Ahh I see. I suppose nothing that would be physically similar looking to a 
standard nixie display with layers of cutout digits as cathodes

[neonixie-l] Green Nixie tube?

[Miles Thatch]

Good day, everyone.

I'm wondering, do green Nixie digital display tubes exist? From what I 
understand, the color of the discharge depends on the vacuum and type of 
gas but I've not seen any images showcasing one with a green color. Is 
there such a thing?

Re: [neonixie-l] Re: Welcome & please introduce yourself!

[Miles Thatch]

Good day, everyone.

I'm just getting into the subject of Nixie tube making. I have gotten to 
work with some new old stock nixies and some de-soldered miniature digit 
tubes and now I'm curious about the process of manufacturing my own. I 
found the Dalibor Farni channel 
to be extremely 
fascinating, and the video by jdflyback  
where 
he has actually made a 3 digit cathode ray tube 
 with perhaps less tools which 
you and I might have got me thinking of dipping my toes into trying to make 
one myself as well.

This is also something I wanted to do in order to provide a fallback for 
nixie tubes availability for this project. A post apocalyptic handheld text 
based adventure game. I wanted to make sure I don't depend on the 
increasingly expensive and fleeting stock of overseas shipped tubes.

The battery backs up the time, not the settings. If you lose power you have to 
reset the 12/24 hour display mode, auto shutoff and background color settings.

Re: [neonixie-l] Anyone purchased one of these clocks?

[Terry S]

Dan, I need to disagree with you on several counts. It's an .062 board and 
the vias are small. Plenty of space between D+ & D- and the ground plane, 
at least 10 mils. It's likely just a 2 layer board, but as someone who 
spent 25 years of my career designing PCBs, I find very little fault with 
this layout. 

Traces are 6 to 8 mils except for power distribution & HV. The layout is 
fairly clean and well thought out. The silkscreen is very good and I found 
no acid traps. Trace to trace clearance looks a bit small on signal lines 
but it's nothing that can't be manufactured reliably today. The simple 
architecture is a bonus in my opinion. 

He used copper pours a bit inconsistently but it's not a crime on this tiny 
board. 

Overall it's a competent design and quite a bargain. If the code was open 
source I'd certainly change a few things with regard to setting time and 
button operation, cathode poising routine, etc. But for this price it's a 
great little clock and a nice gift item.

Yes setting the time and backlight is rather twisted.

Re: [neonixie-l] Re: just wondering what these tubes G10/241E go for

[Jon]

Not quite what I said. At the top end of the condition range, by 'a few 
tens of dollars'  I was indicating something in the $20 - $50 region 
depending on the specifics of the particular tube and market appetite at 
that time. G10/241E is not a common tube, but it's also not a real rarity.

Having said all of that, there's always some eBay seller who'll put a $75+ 
price tag on a tatty 'untested' (but very likely dead) tube, and hope to 
get a bite... But those usually don't sell. Never to me anyway :)

['Grahame' via neonixie-l]

I have two G10/241E and both are dead unfortunately but physically 
intact.

While we're on the subject of STC counting tubes, does anyone have a 
working G10/240E (note different number) that they'd be interested to 
sell? PM me if so!

[neonixie-l] Re: just wondering what these tubes G10/241E go for

[Jon]

Primarily a tube collector item I'd suggest. They're fiddly to drive and 
the display is much less visually striking than other dekatron types, so 
there's not a lot one can do with them in the direction of a clock or 
similar. And then there's the question of condition - many G10/241E don't 
work now, even if they're apparently NIB (there's a 'death in storage' 
problem that afflicts many high speed dekatron types including this one). 
And the metal base shell is prone to cracking and falling off the tube 
which is cosmetically unattractive.

So a scraggy tube without proof of function is pretty worthless IMHO. At 
the other end, a tested mint tube in the original box is probably a few 
tens of dollars, depending on how interested the small pool of likely 
buyers is at that moment. If you've got one of these you might want to 
sell, you're welcome to PM me some pictures and I'll try to give some more 
specific input - I've done quite a bit of historical research on these 
tubes. They're actually a really early solution to the counting tube 
problem, but one which largely lost out in commercial use to the more 
elegant and flexible Ericsson designs.

While we're on the subject of STC counting tubes, does anyone have a 
working G10/240E (note different number) that they'd be interested to sell? 
PM me if so!

Cheers,

Jon.
