I wonder if anyone ever tried adding a few iodine crystals to a nixie? I know
it’s added to some plasma tubes to give a certain plasma color (i have
onenice blue tinge to the plasma glow)
Hmm

Get a sufficiently precise spectrogram?

My point really is, is there a way to determine the composition of the gases
inside a Nixie tube? It would be interesting to know, as this is something that
is lacking in datasheets.
I’ll try and dig up the Russian paper.

Here's the text in question...
In a 2011 email to me, Roger Wolfe, a Burroughs engineer, recalled the
team’s first fragile attempt: “We put the tube on life test overnight. When
we came in the next day, so much cathode material had sputtered onto the
dome of the tube that the numerals were no long
Ghosting is usually caused by changing the cathode value too soon after
turning off the anode at the end of the display time for that digit. Try
waiting a millisecond with all anodes off before writing the next cathode
value.

There is some information in this article, presumably first hand
information from a Burroughs engineer, on the extended life when mercury

It's only worth what someone's willing to pay for it. I can only speak for
myself but I do think it's exorbitantly overpriced as well. Is it really
worth 4 of Dalibor's zen clocks?

It is a nice piece of work, mind you.

Hi Martin,
Yes - I se
I recently saw a post that suggested that the addition of a mercury dopant to
Nixie tubes does not confer the protection that we have all been led to believe
- apparently the Russians made a study suggesting this to be the case.
Regardless of whether this is true or not, I was wondering if there
The datasheet I found online says the operating voltage is 100V, and 2.5 to
4.5mA. So I would start with the midpoint, 3.5mA
If your supply is 170V, and the tube is 100V, the resistor is easily
calculated: R = (170-100)/(0.0035) = 20K
I'm very suspicious about the 100V operating voltage; it see
Have you asked Brent Hilpert who owns the site you linked too if he has the
datasheets? He has been very helpsome when i have asked him about other
equipment with dekatrons and the E1Ts.

I would recommend a value around 18k for 170 volts. That's what I run in my
clock that has IN-8 seconds tubes.
Of course, if tube life is a concern then I would also add in a motion
sensor and a phototransisitor to automatically dim the tubes in low light.
These two things will help any nixie live
I have had a Canon X61884803 calculator display board for some time and I
am in the process of trying to use this directly rather than pull the tubes
from it. I figured out the basic circuit for it and put together a lash-up
to drive it. Naturally it is multiplexed and LTSpice shows that 120Hz
I do not have those. Early this year I purchased 10 NOS IN-15A's and 10 NOS
IN-15B's as the prices were quite cheap since there really is no demand for
them. Have been trying to decide about what to do with them. Using IN-12's
for the letter I and O, there are a few words that can be spelled out
Seen a lot of discrepancies for what people recommend for an anode resistor. I
want to prolong the tube life as long as possible as it's going in a full
custom clock that's gonna be a gift.

You must be careful with the filament. The filament will accept whatever
current you give it. Overtime, constant voltage source on the filament is
problematic. As such - for sure- drive the filament with an AC wave
There is lots of corollary info on this blog regarding the filament.

I'm planning to use an LM9022 based supply. Yes, it's out of production,
but apparently it's the same as an LM4871.
And
Nice!
I like the simplicity of the design.
