Hi All, 

 

I got al time ago a set of nixie bulbs about what I liked to know more data. 

I was  in the mind that they were for 230V, but that resulted in a little 
‘bang’ and a electric defective bulb.

I opened that bulb  en as you cansee at the second photo one of the electrodes 
is blown off.

 

Is there anyone who has the necessary data to run the bulbs properly? 

Most important are the ignition voltage and the maximum operating current, but 
any more useful data is highly appreciated.

 

Kind regards,

  eric

Yes, that is the story as I wrote earlyer in this thread.
I guess not all tubes were destroyed. Small parts of the production ended im 
private hands and collections. Some items were for sale as ‘not functional’. 
I ever could buy one for my tube collection for a realistic price.

XM1000 is a modified copy of the NIMO made by Telefunken. 

In fact, these tubes should have been destroyed after a lawsuit by NIMO, 
because Telefunken ignored their patent. However, it seems that much of this 
tubes has been preserved.

RE: [neonixie-l] Re: Helping Nixie Tubes Fire in a Darkened Room

[Tidak Ada]

The problem is that a 365nm  LED has a much wider spectrum, definitely 
producing ozone. I have a floodlight with a 365nm COB-LED that I can smell. OK 
It’s a 10W chip, but despite that.

Further, it’s fine to reduce the LED’s burning time to avoid their light and 
color. That’s the main reason to start  with only pulsing during transition of 
the figures. I think the UV pulse may be short enough that it will be not 
visible

 

The UV trick works also fine with dekatrons and other trigger tubes.

 

Cheers,

You won't generate ozone with 365nm. You'd need shorter wavelength UVC for that.

This particular tube (MG-17G) has segments with no anode screen in front of the

any visible base lighting.  I will try 365nM LED's when they arrive and may use 
them if there is less noticeable, visible light.

 

Thanks for the suggestions!

RE: [neonixie-l] Re: Helping Nixie Tubes Fire in a Darkened Room

Why  not a trial with UV-LED’s 365 nm is a useful wavelength and you don’t need 
to use then at full power. 

You can use them in a pulsed mode only during refresh of the display to avoid 
too much O3 production. Iyt is not as hazardous as the use of ß-radiating 
isotopes as used in rigger tubes.

I think the best approach would be to increase the HV. If you look at the 
discussions of glow physics in Weston or Acton for example, the lag in striking 
a glow from dark (which is what we're talking about here) is reduced by using 
an anode voltage materially above the threshold striking voltage. Overdrive is 
a matter of tube current rather than anode voltage per se, so a simple 
compensatory tweak to the current-limiting resistor value will get you back to 
the same tube current as now. The cost of the change will be a little extra 
power dissipated in the current-limiting resistors, but that should be 
immaterial in most circumstances.

 

Jon.

I think you mean 10-50 microns (which is 1000 timer lower), not 10-50 Torr. One 
atmosphere of pressure is 760 Torr (760mm Hg).

I've seen neon-sign texts stating the need to get below 1 micron for proper 
bombarding, and I imagine nixie tubes are similar.

A long time ago (55 years), I had to use this Picker counter at university. 
We had to calculate the half-life decay of Cesium-137
I get still a raise in hartbeat as I remmeber the reading of those running 
dots.

Who in hell has devloped this ugly machine?

RE: [neonixie-l] What is this tube ?

[Tidak Ada]

They are NO magic eyes, but VFD display’s like every other VFD 7-segment 
display the indication is by steps every dot (or triangle) is on or off 

The Russians also had things like this, but with round dots and about the 
length of a IN9.

Remarkable is the  “zero” level display with up-down indication. I only saw 
such with LED’s. Red triangles and a green line in the middle to tell level 
zero just for FM discriminator tuning ‘zero level’.

I have seen quite a few listings for Camera and consumer electronic related 
items from Ukraine. one's I have purchased on E-bay the sellers often write to 
be sure that I am aware of what might be a two month shipping delay.  selling 
on e-bay is one of the few ways for someone to make money under the invasion 
conditions.  SO far so Good as far as receiving the goods.  Currently expecting 
some empty recording tape reels in pastel colours.

I've never broken any of the Elesta EZ10, EZ10, EZ10B, ECT100 or ECT101 that I 
own when using them in their original sockets.

I do have an old tester for these which contain a pin straightener which I 
always use before inserting them in the socket, I also use a pin of the same 
diameter to insert into each socket receptacle so that they aren't to tight 
before I insert an tube in a new socket.

The only broken/damaged Elesta EZ/ECT-series I have are those that were 
alreaday bad when I bought them.

I can recommend you that you make a pin straightener as well as a tool to widen 
the receptacles. You can either order these from manufacturing companies who 
can make them out of aluminum, or you can make them yourself by making circuit 
boards with the correct holes, plus some mounting holes for screws/nuts to keep 
them in place, and then stack a few of these boards on top of each other and 
drill conical holes through the first and second with a conical drill bit used 
for Dremel tools for the straightener, the widening tool can then be made by 
placing pins of the correct diameter in the straightener and then stacking a 
few circuit boards on top of the pins and soldering the pins to these boards. 
Pins can be bought on eBay.

Below is a photo of my Elesta EZ10A/10B tester with the pin straightener above 
the text GAUGE.

Any experience with ELESTA EZ10 A and B dekatrons (7pin miniature size) in this 
matter? These tubes have 13-pins and need special, ceramic, very hard to get 
sockets.

I guess it depends on the socket you’re using.

I’ve seen ceramic with floating pins just like the bakelite versions.

If the ceramic version is a tight fit, why not just loosen them up before you 
insert the tube.

 

I’ve killed many IN-18 tubes not knowing the solid ceramic sockets I had put 
that much tension on the pins.  It would work, but a short time later (day or 
week), the tube would die.  So, it took a while to figure out that it was the 
socket instead of the tube or electronics killing them.  Now, on new sockets, I 
insert/remove a dead tube in many times while adjusting the socket to make sure 
it is more loose.  Like you, I would rather kill anything else other than the 
tubes.  I’d rather a poor connection over one so stiff that it’s a tube killer.

 

Adjust – meaning to bend the socket of each pin to make it a much easier insert 
force.

Some people say ceramic sockets crack tubes at the pin and cause them to go to 
air and that you should use bakelite sockets

 

Some of my friends say they've lost tubes to it, some of them say they've 
socketed countless tubes without issue.

 

Ive got some ceramic sockets and some 9-pin digivacs and biquinary nixies I'd 
rather not kill. So what's the deal?

RE: [neonixie-l] Self-introduction & tube trading

[Tidak Ada]

Hi Duncan,

I have some Elesta EZ10 A/B tubes (1MHz resp. 500kHz) that could do the job if 
I can get the MHz of the 4MHz TCXO at 400kHz in a 'fair' way. There must be a 
way using heterodyne mixing, but that goes 
beyond my technical knowledge. HP used the technology in some counters in their 
early years.
The trouble is that the EZ10A is a hydrogen filled tube. Hydrogen diffuses 
through glass, so there is a good chance that the tube is dead.

Another less fair way is to use (High levl)TTL or CMOS chips there. After all, 
the TCXO is also a semiconductor oscillator.

The lower frequencies have to be divided by some Sylvania 6879 dekatrons.
The display part should exist by a GS12C, GS12D and GC12/4B and some 
10-counters from the Ericsson house.

I am at the level to set up a test circuit for the Elesta's, but time and age 
are the bottlenecks.
Anyhow, I like to save some of the Elesta's for my tube collection. 
Another guy who may be able to help you is Graham McGuire, also a Neonixie-L 
member

Cheers,
  eric

Thanks for the warm welcome!

Michail: part of the challenge for the 1j24b CPU is to build the whole thing 
without any silicon. Building the muxing and decoding circuitry for the 5971s 
without using a PIC is part of the fun! Of course, sourcing high-voltage 
germanium diodes is a slog.

eric: I had read Joe's research radiomuseum.org but did not know that we shared 
an _alma mater_. Thanks for the connection and the pointer to 
tubecollectorsassociation! Re: quartz oscillators, how did you get the 
frequency down into the dekatron range? IIRC, most dekatrons don't work until 
you're down in the tens of kilohertz.

P.S. correction to my original email: I have a large quantity of ILC1 1/7 VFDs 
not ICL1 1/7.

Hello Duncan,

Interesting projects.

About those Russian rod-gridded tubes I will refer you to TCA-member [ 
tubecollectorsassociat...@groups.io ] Joe Sousa (MIT). He did a lot of research 
on these tubes. His reports are also published at Radiomuseum.org [ 
https://duckduckgo.com/?q=radiomuseum.org+english+language&hps=1&atb=v261-1&ia=web
 ]

I had plans for a clock with moving coil meter readouts, but I stopped after 
calculating the power consumption of the project.
Intention was to start with a TC X-tal oscillator (400kHz) then count down with 
dekatrons to the 0,1Hz region. Then a clock counter with a D/A converter to the 
meters.

Unfortunately, the power consumption is irresponsible, especially in this time 
of scarcity and hi prices in Europe.

Success!

Hello everybody!

I'm Duncan, an American software engineer by day and vacuum tube enthusiast 
when I'm not distracted by other things. I have an unreasonable number of 
pokers in the fire right now, but they include:

* a clock based on each of J.B. Dance's Electronic Counting Circuits
   chapters (how low can I get the active part count without involving
   silicon components?)
* tuning fork timebase for the above clocks
* 1j24b (Russian subminiature rod pentode) CPU
* 1j25r (even smaller than 1j24b) headphone amplifier

In particular, I'm interested in hearing from the experts what kind of fun 
tube-based displays I might've overlooked for the 1j24b CPU. My current plan is 
5971 13-segment tubes (I'm too poor for that many 7971s), but I don't really 
know what's out there.

===

I'm also interested in trading to get some of the tubes I admire for their 
aesthetics. I consider the National NL-90X series (NL-900 no decimal,
NL-901 left decimal, NL-902 right decimal, NL-908 both decimals) as well as the 
Ericsson GR10N tubes some of the most beautiful ever manufactured and would 
love to trade for/buy some. I have a large number of enormous
ICL1-1/7 VFDs as well as some tiny National NL-4998 nixies for trade. I also 
have the above mentioned sub-subminiature Russian tubes (1c38a triode, 1c38a-q 
Chinese variant triode, 1j25r pentodes, and tg5r
thyratron) as well as their slightly less sub- brethren (1c1a triode, 06p1a 
pentode, 1t1a thyratron) for anyone who wants to build out their collection of 
oddities.

Out of the bunch that I own of these only a few are running (and maybe half are

I took the bait today and bought the version with the assembled PCB. Total cost 
is $38.11 US including shipping. I cant even procure the individual parts for 
that price. I'm pretty sure the DS3231 is fake, so it's still a bargain even if 
I have to replace it .

RE: [neonixie-l] Re: nixie clock using trigger tubes

[Tidak Ada]

Did you already try UV-LED’s? Banggood and Ali sell COB-chips up to 365nm 
wavelength 10 to 50W power and also a 365nm cut-of filter. That gives you the 
advantage of no visible light for small money, However, you don’t need the full 
power of a 10W COB-chip of course, what saves power if used with a lower current

I tried this back when building my NE-2 ring-counter based clock, and there it 
didn't work. The red neon light simply didn't help the striking process, in 
contrast to blue light.

Note that we're talking about two totally different processes here. The light 
emitted by the neon gas has a wavelength (colour) determined by the physical 
properties of the neon atoms, while the light needed to help the striking 
process must have photons with sufficiently high energy (sufficiently blue 
colour) to kick an electron loose from the electrodes, which depends on the 
physical properties of the electrode material.

I do have some near-UV LEDs (400nm) but the clock is line powered and I don't

Actually, I'm not even using the 'trigger' function of these tubes, they are 
just used as neon lamps with a large difference between strike and maintaining 
voltage. It's this difference which allows one to build counters with them. 
I'll publish a more detailed description on my website later on.

Some may know that I built a similar clock over ten years ago:
  http://pa3fwm.nl/projects/neonclock/
That clock used regular NE-2 style neon lamps for the logic; unfortunately it 
became unreliable, as the lamps' properties changed with time. I hope the new 
clock will turn out to be more reliable...

Before the prices rise out of sight, I'd like to have a few magic eye driver

interesting things. Most of the kits I've seen are so-called "VU" meters which 
expect an AF signal. I can work with that.

 

I'd like to do this cheaply but reliably. The goal is to have several arranged 
in a group so that I can use them with my Halloween displays.

I believe that the Monsanto MAN-1 was the first commercially available 
7-segment LED display.  It was introduced in 1969, but was so expensive (~$300 
each, or $175 in 1000s) that it didn't get much use until later in the 70s.

 

I was surprised to find that the Numitron (or its ilk: Minitron, Apollo IEEE, 
and Wamco, and the Russian IV9 and IV16) was also introduced around that time.  
All of the data sheets I have (that are dated - many are not) were published 
around 1972. The Numitron was certainly a mature technology by that time, but 
given that its fundamental technology had been available since the 1920s, I 
would have thought it to have been available much earlier.

I found this old pc board brand new in sealed original plastic bag for an 
8-nixie device.  The Nixies appear to be the ZM1000 base type.  Board is 
labeled  85-560-2 and 060172 .Each nixie has 3 IC's going to it and maybe some 
power or wave shaping by 2 IC's on the left.  The board is double sided FR type 
material  about 18 cm x 9.5 cm  Any help appreciated

Thanks  Pharma Phil

I too have similar NE-2G bulbs that are white colored and glow green when 
powered. I bought a pack of 20 a while back from China. They are about half the 
size of what a traditional NE-2 measured. However, I have about 10 or so 
NE-2G's that I purchased from Radio Shack back in the 1970's. Those have a very 
bright glow and no hint of orange.

 

I tried some NE-2G's with one clock as the colons. I had the tube LED's lit 
green and thought it might look "different". However, it looked better with 
straight NE-2's (or IN-3's) rather than green. I am rather used to the 
green/amber motif as that was something of a common color scheme for electronic 
devices around 2000 (had a Motorola cell phone with that color scheme in the 
display) and even my 2000 Honda Insight has an amber/green digital dash.

Ever thought at polaroid film?

Enhances the contrast significant because of reduction of the incident licht, 
does not affect the color and as a slight reduction of the brightness.

There are  even light colored Pola-foils A long time ago I bought a red 
Polaroid filter from Monsanto for enhancement of -in that time weak lighting- 
LED-displays

I've done a few tests in the past. With the acrylic that I got, the result was 
as follow:

translucent red: converts the orange glow to red, reduces contrast and 
brightness

translucent orange: keeps the orange glow, slightly improves contrast, 
maintains brightness

translucent brown: keeps the orange glow, slightly reduces contrast and 
brightness

Because they are easy to remove I want to put a perspex front on the device to

I was going to use clear perspex / Acrylic but I find that I can also get red

I was just wondering if anyone in the group had an experience or opinions on 
this and the suitability of using coloured instead of clear?

Thank you all.

A correct Insurance is not an ordinary fire and burglary insurance. 
What  you need is a special collection insurance or a special  valuables 
policy. Of cource for a corresponding premium.

Here are some detailed photos of the ZM1200 which arrived today. 

There is no documentation and the packaging is half of the original box with 
the foam liner breaking down, the tube is wrapped in old corrugated paper and 
tissue, the box looks as old as myself. 

The pins have age discolouration as would be expected.

The tube is sold as seen and was described as NOS although that is no guarantee 
that it is a working tube.

Unable to source the sockets for this tube as they are even rarer than the tube!

I have described this as best as I can and without prejudice.

Hi,

 

Finally I finished the vector artwork of the Bourns logo

 

Because I don’t know which file type you can ‘eat’ I send you a list of what is 
possible (see attachement)

Let me know what fits you the best. Then I can send you he files. The final 
size is 350 × 350 mm (13,75 × 13,75 in.), but you can scale it to every size 
you want (using a suitable vector program).

Do you perhaps want to place the in the horizontal bar in the Bourns logo ?

I'm still toying around with a logo for the theoretical NixieBase project. I 
need a really good hi-res scan of the words "Burroughs Corporation"  as used in 
their documentation and packaging so I can trace the capital letter "B". I'd 
like to have the "B in a circle" logo as well.

 

Scan parameters:

1200dpi or higher

8 bit gray (256 grays), not color

Saved to a lossless filetype such as TIFF, not a lossy filetype such as JPEG. 

 

TIA.

Hi,

 

I have a Nixie driver. Made by TEC-LITE a long time ago with one dead 
transistor, white ceramic with black top TO-106 (?) it says CDC-TEC-303 on the 
white ceramic, Googling and searching some transistor data-sites haven't come 
up with anything.

 

Does anyone here know where I can find a datasheet for this transistor?

 

I've included some photos of the transistor as well as an old ad.

RE: [neonixie-l] How dangerous is 150V - 170V DC?

[Tidak Ada]

It's not the voltage that causes death the, but the current!
Remember an electric fence for cattle has a voltage of several kV, whereas the 
current is limited to a few milliamps. In general a current above 10 mA is 
considered as deadly. Lower currents are painful, unpleasant or symptomless.
The strength of the current is depends highly of the resistance of the path it 
follows. Here in Netherlands the mains voltage is 230V, what results in peaks 
of 400V at the top of the sine. If you stand in leather shoes on a wooden floor 
it gives a very unpleasant feeling, that gives a muscle contraction that lets 
you mostly to 'untouch' the contact the wire. But in case you have sweaty 
fingers and naked feet, it may be deadly.
In my working life I was involved in bio-physical research on smooth muscle. 
There was a strip of muscle placed in a bath with a physiological solution 
(Ringer's) between two electrodes for stimulation. The current pulses we needed 
to activate the sample where in the range of several amperes! The main of the 
current was lead trough the Ringer's solution that functioned as a 'shunt'!!

Once, I made an unintended contact between my upper lip and a scope CRT under 
800V, but a current limited by the EY50 diode to a few mA's, I survived, but 
was ferry impressed!

Anyhow, it is important to AVOID contact with voltages over 30 Volts, the 
voltage was used in 'farm radio's' in the US.

Thanks for sharing Eric. I'm not quite sure how Jogi would manage to determine 
the max / min range for anode current experimentally, as I'd expect that to be 
worked out statistically from the behaviour of a large set of tubes with a 
target operating life in mind - feels like the kind of thing that only the 
manufacturer could do. Until we get more definitive data, I'd definitely keep 
the current on the low side as that's less likely to damage the tube.

 

Jon.

Hi Jon,

 

Thanks for your efforts !

Anyhow, That Vmax of 265V makes sense as well as Imax = 1.3mA does.

I will also look around and of course I will share all information.

Sorry Eric, I don't have any definitive data on EZ10A. Piecing together info 
from several articles and looking at the component values in various circuits, 
I think the typical anode current for EZ10A is 1.3mA with a maintaining voltage 
of 265V. The EZ10B typically operates at 1.5mA, which explains the note of 
caution in Dance (the same warning is also given by Elesta in their 
documentation on EZ10B).

 

I believe the detailed information on EZ10A is contained in Elesta's Technische 
Mitteilungen Nr 14 from 1960, but I've not yet managed to find a paper copy or 
a scan of that document. If anyone has that info, please get in touch!

RE: [SPAM] [neonixie-l] Re: New to dekatrons looking for advice.

[Tidak Ada]

Does anybody know the difference between specs of a EZ10A and EZ10B.

EZ10A is known to run until 500KHz, whereas the EZ10B should run up to 1MHz.

 

The EZ10A has a kind of Penning mixture; EZ10B is said to be filled with 
hydrogen (very triggy in aging ! ).

 

For so far my knowledge.

Reading in Dance’s book I learned that they are NOT interchangeable in voltages 
and currents. EZ10B is described well by Dance, but thee EZ10A is only 
mentioned with the warning. So my question is what are their specs…..

 

I have three of each of them plus three sockets. Plan is to make a divider to 
run down a 4MHz OCXO to frequencies of 4, 2. 1, ½; ¼ Hz to feed my clock 
project.

As a general rule, dekatrons like to be spun. Providing you are operating them 
well within their anode current limits and the glow is moving around the tube 
they will be very happy for a long time. I do have a suspicion (that I cannot 
back up with data yet) that use rather than storage may be the best strategy 
for keeping the high speed tubes alive...

RE: [neonixie-l] Letterbox CRT Tube

Onderwerp: [neonixie-l] Letterbox CRT Tube

 

Afternoon all (or morning, depending on where you are).

 

I often pickup boarder line scrap equipment if it has interesting display tech 
in it, hence why I am a member here I guess (rarely find nixies, but have 
scored a few panaplax, planar and HP LED displays this way). I have, over the 
last year or two acquired a couple of patient monitors (Edwards Lifescience / 
sometimes Baxter) with a fairly odd very rectangular CRT in it that I thought 
was worthy of mention on here. 

 

Its a Computron branded assembly, tube part 115-336 DMK 5X9, made by CPT as a 
MI5901P4AV - CPJ 5X9. White phosphor (amber filter on the plastic).

One nice thing about this was that the monitor had a dedicated computron 
115-DMX driver card for the tube, which I suspect takes a digital line sync 
pulse and a intensity signal then handles the scanning itself. Its a fairly 
well known card, I guess Edwards just bought the tube and card as a module to 
fit to their (insanely complex 1 foot square) main board. 

 

Attached is some pics. Sadly of the three of these I have acquired over the 
years, two have quite noticeable screen burn, but I thought it would make a 
good clock project tube so at least I have enough parts for developing one 
certain working one, rather than building something with only one being 
available - always a risk! Just need to come up with an enclosure design and 
possibly wait 30 years until I retire and have the time! Nice little micro 
controller project to produce the rasters and graphic sprites. Ideas for making 
a magnetic deflected tube look good naked would be good though - I have always 
liked the elctrostatic deflected projects with a nice polished tube on 
display...

 

Hope this is of mild interest, never seen such a geometry on a CRT before so 
thought I would share...

 

Cheers,

- Alex

Hi All

Here's two pictures of a nixie/trigger tube clock built by Massimo Capra in 
Barcelona. Still to have a clear acrylic cover fitted over.

Details are here:

http://www.sgitheach.org.uk/nixie8.html

I have run out of PCBs but could be convinced to get some more manufactured if 
there was sufficient interest - please PM me and I'll gauge interest. It is 
unlikely I'll do any kits again. The design uses a custom wound mains 
transformer that is not hard to have made. The Z700U trigger tubes are 
available in their thousands from a UK supplier.

Note that the Z700U has a priming electrode so it doesn't have problems 
operating in complete darkness.

Enjoy

Grahame

RE: [neonixie-l] loose-pin sockets

[Tidak Ada]

It’s not the insertion of the tube that worries me, but the long term stress 
due to slight misalignment of the bushings. That concerns particular hydrogen 
and helium filled tubes. Keep in mind tubes like EZ10A and B have a very dense 
13 pin socket that needs narrow tolerances in alignment. It’s therefore not 
wise to use PCB-sockets, a floating wiring is better.

I do mine in 2-steps:

*   Low-insertion socket pins soldered to PC bpard
*   3D-printed collar that sets over the pins. It's mostly for aesthetic 
reasons, because the pins dont fit snugly into the collar. The collar certainly 
helps guide the tube into the socket. However, you should avoid 
plugging/unplugging unless necessary.

The radiation hazard is comparable or less that the hazard of a concrete or 
natural stone wall in your house. however the wall is more less healthy, 
because Radon is an alpha radiating gas that you inhale in your lungs

Anyhow, an hour in an airplane at 10,000 ft gives a considerable higher dose.

None vs none.  As soon as the low level X-rays from TV sets were discovered and 
became and issue (two different events), several things happened

1) All new CRTs had their faceplates made out of leaded glass.
2) the damper tube was made from leaded glass*
3) hard high voltage limiting was instituted.

* A properly made damper tube would not generate X-rays regardless of the 
voltage applied.  The plate cylinder had to be a little bit out of 
concentricity with the filament to produce X-rays.

There was an Amateur Scientist article about how to use a damper tube and a 
home-made Odin coil to make an X-ray source.  Several fuzzy X-rays were 
published.

I made the Odin coil but I could not get any X-rays.  My tube was in good 
alignment.  It took prowling through the inventory of the two TV repair shops 
that tolerated this nerdy kid before I found one that worked.

The results were still lousy because the X-rays emanated from all over the 
anode's surface.  The optical equivalent is trying to take a shadowgraph photo 
of an object using and extremely point source LED vs using light from a 
recessed fluorescent fixture.  Real X-ray tubes use several tricks to make as 
close to a point source as possible.

Anyway, back to CRTs.  I have a Victoreen survey meter designed specifically 
for the CRT industry.  It uses an ion chamber with a super-thin mylar window 
and is calibrated microR/Hr.  I have never detected anything above background 
from any of the TVs or CRT monitors I've owned.

An important point: The current through the filament should be 30mA. That is 
the real reason why resistor network is like it is. A = V/R. Where V=11 (the 
voltage we are throwing away from the 12V supply, R=370 (100+270). So A = 
11/370 ~= 0.03.

Also 42-Ar is a source of ß-radiaiton, that is used in tubes, even starters for 
fluorescent lamps!

 

Anyhow, radioactive isotopes are more frequently used in electron tubes. 
Particular tubes for transmitting and radar purpose. Thorium is allied to 
Tungsten in filaments for HF power tubes to enhance emission and CO-60 is used 
to enhance ignition of TR-cells (Transmit-receive cells), who are used to 
short-circuit the receiving part of an radar system during a transmitting a 
pulse. Thus to protect the delicate electronics in the receiver front-end.

...Also, reading your problem description isolates the issue to the 10s digits. 

The 10s are driven by 7490s whereas the units are driven by 7492s. Do you have 
the right chips in the right places?

I'd also try swapping round the 74141s between the 10s and units to see if the 
problem moves with them - 74141s can fail

Isolate the problem.

RE: [neonixie-l] Re: Small run fabrication

[Tidak Ada]

Acrifix© has a very low viscosity cement for Plexiglas under the name Acrifix 
1s 0117. The trick  is to use a syringe with a needle to apply the glue.

 

Another way is to dissolve acrylic powder (saw dust) in chloroform or a less 
‘suspect’ solvent to make your own glue and after fixing apply a little 
chloroform by a syringe  along the seam.

 

Anyhow, it is important to use a cement that offers the same refractive index 
as the material you use.

If you use clear acrylic, it's tricky to get a perfect cemented joint with no 
visible air bubbles. The few times I tried this, I used excess cement and had 
to spend extra time buffing-out the areas where the cement evaporated. If the 
joint was in an area that wasn't visible, I just left the bubbles/smudges. I 
never attempted to polish a cut surface and cement it; I only bonded the 
'native' surfaces that are perfectly smooth.

 

Surprisingly, it's rather easy to gently heat acrylic and bend it to-shape. 
Years ago I made my own fish tank, and there was minimal distortion, no 
cracking, and no bubbling at the bend regions. It was clear acrylic, and I 
didn't even need to buff it.

 

Also, if you need to sand-down edges, joints, etc, they will buff-out very 
nicely if you are patient. A buffed surface will never appear exactly like the 
native surface, but it will be very close. Even properly cemented seams will be 
invisible with enough sanding/buffing. Reflections from a distant light source 
are the best way to assess the surface smoothness.

Im not making them out of FR4 because of the glass fibers freed by machining i

the XXX paper phenolic is still really good (fr4 has a dielectric of 800V/mil 
and XXX paper has 700V/mil, the LE phenolic which is more structural has 
650V/mil)

 

but if your looking at surface resistivity, yes PTFE is by far the leader. here 
is a table of different laminates and their data

from what ive been reading XXX paper phenolic is fine for RF applications

Hi Jadon,

 

Never mind, there are also those other useful bushings. 

I was in the mind Teflon had a higher dielectric strength than FR4. That is 
important for higher frequencies. However 1 MHz is not really high. 

If you want, I will look for some rest-pieces of Teflon sheet. I can find them 
mostly at ham fests. 4 - 5 mm thickness will be fine. 

Anyhow, I will be content with phenolic (FR4). It’s already fine you can make 
them.

Teflon stock looks about twice the price as an XXX electrical grade paper 
phenolic   https://www.plasticsintl.com/datasheets/Phenolic_Grade_XXX_Paper.pdf

 

The rating is a break down voltage across 0.062"  from 40,000V to 10,000V after 
a 48hour immersion in water so i think that its going to work fine (still 
looking for the specs on an LE phenolic)

 

I have no idea how i would go about slotting for the tabs on those pins, any 
ideas would be nice

RE: [neonixie-l] Re: Playing with E1T-tubes & restoring them

In this context, it might be interesting also to look at two related tubes: The 
E8T and E80T. 

Both are binary tubes, with a functional principle that lies at the base of the 
E1T. Namely deflection of an electron beam.

Those modules are probably just using the standard design for the E1T which you 
can find in any E1T datasheet. I have seen a lot of those modules and they have 
all been standard designs - there are a however a very few 100 kHz and 1 MHz 
designs that use a few more vacuum diodes and also one or more triodes to reach 
the higher speed (the standard module is capable of some 30 kHz). Some of the 
designs use a small trim potentiometer to adjust the cathode current to adjust 
each module for maximum counting speeds but I don't think that your modules 
uses one.

 

Be careful when pulling the E1T from the sockets as the sockets are sometimes 
very brittle and easily break, moisture and old age makes them brittle.

 

Phywe, Leybold, Neva and Frieseke Hoepfner used them in Geiger counters and 
ordinary counters - one module can be seen here: 
http://www.jogis-roehrenbude.de/Roehren-Geschichtliches/Nixie/E1T.htm which I 
believe is identical to yours.

 

You can buy decals, like the ones used on model planes, which you can use in 
inkjet printers and then just wet them and transfer them to the tubes and the 
put an extra layer of lacquer on top to seal them - I haven't used those decals 
in many years now so I am not sure where to buy them right now, but model 
hobbyist shops might know.

Hi list.

 

Some time ago i picked up some nice equipment while emptying an estate of an 
ex-engineer of a large danish medical company.

 

Amongst the equipment i got some kind of prototype with Philips E1T-tubes in 
it. They sit in a Philips 88929/02 "Decade Counting Unit” which i cannot find 
any information on.

 

The unit housed 5 of these, and unfortunately one of them is smashed :(

 

The decals on the tubes is destroyed by moisture (this sat in a shed for god 
know how many years)

 

Anyone with information regarding these 88929/02-modules or the restoration of 
the decals? I’m planning to test the tubes, and if good, clean off the old 
decals and see if i can remake them.

 

Some pictures for your enjoyment:

Any idea about the power consumtion?

For some years I got the idea to build a digital clock working with relay’s.

Calculating the power consumption let me decide to stop the project.

A clock isn’t only a conversation piece It has to be a reliable time indicator 
for 24/7

A lot of talk of unusual Nixie's recently. A few years ago I acquired a small

weighing scales of some sort. 4 GN-35 AH "upside down" numeric tubes, plus one 
GF-37 A which displays fractions - 1/8.1/4, 3/8, 1/2,5/8, 3/4 & 7/8. If any 
collector is interested, I would be happy to give them away (if you pay 
carriage), as I realistically don't think would use them. Let me know, David.

Hi Nicholas,

 

Am I right the material of the red coating is on base of collodion (cellulose

Pedro, I use Acetone every day as a chemist...of all the solvents you can use, 
it's pretty innocuous (your body actually synthesizes small amounts 
normally)...just use it in a well ventilated area. Likewise, isopropyl alcohol 
may help you with the stubborn coatings also and is safe to use in a well 
ventilated area. If you still have some tubes with paint that won't come off, 
we can then talk about the solvents that are less friendly:-)

 

Best of luck!

Thank you for your idea, Nick. I will try it this weekend. Previously i used a

required manual cleaning. And another issue that different 
manufacturers/factories used different paint and it did not worked on some of 
tubes - the pain was not even softened. Also acetone is very toxic so i'd like 
to find a more "healthy" way to remove the coating.

Anyway i will try your idea. Thanks

Today i finished a little projects that i made from mostly parts that were

can use to test and control tubes. It uses basically a rotary encoder to switch

It also can measure the supply voltage, voltage after anode resistor, and the 
anode resistor itself. When i was planing the project, i was hoping to get 
something near a accurate measurement of it, maybe something like 
170V-175V-180V. But as i checked with a Fluke177 Multimeter, it turned out to 
be accurate to about 1V ! Which is more than good in case of nixies.

Maybe someone can also make use of it, so i thought i share! Schematic,Eagle 
Files, and Arduino-Code are attached! :)

Saw some of these ZM1040 tubes for sale, and I have no idea what they are, 
definitely not Nixies though - any ideas..

 

Hoping you can shed some light. It has 9 pins and is internally silvered - 
possibly a rectifier?

We have had the same situation here in Sweden for the last three months, most 
foreign packages from Russia, China and even the US get stuck in customs but 
pass without problem after a month or so, but strangely some packages fly 
through customs in under a weeks time even though they come from the same 
sender. I know that most of these packages have been stuck abroad and actually 
not in Sweden, so it is the country of origin where they have been stuck most 
of the time, I had to check this thoroughly as I got incorrect information from 
some of the senders.

I don't think Pb-210 (being a decay product of Rn-222) will ever produce Rn. 
Perhaps the best bet (and still very unfeasible) is Radium Ra-226 which decays 
directly into Rn-222 via alpha decay with a half life of 1.6 kyears. (That's 
how the first emission spectrum of Rn was obtained.) That said, you would need 
quite a bit of Ra-226 to keep enough Rn in your tube, as half of Rn will decay 
in less than 4 days. 

 

Best,

Damir

I understand that with a half-life of 3.8 days, getting a discharge tube of any 
appreciable size full of it would be problematic to put it mildly. But is it 
possible to closely mimic its spectrum and thus make a "simulated" radon tube?

The best neon bender I know is Bill Buth. b...@neonstreet.com.  He can fix you 
right up.

His Etsy shop: https://www.etsy.com/shop/BillieBoi

He will stay in the tube if boro glass is used.  Bill can do that.

Kr is totally boring.

Xe you'll probably want filled to a high enough pressure that it snakes around 
in the tube.  Bill knows all this stuff too.

I'd fix you up but inconveniently, someone stole my neon plant several years 
ago and I haven't been able to replace it.

Thomas,

That is the standard end-view Burroughs Nixie tube. The two extra pins are for 
activating the mercury giver, I believe.

The module appears to be European in origin. We don't have capacitors like that 
in the USA, and the TI chips have a European font on their labels.

The shaft sticking out appears to turn a rotary PC board switch through a miter 
gear. The switch looks like it's wired to select one of the ten cathodes. 
Perhaps it allows the user to set a counter trigger value.

To my knowledge getter is only working to oxidizing gasses as oxygen fluor and 
chlorine and other oxidizing gases. Anyhow the oxidizing properties are 
essential.

All metals are typical reducing elements.

Can you tell me the diameter of the display (not the sisze of the square print)?

 

Because it is so scarse, I think it’s rather military than civil.

Hi
I want to share this display, because its awesome!
I picked up a very special panaplex on ebay. It has a Burroughs-Logo on the PCB 
so i guess it was made / sold by burroughs. Sadly all the prints on the PCB 
were not any useful to find something about this display.
I will try to figure all pins out and then create a driving circuit. 

1.) It has two 3-digit 7-Segment panaplex on it, those are multiplexed because 
all cathodes are in common, anodes are different. It also has an up and down 
arrow by the digits. 
2.) It has the words TO and FR. Whats really interesting here is, that the 
parts of the letters are controlled individually, so the O is basically a 
4-segment display. 
3.) It has 4 multiplexed bargraphs on it, they either start in the middle, or 
on the outside, or can be used both way (did not figured this out yet)

So...what could be the use of this display? 

I guess the "TO/FR" could be TO and FROM ? The digits could be speed, weight, 
distance or something else? 

I don't really have an idea what the bargraphs are for...direction... maybe 
position?..

Notice the red and gold connector on the pcb (no its not a potentiometer), it 
is a little locking connector (screwlock like bnc) with gold pins on it.


Any info would be great, but i don't have much hope...

Although nothing should surprise me by now about the insanity of the
American school system, this one touches a nerve. A kid - a young teenager -
made a clock of his own design, took it to school, and found himself in
police custody accused of making a fake terrorist bomb - a "movie bomb".
Maybe it wouldn't have happened if he'd used nixies instead of 7 segment
displays, as then the morons at his school might have asked him what it was
instead of instantly recognizing it as a deadly bomb like the ones they've
seen in Hollywood movies. Way to go, teachers, for discouraging him from
ever doing anything creative like that again.

Hi All!

 

I am trying to decide whether I should build a power supply for my Polyatron 
clock with a simple transformer, rectifier and smoothing capacitor for the 
-160V and -450V that I need or if I should use some Tayloredge 1363/1364 
modules in series. Using the Tayloredge 1363/1364 in series means that I'll 
have to use separate transformer windings for each module as they are 
non-isolated switchers, but apart from that I don't know if I need to take 
anything more into account. I have emailed John but haven't heard back from him 
on the emails that I have sent so I post my question here as I saw that John 
answered other messages on the switchers here.

 

I've included a schematic of the design that I am pondering if it will work or 
if there is anything else that I need to take into account, I am not sure if 
the modules work without problems in series. I need the full power that these 
modules can deliver with the maximum input voltage to be able to drive the 
Polyatrons and Nixies plus driving stages as per the design I have published 
here on the forum. I have enough modules but I don't want to blow them up while 
experimenting with them in series.

I have done a couple (analog) Panel Meter clocks (I know, not nixie - sorry).

 

I was thinking of using an old voltmeter with big meter for a single needle 
clock, but don't think it will be very good for a 'clock'.

 

Searching the webz, I can't find what I am looking for.

 

Does anyone know of an old meter which has 3 meters in it? (As big as possible)
