Re: [neonixie-l] Re: Nixie tube making: first glow lamp up and running
Hello Dylan, Do You have any tips for seed beads thin enough? It should be 1mm, I found some 2mm, but this would make a potencial in the nixie different, so the breakdown voltage could be different for each digit. I read in a Weston:cold cathode glow discharge tubes that it should be 1mm. As John wrote, I found a supplier in Germany with nice 1mm alumina spacers, but one piece would cost around 3 EUR :-) little expensive..

If you've got ultrasound, I recommend it- there can be a little refractory sludge in 'em from the production. I made a few 'crackle' tubes using black seed beads and neon about 10 years back...really cool effect. -Dylan On Friday, September 28, 2012 7:09:57 AM UTC-7, jrehwin wrote: it is not so easy, the total surface of each digit should be constant to achieve constant current and constant brightness of each digit (else You will have to struggle with resistors on cathodes..).

I made a few 'crackle' tubes using black seed beads and neon about 10 years back...really cool effect. I made a crackle tube with glass beads a while back too - they were a little larger than the seed beads, but they were clear, and worked reasonably well. I tried it with an electronic transformer, but didn't get the crackle effect - I eventually went to a 30mA magnetic one, which did the trick. - John -- You received this message because you are subscribed to the Google Groups neonixie-l group.

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!

Re: [neonixie-l] Re: Nixie tube making: first glow lamp up and running
Hi folks, just a small follow-up on my first glow lamp post: I have managed to make a pinch seal using the 9mm tubing with four electrodes. The next aim is five. It is quite easy: all you need is very small glass tubing. Just stretch 9mm tubing, and if you do it fast enough (and carefully, of course) you get very nice small tubes with diameters below 1mm. Then I just cut these to pieces of 20mm and insert a Dumet wire each and heat it up with a small handheld torch. Then I align four of these wires and use a small portion of glass to glue them together. Then comes the pinching process which is not so critical if you have ensured all the four wires stick together good. Will document that on my website soon. So now I have a glow lamp with four more or less parallel wires... Could you call that a Nixie tube? ;-) Jens I also want to try to make evacuation pipe in stem, but there will be too many wires, how do You solve the problem of wires on the place of the pipe? I cant see that detail on your photo.. I'm curious too - that's a lot of wires for a pinch seal. Do You think that original industry made nixies used photo-etched numbers and anode mesh? Or it was stamped? You found a layouts or finished 5 and 7? This is a part of mosaic what I still miss :-) Instead of starting with existing nixies, I've been playing with generating cathode graphics using computer fonts. This one is just a test, I'd probably want to use a lighter typeface for real nixie cathodes: http://www.vitriol.com/images/tech/nixies/cathodes.gif - John -- You received this message because you are subscribed to the Google Groups neonixie-l group.

Re: [neonixie-l] Re: Nixie tube making: first glow lamp up and running
accelerated by Dalibor I tried my photolitography devices. It's very good, even using first time! It isn't simple technology but I'm very glad. In the second picture you have anode of nixie tube prepared from template of polish tube type LC513. Unfortunatelly I had old photosensitive lacquer and thick metal plate (0.2 mm). www.tubedevices.com/alek/pwl/lc1d/fotolito.jpg www.tubedevices.com/alek/pwl/lc1d/fotolito1.jpg Best regards Alek it is not so easy, the total surface of each digit should be constant to achieve constant current and constant brightness of each digit (else You will have to struggle with resistors on cathodes..). Bigger number = higher current.. While this is true, it isn't an absolute. Existing nixies have different currents for different digits (particularlay 1). Since they're more-or-less constant voltage devices, the anode resistor tends to even out the different current draws. Running nixies from higher voltages with larger anode resistors helps with this (at the cost of efficiency). Some designs actually use current regulation instead of anode resistors, and these will tend to overdrive the smaller digits slightly. That said, it would be simple enough to write code to adjust the digit stroke thicknesses to achieve matching total areas. Note that in some nixies, the 1 digit is made with a double stroke to help with this. And I also like the retro look of original digits ;-) That is a perfectly valid reason. If I were going to clone a nixie, I'd choose the CD-66 with its particularly nice digit shapes. However, if I'm making my own nixies, I'd be interested in making them visibly distinct from existing ones. If I want a CD-66, I can just go buy one (unless I want a CD-66 with 30mm digits). If I want a nixie with Böcklin or Klingon digits, I'll have to make my own. There's also a mechanical consideration - thicker digits will be more rigid and stable, and should survive longer. However, this thickness can be in material thickness or stroke width. Once I have working tube (as close as possible to original) I can play and change things inside.. Absolutely. Coming up with digit shapes is likely not the most difficult problem in making nixies. Have You made something working with mentioned digit graphics? Not as of yet. My original plan was to photoetch them, but I just heard from someone who's making custom variable capacitor plates, and has access to a water jet cutter. I've been pricing the little ceramic rings used as insulating digit separators, and they're expensive, so now I'm thinking of glass and mica as alternatives. - John -- You received this message because you are subscribed to the Google Groups neonixie-l group.

Re: [neonixie-l] Re: Nixie tube making: first glow lamp up and running
Dear Dalibor, good job! I just started preparing glass wafers with pumping pipe: http://tubedevices.com/alek/pwl/splaszcz/splaszcz30.jpg Yesterday I found devices for nixies (photolitography process for polish LC513 tubes). Unfortunatelly I have only 5 and 7 and grid templates. I wonder about photosensitive emulssion. Any suggestions? Hello, Thanks, I scanned numbers from z566m, so 30mm.
