IN-18 Nixie Tubes Clock in a Synthetic Granite Case. Only Case and electronics without the Tubes. Nixie Clock in a Synthetic Granite Case. Developed for 6 IN-18 Nixie Tubes, one of the biggest Vintage Nixie Tubes in the World. Nixie Tubes Clocks are one of the most beautiful and popular Vintage Clocks. IN-18 Tubes are one of the biggest mass-produced digital Nixie tubes. Clock based on MCU (microcontroller unit) flashed with Arduino Uno Bootloader and sketch (Firmware). Clock compatible with Arduino Uno, so it allows you to write your own unique programs on the Arduino platform. Latest sources are always available on. Github at the “NixeClock” repository. PCB Design Schematic Case and Software made by GRA & AFCH. If you have ANY questions, PLEASE ASK us. IN-18 Nixie Tubes Clock in a Synthetic Granite Case by Gra & Afch. Nixie Tubes Clock in a Synthetic Granite Case. Columns with Dots – 2 pcs (included with the Clock). Temperature sensor – 1 pcs (included with the Clock). Power Supply 12V/1A [US/ EU/ UK/ AU] (included with the Clock). User Manual on vintage-style paper. Power Supply is included with the Clock. Nixie Tubes DOES NOT included with the Clock. Clock uses the biggest Nixie Tubes IN-18 – 6 pcs. Date format: [DD:MM:YY] or [MM:DD:YY]; 12/24 hour format: [HH:MM:SS]. Slot Machine Anti poisoning – tubes saving function. Increases the service life. Unique RGB LED backlight with 16,7 million colors. Possible to choose any constant color off backlight LED and memorize it. Or you have option for a cyclic full spectrum. 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 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. Distinguishable to see segment failure. High quality PCB and components. Clock use 12 V/1 A Power Supply INCLUDED in package. Working on 100 – 240 VAC input. You can choose between: US, EU, UK, AU plug. Dimensions: 340 mm x 97 mm x 112 mm (13.4 in x 3.81 in x 4.4 in). Weight of the Clock with Tubes: 1,7 kg (3.74 lbs). A special socket for each pin IN-18 – 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. Very high quality of Printed Circuit Boards. Photos of Nixie Tubes Clock on IN-18 Tubes by GRA & AFCH.
