A recent thread on the rec.radio.amateur.homebrew newsgroup asked about homemade valves (tubes), see http://www.mindspring.com/~pfriedr/index.htm who has...
I recently heard from someone who is investigating just this - I recommend he joined the group - not sure if he has yet. The gist was that much of the cost...
Hi Hans ! ... If you look at the stuff that comes over from far east (china namely) and what was made in the late 80s in russia ... yes - it should be possible...
Just took delivery of the above nixie types and they look great. I have only connected to the anode and the 10 cathodes but see from the pinouts that some of...
Anybody ever heard of this one. Its a small stout envelope about 30mm high and 20mm wide. markings are MUDOX 3D4. Pins laid out in almost a square format at...
I used the Z568 (http://www.hanssummers.com/electronics/clocks/nixie/index.htm. I think "ic" means "internal connection". If I recall when you scrape the paint...
Click on the photos link to the left to see the pics. Really interesting i think. the screen is 360 degree all round and the glowing digit is visible from all...
Hello Thanks for the info. Building a nixie tube would be fun! 1. Why do you need to get the oxygen out of the electrodes metal? Is it because otherwise over...
... ..so you can induce heating in the metal when the tube is under vacuum. This may alternatively be do-able using a HV supply - neon sign makers call this...
... Is it ... gas? Why an Oxygen is a very reactive element, more so when in an electrically charged environment. Oxygen turns copper green over a period of ...
Hello All; I can't speak to the requirement to heat the metal to remove the oxygen (and fabricating the numbers sounds like it would be a very interesting...
... Easy - get them laser-cut. This is a routine industrial process, and probably not too expensive if you have enough done at one time to cover the setup...
Why do the numbers have to be made from nickel or titanium, could you not use ordinary copper? And can you solder the copper inside the enclosure or does...
Hi ! This "Mudox" is in fact the Valvo / Philips manufacturing code. The tubes were made for TV channel displays "in the good old times" - basically the tube...
Hi Hans ! Reg. Q1: There is / was a page on the 'net which showed a manufacturing process at Valvo. They induce-glow the metal of the tubes to avoid problems ...

WHich circuit board did you use for your Z tube clock? Is it a multiplexing design and are the tubes bright enough? Is there ringing?...
Hi ! ... That's what I had in mind. A neon sign maker has the capabilities of about 75% of the required technology to help making own Nixies. The rest is...

Hi ! ... In fact even german-language datasheets use "i.c." or "i.v." to mark internal connections. "i.v." in this case stands for "interne Verbindung"...
This is raw techtalk and I'm just not ready for that yet.. Can anyone decode it even a little bit for me ? I HAVE LOTS OF 8422 FROM HOTEL ATT TOLL PANELS ALSO...
