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

Two-Digit IN-14 NIXIE Tube Clock Pro.

New design, by using two In-14 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;

*very thin PCB,the MAX height equipment under the PCB is the 6mm*6mm button;

*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-14(Made in the U.S.S.R.)


Tube Diameter: 18mm;


Tube Height: 55mm (approx including glass nipple);


Digit Height: 17mm;


Digit Width: 10mm;




Clock Supply: 5V DC via USB;


Max Current: ~200mA(~500mA in Li-poly battery charging mode);


Clock Size: 68mm(L)*50mm(W)*70mm(H)(with IN-14 tube installed);


PCB Size: 58mm*41mm;


PCB Color: Black;


Weight: ~60g;


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;

    I am curious to know if you could assemble one of these with the capability of driving Burroughs B6091 tubes? Is it as simple as changing the anode resistors? I am aware of the pin out difference and would be installing cables and sockets myself. I would not need the socket pins that you typically install, a plastic case or tubes and would also like the temperature sensor to not be installed but shipped with the clock so that I may install it remotely, myself. I can provide you with datasheets if needed.
    Thank you for your time,

    To Up:
    For design only one clock will cost a lot of money ,not worth,we recommend you just buy one IN-14 2-tube clock directly and connect it with your different tubes via wires by yourself to see if it fits your requist,usually for the B6091 you even do not need to change the resistors on anode.
