Decorative object with IN-19 nixie tube
Nixie Tube Ornament is stylish decoration for your home, office or shop, also suitable as an original gift or night light. You and your friends can enjoy retro look from beautiful IN-19 nixie tube light.
IN-19 (original name ИН-19) is symbol nixie tube originally manufactured as complementary tube to numeric IN-14 tube. This nixie tube was intended for displaying of units or special symbols in combination with numbers and used mostly in old measuring devices. There are 3 different symbol set types:
All symbols of this nixie tube are periodically displayed with dimming effect and adjustable speed. Nixie tube is backlighted by RGB LED, what allows creation of beautiful optical effects in tube glass. In addition all setting changes can be done without using of any tool, but simply by three control buttons.
|Input voltage:||5 – 10V DC|
|Dimensions (W x D x H):||60mm(2.36") x 60mm(2.36") x 64mm(2.52")|
(For details please see "Powering Up" section)
|Backlight mode setting:||backlight mode can be changed by “LED Mode” (middle) button. There are 3 possible backlight modes available – backlight disabled, automatic color change, manual color change.|

|Manual color change mode:||backlight RGB LED is enabled, light color is not changing, but can be set manually.|
Nixie Tube Ornament should be powered from any USB power charger 5V/850mA DC or more.
The power source adapter/charger and USB mini B cable are not included in the package, since we assume that most of our customers already have some charger at home.
Please note – if you decide to use less powerful power source, we cannot guarantee that this will provide enough initial current to power up the Nixie Tube Ornament. Even though, normal operation requires 150mA at maximum, but initial powering-up of the power supply of Nixie Tube Ornament requires higher initial current (during the current peak). Therefore, It is highly recommended that you use USB power adapter/charger which has 850mA (5V) or more.
Powering Nixie Tube Ornament via your computer’s USB port is not recommended, because initial current peak can harm your computer’s USB port.
Initial Version 1.0 - Prototype
First of all there were defined properties and behavior. Prototype was based on development board with Cortex-M0 and Z560M nixie tube. High voltage for powering of nixie tube was provided by HV-PSU_KIT module.
Video below shows base functionality - setting of nixie tube characters chnaging speed with diming effect and malual setting of RGB LED color.

First Version 1.1
Once the prototype was successfully created and tested, it was necessary to try complete circuit on own printet circuid board. As outcome of this necessity is Nixie Tube Ornament Version 1.1 with these features:
Version 1.2 - Corrections
Printed circuit board of version 1.1 was not fully functional and contained several mistakes, so redesign was needed. Newly created version 1.2 was correct and fully functional.
After presentation of such result to one of my friend, I decided to postpone the release and improve few features.
Main points were:
