Bullshit, I did not remember you when I was at the Philips CRT plant, there was a complete bobine of chrome-nickle steel wire of about the thickness you used. Problem would be to weld it to the feed-trough wires. Soldering this wire is not possible; it has to be spot welded. In case you have interest, I can send you some photo's of things I met there, to give an idea. So I have here a frame, that is used to align the electrodes in a electron gun, that might give you an idea how to align the figures in a nixie. The frame is also used to press the glass ceramic studs that keep the electrodes in place in the tube. Also interesting photo's I made of a glassblower's tourch and the several satellite burners to place on top. Sadly I forgot to take a photo of the machine that does the work. I was too busy for a TCA member in Australia who has interest in materials and equipement for his experiments to make klystrons. There where rows of micro spotwelders on long tables, but it was too much work to remove them. I found one spotwelding head that was not mounted and a transformer for 5 V 330 A. I could take it home. Unfortunately the welding head is missing some parts, however, I think a can fix that. The price was low enough to take the risk. The most imortant is to develop a driving supply that doses the current and time. Powerelectronics are not really my favorite field.... eric

Thanks! The tube does not have a high lifespan: I used ordinary Dumet wire for the digits as well (convenience) and this sputters nicely; also, air is not the most ideal gas for discharge tubes, although it does look very nice (much nicer than I ever thought). I briefly thought about making some more of these (maybe 10) and build them into a binary clock or something ;-) But driving them is not practical because they do need 550V DC to strike. Jens Nice! So when are you ready to take orders? ;) /Martin On Tuesday, October 16, 2012 3:56:02 PM UTC+2, Jens Boos wrote: Hi folks, I did it: I have just built my first two-digit Nixie tube! I call her "NX-LS-1". She contains the digits 0 and 1 as well as a zig-zag anode. Filling is (as usual) air at 15mbar. I will have my needle valve shortly, then I will be able to do some neon thingies.
