Plug-able USB Powered-Li-poly battery drive-able ,Two-Digit IN-18 NIXIE Tube Clock-Pro.

Plug-able USB Powered-Li-poly battery drive-able


Two-Digit IN-18 NIXIE Tube Clock Pro.


New design, by using two In-18 NIXIE tube to display the Time/Date/Temperature


*Improved the HV circuit,small size,high Efficiency.You get almost no heat under 24*7 working condition;


*Improved the RTC rechargeable battery,now can last over weeks when fully charged;

*Improved the software,add self power on testing function,add [FLASH] switching effect;

*Can install Li-poly battery charging circuit(optional), thus you can light the clock up by using the Li battery;


Tube Name:
IN-18 (Made in the U.S.S.R.);
Tube Size: 30mm(dia);

Tube Height: 68mm(no including the legs and the glass nipple);
Digit Height: 40mm;
Digit Width: 22mm;

Clock Supply: 5V DC via MINI-USB;
Working Current: ~450mA;(~850mA in Li-poly battery charging mode);
Clock Size: 104mm(L)*66mm(W)*20mm(H)
PCB Size:94mm*56mm;
PCB Color: Black;
Weight:75g(weight no tube installed);
The clock works with any standard USB power supply,use only high-quality adapter!

The clock works with any standard USB supply, use high-quality adapter only!


1).5V USB powered, easy to be used. Can connect to your computer's USB plugs directly;
2).High efficiency HV circuit, you get almost no heat in 24*7 working condition;
3).All SMT components, very thin PCB, Bottom component has only 6mm(max) high; Static driving, No Blue Dot, No Flashing, High Brightness;
4).Support 12H or 24H display modes, can show "." as "A/P" in 012H time format. Leading zero blanking is programmable;
5).Display date in all format: YY.MM.DD or DD.MM.YY or MM.DD.YY or even MM.YY.DD; Can display week info too;
6).Support 5 different Effects: Normal/ Fading/ Cross Fading/Slow Fading /Loop/Flash for displaying time. All the segments in the IN-14 tube can be lighted up, include the Left & right dots;
7).High accuracy RTC inside, factory calibrated to ± 5ppm, ±13 seconds (Max) per month;
8).Simple setting by using 2 buttons only and supports IR remote control (optional) ;
9).Three alarms with weekends ON/OFF support can be controlled individually;
10).Three programmable Auto Power ON/OFF mode, can turn ON/OFF NIXIE tubes in any time you want. This function can save tubes life;
11).8-level adjustable NIXIE tube bright with Auto-brightness feature (it is able to adjust the tube brightness depending on the current environment);
12).Rechargeable Backup Battery or Farad capacitor keeps RTC running during power outages;
13).Tri-colored RGB LED mounted under the each NIXIE tube. These LEDs can display different colors with a lot of pre-defined auto color change effects.
14).Store user settings in non-volatile memory;
15).CAD designed acrylic case made using a laser cutter makes the clock look beautiful. You can assemble/disassemble the case by using only 4 screws on the bottom of the case. The case also has 4 bumpers as feet on the bottom of the case in order to stop to prevent case's damage;
16).Can install Temperature Sensor(optional) ;Can install Li-poly battery charging circuit(optional),thus you can light the clock up with Li-poly battery only;
