We offer optional Accessories for the Nixie Clocks:

Our Benefits:

• All our Nixie Tubes Clocks are using HV513WG chips,
  it provides higher brightness in multiplexing mode in comparison with HV5812 chip and greater reliability compared to legacy K155ID1
• We offer flexible Tubes Boards platform, that support many Nixie Tubes
  (out Tubes Boards designed for IN-4, IN-8, IN-8-2, IN-12, IN-14, IN-16, IN-17, IN-18 and Z573, Z5660M, ZM1042, Z568M Nixie Tubes)
• It is easy to build a beautiful Nixie Tubes Clock with our Boards, we also offer Acrylic, Wooden and Stone Cases for our Clocks
• Fast uploading pf the Firmware via USB to the Control Board
• All the latest version of the Firmwares to all our Nixie Clocks are always available on our GitHub channel
• No need for additional drivers, we are using only genuine USB-to-serial converters (FTDI),
  drivers for them are pre-installed in all popular OSes: Windows, MacOS, Linux
• It is easy to modify the Nixie Clock’s Firmware functions for your tasks due to the open Arduino platform
• We use High Quality PCBs and Components, also we use Japanese aluminum capacitors only for our Boards (Nichicon, Panasonic)
• Tubes Board is easy to modify by cutting if you want to build 4 Tubes Clock [HH:MM] from 6 Tubes Clock
• Our Nixie Boards use Power On Self-Test (POST): LED backlight flashing,Tubes flashing and Start up Tune. Our Boards use,
  Firmware version can be seen at the end of the POST test
• Our Tubes Boards use Unique detailed Tube test – our soft test checks each Tubes segment on every Tube so it distinguishable to see segments failures
• We provide competent technical support for all our products

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 change it (included songs: Mission Impossible, We Wish You…).
• Easy updating firmware via USB using Arduino IDE.
• Software is 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.
• Tubes are installed in sockets, therefore can be easily replaced.
• 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).
• High quality PCB and components. We use Japanese aluminum capacitors only (Nichicon, Panasonic).
• 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.
• 2 dots Column (digits separator) with independent controls for upper and lower dots.
• Power consumption: 11-14V, 360mA (Recommended: 12 VDC, not less than 1A ).
• NCM109 MCU board size: 100 x 50mm (world’s smallest dimension).
• NCT408 Tubes board  size: 200mmx50mm

*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, IN-15, IN-16, IN-17. To use these Tubes, you need appropriate PCB for tubes.
