That sounds really very cool. Any size, within reason that anyone would 
want, and much less expensive than Rodan CD47's. Engrave your own, if 
you're good at that sort of thing, or have it done somewhere. Multi 
colored LED's would also be cool. And just to make sure that the clock

I pondered that awhile back, but I remember my first-ever digital clock I 
built used those same displays (along with stepper relays, 
kachunk..kachunk..), and the stacked sheets would reflect and scatter light 
from the previous numerals. It got progressively worse at the rearmost 
numeral. It was obvious why these displays died-out as nixies became 
plentiful.

Thin, anti-glare glass that is etched might do the trick, but I dont have 
the tools to do that.

BTW, I literally abandoned that relay clock because the relay contacts were 
worn and uncleanable. No regrets.

You could use the modern version of the old edge-lit displays.  A stack
of plex sheets engraved with the numbers and edge-lit with LEDs.  That
would be even more authentic because the numbers would approach and
recede as they change values, just like in a real Nixie.

I'd love to see Dalibor release something that large but pretty.  The CD47 
is butt ugly.  It's like it was a 30mm tube stretched out and poorly 
proportioned.
$2000-2500 per tube is just insanity, doubt the seller will have many 
takers.  

Let's go Dalibor flood the market with something better and let the market 
set the price.

replace them in the future or stock up on spares).

Just my 2 cents :)

[neonixie-l] Re: HV control chips

[gregebert]

I quick-glanced the HV5812 datasheet, and it's a push-pull driver, meaning 
that it drives-out approx 0 volts to turn the tube on, and 80V to turn the 
tube off. Even though the anode supply is significantly higher than the 80V 
rating of the HV5812 device, it's OK to do this because any leakage thru 
the nixie tube is clamped to around 80V by the ESD circuitry in the HV5812. 
As long as the tube's extinguishing voltage is greater  than 
(Anode_supply_voltage - Driver_high_voltage), this clever driver trick will 
work nicely.

This is not the same situation with open-drain (aka open-collector) 
outputs, which have no clamps for positive voltage. Theoretically a tube 
could 'leak' a small current and drive the pin above it's rated limit. Not 
usually a problem for bipolar devices, but it will destroy a MOS device, 
which is why I dont recommend exceeding the datasheet parameters.

[neonixie-l] Re: HV control chips

[gregebert]

That's the driver topology I use, except I omit the zener diode (good idea, 
though, for NMOS) and the base resistor because I dont see a hazard without 
them. If there is a power-on transient that occurs when the HV supply is 
energized (very unlikely, because the HV DC filter cap would need to be 
missing/open) , it would be a positive voltage-spike and the worst it could 
do is cause the driver NPN to turn-on briefly. More-likely, any leakage 
from collector-to-base would bleed-away thru the ESD network on the driving 
logic; the charge would be very small, perhaps negligible, because it would 
be whatever leaked from the collector of the driver NPN to the base (this 
is a reverse-biased junction). Regardless, there still is current-limiting 
because of the emitter resistor.

I'm not aware of any mechanism that would cause a current-spike thru the 
tube at turn-on. When the logic goes to '1', the transistor will turn on 
rapidly, and it may actually saturate because the tube itself requires 
several microseconds to ionize. During this time the base-current will be 
at it's maximum (the target tube current). As the tube ionizes, it's 
current will go thru the transistor and the negative feedback at the 
emitter will gradually reduce the base-current from the logic. There's 
definitely a current-spike from the driving logic as the tube stabilizes, 
but it's only a few mA. You could add a series base-resistor to reduce the 
peak base-current, but if you check the datasheet for the transistor it's 
very likely the max base-current spec is much higher, making the resistor 
unnecessary. Unless I'm really missing something, I dont see where current 
thru the tube will spike at turnon or turnoff.

As far as a current-spike at tube turnon/turnoff, yes there will be some 
Ldi/dt and 1/2LI^2 effects, but they will be small because we're dealing 
with milliamps. For example, if you are switching 5mA off in 10nsec, and 
there is 1uH of wiring inductance, the voltage spike (Ldi/dt) is 0.5 volts. 
[ Imagine if this was a motor controller with a 50 amp load.ouch!... 
but there are circuit techniques to deal with that ].

I concur Luka. However, there will always be someone who wants to collect
rare things at any cost, so best of luck to him/her, I'm sure they'll find
a buyer somewhere...personally, I think nixies should be used for what they
were intended, not stored away in a drawer etc...but that's just my
opinion, nothing more.

With those kinds of prices, it's just a matter of time before Dalibor
flexes his tube making skills and makes an extra large Z568
variant..hopefully!!!

Best to all,

Nick

I pretty much enjoy "collecting" different types of Nixie tubes and 
sometimes spend like 100$ or 150$ per tube, but paying ~2500 euros for a 
Nixie tube is just ridiculous in my honest opinion. I mean, if such amount 
is something you earn easily and you really feel like you "just have to 
have one or more", then I can kinda understand it, but if you have to to 
really spare for quite some times to buy these, you should think about how 
many other things or experiences there are that you could enjoy and enrich 
your life with...at least here in Europe, you can buy a brand new car or 
take a really exotic trip somewhere you'd always wanted to go to. I look at 
this the same way as with people spending tons of money on some rare 
Elvis's clothes or similar "collectibles" and wonder do they still feel it 
was worth it after all the years they own those. Besides, I doubt you can 
be sure these tubes are NOS or that they have been properly stored for all 
those years, so you could be buying something that might malfunction in a 
few years due to gas leaking caused by broken air-seals on the pins and 
similar defects (of course, you could say this for other tubes as well, but 
for them you're paying like 15 times less money so you can pretty much 
replace them in the future or stock up on spares).

Just my 2 cents :)

I've got an answer from him. When asked for price for 4 tubes, he answered 
with 10 000 EUR. 
Well, he really does know how rare and valuable they are.

  I grabbed a couple from AJ's photos back in the Yahoo days. The C-7417 Loran 
controller/display and the CP 748 radiation dose gadget.

  BUT, I really do still want other examples.

   

  I own a many-Nixie time code unit and a Systron Donner time display [larger 
Nixies] that I could photograph, but I want something more military or 
defence-related.

I'd like to see some, too. 

 

Back in the mid to late 80's, the US military put out a joint recruitment 
commercial on TV. It was highlighting the high tech equipment, all the branches 
used, implying that the recruits will get career building tech skills. One of 
the shots was a piece of gear, inside a tank, that clearly used nixie tubes. 
That gave me a chuckle, at the time, since nixies were long obsolete by the 
time, that commercial aired.

 

That commercial has to be floating around somewhere.

Can anyone point to their favourites please?
