On this page I have collected some nixie tube data. Although no longer in production, there's still huge stock of nixies. Now they are no longer manufactured [7][8] Russian ИH-12A (IN-12A) and ИH-12B (IN-12B) tubes use the number arrangement 3 8 9 4 0 5 7 2 6 1 from front (3) to back (1), with the 5 being an upside down 2. Citing dissatisfaction with the aesthetics of modern digital displays and a nostalgic fondness for the styling of obsolete technology, significant numbers of electronics enthusiasts have shown interest in reviving Nixies. Nixies exhibit negative resistance and will maintain their glow at typically 20 V to 30 V below the strike voltage. Only "Integral" in Belarus lists the 74141[14] and its Soviet equivalent, the K155ID1 [15] as still in production. [12] Unsold tubes that have been sitting in warehouses for decades are being brought out and used, the most common application being in homemade digital clocks. A few extreme examples of sputtering have even resulted in complete disintegration of Nixie-tube cathodes. [7] This recent surge in demand has caused prices to rise significantly, particularly for large tubes, making small-scale production of new devices again viable.

Unlike Nixies, the glass envelope of a VFD is evacuated rather than being filled with a specific mixture of gases at low pressure. LEDs are better suited to the low voltages that semiconductor integrated circuits typically use, which was an advantage for devices such as pocket calculators, digital watches, and handheld digital measurement instruments. Nixie tubes are susceptible to multiple failure modes, including: Driving Nixies outside of their specified electrical parameters will accelerate their demise, especially excess current, which increases sputtering of the electrodes. Other numeric-display technologies concurrently in use included backlit columnar transparencies ("thermometer displays"), light pipes, rear-projection and edge-lit lightguide displays (all using individual incandescent or neon light bulbs for illumination), Numitron incandescent filament readouts,[11] Panaplex seven-segment displays, and vacuum fluorescent display tubes. Such large types were not produced in large amount, as their use was not very wide. Indicating - through side panel of the tube. [12] Unsold tubes that have been sitting in warehouses for decades are being brought out and used, the most common application being in homemade digital clocks.

One such arrangement is 6 7 5 8 4 3 9 2 0 1 from front (6) to back (1). Some sources[2] suggest that incomplete glow coverage of a glyph ("cathode poisoning") or appearance of glow elsewhere in the tube would not be acceptable. The Burroughs Corporation introduced "Nixie" and owned the name Nixie as a trademark. particularly for the construction of a retro design digital clocks. The very … If you limit your search for the types that are more abundant, all statements are true. The term 'nixie' is actually a trademark of the Burroughs Corporation that has now become a generic name. A later form of trochotron called a Beam-X Switch replaced the large, heavy external cylindrical magnet with ten small internal metal-alloy rod magnets which also served as electrodes. Nixie tubes were superseded in the 1970s by light-emitting diodes (LEDs) and vacuum fluorescent displays (VFDs), often in the form of seven-segment displays. Most used a neon-based gas mixture and counted in base-10, but faster types were based on argon, hydrogen, or other gases, and for timekeeping and similar applications a few base-12 types were available. Types with two or three sets of guide cathodes could count in either direction. The current limiting is normally implemented as an anode resistor of a few tens of thousands of ohms. Applying voltage between the anode and one cathode, the respective cathode lights up (becomes surrounded by glow-discharge) and thus will display It was widely used as test equipment display's in the 1950's and early 1960's, as well as calculators, measurement readouts and other instrumentation.

It is used for displaying numbers or other symbols. Cathode poisoning can be abated by limiting current through the tubes to significantly below their maximum rating,[9] through the use of Nixie tubes constructed from materials that avoid the effect (e.g. Traditional nixie clock without MCU - only with logic circuits A related device is the pixie tube, which uses a stencil mask with numeral-shaped holes instead of shaped cathodes. Hundreds of variations of this design were manufactured by many firms, from the 1950s until the 1990s. In recent years there has been a groundswell of retro electronic builders using these as digital clocks, wrist watches, retro CD players and even punked up AM radio receivers. [citation needed] Equipment with Nixie-tube displays in excellent working condition is still plentiful, though much of it has been in frequent use for 30–40 years or more. Nixie Tube Power Supply A nixie tube power supply that I documented at hackaday.io. Because the numbers and other characters are arranged one behind another, each character appears at a different depth, giving Nixie based displays a distinct appearance. Z568M and Z5680M were the biggest nixies of Comecon. VFDs have a simple internal structure, resulting in a bright, sharp, and unobstructed image. The early Nixie displays were made by a small vacuum tube manufacturer called Haydu Brothers Laboratories, and introduced in 1955[5] by Burroughs Corporation, who purchased Haydu. Nixies exhibit negative resistance and will maintain their glow at typically 20 V to 30 V below the strike voltage. Also, LEDs are much smaller and sturdier, without a fragile glass envelope.

This is the "minimum operating life", which differs considerably from that of "average life" or "mean life". The glass tube contains a wire-mesh anode and multiple cathodes, shaped like numerals or other symbols. The VFD uses a hot filament to emit electrons, a control grid and phosphor-coated anodes (similar to a cathode ray tube) shaped to represent segments of a digit, pixels of a graphical display, or complete letters, symbols, or words. 0000000793 00000 n Average longevity of Nixie tubes varied from about 5,000 hours for the earliest types, to as high as 200,000 hours or more for some of the last types to be introduced. It is therefore called a cold-cathode tube (a form of gas-filled tube), and is a variant of the neon lamp. Crafting Nixie Tubes Since 2011. [8][13][7] During their heyday, Nixies were generally considered too expensive for use in mass-market consumer goods such as clocks.

The name Nixie was derived by Burroughs from "NIX I", an abbreviation of "Numeric Indicator eXperimental No.
