[neonixie-l] Ceramic Driver ICs

[SWISSNIXIE - Jonathan F.]

Hi Folks, 

For an unique and special project i'm looking for ceramic parts. I've 
already found myself a micro-controller in ceramic and some other ic's as 
well.

It would be nice if i could use also a ceramic nixie driver like the 74141 
or 7441.

Does any one here has them and would like to sell 2-3 pcs?

Thanks!

While I am on this subject, I figured it might not hurt to ask if 
anyone here in our group might have a few

fully functioning 6844A tubes available for sale.   Thanks.  -Chuck

Re: [neonixie-l] Re: Bad batch of Burroughs 6844A nixies

A few weeks ago I bought (2) NOS, NIB National NL-6844A nixies from an 
ebay seller.

When those arrived they got tested and both work perfectly.    -Chuck

@Greg. They are all NOS NIB.

 

@Chuck. I like the domed tube too, but gave up ever trying to find any 
that worked. Like you, I am always more impressed with the National Electronics 
version of whatever Burroughs produced.

They also get sputtered cathode material on the tiny 
ceramic separator washers in the cathode stack which eventually cause

multiple cathodes to glow when only a single cathode is 
grounded.   After the first ten years of operation in my 6844A clock, I recently

swapped out a tube that started having digits 7 and 8 
on together.  Moved that to a location in the clock where only digits 0 through 
5 are used.  - Chuck

Paul - Do any of your failed NOS units have a black or 
silvery coating inside the glass ? I'm hoping that is caused by sputtering, and 
not simple aging.

circumstances. But when the cathodes are still visible, I dont understand why 
they have no glow. I doubt they would be selectively plated with another metal, 
which completely sputtered away, leaving them unable to glow.

 

I have a bag of dead 
nixies, mostly 5031/6844,  took 2 out, and microwaved them for 2 seconds. Got a 
brilliant crimson glow. One of them shows some cathodes working, so now I have 
to go back thru the bag to make sure I find the totally dead ones, or at least 
the ones that have glowing only on the bondwires, and nuke them in the 
microwave oven. I have other boxes for dying nixies, and so-so nixies, so I'm 
really surprised anything in the "body-bag" of dead ones actually glowed. 
Unless perhaps the zap from the microwave oven did something to the internal 
metal.

 

I have some more 
experimenting to do.

Does anyone know of a source where I can get aluminum honeycomb mesh?
There are loads of vendors on Ali selling aluminum mesh but so far I 
haven't been able to find one with a honeycomb pattern.
Thanks in advance.

Re: [neonixie-l] CRT clock kit instructions

['Grahame' via neonixie-l]

Alex

Have a look at my designs if you have not seen them. They are all open 
source and open design. I sell kits from minimal parts up to a full kit. 
I sell fractional kits, so for example, I am working with someone who 
wants to interface a RaspPi so he is only interested in my deflection 
amplifier and HT PSU boards. If you want to develop your own HT PSU then 
I sell the custom wound flyback transformer by itself as well... I don't 
sell and disappear ... I remain to  resolve any problems.

The CPU is STC, a Chinese 8051. The supplied firmware is

I am thinking of building an emulator of the rotary encoder to
change the shape of the display and prevent burning the CRT. Other
ideas are welcome.

All I needed was a PSU to test CRTs :) but I am open to attempt
improvements.

The HV part uses a transformer of unknown specifications. All the rest is
common design. Also the analog driver setup is inspired from other open
hardware scope clocks. I wonder if we have some Chinese speaking members
that could contact the seller to investigate the possibilities of further
development or more kits. Writing in plain English language had no effect
(I got again all the documentation files, no text).

Nick and Alex I sent you the files privately from another email account.
