EXAMPLE of assembled IN-18 Nixie Tubes Clock on 6 Tubes Board

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.

Hardware Features:

• Special schematic that prevent “blue spot” effect inside IN-18 tubes.

• Full static displaying mode.
• No flickering.
• High brightness.
• High contrast.
• High precision Real Time-Clock chip DS3231SN
• Integrated High Voltage Power supply 150 - 220V.
• 3 PWM channels for RGB LEDs 8 bit per channel = 24bit = 16,7 million colors. It can be disabled in the menu (see 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.
• 2 dots column with separate controls upper and lower dots.
• Power consumption: 12V, 1000mA (Recommended power source: voltage 12V, current 1-2A).
• MCU board NCM107 has world smallest size: 100 x 50mm.
• Tubes board NCT318 size: 264 x 50mm.
• Tubes board NCT818 size: 94 x 50mm.  (for extra pay)!

*The MCU board support a variety of tubes, such: ZM1042, Z522M, Z566M, Z5220M, ZM1040, Z5660M, B566M, LC-631, IN-14, IN-18, IN-12, IV-8, IN-7, IN-1, IN-2, IN-4, IN-8, IN-15, IN-16, IN-17 to use this tubes You need appropriate tubes PCB(s).
