Re: [neonixie-l] Custom text discharge tube
Since then, I've done a couple of Panaplex-like displays (first, second), and more recently a text discharge tube, which I though you might be interested in. I'm trying to find out if there's any interest in a custom tube like this with your name or whatever spelled out in it. They're argon-filled and have a lifetime of about 150 hours. If anyone would like getting a custom one made, just drop me an email. That's nifty! I don't know how I missed it, since I've been looking at your laser cutter documentation while hacking up my own laser cutter. What are you asking for a custom tube? - Regards, John -- You received this message because you are subscribed to the Google Groups neonixie-l group.

I have been working with Carl and another forum member and have had a batch of PCB’s made per his gerber files. This has resulted in my building an open-top version of his clock using Carl’s software which can be seen here on my site: http://www.badnixie.com/The_%22Modular%22_Nixie.html and also on Brian Stuckey’s site: (scroll down a bit)http://www.tubeclockdb.com/nixie-clocks.html We have received some inquiries about offering a kit like the clock you see here. It would be complete with the acrylic top, drilled and tapped base plate, colon towers and the whole nine yards. So, we’re trying to determine if there is enough interest to make an initial run of 10 kits. We are not sure of the selling price yet, but our driving force here is to offer a product to the community that fills a void, not try to gouge our brethren. Note the aluminum fab’d bracket mounting the rotary encoder. This will be replaced with a right angle rotary that will mount directly to the PCB. Carl plans to do a little more tweaking to the software as well. Also there is a fair amount of SMD component soldering involved by the user and the kit will be offered without tubes. Here is a list of the feature set as it stands now. ==Unique Rotary Encoder User interface ==Auto Display dimming feature via photo sensor ==Adjustable DIM and Brightness levels with Adjustable Dimming threshold ==QuickTime Set feature- quickly and easily set current time without entering config. mode ==9 Selectable FONTS ==Clock spells out the Month and Day of the week, also displays date and year ==Four user selectable colon modes- OFF, ON, BLINK, ALT, or RAILRD (railroad) == TCXO time based ==Time On/Time Off sleep setting ==Smooth Digit Cross Fade feature with fade rate adjust. ==12/24 hour display mode selection ==Leading Zero Suppression selection ==Adjustable Pulse width Modulation setting value. ==Light Value Test Feature to determine optimal dimming point ==CW/CCW Rotary encoder direction selection Your feedback is appreciated! -- You received this message because you are subscribed to the Google Groups neonixie-l group.

Nick Nick, I understand that the lawyers want to make sure that you understand the regulatory obligations endured by the company before doing business with them. But... making the visitor agree to ten pages of legal boilerplate to view *anything* on the website? That's so wrong that it's funny. Its not wrong, it is a statutory requirement by the applicable regulatory authority. Look at any hedge or boutique investment fund site and they are pretty much the same. One thing to note is that hedge funds are pretty secretive about exactly what they do (they regard that as part of their competitive edge), so most of their web sites have scant real content and are there as a presence only. Strangely (!!), funds like this don't get passing trade - investors don't look at the web site to see if they are deserving of an investment ;-) Most funds are not allowed to sell to the general public (aka unqualified investors [aka non-professional]) anyway as the risks are considered to complex and too large. Most funds I've worked with are required by law (in the UK) to actively qualify all investors to ensure that they are professionally aware of the risks - a professional investor has to meet several requirements, some of which tend to include significant proven trading activity over a prolonged period together with significant minimum investments, e.g. maybe $1M or more in liquid capital and fund unit sizes of USD 50, 100 or 500K (depends on type of fund and target investor). Some funds target only HNWI (high net worth individuals), some institutional investors (pension funds etc.) and some are referred to as retail (general public, but at far lower risk). Enough already on hedge funds... Nick -- You received this message because you are subscribed to the Google Groups neonixie-l group.

[neonixie-l] Re: Custom text discharge tube
Thanks! Not entirely sure about the lifetime - I suspect it's something to do with the large cathode area I've got (as a result of the way I made the cathode form steel sheet rather than wire). I guess the lifetime could be improved a lot by using neon (smaller atom mass, hence less sputtering) but I'd need to get hold of some first ;-) -- You received this message because you are subscribed to the Google Groups neonixie-l group.

I guess the lifetime could be improved a lot by using neon (smaller atom mass, hence less sputtering) but I'd need to get hold of some first ;-) Marcin/John - I've sent you a pm regarding the tubes Yes, I saw Claude Paillard's video a while back and it was truly inspiring! The induction heating bakeout is probably essential for high-vacuum tubes (triodes etc) - I don't know about higher-pressure tubes like cold cathode devices. I was hoping that it wouldn't be so critical. That's a good point about the gas pressure - bit counter intuitive! You'd think that lower pressure would be better because you've got fewer atoms hitting the surface, but of course they'd be striking at higher energies. A nixie book did say that it is best to use the highest pressure possible, to avoid sputtering (it also gives you a good reservoir of gas). Trouble is, you often need to lower the pressure in order to get a uniform cathode glow at a reasonable tube current. Mercury seems to have a huge impact on lifetime as well - Bylander's book Electronic Displays has a graph of lifetime with and without mercury, and mercury addition is something like 20 times better. But I'd rather not be messing around with mercury! Cheers, Lindsay -- You received this message because you are subscribed to the Google Groups neonixie-l group.

[neonixie-l] Re: Custom text discharge tube
Hi John, Thanks for the interest in a tube! It takes me a couple of days to make it and test it in operation, so I'd be looking at around £200, which would include postage to anywhere. If you're interested, let me know what letters you'd like displayed, and I can send you back a design of what the cathode would look like, to see if it's ok. Thanks again!
