Thanks!
Still have to clean up the edges of the aluminum.  The aluminum is a funny 
story.  We recently tore down an old aluminum screen door and the bottom 
panel was this aluminum.  It was actually two sheets back to back, so the 
sides that where touching where still nice and shiny.  Now that I think of 
it the tubes and aluminum are both from the 70s.

I have another of these built and waiting for the case and 3 more boards I 
might turn into clocks eventually.

I've used an INS1 as a colon in one of my clocks.  They tend to flicker 
sometimes.  I've been running one for a while and it was fine for several 
days.  It flickered occasionally for a few more days and has since 
stabilized.  They look nice so hopefully they just take some time to 
settle.  Let me know how they work for you when you get around to using 
them.

[neonixie-l] Re: IN-28's in real life...

[Tyler Bourne]

Adventures with IN-28s.

I have determined that in this clock the IN-28s are operated in the 
following way:

The anode is connected to half wave rectified 240V AC, the cathode is 
grounded through a 4.7K resistor.
The grid is connected to the control board through a 1M resistor with a 
3.9M pulldown.  I assume the grid voltage is around 160-170V

The original transformer is gone so I will have to make a new one.  This 
isn't too bad since I can make it with a 120V primary.

[Tyler Bourne]

Thanks Dekatron42  didn't know of that list.
Google translate does give me some information but it can still be hard to 
follow since Google translate is not very good with technical documents.

Thanks again Kosbo, the translation makes more sense now.  Too bad the old 
datasheet doesn't list which pins are for which gate lol.  I'll have to 
power up the board and probe it.

So a К134ЛБ1 would be 2 2input NAND gates and 2 2input NOR 
gates.  https://eandc.ru/catalog/detail.php?ID=6671

Thanks for all the help.

I've gotten back to work on fixing this clock but I'm stuck on a chip.

It's a 134РМ1.  I found a sort of datasheet here:  
https://eandc.ru/pdf/mikroskhema/k134rm1.pdf

Translation doesn't really help much with this one though, something about 
storage elements.

Can any of our Russian speakers help me out?

While I don't think Google will discontinue Drive any time soon it is a 
good idea to have a few backups.  We are currently using 2 of 15 GB so it 
should be some time before we outgrow it.  When that time cones we can 
either find someone who will host it for free or pay Google to get more 
space.

In the mean time I'll go through the files and categorize them all and see 
if I can plan out a consistent folder structure.  Then I can sort it all 
out.

A community owned and operated site would be the only way to ensure ongoing

survive.

Organizing the files in the file section here first would help though and 
make an eventual move over to a database site easier.

Re: [neonixie-l] Re: IN-28's in real life...

[Tyler Bourne]

I haven't gone over the power supply yet.  It looks like the main transformer 
is missing.  If I can figure out what voltages it needs I can find/make a 
replacement. The wires from the socket to the transformer look incredibly thin. 
With all digits lit it must draw around 150-200 watts if each one draws around 
50W.  The draw would depend on the time but I'm not sure how those thin wires 
handled it.  It might have some sort of multiplexing going on so that all 
segments are not lit at once.

[neonixie-l] Re: IN-28's in real life...

[Tyler Bourne]

The clock has arrived!  It's Huge!  
It seems like the clock was in the process of being stripped for parts when 
it was saved.  The tens of hours board was covered in nasty flux, probably 
the plumbing kind.  I've cleaned it up and put it back in.
I've created a schematic for the display board and will start working on a 
replacement.  While the display boards are all the same the control boards 
attached to the back of them are all different depending on which digits 
are needed.  I can tell this is a 12 hour clock since the tens of hours 
digit can't form a 2, interestingly most for the tubes on that board have 
never been used.
Since the display boards and the controller boards are separate I can 
replicate the display board the way it is.  I will create a replacement 
control board for my clock and will also create a more modern control board 
for use with the spare display boards I will have. 

The IN-28 is an odd nixie, it runs at a higher voltage and has a control 
grid.  All the groups of control grids are connected to the HV supply 
through a 3.9M resistor and to the chips through a 1M resistor.  I'll have 
to figure out what all these chips are and find a modern equivalent.
If any Russian speaking members of the group can help identifying the chips 
I would be super grateful.

[neonixie-l] Re: IN-28's in real life...

[Tyler Bourne]

I did!
I will reverse engineer it and make a replacement board.  I will order 10 
of them unless anyone else wants to buy(or trade for) some.

In the pictures it looks like there is a board that holds the tubes and a 
driver board on the back.
I will try and make the tube boards as universal as possible so people can 
connect their own drivers.  I might also design a modern driver board as 
well to go with it.

[neonixie-l] Re: Where our Nixie may have come from?

[Tyler Bourne]

Those are some fantastic control consoles.  I would kill for one of those.
I bet a lot of the ones that have been modernized with LED displays had 
Nixies or Mechanical displays originally.

[neonixie-l] Re: Tube database?

[Tyler Bourne]

That site does look pretty nice.  It would be nice for a database to have 
pictures of the tubes.  It can help when trying to identify a tube with the 
markings missing.

[neonixie-l] Re: RZ568M clock kits?

[Tyler Bourne]

Hi Dalibor.

I have a couple thoughts on a kit.

I would lean toward through hole components if possible to improve ease of 
assemble and hackability, this may not be practical though.
Using a socketed Arduino compatible controller would also help with the 
hackability. 


I can't wait to someday see a jumbo nixie for an affordable* price.
*compared to a CD47.

PS.  I actually like the shape of the numbers in the CD47, makes it a bit 
more unique.

[neonixie-l] Re: trading nixies?

[Tyler Bourne]

I have a few misc. Nixies and Numitrons, Got a bunch in a lot and these are 
the odd ones out.
Nixies:
B-7009 x1 - Used in box so UIB I guess?
B5750 x1 - NIB
ZM1000 x1 - NOS
NL8422 x1 - Used
Another like a 8422 but missing it's markings and slightly differently 
built x1 - Used
KS-19944 x1 - Used, Same as 8422, Its definitely used since there is some 
very slight darkening of the glass, still very usable though. (Technically 
in it's original box but the box is nasty)
NL840 x2 - Used (Wang Labs 340-0004)
B-5440A - Used? (Might be NOS) Still on driver board B 200-100-628-A
B-5442A - Used? (Might be NOS) + - symbol tube Still on driver board B 
200-100-627-A
B5031 x2 - Used (Hard to determine, Markings on tubes nearly worn off when 
I got them)
NL5092 x1 -used (Hard to determine, Markings on tubes nearly worn off when 
I got it)
B-54364 x5 - NOS (Odd dual symbol tube)

Numitrons:
RCA DR2010 x3 -  2 Used, 1 NIB (Haven't tested them yet but look good)

Nixie Sockets:
Burroughs BIPCO BIP8211P x1 - Used
Burroughs BIPCO BIP8804-1 x1 - Used
Burroughs socket for 8422 nixie x1 - Used
Tec Lite TNR-70 A (Transistor Electronics Corp) x1 - Used

[neonixie-l] Re: Old Russian Beta Radiometer

[Tyler Bourne]

I found a detector on ebay.  Will test it out when it gets here.
I'm not sure how they are driving the tubes since I don't see the usual 
driver chips.  I'll examine the board and see if I can figure out how 
they're doing it.
Also I have a video of the display.  Not a very good video but I'll take 
another when I have the detector.

[neonixie-l] Re: Ongoing project: 12 tube date + time clock

[Tyler Bourne]

Cool project.  I've done a bit of SMD and it wasn't too bad.  My soldering 
iron tip isn't the smallest but it was still doable.  The flux pen helped a 
lot.
That flyback power supply looks neat.  You could do that as a separate 
kit.  People are always looking for a good Nixie PSU.  
Would you be willing to release the schematics of the PSU?  I understand 
keeping it private if you would like to sell the modules.

Hello!  Just thought I would post since I've been lurking for quite a 
while.  
I'm somewhat obsessed with vintage display technology and vintage 
electronics in general.  
I have several clock projects in the works as well as a couple pieces of 
equipment that incorporates Nixies that I would like to get working.
I'll post about those projects eventually.
