[neonixie-l] Nixie tube making: first glow lamp up and running
Hi folks, finally I got my first glow lamp working. It is the third try, therefore I call it "GL-LS-3", short for glow lamp lab sample 3. See two pictures here: http://www.jb-electronics.de/tmp/gl-ls-3_1.jpg http://www.jb-electronics.de/tmp/gl-ls-3_2.jpg It consists of 9mm soda lime tubing and Dumet wire. The gas filling is normal air at 9mbar. It ignites nicely at roughly 550V DC. I used a simple propane torch for the glass work. Will switch to a hand-held oxygen-propane torch in a few months though (when I have enough time and money). I will get my needle valve in two weeks or so, then I will be able to do something with neon. Believe it or not: over two months lead time for a silly needle valve... Anyway, I hope I will have the tube making content prepared for my website by then. It is piling up, but there is still much to do.

Nice work Jens! Would be a good combination, nixie tube clock with glow lamp colons or something like that. It doesn't seem as bright as neon but that is probably because it is a prototype.

Re: [neonixie-l] Re: Nixie tube making: first glow lamp up and running
Thanks Michel, I am planning to do all kinds of glow lamps before I get a real torch, a real colon display would be nice. Next, I will experiment with the aluminum oxide insulator. Sadly, it is quite brittle, so if you shake the tube too hard it will break loose. But I could use this insulator to prevent parts of wires to glow. But I doubt that air is going to get any brighter, Argon would probably yield much better results. Jens Nice work Jens!
