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?"

Features

  • Only analogue technique is used.
    The measuring electronics runs without any processor or other digital ciruity.
  • Power supply via USB port.
    Power consumption is as less as NixieTherm RGB can powered up from a simple USB port. No driver needs to be installed. NixieTherm only "catches" the supplied voltage. As an alternative, NixieTherm RGB can be powered from a standard Mini-USB charger.
  • Low power consumption and self heating
    50...400 mA @ 5VDC depending on the lenght of the glow coloumn thanks to the high efficiency voltage doubler in the HV supply.
  • High accuracy with LM35DZ temperature sensor
    +/- 1°C (+/- 2°F) adjustable.
  • Displayed temperature range
    10...30°C / 50...86°F
  • Fully smoothed display
    in true realtime.
  • Easy operating the RGB controller
    by pushing a simple button
  • The electronic kit:
    You get a complete electronic and mechanic kit – and complete means complete:
    • All electronic parts + PCB with assembled and soldered SMD parts
    • All mechanical enclosure parts
    • USB power supply with mains plug for EU/US/UK on request
  • SMD pre-assembed
    Thanks to the most SMD pre-assembly and soldering only a small handful parts needs to be fitted and soldered.

What you'll need:
  • Around 2 hours of your evening time with no hurry
  • A clear, well-lit area in which to work
  • Soldering station with fine tip and fine electronic solder
  • Multimeter to check the generated voltages
  • Electronic tools
  • TX10 (Torx), PH1/2 and slotted screwdriver
  • Download of the manual
  • Enjoyment of your work of course
  • And last but not least a simple USB port on your PC or a Mini USB charger to power up NixieTherm RGB.

The Story behind the NixieTherm

The original NixieTherm Mk I was introduced in 2011 (Download Design Protection) and were sold in the meantime more than 1000 times.
Thanks to the SMD pre-assembly only a few components needs to be fitted and soldered manually for an easier and faster assembly pleasure.

Imitation is the sincerest form of flattery...

In the meantime there are a lot of cheap copies - specially from Lithuania, Ukraine and - with faked accounts now also from Italy - on the market, but they have never reached the top quality of the German original Mr.Nixie's NixieTherm.
