buy another parts, have to search for them etc..
On glass system You can change everything yourself, it is cheap. And once
the connection in glass is made, You can be sure it is vacuum tight (it is
visible - nice smooth connection), so You can focus on right places in case
something is leaking.

I hope You will come up with some homemade nixies soon ;-)

  I am currently training my glasswork "skills", which is really a lot
 of work, so this eats up all my spare time at the moment. I will have more
 time in the next months, so for me it will take some more time, sadly.
 Hence, there is nothing to report for my website as of now :-(

Hi Dailbor,

you mention a key point: I tried a setup with ordinary refrigeration 
tech hoses before (just like the ones on your website) and I also used 
transparent silicone hoses. The result was: It was not tight. There were 
leaks all over the place.


That is why I want to get rid of this problem by using modern flange 
systems. It is a bit expensive, but it is money I only have to spend 
once. It saves (me) a lot of time and grief, but of course, everybody 
has to find his or her own way. There are many ways of more or less 
successful Nixie tube making :-)

Making a glass vacuum system (filling manifold) is quite easy with 
glassblowing torch and blowhose. I tried several T-joints and when I 
was satisfied with function (look could be better) I started to make a 
glass system. I am not decided how to connect it to vacuum pump, I 
realised, that silicone hoses (I use) outgasses to much..


Vermiculite is curious material, it is very light, it has almost no 
thermal capacity, it is good thermal insulant, so the cooling is very 
slow. The heat from the annealed glass is enough.

Hi,

for easier maintenance and also due to my dissatisfactory
glassworking skills I will use a standard vacuum flange system.
There is a very good needle valve I used once in the university
that I would love to have for my setup. It allows you to let in
the gas very (!) smoothly so almost any pressure can be achieved
given the vacuum system is not leaky. The bad part is that this
valve costs 200 EUR, which is much for a student (if you have to
pay rent and stuff...). But it is a one-time investment that will
definetely pay off.

Interesting about the vermiculite, I did not know it was
sufficient to just put the glass in there, I thought some kind of
active tempering was still required.

Making a glass vacuum system (filling manifold) is quite easy with
glassblowing torch and blowhose. I tried several T-joints and when I was
satisfied with function (look could be better) I started to make a glass
system. I am not decided how to connect it to vacuum pump, I realised, that

Vermiculite is curious material, it is very light, it has almost no thermal

Hi all,

Jonathan,

The 74141 contains a ~55V Zener diode on each output. It isn't really intended 
to perform blanking, despite what you might be led to believe from the truth table.


The Russian chips are said to have a higher voltage Zener diode than the 
American parts, so go with those. Even so, you will need to reduce the HV to the 
best compromise.

[neonixie-l] 74141's and blanking

[Jonathan]

Hi all,

I'm making my first clock that has to be set by the user instead of self 
setting. And the leading digit needsl to be blanked, as the woman it is for 
doesn't want to see the zero.

Anyway, I am using the blanking feature of the 74141 for the first time.  It 
seems that some of them don't blank as well as others and to get them all to 
blank I have to dial the anode voltage down or lower tje pwm duty cycle which 
prevents max brightness during the day. One of the 74141s blanks well and so 
does a Russian equivalent that i have. So, am i doing something wrong and is 
there anything I can do about it? I suppose I can cherry pick through my stash 
for chips that blank well.

Thanks!

Hi,


Do You have any info about your progress on your site?


I am currently training my glasswork "skills", which is really a
lot of work, so this eats up all my spare time at the moment. I
will have more time in the next months, so for me it will take
some more time, sadly. Hence, there is nothing to report for my
website as of now :-(

I have a plan, though, for a simple glow lamp with two cathodes
that I will be able to build with my primitive tools and
especially primitive burners. Let's see :-)

Hi folks,

the only tube with a flashed getter I know of is the XN-1:
http://www.tube-tester.com/sites/nixie/data/XN1/XN1.htm

To be honest: I will not use getters at the moment. There is
so much glasswork to figure out for me, that is the part that
I will focus on in the next months. :-)

Hi Dylan,

flashed getters are not used in nixies (I havent seen it at
least), just some VFD tube use flashed getters. Flashed
getters leave a coating on a glass envelope of the tube - we
don't want that. I think that kind of getter needs only
initial activation by heat which could be done by induction
heating as well as in the case of flashed getters. Look to
IN-14 nixie, there is exactly the same pellet.

The only matter to solve will be attaching the pellet to a
wire, but I think that will be possible to do by spot
welding - inspired by IN-14.

Thanks,

Dalibor

Hey Dalibor and others-
   I don't feel that these are the right getters for
nixie tubes.
   The literature lists them as thermally active- they
only absorb if you put them somewhere hot.
   Many styles of getters are made this way; most tubes
do run quite hot, beacuse of the filaments..

   There isn't anywhere in a nixie tube that is
constantly 100C-200C. (That's part of the magic of
nixies, of course)

   You really want some flashed barium getters; they
absorb gasses at any temperature.

Re: [neonixie-l] Re: nixie makers: getters

[Dalibor Farný]

Hi,

thats the same with me, I also rather works with glass than write on web
;-) I am making exactly what You wrote - simple glow lamps, filled by
argon. I seal them and run them as long as possible. I make one with
pressure just enough for the glow to cover all the cathode evenly,
stainless steel electrodes spot welded to dumet. After 14 days of glowing
(@250V) the dumet started to sputter (or it was sputtering all the time,
after that time it was visible) and probably caught some impurities and
lowered the pressure (worked as a getter), so the sputtering became faster.
And yesterday some problem occured in my power supply and the voltage went
to 400V, so today all the bulb is covered with sputtered material ;-)

I am still waiting for stainless steel foil from USA, when it arrives, I
will start to etch nice (I hope so) electrodes.. Also going to prepare some
alumina solution to cover the dumet to prevent from sputtering.

I have mercury dispenser, used in fluorescent lamp. I think that it's

mercury, but I hate this method:/.

I can't to tell that Ron is right.
 If you want low voltage supply (below 180V) and long life for nixie, 
you should have the atmospere Ar, Ne and Hg.
I have old polish documets about AC and DC-PDP (plasma displays) and 
there is a lot of informations about good mixtures.


I haven't glass lathe so far, thats why I can't prepare so beautifull 
glass wafers as Ron:(

Good reason for not using mercury in your tubes! Pick a low

not really necessary in tubes operating at nixie tube pressures.
Just do a good bakeout and you will be fine.

This is interesting - early nixies had a life (whatever that may mean) of 
only a low number of 1000s of hours - later tubes with Hg went up to 
200,000 hours.

If you want long-life, anti-sputtering seems essential - special non-Hg 
tubes were made for aircraft and subs etc. (where Hg is absolutely not 
allowed), but otherwise pretty much every later tube has it.

The cathode technology was very well understood by then - why use any Hg if 
it wasn't necessary?

Hi folks,

the only tube with a flashed getter I know of is the
XN-1:
http://www.tube-tester.com/sites/nixie/data/XN1/XN1.htm

To be honest: I will not use getters at the moment.
There is so much glasswork to figure out for me, that
is the part that I will focus on in the next months. :-)

Hi Dylan,

flashed getters are not used in nixies (I havent
seen it at least), just some VFD tube use flashed
getters. Flashed getters leave a coating on a glass
envelope of the tube - we don't want that. I think
that kind of getter needs only initial activation by
heat which could be done by induction heating as
well as in the case of flashed getters. Look to
IN-14 nixie, there is exactly the same pellet.

The only matter to solve will be attaching the
pellet to a wire, but I think that will be possible
to do by spot welding - inspired by IN-14.

Thanks,

Dalibor

Hey Dalibor and others-
   I don't feel that these are the right getters
for nixie tubes.
   The literature lists them as thermally
active- they only absorb if you put them
somewhere hot.
   Many styles of getters are made this way;
most tubes do run quite hot, beacuse of the
filaments..

   There isn't anywhere in a nixie tube that is
constantly 100C-200C. (That's part of the magic
of nixies, of course)

   You really want some flashed barium getters;
they absorb gasses at any temperature.

Re: [neonixie-l] Re: nixie makers: getters

[Dalibor Farný]

Mercury + stainless steel cathode are the best combination for the longest
lifetime of the tube. Another possibility is to use molybdenum cathode, but
it is not easy to obtain (0.1mm shim), I dont know how to etch it, it is
quite brittle to work with and difficult to spotweld to lead-in-wires. I
will fill mercury by mercury dispenser - metal compound, activated by
heating, this procedure relieve the mercury.. Similar to flashing the
getters,

Re: [neonixie-l] Re: nixie makers: getters

[glasslinger]

Good reason for not using mercury in your tubes! Pick a low sputter cathode 
metal so it isn't necessary. Also, getters are not really necessary in 
tubes operating at nixie tube pressures. Just do a good bakeout and you 
will be fine.

Re: [neonixie-l] Re: nixie makers: getters

Yes, right, but it works for tubes like B-5025 series, since they are 
mercury-free and the getter mirror is on the back of the tube.

Re: [neonixie-l] Re: nixie makers: getters

[Dalibor Farný]

Thats exactly what I mean, I will use flashed getter for testing - I will
disassemble some old TV tube as Ron suggested. But I want to use right
getter later..

Do You have any info about your progress on your site?

Re: [neonixie-l] Re: nixie makers: getters

[jb-electronics]

Hi folks,

the only tube with a flashed getter I know of is the XN-1:
http://www.tube-tester.com/sites/nixie/data/XN1/XN1.htm

To be honest: I will not use getters at the moment. There is so much 
glasswork to figure out for me, that is the part that I will focus on in 
the next months. :-)

Hi Dylan,

flashed getters are not used in nixies (I havent seen it at least), 
just some VFD tube use flashed getters. Flashed getters leave a 
coating on a glass envelope of the tube - we don't want that. I think 
that kind of getter needs only initial activation by heat which could 
be done by induction heating as well as in the case of flashed 
getters. Look to IN-14 nixie, there is exactly the same pellet.


The only matter to solve will be attaching the pellet to a wire, but I 
think that will be possible to do by spot welding - inspired by IN-14.


Thanks,

Dalibor

Hey Dalibor and others-
   I don't feel that these are the right getters for nixie tubes.
   The literature lists them as thermally active- they only absorb
if you put them somewhere hot.
   Many styles of getters are made this way; most tubes do run
quite hot, beacuse of the filaments..

   There isn't anywhere in a nixie tube that is constantly
100C-200C. (That's part of the magic of nixies, of course)

   You really want some flashed barium getters; they absorb gasses
at any temperature.

Re: [neonixie-l] Re: nixie makers: getters

[Dieter Waechter]

You will find the flashed getters on the back of the tubes, but not on 
all. Only SH4, SH5 do have these (The "SH" designation are my own 
designations and stand for "shape", I need that for my tube matching 
system) there are 7 known shapes of the B-5025 tubes.

Hi Dieter,

I don't see any flashed metal in B-5025, just some stripes of metal on
the top. What I understand under term "flashing getter":

"Flash gettering means, chemically active, comparatively volatile
metals-mostly metals of the alkaline earth group are evaporated by
heating their supports at the conclusion of the pumping process. The
metal vapor before and during condensation reacts instantaneously with
all other than noble gaseous residues and forms on all cold parts of the
tube, particularly on the tube walls, the so-called getter mirror."
