DIY KIT for IN-18 Nixie Tubes Clock
Boards and Electronics parts WITHOUT TUBES
UPS Express delivery is highly recommended
Economy Shipping is very slow and unreliable

Project "Divergence Meter" has modular system, so you can build Clock with 4, 6 or 8 Tubes
To build Cock with 6 Tubes you need one MCU Control Board NCM109 and Tubes Board NCT318
To build 8 Tubes Clock you need additional one Tubes Board NCT818
To build Clock on 4 Tubes you need cut the Tubes Board along the line (as shown on photo)

DIY KIT is compatible with Arduino UNO, it allows you to write your own unique programs on the Arduino platform

Software Features:

Clock support many kinds of Nixie tubes (4 tubes [hh:mm], 6 tubes [hh:mm:ss] and 8 tubes [HH:MM:SS:uu**/Temp]). ** – shows 100’s and 10’s of micro seconds.
12/24 hour format.
Date format 6 tubes: [DD:MM:YY] and tubes 8: [DD:MM:YYYY]
Slot Machine (Anti poisoning – tubes saving function. Increases the service life).
Unique RGB LEDs backlight with 16,7 million colors.
Very easy to switch LEDS off/on.
As alarm sound clock uses standard RTTTL (Nokia format) melodies, so You can easy 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.
