Seeing letters in a nixie (curvy) format is un-nerving in some way...
The artwork is described on the artists main website here it seems : 
http://dominicharris.com/simulated-2018/
This appears to essentially be a giant *n* letter word array, but with the 
letters limited to " S I M U L A T E D O"
Quite odd but certainly impressive, if just for how much money must of been 
sunk into it.
I would of just stuck at a 10 letter word myself, but maybe Dalibor had a 
minimum order ;-)

Lovely stuff. There are a lot of tubes involved in the project - if I 
understand the annotations correctly, there are 12 instances with 60 tubes 
and 12 with 10 - that's 840 tubes!
 
Something about the write-up on the website looks a bit strange... It 
claims that the artist fabricated the tubes - did he really go work in 
Dalibor's lab for a few months to learn and make them? Or did he just pay 
Dalibor to do it? In the latter case I think a slightly more accurate 
description is needed...

Unlike most folks here, I do not have any background in electronics nor 
exposure to the electronics perspective of nixies and glowing tubes. 
However, I do go way back with nixies, too. I started as a computer 
software developer in the 1970's and worked on Burroughs systems for years. 
Burroughs machines had neon and nixies as part of their design. So through 
the lifespan of neon, nixies, numitrons, LEDs, LCD, VFD, TFT, etc, I have 
been interested in the glowing things and the progression of the 
technologies though this brief history of a few decades. 
I really didn't think a lot about nixies between about 1980-2010. In the 
early 2000's I thought it would be nice if I taught myself a bit about 
electronic. I figured it would be useful  or at least quench a curiosity.  
I started building B.E.A.M. toys and then progressed to doing on-the-chip 
gadgets the leveraged these amazing PIC and Atmel microcontrollers. I was 
really excited about the features these little chips had. And I started to 
experiment more and more learning ever so little about actual electronics, 
but a lot about these little ucontrollers. A few years later, I was talking 
with a friend about some of the self-teaching I was doing building tiny low 
voltage toys and robots. He is an LED display freak and he asked me if I 
knew about these things called dekatrons. I hadn't heard of them. So I 
looked into it and discovered that there was crossover into the old nixie 
work that I lived in decades ago. I couldn't believe (still cannot) that 
you can get such wonderful old display tubes and make them do amazing 
things like you all do here. I was hooked right there and then and got a 
kit from threeneurons and haven't looked back since (except to look back 
and buy more nixie stock and more projects).

6844 saga continues.
"in the past I too quest for picoseconds  "conan the barbarian"  or 
was it westdave?
i used 6 of the very pretty bullet shaped B6844 nos nib, i ran them at specs 
with a clock that ran with a 10mhz rubinium oscillator that could have been out 
of a US ICBM sold to china as dismantled parts and sold back to california 
,they run hot to the touch and are stable to about 10 to the negitive 11th   
.0and elevan zeros  ,and i was running against a EM608A GPS mod putting out a 
nice clean one second from space.(to see if they would drift apart and how long 
it took to error)
the B6844's lasted one month and then they were as black as coal,even the hours 
rated in the specs are low ,so i pulled them and plugged in the radioactive 
nixie with the (long number )and changed the very neon color, for a sharp, 
pink/orange, these will last forever.

6844A saga
  
  

  Paul Andrews : Mar 23 08:06AM -0700   
 

Hi all,
 
I recently bought some 6844A tubes of ebay - I fancied making a four tube 
clock with round top-view tubes. In my head I had assumed that these would 
be doped with mercury, but they aren't. However, before I found that out I 
bought four Raytheon JAN 6844A tubes and 2 Burroughs 6844A tubes - I 
figured if I changed my mind and wanted to make a six tube clock, I might 
as well have the extra tubes lying around. Another assumption: They would 
have the same mechanical specs, but they actually look very different - I 
prefer the look of the Burroughs tubes.
 
All of them are NOS.
 
So, I tested them and the Raytheon tubes are fine. One had Cathode 
poisoning (NOS? It was in the original box!). That was easily fixed with 
some over current and it was fascinating to see that work - this is the 
first time I have had to do that.
 
The Burroughs tubes are quite a different story. On one of them, half the 
digits don't light up, but the leads to the digits do! I have posted some 
pictures below. On the other one, none of the digits light up - only the 
leads. Well, I'm going to put this down to experience - I am probably not 
going to build a clock with tubes that aren't doped with mercury - but I 
would like opinions as to what might be going on with the Burroughs tubes. 
Note that the behavior is independent of the actual anode current - other 
than how brightly they glow!
 
This one shows just the lead lighting up:

This shows the digit 3 and the lead lighting up:

Thanks for the recommendations everyone - I actually reached out to 
Pete 
shortly after the BD discontinuation news, and ordered his Spectrum 18 kit, 
PIR and Case last week. He has been an absolute pleasure to work with - 
responsive, accommodated special requests and provided a first-rate 
experience overall during my first order with him.
 
I ended up losing a tube to gas leakage on my BlueDream, and I attribute it 
to the rigid cup-style pin holders that stress the gas seal (1992/02 date 
code tube failed after 10 months of service, even leaving it in the same 
location). I am afraid to move the tubes around the BD, and Pete's design 
solves the pin stress issues (also like the PIR shutoff feature).

It's a pity. It's still my favorite IN-18 clock because it is compact 
and I like the proportions (the tubes are on the axis of the board).
I was also secretly hoping that the black'n'wood would become available again.
 
Maybe things have changed since.
Also, I don't know what others expect from someone who sells nixie DIY clock 
kits as a hobby, but on the rare occasions when I had a question or a problem 
with Claus' and Dieter's clocks, I always received good advice on how to repair 
it myself.
 
The board of the Blue dream isn't expensive enough to be sent back (especially 
from the USA) and spend hours on a repair.
 
I never had problems with gas leaks with the nixies I bought from Dieter with 
the clocks.
One set is from '92 as well.

I'll echo the perceived lack of service tooI've repaired two blue 
dream
clocks for people as no support was offered..
 
Pete's Spectrum 18 is a great clock for a very good price.

Thanks for the recommendations everyone - I actually reached out to 
Pete 
shortly after the BD discontinuation news, and ordered his Spectrum 18 kit, 
PIR and Case last week. He has been an absolute pleasure to work with - 
responsive, accommodated special requests and provided a first-rate 
experience overall during my first order with him.
 
I ended up losing a tube to gas leakage on my BlueDream, and I attribute it 
to the rigid cup-style pin holders that stress the gas seal (1992/02 date 
code tube failed after 10 months of service, even leaving it in the same 
location). I am afraid to move the tubes around the BD, and Pete's design 
solves the pin stress issues (also like the PIR shutoff feature).

It's a pity. It's still my favorite IN-18 clock because it is compact 
and I like the proportions (the tubes are on the axis of the board).
I was also secretly hoping that the black'n'wood would become available again.
 
Maybe things have changed since.
Also, I don't know what others expect from someone who sells nixie DIY clock 
kits as a hobby, but on the rare occasions when I had a question or a problem 
with Claus' and Dieter's clocks, I always received good advice on how to repair 
it myself.
 
The board of the Blue dream isn't expensive enough to be sent back (especially 
from the USA) and spend hours on a repair.
 
I never had problems with gas leaks with the nixies I bought from Dieter with 
the clocks.
One set is from '92 as well.

nice and clean two digit clock made from a clause urbach 
,http://www.nixieclocks.de, two digit clock kit from long in the past with the 
brand new R/Z568  from Dalibor Farny.and a kundo glass dome clock ,

(VINTAGE KUNDO ELECTRONIC GLASS DOME PENDULUM CLOCK MADE IN GERMANY WORKS 
GREAT.)there is always one of these type clocks for parts,at a resonable price. 
Do  I like these tubes ? why ,yes i do, they plug into the old style sockets 
,and are priced right and have a great #4 if you were wondering if you should 
have a set ,you could not do better ,i used a 8.66k anode resistor at 170 Vdc

[neonixie-l] make a clock go to jail

['westdave' via neonixie-l]

 wait a gosh darn?minute,look at that photo i sent of the "bomb clock"?
#1)it is a plug in 115vac with a 9volt battery back up
?#2)there are no batterys in the case so he had to open it to plug it in (no 
big battery pack?no big boom)
#3)it is a factory board in fact two of them( one the clock board and the 
second is the switch board)
?and no one uses wire like that for interconecting boards and the led display 
but the factory
#4)once again you would have to open the case to set it
conclution(he built nothing) ,he took a factory clock( sunbeam,ge emerson?) and 
put it in a cool case ,moved the led display to the front and did not even move 
the set switches
or drill a hole for the power cord , and now he is going to meet the president 
of the united states (WTF)



where you will be flown by air force one from irving texas ,rushed from the 
airport?to the white house in washington D.C.and maybe then we will take off 
the hand cuffs!

[neonixie-l] KLOK K7 broken from corrosive rot

['westdave' via neonixie-l]

I have a IN-18 clock in a aluminum case called Klok K7 (a wonderful case)
however after many years of service 4 out of the 6 tubes just went out (not 
blacked out but still clear) I disassembled the clock to see what's up? answer 
is! corrosion ,like some one had been dropping water in it for ten years, 
somehow the aluminum of the case reacted with the solder to become cottage 
cheese,print board,
after cleaning off the gunk, through out both boards ,upper and lower,including 
some sanding of printed ,board copper and the soldering of some lost copper 
with tiny wire,point to point,still 4 out of 6 no light ,time to pull out the 
meter ,
so I had 170 volts still working ,and I had the 5 volts needed for the 
IC's,tested near the hv resistors no voltage
on inspecting the three anodes there were no more thru holes to the other side 
of the board (eaten away forever)I sanded the copper print and added point to 
point wire and got the anodes back,now the 6 tubes lit and as a  precaution 
changed the 74141 IC's(they must have had a hard time ,replaced)but still a bit 
wonkey,i pulled the IN-18 tubes to look under neath , a whole bunch more 
cottage cheese rot,running pin to pin among the sockets (that's conductive crap 
on glass going pin to pin)(,more sanding,cleaning of the tubes them 
selfs,tested ,passed, test OK,clock restored, last bit, i sprayed plastic on 
both boards )covering the pins and sockets with tape before i sprayed them with 
plastic, in hopes it will arest the crud,and it will not form again
 so after many years this came out of no where (and if you also have a K7 you 
might check to see if it is OK or rotting before your eyes)
thanx the davester westdave

person. That it one technology that actually can be made in your garage. 
Don't have to tool up and develop the skill set required (vast

what kind of gas has a green color ?


i once had a cadmium neon laser,it would not fire a beam but the tube did glow
the most fantastic color of green close to aquamarine
so try neon cadmium gas mix


http://www.visualphotos.com/image/1x6037042/emission_spectrum_of_cadmium


http://www.lamptech.co.uk/Spec%20Sheets/Osram%20Spectral%20Cd.htm


 Helium-Cadmium (HeCd) 325 nm are three examples. These lasers have 
particularly narrow oscillation linewidths of less than 3 GHz (0.5 
picometers),[4] making them candidates for use influorescence suppressed Raman 
spectroscopy.

  If you'd like other colors you can have white with Xenon filled tubes, 
and also orange and green with some of the other gas regulator tubes.   Ira.

  Well Dalibor, now you have me wondering. Last time I actually worked 
with any VR tubes was years ago, and I swear that one of them had a 
greenish color to it. It may have been due to a 'mix" of more than one 
gas. I'm going to fire up some of the VR tubes that I have and see if I 
do remember correctly or not. Stay tuned for more.Ira.

  Hi, from what I saw on internet, the krypton is more white-blue
colour.. The green colour gas is something what I would really like to
try in nixies, especially if it is inert gas.. There are some photos
of discharge in krypton, but who knows how accurate the photo is:

  If you want green, I suggest green glass and Xenon gas (numerous spectral 
lines in the green region), and perhaps a bit of Helium. I would avoid Neon 
because it's mostly yellow/orange/red spectra.
  
 

  
  John Smith  Jan 10 03:29PM -0500   
 
  The really small neon bulbs are sometimes stained to add color.  On neon
signage sometimes gas mixes are used and also various metal halides are
mixed with the gasses.  The large high voltage vacuum tube rectifiers
usually have mercury when ionized neutralizes the space charge.  The
voltage regulator tube have neon and argon mostly.

  According to Wiki, Krypton should emit a violetish colour. I guess also 
UV.
So maybe you have seen a krypton discharge lamp with an Uranium glass
mantle. The green colour will be due to fluorescence evoked by  the UV-light
that excites the uranium atoms to send off green light.
 
 
 
@Dalibor:
 
Beware of uranium glass it is extreme expensive, however, may be in your
country it might still be made (Bohemia?).

Even with higher current, the glow was barely affected. It's so dim that it

[neonixie-l] total nixie weirdness ,i approve

[westdave]

http://www.youtube.com/watch?v=9aYYE3F4zM0


this is a friend of mine(living at the edge where there are no last names) 
,when he started this he knew very little about stepper switches and how they 
work ..now ,he has wrote the book,i assure you there are no diodes in this 
"thing" and please note the pulsar for the stepper is a Mercury switch and a 
motor to tilt it.
is he an inch from maddness? i don't think so ! watch his 31 videos and be 
amazed, welcome to boonsburg,yes it is all true!

just a thought about opto isolaton the old days you could find black soda 
straws with a lamp on one end and some kind of sensor * at the other end * a 
pin diode * a phototransistor* or a cds resistor (light active resistor) they 
also would use this type of a rig on old wah wah pedels and volume pedels( no 
noise,like with a pot)maybe a design using resistance? i can not make the jump 
to how many hours something can hold off 2000 volts,would it depend on the 
diodes?

Slightly OT - 2kV voltage isolation? [4 Updates]
  
 Slightly OT - 2kV voltage isolation?
  
  Grahame Marsh  Nov 30 06:13PM   
 
  I'm looking to pass a, i2c bidirectional data signal between two systems 
that have about 2kV voltage difference between their respective 
"grounds".  I can find several device on, say, Mouser's website but I'm 
getting lost with all the insulation terms.  There is a variety of test 
voltage conditions like "Vrms for 1 minute" and "galvantic isolation in 
kV".  These voltages are typically 4 - 6kV. But I also find "Maximum 
working insulation VIORM 566 voltage" - so does this mean a normal 
working voltage difference? And so well less than 2kV.
 
Sorry, but I need an idiot's (that's me) guide to what isolation voltage 
I should be looking for to isolate these systems that live 2kV apart?  I 
know there are solutions that use multiple optoisolators and drivers but 
I was looking for a single chip solution.  Any helpers please?
 
(The application is between a microcontroller and the cathode circuit of 
a CRT so it is almost on topic.)
 
Grahame

 Yet another event counter in ePay
  
  GastonP  Jul 02 07:55PM -0700   
 
  Hey guys... just saw a beautiful one:
 
http://www.ebay.com/itm/Vintage-Hunter-Dekatron-Nixie-event-counter-/161058286086
 
It is really in very nice state. No doubt the innards got some maintenance 
(the tube that can be seen from the back slot vents is shiny, not something 
to expect after around 50 years life).
Rest assured that if I were not a continent away the title of this thread 
would be "Look what I got on ePay" instead :)
 
Nothing to do with this sale, seller or anything.
 
Cheers
   Gaston

All good stuff, but the critical thing about UV is its wavelength - 
anywhere from 10nm to 400nm.
 
Below 300nm, dangerous to people - above that is mainly UV-A which is not 
too bad - its like cholesterol - there is bad (LDL or all UV *except* UV-A) 
and "not so bad" (HDL or UV-A) :)


westdave
 where did I come up with that stuff about the atomic bombs and a glass 
windshields
in his book" surely you're joking Mr feynman"
Richard feynman said, that's where he was sitting during the first atomic blast 
,in a jeep watching from behind the windshield to block out the UV
(yea ,it would be much more fun to just make things up. but sometimes I can 
back them up!)

I wonder if it is the right UV light for a mineral lamp (compared to that laser 
pen he carry's)
surround it with rocks and see if there is any greenium inside them
anyway the ticket here is to reflect the light off the rocks and see if there 
is any absorbed and then reflected light of vairous colors, just like a crt tube
wear sun glasses to avoid snowblindness
in case of abomb hide behind glass this will help with the uv but not the blast

 866 Mercury Vapor Rectifier as Novelty Lamp

  
  threeneurons  May 29 02:33AM -0700   
 
  I went to the TRW swap meet on Saturday, and picked up a 866 mercury 
vapor 
rectifier. The thing has a 2.5V 5 amp filament. Good thing I had this large 
transformer in my stash with a 2.1V tap. Needed less than 50V to light it 
up, and get the emission up to get more than 50mA thru. Tube is rated for 
250mA max average.By sticking a 2200uf cap across the the tube, plate to 
cathode, it turns into a relax oscillator. Tube drop is only 11V. I never 
had a relax osc, that couldn't bite me. Even though this rectifier was 
intended for use in power supplies capable of delivering thousands of 
volts, this circuit is quite harmless, until the glass breaks:

You read my mind - I would have thought that this was a real (not

causing corneal damage, cataracts & macular degeneration. 
 
I'd really be very careful with this, especially if there are children 
around - there are reasons that these things were run inside cabinets...

However, since then I've built several of Pete's very nice kits and did the 
kit part ordering for some of the UK & European customers. Pete's clocks 
are far more functional and use modern components... I also have a 
GPS-disciplined Jeff Thomas/Pete Hand clock that SWMBO absolutely loves...
 
The world has demonstrably moved on...

 GeekKlok and FLW up for grabs
  
  Raymond Weisling  Dec 04 07:09PM -0800   
 
  I feel it is only reasonable that I defend myself from the poison pens 
that 
gathered.
 
The history is that my company went bankrupt, or was forced to close its 
doors. These nixie product were not al all the main business We did new 
product design engineering for a US-client that made health care signal 
systems and they were my client (before I formed a corporation) from 1990 
to 1999, with one assistant working with me. In 1999 things with them were 
looking better and I had some money to invest in forming a limited 
liability corporation here in Indonesia. I then hired four engineers and we 
kept this client in California happy until 2005 or 2006. Then they were 
bought out by Tyco International, and for about a year we kept running but 
suddenly they gave us notice that they were moving everything and merging 
with Simplex Time Recorder in Massachusetts, where they already had 80+ 
engineers. My 4-man team meant nothing to their bottom line.
 
At that point we began working with a local company that made traffic 
lights and took them on as a client. After about five months of work, they 
were unable to pay close to $5000 in invoices, and we had to stop. I had to 
take care of my staff during this time of promises from the other company, 
but when it was clear that they were unable to pay (they were cheated out 
of $40,000), my staff quit one by one, because I was forced to pay their 
salaries late. This is where the whole thing unraveled. Several times I 
tried to recover and eek out a living with the nixie products, but with too 
little capital to invest and sudden expenses from some health emergencies, 
we were in a spiral. Debts piled up. I'm paying interest of 30-40% oer year 
on some debts, which makes it very hard to climb out of a slimy hole. 
 
I'd love to pay everyone back and I never had any intention to cheat or 
defraud anyone ever. (Someone said hundreds of customers who didn't get 
products, but the total is probably about 50-70.)
 
As for loss of sales data and no loss of engineering materials, the 
engineering materials were on two old Macintosh computers, one of which is 
still working at age 12. The sales stuff was in a PC Windows machine that 
got hit by lightning surge, in a different part of the house, quite removed 
from the other. We had the old Zetalink office in a separate garage, and 
that is where I put kits tohether, did assembly of units and packed orders 
for shipping. That's where both telephone and electric power lines entered 
the premises. The engineering files in my Mac were in a second floor 
bedroom converted to an office, quite separated, and protected with a good 
surge protector. (The adjoining room had some non-nixie things and that's 
the room where a whole wall collapsed in the May 2006 earthquake, more ton 
a ton of debris was all over the contents. That earthquake was only 5.9 
magnitude, but killed about 6000 people (on my own Dwelling Unpreparedness 
Index (DUI) it was the third worst worldwide earthquake since 1945).
 
I just want to see that these products continue on and can help pay off 
some of my local debts where interest is so high. A hospital project coming 
up may provide enough funds for refunds to people, but the banking details 
for it have been delayed for six months or more. I just don't want to cheat 
anyone, never did intentionally, and certainly have no interest in doing it 
again. Bad Karma.
 
I hope that the bitter people can release their poison. They harbor ill 
feelings, so they live with that poison. Learn to forgive, very powerful 
medicine. I am very sorry for injuring so many through the mess I went 
through.
 
Very Best WishesRay

 What's the worst neon display you ever had?

that would be the nib nos B 6844a nixie tube ,destroyed 6 in 30 days 
this is like the B5092 but has a bullet shape to them
they have no mercury in them, i ran them with the wrong resistor(6.8k instead 
of 15k from spec. )for one month and now all six went from clear to all 
black,(added a10 k to all tubes ,so now it is 16.2k)
thing was,the tubes would not light ,or had numbers poisoned(from being in a 
box on the shelf so long,)that i needed a smaller resistance just to get them 
to cycle,"to get 6 tubes with all the numbers working,some times is a task,and 
the tubes need to be" cooked" to use them,once i had the 6 working i forgot to 
change the resistor ,and did not dream it would be half what it should have 
been.

 Iv-11 vfd
  
  Spencer  Jun 15 07:53PM -0700   
 
  So I have been playing around with IV-11 VFDs and looking for some input. 
For the filaments, I have tried using a MC34063 to generate the 1.25 volts 
needed for it and then tried using a 62 ohm 3 watt resistor with 4 tubes in 
series.
 
The resistor generates a lot of heat so I am thinking of using a 5 watt. I 
liked the MC34063 but it made it more complex than I think it needs to IMO. 
 
Just wondering what everyone has used for the filament.
  
 

  
  Michel  Jun 15 08:43PM -0700   
 
  Did you wire the tubes in series or only the resistor with the tubes 
parallel? The current through the filament is only 100mA which means the 62 
ohm resistor only dissipates 0.62W if the 4 filaments are in series. If you 
wired them in parallel (400mA) and only use 1 series resistor the 
dissipated heat in the resistor would be 9.92W and the voltage across the 
resistor would be 24V which doesn't sounds right. So maybe you are doing 
something different all together.
 
A drawing of your circuit would be helpful.
 
Michel

I'm bringing up a board for powering VFDs including IV-11 and IV-17.  For 
filament power, I was determined to power them with true AC, but put off by 
the high cost, large size, and difficulty of designing an efficient high 
frequency transformer.  A line powered transformer was also out of the 
question.
 
So I use a 5V powered complementary MOS half-bridge AC coupled to the 
filament, with the other end of the filament tied to +5V.  That way, the 
average voltage of the filament is always +5V to create a negative grid 
bias when the grid is at 0V.  The driven end of the filament wiggles 
between +2.5 and +7.5V, so never violates the negative bias of the grid.  
That the average DC voltage across the filament is always +5V also ensures 
an even brightness distribution over the anodes.
 
To drive the half bridge, I have a pulse steering circuit using a flip-flop 
and a pair of NOR gates.  This can be driven with a 20-25kHz PWM from a 
micro.  Alternately, if the micro is smart enough to generate a bipolar PWM 
with dead-time, the pulse steering logic may be omitted and the MOS 
transistors driven directly, through a TC4428A complementary MOS gate 
driver IC.  I stuck that in there, because it also permits the V+ for the 
filament power circuit to be powered from a higher voltage than +5V if 
necessary, while still allowing the MOS devices to be controlled by a 
3.3-5V micro.
 
Finally, there is also a place for a 555 timer IC on board, in case the PWM 
is desired to be made entirely on board, without needing the micro.
 
Ultimately, with a micro smart enough to generate the full gate drive 
signals, my circuit consists of only a TC4428A, a little SOIC-8 
complementary MOSFET IC, and a 150uF Panasonic FM or FR series electrolytic 
coupling cap.  You could probably even omit the gate driver IC for the 
IV-11.  And this circuit avoids the pitfalls of DC filament drive.
 
I was also worried about electromigration shortening the filament life if 
driven by DC.  But I suspect that at the relatively low temperature of the 
filament, this may not be a concern.  Maybe some tube experts here can 
comment on this.
 
Well, there I've spilled my secret filament circuit.  Maybe someone will go 
and patent it now and sue me to prevent me from using it!  Such is the 
world.
 
P.S.  I

The cat is still glowing fine!

at what voltage is  the cat glowing? not 170 vdc?

 Z5680M - dark grid
  
  kay486  Jun 06 11:22AM -0700   
 
  Hi there, i just bought one Z5680M tube pretty cheap and now im waiting 
for 
it to arrive. The thing is that it has dark corners on the anode grid. So 
im bit worried that it might not function. Does anybody know what could be 
the problem, and if it affects the tubes function? (see the picture)
  
 

  
  Jeff Thomas  Jun 06 11:31AM -0700   
 
  It appears to have a few hours on it, although it should be an easy task 
to 
remove any oxide buildup (cathode poisoning) from the digits.
They're scarce these days, so handle with care :)
 
Regards, Jeff

  I have several with similar darkening, and they are just fine. But, like 
Jeff says, it most likely has a few hours on it. It may be fine and then 
again, it may not! No way to tell until you get your hands on it. I can 
tell you this, most of the 5680's I have that have this sort of darkening 
did require some "rejuvenation" on my part.

 Arduino-based FLW
  
  Matthew  Jun 06 04:13PM -0700   
 
  Many thanks again for the help on this. Somewhat improbably, I now have a 
working LED-based prototype on the breadboard - it includes the modes of 
the original and a few new ones too. I have multiplexed it for now - to 
save space and bits at least - I started out the hard way but then 
discovered the timer interrupt of the Arduino chip which makes it much 
easier. But my display is fairly well abstracted from the rest of the code 
so if it turns out I want to direct drive, it's not rocket science to 
change it.
 
So my circuit is fairly simple - In each multiplex cycle, the Arduino 
writes out to 3 74HC595 shift registers:
 
* 1 controls the anodes of the 14 segment displays (just one at a time in 
this case) - these go through 2N3904 transistors, since the total draw of 
one character is more than the register can handle
 
* The other two control the segments; for now I'm using resistors such that 
the 74HC595 can sink the current so they are connected directly to the 
cathodes.
 
Now thinking about moving up to the tubes. Very simplistically, I'm seeing 
the eg B7971 as a bigger version of the common-anode LEDs I'm using - just 
requiring a higher voltage and current, so needing to be driven through 
appropriate transistors. I'm sure it can't be *that* simple though - can 
anyone broadly summarise what other things I need to consider?
  
 

  
  Adam Jacobs  Jun 06 05:12PM -0700   
 
  Another stepping stone you might consider (although it is completely 
backwards) would be a 16-segment VFD based FLW.
I know that I personally would be very interested in such a device, 
given the significantly higher VFD availability than B7971. VFD's are 
common cathode and are voltage regulated rather than current regulated 
as nixies&LED's are.
 
As for how to drive Nixies versus common anode LED's.. They're pretty 
similar. Just as you say: Higher voltage & higher current. In both cases 
you are sinking current through a voltage limiting resistor. Your 
current limiting resistor calculations will be different, your supply 
voltage will be different, very likely your driving IC (or transistors) 
will be different. They easy NPN transistor that is commonly used is the 
MPSA42. Other than that, there are tons of different options for driving 
the nixies ranging from the antiquated 74141 to the supertex parts to 
all kinds of solutions.

i never saw a nixie tube fail in so short a time;or go totally black from 
sputtering for that matter,nixie's can be run for 10 years with no visible 
discoloration ,i have done so,any others?

 Nixie life specs
  
  "JohnK"  Apr 25 05:56PM +0930   
 
  I have noticed many discussions about the lifetime specifications of 
Nixies. I haven't noticed anyone quoting the manufacturer definition of 
lifetime -  but I may have missed it. So, read on ...
 
"Electronic Counting circuits techniques devices ", Mullard Limited, October 
1967. approx. 220 pages. Many circuits.
Various authors and sources.
There seem to be about eight of these books available through ABE ranging $20 
to $60. Bound to be others at the usual places too.
 
The approx 13 page chapter on numerical indicator tubes is based on material 
supplied by B. Butler of the Mullard Industrial Electronics division.
 
 
I have included some of the text below rather than attach scans [if allowed],
John Kaesehagen
Australia.
 
 
 
>From the 'numerical indicator tubes' chapter I quote this [via OCR] :-
"The normal figures quoted in published data for the life of a numerical
 
indicator tube are 5000 hours with a continuous display of one character,
 
and 30 000 hours when sequentially changing the display from one digit
 
to the next every 100 hours or less. The end of life for the above figures is
 
taken to be the time when any character is unable to be covered completely,
 
although several more thousand hours would probably have to elapse
 
before the character became completely indecipherable."
 
 
 
The above is contained within this section:-
 
 
 
"  LIFE PERFORMANCE
 
The expected life performance of a numerical indicator tube depends to
 
a greal extent on the length of time the discharge is investing any particular
 
cathode. With any gas-discharge device, the cathode is subjected to constant
 
ion bombardment which removes material from the cathode and
 
deposits it elsewhere in the tube. This "sputtering" process, as it is known,
 
is, in fact, put to good use in many cold cathode gasfllled tubes during
 
processing. The cathode surlaces are cleaned in this manner and any
 
sputter material thrown on the glass walls of the envelope effectively seals
 
in any foreign matter that may affect the performance of the tube during
 
its life. In a numerical indicator tube, however, although a clean cathode
 
is desirable, sputter material on the envelope would impair the visibility
 
of the display. Some sputtering is unavoidable, but since the rate of
 
sputter is proportional to the peak current of the tube, it can be contained
 
within limits.
 
If one cathode is continually glowing, sputter material from that
 
cathode is deposited on other cathode surfaces in close proximity.
 
Although the legibility of the glowing cathode is not affected to a great
 
extent, the cathodes on which the sputter is deposited are affected. In
 
fact, the work function of the metal of the adjacent cathodes alters in
 
such a way that it requires a higher current to completely cover the
 
cathode and if this current is not available, the cathode appears patchy.
 
This imposes a minimum permitted current level on the tube. It is possible
 
that complete erosion of the cathode may result from bombardment,
 
but this is unusual.
 
If the discharge is cycled betweerr characters fairly regularly, this gives
 
a very much improved life figure since each cathode, although receiving
 
some sputter material, is subjected to the cleansing action of bombardment.
 
In this case, the higher the current, the more effective the cleansing.
 
The viewing area of the envelope is protected from sputter material by
 
the use of a shield, or mesh, which is usually connected to the anode.
 
>From the foregoing it is evident that the end of life of a numerical
 
indicator tube is not abrupt, but takes the form of a gradual deterioration
 
of a character. This is convenient, because it enables a tube which is
 
showing signs of deterioration to be replaced before it fails completely.
 
The normal figures quoted in published data for the life of a numerical
 
indicator tube are 5000 hours with a continuous display of one character,
 
and 30 000 hours when sequentially changing the display from one digit
 
to the next every 100 hours or less. The end of life for the above figures is
 
taken to be the time when any character is unable to be covered completely,
 
although several more thousand hours would probably have to

Davester tales of the glowing clock

I bought a CRT clock off of ebay,because that's what I collect,I have try ed to 
get a nixie clocks , when ever they are made ,I have a David Forbes cathode 
corner CRT clock running 24/7 for many years now ,and I collected a nixie 
wristwatch before there all gone,and a cathode corner 6 digit clock with 6 x B 
-5092,three kinds of cosmodog nixie clocks ,the stuff that makes history,
i bought a CRT clock a few years back from Howard 
Constantine,Oscilloscopeclocknixiecrt.com, howc...@hotmail.com,it was made on a 
piece of PC perf board (a look I love ,hand made)and the plastic case got 
roughed up by the post office,but I love it just the same,a few years later , 
the clock failed,I emailed Howard, he was more that great, I turned in the old 
one for useable parts , and traded up to the new CRT clock... this one is even 
cooler, the last one had hands and ran analogue style .The new CRT clock runs 
both digital and hands ,face,style and toggles back and forth,awesome!

next up ,let the healing begin,for those who were scammed,this is the way to 
go, TODAY, time to let the past nixie crimes be forgot ,there is this instead
i just bought the Jeff Thomas  gps flw clock

jtho...@amug.org

The GPS FLW circuit board (assembled)  $109
 
 Laser Cut transparent acrylic enclosure kit$40
   
 Haicom HI-204III 20ch serial GPS receiver $60

total$219 delivered,no tubes, At last a use for them!

this kit is sexy, the case design is fantastic ,and see thru ,lots of fun to 
watch, it makes words i never heard of,but so what,it's suppose to be fun,
its safe to come out now and pull those B7971 out of the boxes and drawers
,don't sell them now that they are over $100 each,buy this clock plug them in 
you are done.

poor lost lad! ray's bank is in Pasadena,he took a lot  of money from a lot of 
people with a wink and a smile ,he never said he need help(just cash please) 
,he just fleaced any one who was dumb enough to send money and not once did i 
think that trade in another country would cost me ,with no recourse,
i have had some trade problems in the soviet realm,but no one but ray has ever 
walked away,from the table with out giving me the time of day!
can't i find a place in my heart to forgive him?NO!
even when you look at both sides of the coin?...NO!
and because ray lives in java 
i will wish him a KRAKATOA christmas(don't get any on ya)

 Merry Christmas
  
  fixitsan  Dec 24 05:01AM -0800   
 
  I would just like to wish all group members a Happy Christmas
 
It is 10 years ago that I began my first experiments with nixie tubes,
when I decided that I wanted to make a nixie clock for my father's
60th birthday present. So, beginning in November I ordered tubes, some
PICs, downloaded Microchip's MPLAB for the first time and taught
myself assembly language for PICs. It was a steep learning curve
considering the 10 week deadline, but I couldn't afford a higher level
language so battled on.
 
Then my interest continued with an invite from Ray Weisling to join
the first nixie group, NEONIXIE-L on Yahoo, when he saw me selling
clock number 2 on eBay, which I made in order to pay for both clocks.
 
It is nice to see so many of those members are also here, and with you
there is also a huge number of new people with an interest in nixies.
It is nice to know that so many people share an interest with
yourself !
 
Although I built the first clock alone, it is true to say that I would
not have improved my skills or opened my mind to some very interesting
ideas had it not been for my membership of that group, and the
support, the nagging, challenges and humour shared among all members
there, and now here.
 
I seem to have taken those ideas sideways into developing the
Smartsocket concept, originally for neon based tubes and now for the
IV-17 vfd tubes which I first began experimenting with in 2007. (it
has been a slow project !)
 
Merry Christmas and the best of the season to you all and your
families

  Merry Christmas to all on the list also!  I am happy to have found it as a
newcomer this year, and really appreciate everyone taking time to answer
basic questions.
 
I decided at the last minute to build a very modest single tube numitron
IV-9 clock for my brother-in-law for Christmas from scratch.  It was the
first major (for me anyways) electronics project that I breadboarded myself
with an arduino and then transferred the design over to perfboard and wrote
the arduino code myself (with help from other web sources of course), and
then burned my own ATMega328p chip.  I used a DS1307 chip for the RTC with
a battery backup I desoldered off an old motherboard.  The tube displays
blinks a 4 digit time and has the option to display the date, and set both
from the board.  I spent a lot of time struggling with the code and adding
new features, and had to stop myself from adding a piezo speaker in the
fear of running out of time.  It's not the prettiest thing to look at, but
it works!  I know he will appreciate the effort as he loves gifts people
have taken the time to make.
 
Anyways, this marks my exciting entry into the world of tubes (not counting
some an earlier nixie clock kit that I fell in love with).   I'm sure I'll
be harassing the list with many questions in the new year, so prepare
yourselves!
 
Best,
Dylan

Z568M 50mm ($400 each)use oversize socket ($$)  IN18 40mm($40  )use pcb&mill 
pins socket . ZM1040 30mm($80)same socket as b5092
so the IN18 has more bang per buck, but the gas mix is near violet when you 
pump them
hard,i think that an orange filter (dipped orange in french lacquer)would 
improve there color,any one try this?or orange plastic filter in front of them 
or orange color jell (used in stage lighting)made into a tube and slipped over 
the nixie.

this is the one you need 180 vdc @25ma power supply with the MAX1771 IC reg,  
never a better one.

try to keep away from the 555 designs and seek better efficiencies
like the max1771

although it will not run on 5 volts like the taylor  type
(1364 - SmartNixie HVPS-H (Horizontal   Module)
  Includes  8mm Dia 330uF   
  EEU-FC1C331 input capacitor
  1.8V to 16V input, 150V to 200V adjustable
   output 
  4W @ 5V input = 23mA @ 180V
  8W @ 12V input = 45mA @180V
  0.95" x 0.95" x 0.35")

 FLW clock case  
 Power supply that provides over an amp instead of max 50mA?
  
  Imbanon  Nov 08 05:18PM -0800   
 
  Hey hey!
Finally, all the parts arrived for my power supply!
http://www.ledsales.com.au/kits/nixie_supply.pdf
But I have a little problem..
I have built it and wanted to test it before I connect it to anything.
As I do not have a limited current supply, or any kind of lab power
supply, I used my home made old PC power supply of 12 volts 15A, and
connected in series a 10ohm 0.5W resistor to limit the input current
to 1.2A max.
Now I do know that the wattage of that resistor is way too low, but I
guess it is better than anything for limiting the input current.
 
So I breadboarded the circuit, and apparently it does provide variable
voltage as it should. Then I shorted it with my amp meter to check the
max output current (I expected around 50mA tops).
To my big surprise, I measured 1.2A on the output! Also the limiting
10ohm resistor burned out in a matter of seconds as expected, but the
mystery remains.. How the heck could I get 1.2A out?
 
I double checked the circuit, I don't think there is a mistake..
So can anyone advise me on this? Is there a problem with the circuit,
or did I really make the impossible 100% efficient step up circuit xD
I think there might be a problem with the measuring procedure -
shorting the circuit without a load (I don't have a resistor of proper
wattage)
 
Thanks a lot!

Easy, it flows from the input, through the inductor and diode, and out the 
output.  You don't get any boost that way,
but Iout = Iin, basically.

hi guys westdaves here ,still glowing after "three neurons "story of me pinning 
the geiger counter at the TRW (is true)
but about the nimo tube ,i have a few of them and the original power suply but 
hey ,what kind of IC or transistor do you need to control them 
by COSMOS, TTL, or microcomputer (para lax,A dumbo,avr ,pic)
2500 vdc seems hot,but they are little CRT's  
are there opto isolators at 2500 vdc(this would be a good place to start!)
so yea nimos ?

under rated but oversize,just my two cents but the nixie tube that is often 
overlooked,are very lovely in size and use,not all that hard to get ,
the big round tube B6091(.8 inch,18mm) fits into the same socket as the 
zm1040(30mm),B5092(.6 inch 12mm)
i like to mix them with the B5092 ,like HOURS (1)B6091 (1)B5092 MINS, (1)B6091 
(1)B5092,SECONDS, (1)B6091 (1)B5092

 2.5kV power supplier for Nimo tube
  
  marcin  Nov 06 01:55AM -0800   
 
  Hi All,
 
Recently I acquired couple of those Nimo tubes. And now of course I
would like to test them.
Nimo needs 2.5kV DC @ 35 uA of anode voltage.
How to generate this kind of voltage? The current is almost nothing.
Would it be possible to use 10+ stages of voltage multiplier starting
from a regular switching Nixie power supplier? Or rather should I look
into designing something myself? Probably as a fly-back transformer?
I would be grateful for any suggestions, solutions.
 
Cheers,
Marcin

  I know somebody, who has an original NIMO kit, including PS. I will ask 
him
to contact you

  CW multiplier is the obvious (and cheap) way... especially at that low
current.
 
I have a few of these too, but have yet to light one up... so many
things to do, so little time ;-(

  I'm thinking your B7971x8 display support landline caller ID functions. 
Just wanted to put that out there as an interesting function, especially for a 
display with support for 7+ numbers/characters. Caller ID and call waiting 
caller ID is part of the ADSI spec, it's basically a Bell 202 (simplex) modem 
burst of data.
 
http://en.wikipedia.org/wiki/Analog_Display_Services_Interface
 
http://telecom-info.telcordia.com/site-cgi/ido/docs.cgi?ID=SEARCH&DOCUMENT=FR-12&;

There's probably a chip out there that grabs it (through an optocoupler or 
optoisolator) and delivers TTL level ASCII out the back end.
 
I'd like a longer than 8 tube device, personally, but 8 would be great, 
especially if the data scrolled.

i got one and it had cathode poisoning after sitting for how many
years unlit ?
i took it down to 1k at 5wa...@115 vac and every thing got warm to hot
but the funk would not blast away and is still there after many
hours(when it is hot you must keep an eye on it ) ,what's
next ,bombarding?a lower value resistor ??(hot hot)

yes you got it , you can not hurt any thing by clicking up and down
the increment scales , so go mad see what .o1 will do?.05, .1 ,1, 10,
100 /then let me know and i will code in about a dozen clocks

with 53 adjustments it must be in there some where did you get the

here it is option #50 software time correction -99.99to+99.99  default
-3.03  so click away
