You have beautiful blog with good pictures! As Vladimir sad Kovar (Rodar) alloys work the best with the borosilicate glass. You can try to make the kovar glass metal seal by yourself, but it's little bit problematic to get the material. If you want to experiment I have some amount of kovar wire and I can share some for free. Anyway, try to flatten the metal in the place of seal, it will release glass tension.

Re: [neonixie-l] Re: looking for Weston: Cold cathode glow discharge tubes
Hi Vladimir, thats nice to hear about small nixies, I am going to make nixies in size of ZM1040, and then I will go for much bigger tubes ;-) The book will be tomorrow.. As for the cathode material - I think stainless steel in combination with mercury dispenser were used in latest nixies, so it will be better than molybdenum. I will work with mercury, it is toxic, but it is not so bad.. it doesnt change a DNA, it doesnt make a cancer and the halflife of it in human body is 50 days.. (50 days and a half of mercury in your body is away..). I am curious about laser cut cathodes! I tried to write to Moore company about stems, but no answer, what companies did You write to? I would also buy some borosilicate stems.. Do You know something about how the stems are made? You wrote something about tooling - I have no idea about tools to make it, probably some drilling machine.. As for the glass - I use Simax, local producer, it is also borosillicate (3.3) glass, good experience with it..

Thanks (about designer) :) About Kovar, give me your adress and I will send you (to email of course) About webpage I don't have, now I'm studying Master's degree so I completely have no time to make one. All my spare time goes to build my little home workshop and it goes very very slow... Maybe in summer... (Just an idea) My first thought was when I came to this forum and saw that there are people here who are trying to make tubes, is that we need to create some sort of web page or Pdf document which brings together the information in a simple way about creating tubes and nixies, I know that is very big amount of information - but we can cover at least a very basic information to begin with, about, lets say - glass types some information about gas mixtures used in nixies glass metal seals basics, pressures and what sort of vacuum pump is needed and ... etc. For instance I still don't know exactly what kind of vacuum pump I need to purchase... and searching for the information sometimes takes sooo long time... So in the end it will simplify the process for those who are interested in creating lamps. I can offer my skills in graphics, 3D and animation.

Thanks Martin, It is of course technically possible to use dekatrons, but are there any that are small enough for use as a wrist watch?

[neonixie-l] Re: Kopriso Nixie Watch third glimpse
Ohh, I would go for just one watch if I had the parts, mass production has never been my focus as I just do these thingd for fun and because I can. I guess that the Burroughs Self Scan design is the smallest dekatron- like object there is, I have not seen anything similar from any other manufacturer. It would however need some re-design to work as a true dekatron with output cathodes if you'd like to drive a Nixie from it, otherwise a combined design with a Dekatron and the ZM1050 (Z550M) pixie would have been nice too. The smallest dekatrons, to my knowledge, with output cathodes which could drive a Nixie via a transistor is probably the ZM1170 / Z504S types which come in a 13 pin B13B socket, the same socket that ZM1040 Nixies use. The smallest ones, to my knowledge, which you can use to drive a Nixie with directly are the GSA10G / GCA10G (similar designs are Z572S / Z573C). I'm making a clock with the GSA10G's but it is really slow progress as my family and work takes most of my time. /Martin On 12 Maj, 00:18, Cobra007 mic...@xiac.com wrote: Thanks Martin, It is of course technically possible to use dekatrons, but are there any that are small enough for use as a wrist watch?

[neonixie-l] Re: Kopriso Nixie Watch third glimpse
Nice tubes, had a look at some on youtube. They still seem relatively large. If there was a dekatron that would fit inside a B4998 envelope it would more appealing. I think family and work is for most of us the reason why projects take more time than initially planned :-) I usually start too many projects at the same time because I want to try out all of them :-) Michel On May 12, 8:32 am, Dekatron42 martin.forsb...@gmail.com wrote: Ohh, I would go for just one watch if I had the parts, mass production has never been my focus as I just do these thingd for fun and because I can. I guess that the Burroughs Self Scan design is the smallest dekatron- like object there is, I have not seen anything similar from any other manufacturer. It would however need some re-design to work as a true dekatron with output cathodes if you'd like to drive a Nixie from it, otherwise a combined design with a Dekatron and the ZM1050 (Z550M) pixie would have been nice too. The smallest dekatrons, to my knowledge, with output cathodes which could drive a Nixie via a transistor is probably the ZM1170 / Z504S types which come in a 13 pin B13B socket, the same socket that ZM1040 Nixies use. The smallest ones, to my knowledge, which you can use to drive a Nixie with directly are the GSA10G / GCA10G (similar designs are Z572S / Z573C). I'm making a clock with the GSA10G's but it is really slow progress as my family and work takes most of my time. /Martin On 12 Maj, 00:18, Cobra007 mic...@xiac.com wrote: Thanks Martin, It is of course technically possible to use dekatrons, but are there any that are small enough for use as a wrist watch? Also, to make it worth the effort, you need quite a stash of those tubes, I mean it doesn't really make sense to spend all this time designing it and then only have enough tubes for 10 watches :-). Another possible problem could be the brightness of the tube cathodes. The dekatron only lights up only a small dot rather than a whole digit. I like the idea though!

[neonixie-l] Re: Kopriso Nixie Watch third glimpse
Yeah, I can see potential in that one. But how can you turn that into a clock? It would have been great if it had 12 segments rather than 10. Otherwise you need 1 tube for each digit and some form of face plate to show the number it actually represents.

[neonixie-l] Re: Kopriso Nixie Watch third glimpse
The obvious solution is to geek out completely and make a dekatron watch that tells time in metric! Use two A108s and divide the day into 10 hours of 100 minutes, then have the first tube display hours and the second 10s of minutes. Sure, nobody is going to be able to read the thing, but once you get to the point where you are seriously talking about building a dekatron-based watch, I think all hope of having a practical device has been thrown out the window already. Ultimately building a dekatron watch is to doable though, to really break people's brains you are going to have to build a watch out of direct view beam switching tubes. http://www.decadecounter.com/vta/articleview.php?item=1090 If someone manages to actually pull that off, they could probably somehow tap their own lack of sanity as a power source... -- You received this message because you are subscribed to the Google Groups neonixie-l group.
