Re: [neonixie-l] Re: Low profile board for Dalbors tubes

[dixter]

HI Richard... Please put me down for a kit or two when you make them 
available...  I have the tubes and your design looks like a great clock in 
the making...

thanks

[neonixie-l] Re: Info on IN-3B lamps

[Dekatron42]

This Russian website has a little information on them but even there they 
are not sure of their manufacture and data - they are used in Christmas 
lighting and also some photo lamps.

some more items using them:

You beat me to it, Martin, but it's a good thing I was interrupted before 
sending my reply. If nothing else these links saved me the trouble of taking 
photos.  8D

Martin, thank you very much for finding that site!!!*_*

I have two of those stars. One of my other hobbies is collecting old Christmas 
lights and I have a number of Soviet "New Year's" (most definitely not 
"Christmas") lighted decorations. I use a variac and a 1:2 transformer to get 
220V RMS.

I've seen them referred to as both IN-3V (ИН-3В) and IN-3B (ИН-3Б) on eBay but 
this Russian site is a gold mine of new info! 22kΩ it is.

My first thought is that the fill gas contains some mercury because the blue 
glow is coming from the glass itself. I have a mercury spectral lamp and when I 
first powered it up the glass fluoresced much brighter (in the visible 
spectrum) than the ionized mercury. Perhaps the power supply I had on hand was 
supplying too much current. If so, I only used it for a brief time and 
hopefully no harm was done.


Also, digital imagers are sensitive to UV and direct exposure to a UV source 
can appear as a bright magenta, meaning that UV is either passing through the 
red filters in the Bayer matrix or that the filter material itself is 
fluorescing. 

I need to do some research on that as it spoils my Halloween videos. I have 
camcorders with both CCD and CMOS imagers and even with the exposure greatly 
reduced a 15W "black light" fluorescent tube is so bright that the blue and red 
pixels are fully saturated at 255.

A regular "UV" filter (not a skylight filter, although those are 
supposed to be a more aggressive cut) does not help?  I know with some 
camcorders you would have to tape the filter to the front of the lens. 
The UV filters were intended to cut the Blue Haze when using Kodachrome, 
and so some sold these days are just "Protection" filters to keep the 
lens clean.


Might be worth a test with both the UV and Skylight to see what happens.

Those look like something someone made at home, or at least something that 
could be made at home with the right setup.
