Re: [neonixie-l] Re: Nixie tubes in movies

[Nick Andrews]

I suspected as much due to the way the digits looked.  On a tv it is hard
to notice,  but on the big screen it kinda stuck out.  Of course it still
made the typical Hollywood clicking sounds,  like geiger counters that
don't have audio clicking away in movies...

[neonixie-l] Re: Troubleshooting 3-guide dekatron

[Jon]

Difficult to say for sure without seeing the circuit, but if it spins fine 
one way but not the other, most likely you've just got a bit of a sticky 
tube. Particularly if the performance is improving with use - it's a very 
common observation when waking up dekatrons after a few decades asleep, 
though some models are more prone to it than others. I generally find that 
a few hours use clears up most of these issues and it doesn't seem to 
matter too much how fast you spin it while doing that. I'm drawn to the 
idea that a slower step should be better - give a little bit more time for 
the glow to really heat up the cathode and burn any crud off it. But I've 
no objective evidence to support that view - difficult to do controlled 
experiments. If you get a really recalcitrant cathode, then sometimes 
letting the glow rest there for a couple of minutes while running the tube 
at a current a little above the maximum rated value can be useful. What 
current are you operating the tube at?

Having said that, can you tell which cathode seems to be sticky? If it's K0 
or the guide pins immediately either side of that, then you might have a 
tube which has been heavily used in an application where it's been stuck on 
one cathode (usually K0) for many hours. That can cause erosion of K0 by 
sputtering and deposition of material on the faces of the neighbouring 
guide cathodes - in both cases the surface properties of the cathodes are 
changed which can cause stickiness. And in bad cases that can be incurable. 
It's more of a issue on the neon-filled tubes though than the 
helium/hydrogen ones like your OG3 (there is no argon in there BTW, that's 
an oft-repeated error).

Jon.

[neonixie-l] Re: Troubleshooting 3-guide dekatron

[gregebert]

The reason I suggested boosting the cathode voltage was based on my own 
experience with the A101; apparently I misread the datasheet and thought it 
needed about 15V, and it didn't work smoothly. After boosting it, it ran 
much better. At 45 volts, your design has plenty of margin for the A101 and 
the OG4 based on the datasheets I found online. If the current is correct 
(400uA), the only other factor you can control is the timing.

Once you have it working smoothly, try reducing your anode voltage to make 
sure there is some margin in the design, so that as the tube ages it will 
still work.

[neonixie-l] Re: Troubleshooting 3-guide dekatron

[Andrew ODonnell]

Thanks for the tips

I have an A101 and an OG4 running great on the same circuit - just having 
issues getting the 3-guide OG3 running (i'm aware the OG3 needs more 
amperage and a different drive circuit and it's got that). Anode to main 
cathode voltage is about 225 and Anode to Guides is about 180 so yeah about 
45 volts drop for the guides compared to the main cathode. 

What makes you suggest a slightly higher voltage drop at the cathode 
resistors - something about the appearance?

As for drive, i've taken a fairly simple 4-step approach (I can reverse the 
direction and it doesn't stick so i'm happy the drive is working unless i'm 
missing anything?)

It's been running for about 2 hours now and it's improving constantly - 
much less sticking each time, so I suspect it's mostly the Dekatron itself 
being sticky. I'll leave it overnight and see if this helps. it's probably 
also worth noting it only sticks clockwise - if I run it anticlockwise it 
spins fine.

Re: [neonixie-l] Re: Who is interested in IN33?

[Andrew ODonnell]

Hi

I'm interested in following;

2x IN-33
1x A-108
2x IVL-2-7/5
1x IVL-1-7/5
2x IVLShU-1-11/2

please. Ship to UK.

Also the OG-9, price and is it metal base or plastic/bakelite? Am I right 
in thinking the OG-9 is almost identical to the OG-4 (double pulse 30 pins 
etc)?

Thanks

[neonixie-l] Troubleshooting 3-guide dekatron

[Andrew ODonnell]

Hi

I'm playing around and familiarising myself with Dekatrons. Have an 
arduino-interface PCB so running them off Arduino. OG-4 and A101 running 
nicely but i'm struggling with the Argon 3-guide tubes.

Here's a video of what it's doing - it looks like it's driving correctly 
but it's failing usually at the same pin everytime. But sometimes it's 
circling nicely.

https://photos.app.goo.gl/tznRK8o7DN14wGbX7 

Is this a hardware fault ('sticky' pin on the dekatron) or is this a fault 
in my software to drive it?

I know some Dekatrons can be a bit tricky and sticky, if this is just a 
sticky pin, what's the best way to try and resolve it? If the answer is 
'run it for hours' - is it best to run it super fast or slow?

Many Thanks
