Model “Divergence Meter mini”

Nixie Tubes Clock in a Clean Plywood Case

Designed for 6 IN-12 (A\B) xUSSR Nixie Tubes with Sockets

IN-12 Tubes are one of the most popular mass-produced Nixie Tubes

Nixie Clocks are one of the most beautiful and popular Vintage Clocks

Clock features Startup Tune, RGB backlight, USB port for updates

External Temperature sensor with 3.5 mm jack included with the Clock

Plugable Accessories include compact external Temperature sensor

Nixie Clock is fully compatible with Arduino platform program codes

It allows you to write your own uniqe programs for the Arduino platform

All the latest Source codes are always available on our GitHub channel

*The MCU board support a variety of tubes, such: ZM1042, Z522M, Z566M, Z5220M, ZM1040, Z5660M, B566M, LC-631; xUSSR’s types: IN-14, IN-18, IN-12, IN-8, IN-7, IN-1, IN-2, IN-4, IN-8-2, IN-15, IN-16, IN-17. To use these Tubes, you need appropriate PCB for tubes.
**4 tubes clock is available only on IN-18 (NCT218 boards), ZM1042, Z522M, Z566M, Z5220M, ZM1040, Z5660M series (NCT566 boards)

Our Benefits:

• A special Socket for each pin of IN-12 – easy to change Tubes.
• Easy to customize firmware under Your own needs, thanks to an open platform – Arduino.
• Fast uploading via USB.
• The latest version of the firmware always available on GitHub.
• No need to download drivers – we are use only Genuine USB to serial converters (FTDI FT230).
• Drivers for them pre-installed in all popular OS: Windows, MacOS, Linux.
• Human friendly menu.
• Very high qualty of Printed Circuit Boards.
• Japan alluminium capacitors.
• Power-On Self-Test.
• Competent Technical support.

Software Features:

• Clock support many kinds of Nixie Tubes (6 tubes [HH:MM:SS] and 4 tubes [HH:MM] format).
• Date format: 4 tubes [DD:MM]; 6 tubes [DD:MM:YY]; 12/24 hour mode.
• Slot Machine (Anti poisoning – tubes saving function. Increases the service life).
• Unique RGB LED backlight with 16,7 million colors. Your can choose any constant color off backlight LED and memorize it. Or you have option for a cyclic full spectrum color change!
• Switching on/off LED backlight in the matter of seconds.
• As alarm sound clock uses standard RTTTL (Nokia format) melodies, so you can easily to change it (included songs: Mission Impossible, We Wish You…).
• Easy updating firmware via USB using Arduino IDE.
• Software based on Arduino Sketch, so MCU has Arduino bootloader within.
• Power On Self-Test (POST): LED backlight, tubes and sound. You can check firmware version at the end. Unique detailed tube test – our soft check each segment on every lamp. Distinguishable to see segment failure.

Hardware Features:

• Integrated High Voltage Power supply 150 – 220V.
• ICSP connector for flashing Arduino Bootloader to blank MCU.
• 3 PWM channels for RGB LEDs 8 bit per channel = 24bit = 16,7 million colors. It can be disabled in the menu (please check the manual).
• Test points for testing, adjust and control low and high voltage circuits.
• Pads for internal buttons and terminals for external buttons.
• Pads for internal USB connector and terminals for external USB.
• Terminals for internal and external power connector.
• Terminals for external and internal buzzer.
• 4 dots (digits separator) with independent controls for upper and lower dots.
• Power consumption: 12V, 360mA (Recommended: 12 VDC, not less than 1A ).
• NCM109  MCU board size: 100 x 50mm  (world’s smallest dimension).
• NCT412 Tubes board size: 180 mm x 50 mm
