Re: [neonixie-l] eBay: Omni-Ray for sale!
The pattern on the film isn't that difficult to figure out, though printing it in perfect alignment at exactly the right scale might be a challenge. For each "lenslet" (pixel) in the array, there must be 12 possible clear dots in the film, aligned similarly to the bulbs but inverted. For each displayable symbol, the dot corresponding to that bulb's position will be either clear or black. So to light a "0", the dots on the film in the zero position in front of each lenslet must be set appropriately for the shape of the "0". If you're really clever you could even try antialiasing the curved and angled edges of the symbols... Near the top and bottom center of the Message Assembly, should be several pixels with 10 of the 12 possible dots being clear - every symbol but the decimals will light those pixels where they all intersect. Conversely, the upper corners of the film should be solid black since nothing should ever be lit there; judging by the size of the "3" and "4" shown on Dieter's page, none of the symbols should occupy the full width of the top of the screen, nor even extend fully into one upper corner.

[neonixie-l] Re: eBay: Omni-Ray for sale!
Yes, it makes a dot-matrix sort of pattern, but not bulb-per-dot. Like ordinary projection readuts, it uses one bulb per symbol, but rather than one lens and one image per bulb, it uses an array of lenses and some optical trickery to create the symbols.

[neonixie-l] Re: Nixie tube at 300 000 V
I followed the link to Chris's theory of operation paragraph, and I believe he is misinformed about where the glow comes from. Sputtering is not necessary for a nixie tube to function; the atoms which become excited and then emit photons as they return to their normal energy state are the gas atoms. In the case of nixie tubes, that is primarily neon, a little bit of argon, and in most tubes, some mercury. Sputtering of the metal is merely an unintended consequence of the electric field and current flow causing some of those gas atoms and ions to collide with the cathodes at high kinetic energy levels. In normal operation of a non-mercury tube, those sputtered atoms do not significantly contribute to the glow discharge. In a tube with mercury, the theory is that the mercury (liquid phase) coats the surface of the cathodes, so when sputtering occurs, it will be mercury atoms that are knocked free. Since mercury (gas phase) is present in the tube, there will then be a state of dynamic equilibrium reached wherein as many mercury atoms rejoin the cathode surface from the gas fill as are being stripped; thus the net result is ideally no cathode erosion and no silvering of the glass.

Re: [neonixie-l] Re: b7971 segment current
You got that backwards. Unused digits/segments in a nixie become "poisoned" by stuff given off from the active segments. Trying to light those middle vertical and diagonal segments in a tube from a well-used "Giant Nixie Clock" from the early 1970's now, might reveal that those segments don't light at all. They may also light dimly, partially, or unevenly. They might be shorted to the back substrate and possibly even each other via the substrate. Or they might work just fine; those are large tubes and any given point on one segment is on average much farther away from the nearest point on each other segment than typical cathodes of small conventional nixies. But I can't think of any reason why they would ever be brighter than the segments which have been in use.

For anyone who wants to make a note of such things, the original brochure #616 contains an error on page 26. Scroll down to the "SUPER SIZE" table, entry for B-6012. There is a cross-reference to earlier part number "BD-214" as being equivalent. This is a mistake, as you will probably have noticed BD-214 was already mentioned in the "STANDARD SIZE" table. The correct equivalent part number for B-6012 is BD-225. Not that anyone would actually want to use them now anyway, since they are non-mercury "standard life" tubes (i.e. very short life).

Re: [neonixie-l] Re: These don't come up very often...
There are tricks I've discovered that allow one to see items that don't ship to their country in ebay searches. One parameter that ebay fortunately currently does NOT check with respect to location restrictions, is your IP address. So, besides setting the "worldwide" radio button, other ways ebay knows where you are include your account settings, and the exact ebay site you're using. The ways around those are: 1) sign out! and 2) use the TLD of the location you want to check, if known. For example, ebay.de (Germany) or ebay.co.uk (United Kingdom). Beware that in some countries the category tree will be radically different from what you're familiar with. For example, the structure of some of the technical categories at ebay.nl (Netherlands/Holland) is greatly simplified compared to those on ebay.com -- in my experience, not a good thing. Once you've found an item using these methods, it's usually still possible to contact the seller to find out if he'll make an exception for you. In case of an absolute "must have" item an an unwavering seller, there are also services available by which you can pay a small fee to have an item delivered to an "acceptable" address for the seller, then re-shipped to you anywhere in the world.

Correction, one can use diamagnetism (opposing ferromagnetism) to achieve stable, static magnetic levitation in a gravitational field.

[neonixie-l] Re: Finally, upside down nixies in use...
I have one of those counters too. The one listed is missing a tube and its front lens. The lens will be hard to match if someone wants to restore it correctly -- it's a dark amber circular polarizing filter; the few places that can supply this material call it HACP, and they charge an arm and a leg for it. Best bet is to rob one from a similar piece of equipment that's otherwise in worse condition, or just go with plain tinted acrylic.

Interesting that in the page you linked, the item name is "electron tube", but it's given in the site's "connectors" category. In my LED search, I've come upon a similar situation of a certain error that apparently originated in an OCR mis-read of a part number, that has been copied over and over to numerous "datasheet" sites. In this particular instance, absolutely nobody has a scan of the actual data online for the part number I seek... they all just keep reguritating the same wrong "short form" data that belongs to a different but similar part number. So not only is the part I want scarce and now practically unknown, anyone who came before me and bought up the last remaining stocks based on the available data, would have received parts that didn't match the data, unless they had a physical copy of the maker's original data book from the 1980s.

It's called lenticular motion effect or lenticular 3-D, depending on which effect is used; both work nearly the same way. Some products even combine both effects to produce a moving 3-D scene. Each vertical rib is actually a long, thin lens (like a bar magnifier, if you know what that is) and will magnify a very narrow strip of what's behind it greatly in width. The catch is, as your viewing angle changes even slightly, the strip that you're seeing changes position fairly drastically, just like the old alcohol-filled thermometers, with the super skinny capillary tube partly full of red-dyed liquid, that suddenly appears as a very readable wide stripe if you stand facing exactly perpendicular to the face of the thermometer. In the common lenticular motion effect, by interleaving several strips taken from different images in the same sequence behind each lenticular lens, the magnification effect lets you see each lens as being filled to its entire width with a little piece of the same image even though the actual bit of print you're seeing is really only a small fraction of the width of the rib. By changing your horizontal viewing angle, your view through all of the lenses in the panel shifts to the next strip in sequence behind each lens, and it seems as if the whole picture has suddenly changed. For the 3-D effect, the relationship between the printed strips and lens ribs and the geometry of the ribs themselves, are made somewhat differently so that each of your eyes will see a different strip in the sequence across the panel, and the printed strips are made from several different views of the same object or scene. For example, the simplest 3-D lenticular images typically use 5 different views of the scene. Looking directly at it from the proper distance, your left eye may see view 2 while your right eye sees view 4. Shifting your position a bit will let you see views 1 and 3, or 3 and 5. but if you move too far off-axis, you may see views 5 and 2 (for example), and lose the 3-D effect, or even invert it. Some 3-D lenticular images use strategically placed black strips so that by moving too far off-axis, the image simply blacks out.

I feel no electrical sensation. This isn't really a concern, just cool. This may be an item of concern. First, do you have bleeder resistors across any high voltage capactors in your circuit? If not, you should, for protection of anyone who may work on it. The neons could be lighting up from stored charge. Also, (assuming that the plugs of both the surge protector and the clock are either 3-prong or polarized) there may be a problem with either your power outlet or surge protector. Either the power outlet wiring's polarity is reversed, or the surge protector has its switch in the wrong wire. If your clock already has bleeder resistors, this is almost certainly the case. If you have any non-polarized plugs in the loop, one of them needs to be reversed, or better yet, replaced with a polarized plug installed properly. The miswiring results in the neutral wire being switched off instead of the live wire, which is a dangerous situation, and can result in just enough current flow to produce the phenomenon you described. I once had a gas range with electronic ignition that was on a mis-wired circuit, and even when it was off the electronic ignition would spark every 10 minutes or so, because the wiring capacitance allowed a trickle of current to flow backwards into the HV generation circuit, and it took that long for it to build up enough to flash over. When off, your clock may be generating a high voltage that is fairly low, perhaps in the region of 70 volts, that is just enough to light the neon bulbs with the additional capacitance from your hand.

There are no words... Jens Hybrid cars, here in the US, are officially listed as partial zero emission. My mother's non-hybrid Toyota Camry is also a PZEV. I'm told that this means that some of the time while the vehicle is running, the engine's fuel supply is cut off completely. For non-hybrid vehicles, this could only be while coasting at speed with the throttle closed. I guess the automatic transmission must be specially designed to keep the engine turning over with the torque input from the wheels.

This should be obvious, but you didn't mention it: did you check the tube itself by hardwiring it? It is not unheard of for nixies to develop internal shorts. -- You received this message because you are subscribed to the Google Groups neonixie-l group.

[neonixie-l] NEONIXIE-L Yahoo Group
News from the Yahoo front: Owner Ray Weisling has awoken from his slumber and revoked my moderator status, so I no longer have the power to make any changes there beyond what any member could. I didn't quite finish changing all of the member statuses, so there are about 200-300 people who joined within the last year or so who are still moderated, therefore their posts will not appear there until RAY approves them -- or if he takes more than two weeks to do so, the posts will be discarded. I hope someone has managed to save something of that group's archives, as they're now on even more uncertain ground, including most of what I have posted myself, as I did not keep the originals or any other versions of most of my photos. I find it interesting that Ray didn't immediately evict or ban me from that group, so I hold out hope that he isn't holding a grudge and will appoint someone else (hopefully more than one person) to take over as moderator, (or, dare I say it, owner) if he isn't likely to participate more in the near future than he has for the past few years.
