DIY KIT with boards and electronics parts for Nixie Clock on IN-18 Tubes (without tubes) Note: UPS Express delivery is highly recommended. Economy Shipping can be very slow and unreliable. Project "Divergence Meter" has modular system, so you can build clock with 4 or 6 or 8 tubes. For clock with 6 tubes you need one MCU board NCM107 and Tubes board NCT318, for 8 tubes you need additinal one tubes board NCT818. To get clock on 4 tubes You can cut tubes PCB along the line, see photo below. PCB design, schematic, housing and software made by GRA & AFCH. Set includes an unassembled board(s) - bare PCB(s), electronic parts, MCU (microcontroller unit) ATmega328P flashed with Arduino Uno Bootloader and sketch (Firmware). Kit compatible with Arduino Uno, so it allows you to write your own unique programs on the Arduino platform, the latest sources are always available on github.com/afch/NixieClock. EXAMPLE of assembled clock (glass columns (sold separately) Lot contains bare PCBs and all necessary parts (WITHOUT tubes): 1 pc of MCU board: NCM107* (If You want build your own CUSTOM nixie tubes clock, You may buy only MCU PCB). 1 pc of Tubes boards: NCT318.1 pc of Tubes board: NCT818 (for extra pay)! ( For build 8 Tubes clock) www..com/itm/182575895901 Flashed MCU with Arduino bootloader and NixieClock sketch firmware. Set of ALL needed parts(electronical, mechanical components and etc. Full list see below). User manual on vintage-style paper. Paper electrical schemes. Power supply is NOT included, buy it separatly: www..com/itm/182053434777 *The MCU board support a variety of tubes, such: ZM1042, Z522M, Z566M, Z5220M, ZM1040, Z5660M, B566M, LC-631, 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 this tubes You need appropriate tubes PCB(s). Dear customers! If you have ANY questions, PLEASE ASK us. 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 (sold separately). 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)! Nixie tubes, glass columns and power supply is NOT included!
