Description
A Russian Bargraph-Nixie-tube shows similar like in the good old time a mercury thermometer the room-temperature with a variable glow hight lenght; however with NixieTherm you have a wonderful red-orange glow. At the same time six RGB LEDs, which illuminate the scale from the botton and are driven by PIC a controller, give a never ending play of millions of different mixed colours.
This is NixieTherm RGB - The successor of the 2011 introduced Original
It is the eye-catcher par excellence – at your home, your office or as a very specially gift idea for Birthdays or Christmas.
Oh, what are "Nixie-tubes"?
The word "Nixie" was formed from the words Numeric Indicator eXerimental No. 1 and first introduced 1954 by Burroughs Corporation from USA as a brand name for numeric displays. Nixie tubes were used until the mid of the 1970's as displays in measuring devices, calculators, TV sets and the very first computers. The evolution of modern style display types like Numitron, VFD, Light Emitting Diodes and Liquid Crystal Displays, which have a very low supply voltage (battery power supply) eliminated these Nixie tubes from the market, and they are not produced anymore. In the former USSR Nixie tubes were produced as surplus in vast quantities until the beginning of the 90's – and from this sources is this tube. But even these supplies are now running short. And when they're gone, they're gone. The tube is taken from "NOS", what means New Old Stock. They were never used before and spent their first thirty or more years forgotten in some Russian warehouse. The principle of the Nixie tubes is based on a cold cathode discharge and it is used today a million times e.g. in small neon bulbs of illuminated mains power switches.
This Bargraph tube in the NixieTherm is a special construction of such a neon bulb, it can produce a current depending variable glow hight lenght when a current regulated voltage of around 140 VDC is applied.
Often were asked: "What is the lifespan of a Nixie tube" and than there is a simple answer: "Have a look at your illuminated power switch of the multiple outlet strip. How many years does this small neon bulb lights continously without any aging issues?"
