NixieTherm, Nixie IN-13 tube indoor thermometer DIY kit

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 auto colour changing LEDs, which illuminate the scale from the botton, give a never ending play of millions of different mixed colours.

This is NixieTherm - The Original, first time published 2011

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 analoge technique is used
    The electronic circuity runs without any processor or other digital ciruity.
  • Power supply via USB
    Power consumption is as less as NixieTherm can powered up from a simple USB port. No driver needs to be installed. NixieTherm only "catches" the supplied voltage. As an alternative, NixieTherm can be powered from a standard Mini-USB charger.
  • Low power consumption and self heating
    50...250 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
    +/- 0.5°C (+/- 1°F) adjustable.
  • Displayed temperature range
    14...33°C / 57...92°F
  • Fully smoothed display
    in true realtime
  • The electronic kit
    You get a complete electronic and mechanic DIY kit – and complete means complete:
    • All electronic parts + PCB with assembled and soldered SMD parts
    • Tested IN-13 Nixie bargraph tube
    • All mechanical hardware and enclosure parts
  • SMD pre-assembed
    Thanks to the SMD pre-assembly and soldering only a small handful of through hole parts needs to be fitted and soldered.

What you'll need 

  • Around 1 hr 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) and PH1/2 screwdriver
  • Download of the assembly manual from www.Nixiekits.eu
  • 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 the NixieTherm.

When ordering 5 or more (assembled) NixieTherm you can get for free (!) an individual laser engraving of the scale and / or enclosure.
Please ask: Mr.Nixie@Nixiekits.eu

Here's an example

 Available colour option for this special version:

Risks and challenges

The Story behind NixieTherm

NixieTherm was introduced in 2011 and were sold in the meantime more than 850 times. Now another batch needs to be re-ordered (and pre-financed for sure) with a PCB and enclosure redesign, which means that the PCB and the enclosure are now smaller and the board is nearly fully SMD assembled and soldered. Therefore only a few through hole components needs to be fitted and soldered by the customer 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.
