Re: [neonixie-l] NIMO

One can only image what one of those would auction for.

While it's impressive that 64 characters can be displayed, I'm 99.99% 
certain those characters are static. In other words, it's not a generic 
64-character display that shows arbitrary messages. In order to do that, 
you would need a deflection/scanning system like a regular CRT. And since 
it's a round tube, there will be fewer visible characters on the top and 
bottom lines (datasheet says up to 5 lines / 8 chars per line).

I really feel sorry for IEE; they tried so hard to make this device work, 
but were just too late to market. The MAN-2 5x7 dot-matrix LED was on the 
market not much later than this ad was published.

 Most of the NIMO tubes I've seen, which isn't very many, have 31 in 
 the part number (P31 phosphor), though I have seen two with '92' in 
 the 
 part number that have a yellowish tint mixed with the normal green. I 
 wasn't able to find any phosphor designated P92.

I'm not sure what is going on in this site, I think the "seller" is just 
posting the tubes to show off instead of them being for sale, but there is 
a blue colored one pictured? The description seems to only mention green 
with numbers, green with symbols, and orange, so maybe the blue is just

 Most of the NIMO tubes I've seen, which isn't very many, have 31 in the
 part number (P31 phosphor), though I have seen two with '92' in the part
 number that have a yellowish tint mixed with the normal green. I wasn't
 able to find any phosphor designated P92.

 The only problem is that these will work loose from vibration and
 thermal cycling. Use bayonet based bulbs instead. Trust me.

Re: [neonixie-l] NIMO

[gregebert]

I dont think IEE got their NIMO tubes into volume production, and I've 
never seen any photos of a real product using them. There is a photo of 
some kind of gizmo in the IEE sales literature, but that was probably a 
mockup. It's unfortunate that all the engineering effort and talent that 
went into their creation didn't get the recognition it deserved. Had they 
appeared 20 years earlier, perhaps nixie tubes would have been the rarities 
instead of NIMOs.

Well, none of my green ones have the 'right' number on them either, so
maybe they were all pre-production?

Re: [neonixie-l] NIMO

[gregebert]

Are there any markings, part numbers, etc that indicate this tube has a 
different phosphor ? I suspect it could be an ultra-rare engineering sample.

Most of the NIMO tubes I've seen, which isn't very many, have 31 in the 
part number (P31 phosphor), though I have seen two with '92' in the part 
number that have a yellowish tint mixed with the normal green. I wasn't 
able to find any phosphor designated P92.

Re: [neonixie-l] NIMO

[Nicholas Stock]

I'm going to sell this Red NIMO tube. It's apparently unused (no phosphor
burn at all) and all the digits work as you can see in the video. I'll be
honest and upfront with everyone here, I'm looking for serious offers and
will keep in mind that listing it on the bay incurs fees etc, so if
interested, please send me an offer.

All the other used green NIMOs sold.

Best,

Nick

Re: [neonixie-l] NIMO Patents

[gregebert]

I watched an Ebay auction about 10 years ago for a lot of 4 XM1000 tubes; 
in the final seconds it went for over 1600 USD. I like their flat-screen. 
Too bad they are so rare.

Eric - What is the difference between XM1000 and XM2000 ?

The only I know is that they won a sue against Telefunken who fringed some of 
their patents with the development of the XM2000. Telefunken had to destroy all 
the produced tubes, however some came at the black market. I own one.

She's got a few Tubes and only has 1 in use and not enough to build a clock.
Maybe she's willing to part with one "for science".

There is a tube called the TX-19A, which is similar to the MTX-90, but it has a 
green phosphor like that in a magic eye. Some went up on eBay recently, but it 
looks like they’re sold out now.

Re: [neonixie-l] NIMO

[gregebert]

Hard to say. 10,000 hours is 30 years worth of display time at 1 
hour-per-day which is probably reasonable. The problem is what were the 
assumptions, or test conditions, that led to that lifetime ? And was it the 
phosphor that burned-out, or the filaments ? We really dont know. I 
speculated that for equipment that is used for an 8-hour shift, 5 days per 
week, you would have a service life of 5 years (reasonable), and roughly 
1250 power-cycles if the equipment is turned-off at the end of the day. 
However, without knowing the failure mechanism, it's a guess on how one 
should operate the tubes.

I thought about getting an NOS vacuum tube, and power-cycle the filaments 
to the point-of-failure; not the same exact filament, but it's a useful 
datapoint. OK, run 2 tubesone with inrush current limiting, and the 
other without. Sure as  wont be doing that with a NIMO 
tube...even the mere *thought* of that makes me cringe.

Greg, if they turn out to last like IN18's (datasheet says only >5000 hrs),
then you should be good! :)

Re: [neonixie-l] NIMO

A PIR is a must. Datasheet for the BA-P31 says 10,000 hrs at 100
Foot-lambert (FL). Is there any reason to think that these should age
differently from a regular CRT?

Re: [neonixie-l] NIMO

[gregebert]

now the BIG question..how long will the NIMO tubes last ?? I've done a 
limited amount of runtime on mine, less than 50 hours, and I can already 
see very faint phosphor burn with a UV lamp. My anode current is around 
30ua (varies by digit, but averaging around 30ua which is the datasheet 
spec). I also wonder how long the filaments will last (each tube has two 
parallel filaments), either from power-cycling or total runtime. I have 
inrush current-limiting on the filaments so they dont get stressed as much, 
per recommendations on how radio/TV stations prolong the life of their 
expensive transmitter tubes.

I have a PIR sensor to shutoff the HV after a programmable time (currently 
100 seconds), and another programmable delay to shutoff the filaments. The 
filament timeout is the one I'm not sure how to optimize; I was thinking of 
running up to 26 hours so I could do multiple activations per day without 
cycling the filaments. I do have a front-panel switch to override the PIR 
sensor so that the display will stay off, and consequently force the 
filaments to time-out.

I dont have enough NIMO tubes to experiment with and determine the best 
timeout to maximize lifespan. I'm hoping it will end-up like the Voyager 
spacecraft, which were overdesigned and have outlasted the wildest 
expectations of how long they will function.

Re: [neonixie-l] NIMO

[jörg]

The TH-19A is pretty interesting but unobtainium.
So I have switched to the green neon indicators, which I've ordered some 
time ago at aliexpress.
Same type as gregebert use, I guess. I've mounted them a bit too far from 
the center.
The nimos are dimmed based on a LDR, so I have to pwm the indicator bulbs, 
to sync to the nimo brightness.

I didn't buy them. I noticed they were listed a couple days ago. Didn't

Re: [neonixie-l] NIMO

[gregebert]

I bought from aliexpress several years ago. Had to buy 1000, so I split-up 
and resold to neonixie members to offset my cost.
Other colors are available; blue would be cool.

 You could ask Fran Blanche
 She's got a few Tubes and only has 1 in use and not enough to build 
 a clock.
 Maybe she's willing to part with one "for science".
 Tell her you're building a 6-tube clock and she's your only hope...

I'm using green NE-2 bulbs. Internal phosphor is white; glows green when 
energized. The lifetime isn't as long as gas-only bulbs, so be sure to 
mount on a plug-in card.

Re: [neonixie-l] NIMO

[jörg]

Is there a green-glow flathead indicator tube available? 
Size like the MTX-90 Thyratron or smaller. I would like to use them as 
colons for separating H:M:S.

Re: [neonixie-l] NIMO

[jörg]

Yes, this is the clock from Roger.
And he is the guy, who helped me out with one tube, becaue one of mine was 
outgassed.
Again, thank you very much selling me one.
His is the leftmost one in the video, it is a BA -P31 (blueish-green), 
whereas mine are 6000-92-0006 (yellow-green). 
And the font is slightly diffent to the others.

And, @all please take it not too serious, the clock is for sure not the 
worlds first 6 tube nimo clock, as it is not the most dangerous one...

 You could ask Fran Blanche
 She's got a few Tubes and only has 1 in use and not enough to build a 
 clock.
 Maybe she's willing to part with one "for science".
 Tell her you're building a 6-tube clock and she's your only hope...

Nice to see one more 6 digit Nimo clock!

There's at least one other 6 digit Nimo clock that was shown on Youtube 
about a year ago: https://www.youtube.com/watch?v=JA1oeqavMg8=3s

Just a small update,
I've made a short video regarding the build of my 6 tube nimo clock.
And thank's a lot to astroschmidt to sell me one of his nimo's to complete 
my clock.
You sure will see his nimo in the video.

 Jorg - Regarding the dead tube, have you compared the filament 
 resistance of the bad tube to the others ?

 NIMO tubes have 2 parallel filaments, so if one is open, the 
 resistance will be TWICE the value of a good tube.
 I think the cold resistance is around 3 ohms.

 If 1 filament is out, you can still get 5 numerals to work.

 I would be surprised if both filaments are burned-out, unless 
 someone put way too much voltage on it, or the tube is cracked around 
 the 
 pins.

 If the filaments are OK, power-up the tube and make sure you get 
 around 180mA of current.
 Then try varying the voltage between the filament and the logic 
 driving the grids. If a grid is about 6 V more positive than the 
 filament, 
 you should get a numeral to turn on.

 Hi Martin,

here´s another YouTube video where I unbox the Ebay-auction package (if you 
haven´t already found it):
https://youtu.be/7Mprac_anEA

If I find the time I will scan the documents that were included in the 
Ebay-auction and share them here.
.
The five tube mounting bracket is ATM under use in the prototype.
I will take photos of the bracket and the bezel, when I am ready with the 
clock enclosure.

 Martin, you are right.
 I've checked the getter flash and it is gone. Only a white shadow left.
 So, sadly, the tube has sucked air and is cracked somewhere at the pins.
 Unfortunately, I don't have a plasma ball.

 I've made some experiments with multiplexing the tubes.

Would it be possible for you to share the circuit diagrams that you got in 
the box with the tubes, I haven't seen some of them, just the datasheet.

Also, can you share some photos of the mechanical pieces in the package, 
like photos of the five tube mounting bracket and of the power supply (saw 
some photos in the video)?

 What does the getter flash look like, like a mirror or is it gone 
 completely, or has it gone white?

 I have seen a few Nixies where the Anode wire has come lose at a 
 welding spot, can you see if something similar has happened to your Nimo 
 with any of the wires or the Anode connection - if so you might smack it 
 gently against your palm to see if the wire reconnects enough for it to 
 work again?

 NIMO tubes have 2 parallel filaments, so if one is open, the resistance 
 will be TWICE the value of a good tube.
 I think the cold resistance is around 3 ohms.

 If 1 filament is out, you can still get 5 numerals to work.

Re: [neonixie-l] NIMO

[Robert G. Schaffrath]

Had the same thing with a NOS IN-12B though they do not compare to a NIMO 
outgassing. I was refunded the cost of the IN-12B and they are readily 
replaceable. But those metal to glass bonds are not always tenacious. 
Outgassing has been an issue with vacuum tubes since the dawn of their 
existence. Tubes were still popular when I was young in the 60's and 70's 
and I recall my father and grandfather removing tubes occasionally with a 
milky white top from their TV's (grandfather had a Dumont!).

 Jorg - Regarding the dead tube, have you compared the filament 
 resistance of the bad tube to the others ?

 NIMO tubes have 2 parallel filaments, so if one is open, the resistance 
 will be TWICE the value of a good tube.
 I think the cold resistance is around 3 ohms.

 If 1 filament is out, you can still get 5 numerals to work.

 I would be surprised if both filaments are burned-out, unless someone 
 put way too much voltage on it, or the tube is cracked around the pins.

 If the filaments are OK, power-up the tube and make sure you get around 
 180mA of current.
 Then try varying the voltage between the filament and the logic driving 
 the grids. If a grid is about 6 V more positive than the filament, you 
 should get a numeral to turn on.

Martin, you are right.
I've checked the getter flash and it is gone. Only a white shadow left.
So, sadly, the tube has sucked air and is cracked somewhere at the pins.
Unfortunately, I don't have a plasma ball.

Re: [neonixie-l] NIMO

[Dekatron42]

Have you got a Plasma ball to hold it to? If air has entered in you might 
see a very faint blueish glow if you turn off the surrounding light.

What does the getter flash look like, like a mirror or is it gone 
completely, or has it gone white?

I have seen a few Nixies where the Anode wire has come lose at a welding 
spot, can you see if something similar has happened to your Nimo with any 
of the wires or the Anode connection - if so you might smack it gently 
against your palm to see if the wire reconnects enough for it to work again?

Re: [neonixie-l] NIMO

[jörg]

Hi Gregebert, yes, I've checked the tube several times. The cold resistance 
is about 2,1 ohm, which is identical to the other tubes.
Just swapped the tube with a running one on the same driver board. Sadly, 
no function at all. Under a microscope, no crack is visible.

I've made a short video to show the difference between a neon-nixie and a 
nimo crt-tube and a neodym magnet (very small one.)

[Robert G. Schaffrath]

"Those nimo look like tiny CRTs!  If anyone can make them it’s Dalibor!"

Talk about a niche market. Not only are they infinitely more complex to 
construct than a Nixie tube, the market for them would be even smaller than 
for his Nixie tubes.

I had commented on the short YouTube video that it would have been 
interesting if the manufacturer has made NIMO's available in other colors 
besides green. Red especially for critical indicators. Consistent anode 
voltages might have been problematic as different phosphors have different 
requirements. I have still seen some tiny 1" round CRT's up for sale from 
time to time. Might have an easier time getting and using those with custom 
logic to draw numerals.

Re: [neonixie-l] NIMO

[gregebert]

Jorg - Regarding the dead tube, have you compared the filament resistance 
of the bad tube to the others ?

NIMO tubes have 2 parallel filaments, so if one is open, the resistance 
will be TWICE the value of a good tube.
I think the cold resistance is around 3 ohms.

If 1 filament is out, you can still get 5 numerals to work.

I would be surprised if both filaments are burned-out, unless someone put 
way too much voltage on it, or the tube is cracked around the pins.

If the filaments are OK, power-up the tube and make sure you get around 
180mA of current.
Then try varying the voltage between the filament and the logic driving the 
grids. If a grid is about 6 V more positive than the filament, you should 
get a numeral to turn on.

Re: [neonixie-l] NIMO

[gregebert]

Filaments are about 1.1V; you want to limit the current to 200mA max. 180mA 
is quite good and will prolong the filament lifetime.
The anode is typically 1850V, at 30uA.

The anode current determines the brightness, which is the 'wear-and-tear' 
on the phosphor. So, keeping the anode current on the lower side so that 
the tube is still readable is essential.

Lastly, the 10 individual grids control the numbers displayed. When a grid 
is negative with respect to the filament, say -3.5V or more negative, that 
character is extinguished.
When the grid is positive with respect to the filament, that digit will be 
displayed. The brightness of the digit can be controlled by adjusting the 
anode voltage, or by adjusting how positive the grid is relative to the 
filament.

In my NIMO clock, I have a DAC to set the offset voltage between the 
filaments and the grid logic. The grids are driven from CMOS shift 
registers on a 10V supply. The HV supply is also software-programmable.

Just curious, what's the filament voltage?  27VDC?  And what's the HV?

Nice name and very nice look. I mainly use Elecrow for my PCBs as they have

might try OSH-Park just for this PCB!

It looked like 2 or 2.5mm to me.

Re: [neonixie-l] NIMO

@Martin: regarding your question of longer life on higher anode voltage:
No, that's not what telefunken means. They wrote on behalf of multiplexing, 
in my opinion, a bit confusing.
In other words: at multiplexing with higher beam current, the effective 
current (like rms) is nearly the same as in using no multiplexing (with 
lower anode voltage).

If you like, take a look at: 
http://www.cathodecorner.com/nixiedata/nimo808p06.jpg

And, yes that's one idea, which I've in mind, why to use 6 separate 
filament drivers.
I will try out multiplexing, too.

Re: [neonixie-l] NIMO

[gregebert]

I remember watching the XM1000 auction on Ebay a few years ago; I believe a 
set of 4 went from 400 USD to over 2000 in the last few seconds. Their 
rectangular shape had a better appearance I thought.

The driver circuit is quite simple and inexpensive: eight  MC14094 will 
control 6 tubes and will cost about 4 USD (50 cents each). The annoyance is 
the series grid resistor, you need 60, but SMT devices are very cheap, so 
another 1 USD for those.

I use socket pins, with a 3D-printed collar for the tube socket. The anode 
clip is also 3D printed.

Re: [neonixie-l] NIMO

[Dekatron42]

I did look through the XM1000 datasheet the other day (the Telefunken copy 
of the NIMO that had to be scrapped due to the patent battle between IEE 
and Telefunken, which IEE won) and found one interesting thing about 
running these displays multiplexed (just as the NIMO datasheet says that 
you can multiplex the displays) but they don't mention the decreased effect 
on the phosphor screen when doing so, like Telefunken says.

[image: XM1000-multiplex.JPG]

With Google translate you get:

"



*To display multi-digit numbers, the number display tubes assigned to the 
individual digits of the number can also be operated, for example, in time 
division multiplexing at a high repetition frequency.The fear that the 
lifespan of the luminescent layer will be shortened due to the higher 
high-voltage value necessary for pulse operation is unjustified: at higher 
high voltages, the electrons penetrate deeper into the luminescent layer. 
Therefore, a larger proportion of the material of the luminescent layer is 
stimulated to glow.With the same beam current, this means reduced specific 
stress on the luminescent material.*"

So multiplexing these might be a way to go to get a simpler circuit even if 
you have to raise the HV-voltage some to get the same illumination, and if 
what Telefunken writes is correct you'll get longer (?) life if you raise 
the HV-voltage as the stress on the phosphor screen is less - any comments 
on this?

When looking through the XM1000 datasheet on my computer I also found a 
piece of paper that I had scanned for some old small transformers that I 
bought many years ago for other vacuum tube related experiments and they 
will do just fine in testing the XM1000 heaters as they have the 
possibility to select output voltages from 1V to 30V in 1V steps by 
jumpering the outputs correctly, or with two transformers with their 
primaries in series you'll get 0.5V to 15V in 0.5V steps. Now I'll just 
have to find a suitable CCFL-inverter to start some experimenting.

Re: [neonixie-l] NIMO

[jörg]

I'm playing with the idea to use a TPS22810 Load Switch and a non fet royer 
for each tube.
I've ordered samples from TI.
The idea to use a current regulated supply was my first try. I've build one 
with a LMZ22003, which is a real interesting chip, because it's output 
voltage can be as low as 0,8V with inrush current limiting.
www.ti.com/lit/ds/symlink/lmz22003.pdf
But i've dropped it, because of the biasing, gregbert mentioned, and my 
fear of a broken circuit, which could probably pass 12V directly to the 
filament.
Anyway, I'm using the LMZ for driving and regulating the CCFL inverter 
supply, which works flawless.

Re: [neonixie-l] NIMO

[gregebert]

I gave that idea a lot of thought, but I decided against it for 2 reasons:

#1 It will waste a fair amount of energy. There were several methods I 
analyzed using the power sources I had available in the design, and this 
was the closest to a perfect solution.

#2 Using the center-tapped transformer made the best sense because it 
simplified the bias circuit, and using AC resulted in "averaging" that 
circumvents brightness variation seen in VFDs with a DC filament supply.

I would have used a current regulated supply for the filament (well, six of 
them in your case), which will also automatically give a nice soft start-up, 
and allow you to easily monitor the filament by monitoring its voltage.

Re: [neonixie-l] NIMO

[gregebert]

After some experimenting, I ended-up using 5.1 ohms for a single resistor. 
I could have used 2 resistors, one on each side, to maintain DC balance but 
instead I chose to use a single resistor so I could have my FPGA monitor 
the filament status, along with it's associated fuse and resistor. Each 
filament has it's own 250mA fuse for protection (this is a 6-tube NIMO 
clock). It wasn't necessary it was to go to that extreme, and it burned-up 
a lot of FPGA pins, but this is a project/experiment where I really wanted 
to go overboard with the instrumentation and self-checking. DC-balance 
really isn't necessary because everything averages-out over time, and I 
just adjust the DC offset (with a DAC under software control).

Regarding the filament, it's actually 2 parallel-connected filaments inside 
the tube. So when 1 of them blows, only half of the digits will work.

My original intention was that I would monitor the anode-current for all 6 
tubes, and I could detect a partial filament burnout by checking for 
lower-than-expected current. Software could isolate the failing tube, then 
shut down the clock. Unfortunately there is a source of noise in the op-amp 
summer circuit I use that gives me erratic current readings. Eventually 
I'll figure out what's wrong.

Re: [neonixie-l] NIMO

[Dekatron42]

Well, I can answer my last question on my own, didn't think correctly there 
- of course you don't short these resistors as that would result in 2.5V 
across the heaters.

The reason I asked was because I thought you perhaps had two sets of series 
resistors, one left in the circuit at all times and one that was shorted 
after some time.

So you are using something like a 6.8 Ohm series resistor on each side of 
the heater to get these figures?

If you use a series resistor on each side, what effect does that result in 
on the DC-bias, none or something that you have to adjust for?

Do you short these resistors after some time so they are not affecting the

Be careful about the inrush current when energizing the filaments; the cold 
resistance is around 2.8 ohms, whereas hot is around 7 ohms. So, with a 
1.1V supply, your surge-current will be about 400mA unless you use circuit 
tricks to lower it.

I use a series resistor + fuse and drive from a 2.5V transformer; my peak 
current is around 250mA,  and 180mA operating.

Re: [neonixie-l] NIMO

[jörg]

Yes, i agree with grebert.
The filament driving was the most "dangerous", in terms of afraid, part for 
me.
Not the high voltage.
I do not want, in any case, to overload or destroy the filament due to too 
much current.
The 1,1Vrms are crucial, because it affect the lifetime of the tube. 
Thats why I've choosen the royer type of pws and not a linear regulated 
power supply, which was my first idea.

low), and any toxicity of internal materials would be no-worse than a CFL 
bulb (I doubt NIMO tubes have mercury, but they do have phosphorus and 
other things).

Even the high voltage (2kV) isn't harmful due to the low current (30uA per 
tube) as long as small capacitors are used.

By far, the biggest risk is the handling of the tube itself, and making 
sure the circuit never exceeds the ratings of the tube, particularly the 
filament.

Hi Martin,
i did not work on the ghosting issue. I'm waiting for the pcb's.
After that, i will start get rid of that problem.
@paul: yes i know that video. It looks like that the ghosting issue is 
there, too.

Re: [neonixie-l] NIMO

[gregebert]

Martin - I'm using MC14094 CMOS shift-registers to drive the NIMO grids, 
with a 1meg series resistor. The CMOS shift registers are driven from a 
10VDC supply, so the grids are either 0V or +10V. To get proper cutoff, I 
drive the center-tap of the filament transformer from a buffered DAC, so I 
can set the bias via software control.

When the DAC is set to +6.5V, the actual voltage at the grid relative to 
the filament is nominally +3.5V (on) or -6.5V (off). Of course this varies 
due to the AC voltage across the filaments. But it averages over time and 
all characters have the same brightness.

Re: [neonixie-l] NIMO

Hi John,
yes, it is a CCFL inverter salvaged from an old flatbed scanner.
I've tweaked it a little bit to get the positive anode voltage. 
A HV Diode from an old flea zapper and high voltage capacitors.
This one works pretty well, because it is adjustable from 6 to 12 volts, 
which gives me 1600 to 2300 volts.
Schematics attached.

What are you using for a high voltage supply?  Looks like a CCFL inverter?

The filament PWS is tested with ballast-resistors delivering 1,5A. That was 
flawless. But, anyway, it's not tested with 6 Nimos right now.
I've tested your advised filament bias offset. Unfortunatelly no change to

Nice work. If you adjust the DC bias on the filament, you should be able to 
reduce the ghosting and get a sharper image.

My NIMO clock uses a DAC to set the offset, so I can have software adjust 
it.

Have you tested your power supply at full-load ? I had to make a lot of 
adjustments to solve an overheating problem at full load.

The Soviet-era ITS1-A is an even more bizarre tube, but there seem to be 
more of those floating around. I have a 6-digit ITS1-A clock from one of 
the designers here, and a couple of the single-tube demo boards that the 
VTA made a limited run of a few years ago.

Some things that seemed bizarre in the early 60's jump-started whole 
industries - for example, the primitive integrated circuits designed for 
the Apollo space program led to modern IC technology. Display devices had a 
similar explosion of types and designs, but very few of them had much 
impact. Nixies (defunct except for hobbyists), Numitrons (defunct except 
for very few niche applications), VFD, LED and LCD are really the only 
major ones I can think of (and 2 of those are defunct).

It may be that the nimo was designed for applications where the high 
voltage was already available as part of some other component. IEE did sell 
power supplies, but that seemed to be more for evaluation purposes than to 
put into actual production gear. Speaking of odd combinations, I believe 
the type 6977 VFD was designed as a logic level indicator for vacuum-tube 
computers.
