[neonixie-l] Buying Nixies from outside the UK
Hello as a relatively new starter with nixie etc I want to buy some IN14s and dekatrons. I am based in the UK and have been looking at UK suppliers with only two that I can find. One is out of stock. I have found some abroad in another EU country, which are much cheaper, but I'm not sure on two things. 1. Do they survive well travelling in the mail? 2. Are there any import restrictions to the UK due to the content ie neon etc? Sorry if they seem stupid questions.

[neonixie-l] Colophony
Liquid flux seems expensive to buy and it comes in tiddly bottles. I bought a solid tin of colophony, eg ebay item 121041198430, dissolved it in Isopropyl alcohol and it seems to make an excellent flux. Lots and lots of it can be made very cheaply. Can the experts tell me if this is a really bad idea or not? I do wash the board off afterwards, but with SMT chips I suppose it might leave some kind of residue under the IC.

Hi John, As long as the sender packs them adequately to prevent the glass envelopes breaking, you shouldn't have any problems getting them shipped into the UK. Take a look on eBay to check the prices that you're being quoted are reasonable. There are no import restrictions to the UK which have ever affected me. However, if the package is given a customs value in excess of £18 there's a chance Royal Mail will spot it and charge you 20% VAT + their iniquitous £8 handling fee. Nothing to do with shipping, but as a general principle with dekatrons do be aware that the exotic high speed ones have a significant dud rate due to loss of their magic fill gases in storage. Stick to nice slow speed neon ones and you should be fine. Jon.

[neonixie-l] For all tube self-makers
I have found that at Ebay: http://cgi.ebay.de/ws/eBayISAPI.dll?ViewItemitem=251235692223 Maybe interesting. Also see the list he wrote for future offers.

[neonixie-l] Re: OG8 dekatrons
I've played with og3's, I thought they were part argon, I might be wrong though. The only drawback for me was that they need 3 microcontroller pins, or some circuitry to provide the 3 phases to drive them. The brightness of the glow is also a bit less than a neon tube. I had trouble getting the reset to 0 working, and opted for 3 neurons detect on 0 approach instead, the tube is a seconds pendulum and mode function indicator for one of my clock projects.

I'm leaning towards hydrogen. If so, it'll react with the innards, and eventually, no joy. I haven't played with that tube, but I have looked at its datasheet, and its specs. Its similar to the OG-3, much in the same way that a GC10/4B is related to a GC10B, and a OG-9 is to an OG-4. In the OG-3, OG-4, GC10B, and 6482 only one cathode is brought out separately, while the others are ganged together. In the OG-8, OG-9, GC10/4B, 6802, a few of the other cathodes are also brought out separately, using up the remainder of the octal base pins. -- You received this message because you are subscribed to the Google Groups neonixie-l group.

| I've played with og3's, I thought they were part argon, I might be wrong though. | The brightness of the glow is also a bit less than a neon tube. There are other gases that glow blue/violet. The only reason, I'm thinking its not argon, is that argon is a larger atom than neon. The color does correspond to energy transitions, with violet having the most energy, and red having the lowest. Orange is just a tad more energetic than red. How that translates to ionization speed, I have no clue. I tried looking at the emissions of these tubes with a cheap spectrometer, but still got multiple lines. It really needs to be done with a good quality calibrated spectrometer, and in absolute darkness. Still, a single element will have multiple lines, and it still may be a mix, of several gasses. I've also heard helium tossed around. That also glows blue, and has the bad habit of being able to leak right thru glass. That was a problem we had with HeNe lasers. So other than the high dud rates of these tubes, the glow brightness, or lack of it, is a second strike against these tubes. The 3rd guide doesn't really bother me. Especially, when stepped by a uC. That means 40 rods instead of 30, for finer resolution. That's why I like using Japanese DK23 dekatrons, with my do-hickie circuit. 40 rods, and it glows orange ! Nice to hear someone else having a dekatron pendulum, as part of their nixie clock. Jason Harper started it a long time ago, and I've used it on 4 of my own, but I haven't made a new clock in ages. -- You received this message because you are subscribed to the Google Groups neonixie-l group.

Not in the UK, but I've been ordering stuff from former Soviet bloc countries for delivery in the US and only had one problem: http://www.tmk.com/blog/6F5S8816-s.jpg And that one was due to poor packaging, and the seller and I reached a mutually satisfactory settlement. I must have at least 5000 assorted displays here (Nixie, VFD, esoterica) and never had one damaged in shipment, other than the clock shown above. The sellers seem to do a good job of packing the tubes for shipment, using a variety of methods (anything from bubble wrap to decades-old newspapers / cardboard. There are some scammers out there, though - look to see how long the seller has been on eBay and how much feedback (as a seller) they have. It's a good idea to confirm that the quoted shipping cost is at least somewhat related to the actual post cost. Most countries have English- language versions of their web sites where you can calculate postage. The only one that I know of that's way off is Moldova - their English site quotes a much lower rate than the native-language version for some reason. -- You received this message because you are subscribed to the Google Groups neonixie-l group.
