  • Getting power from wall plug power supply means your clock is isolated from the main
  • Clock works from 7.5 to 12V DC, but 9v supply is recommended and is optimal choice
  • Power consumption:
    2.6W (280mA@9V) from wall plug power supply (all 6 digits to display)
    2.3mW (0.75mA@3V) from backup battery ( 3V CR2032).
  • When Clock powers up from backup battery, it does not display any information, but keeps running and activates buzzer in Alarm1 or Alarm2 events.
  • To keep backup power consumption at low level, do not connect load < 100 kOhm to the external alarm contacts.
  • Internal buzzer generates simple two tones and pause sound in Alarm1 or Alarm2 events. It will last for 1 minute, but could be shut off by pressing the button.
  • External alarm contacts set logical "1" in the alarm event and gives you extra feature allowing to connect quality sound melody generator or any external modules via appropriate converter or power control circuit (not included in this sale).
  • Frequency Test Mode can be activated to easily check and adjust clock frequency. In this mode Clock does not display or keep time and date, it only displays 200000, which means 200KHz frequency signal is activated on the dedicated output pin. Use it to check it, if you have calibrated precision frequency meter or use this signal for your calibration purposes.

  • First Class Signed For Royal Mail delivery. Just small extra delivery charge to post it to Europe or to the USA, Canada.
  • Your Clock will be fully tested, calibrated and well packed before I dispatched to you.
  • I'll dispatch your Clock on the next working day after I receive your payment.

  • Digit height - 18 mm.
  • 2 PCB boards, each - 50x170mm
  • Nixie clock, including IN12 indicators and button tips - 50x170x60mm

Extra words about Clock and its design

  • Congratulation! as you reached this point reading my item sale description.
    It means you are interested in my Nixie Clock and hopefully you are considering to buy it.
    Below you can see my thoughts, which I hope answer your remain questions
    and will help you to put your bid on!
  • I designed just NIXIE CLOCK ! It doesn't have integrated MP3 player, It will not freeze or cook your food, as it does display Time and Date only.
    Sorry, but no movies or pictures can be viewed or downloaded and stored there from your digital camera or camcorder! No square root or estimate arrival time can be calculated as well!
    It's not health care or military device, it will not calculate the Nixie Tube's or internal components life time either.
    This clock is just simple, elegant, reliable and easy to use device !
  • This clock is fully assembled, tested and calibrated. Just spend your time and efforts to create the case, which you will love!
  • You don't need to have special electrical or electronic education. This clock is very easy to connect and simple to use.
  • In this Clock I use static digit indication. It means that the digit is not flickering with 50Hz or any other frequency.
    So it's static until it changes to other value to display, then it's static again.
    It is much better for your eyes; clock consumes less power, creates less electro-magnetic fields around.
  • I will not implement Remote Control feature in my Nixie Clock. Why?
    I think, it's really useless and absolutely un-efficient! Why do you need Remote Control if you should set or correct the time only once a year.
    Alarm time? Again, how often do we set Alarm time? Several times per day? I don't think so. Usually we do it very occasionally! How many Remote Controls do you have at home? Do you really need one more?
    Will you find it in 6 months or 1 year? ;-)
  • Looking at another available Clocks on the market, I can say, that only a few Sellers says about their Clock Power consumption, its dc/dc converter efficiency, but I DO ! I think it's important to know how much energy your Clock will consume, as It should be connected 24 hours per day, 7 days per week !
  • Almost nobody specify their Clock accuracy. I can see only general phrases like "accurate, very accurate...", but again - no specific information! I DO state, that my Clock have not more than 1 second error in ONE week ! It means less than 1 minute per YEAR ! To archive it I do not use Radio or GPS modules. So you do not need to spend extra money to buy it. You don't need to bother where to locate your GPS receiver to get good signal and how to hide extra wires !
  • Why do I not sell the clock kit ? The clock kit is great , when you wish to assemble somehing yourself, as well as it's not difficult to follow the guide how to do it. But when you built it, you need to CALIBRATE it ! Even you use good quality crystal in your clock circuit, you must adjust the internal clock frequency !
    How should you do it? You will need pre-calibrated precision Frequency Counter (of cause everyone has it! ;-) ).
    If you do have it, just connect it to special 200kHz frequency Test Point, set Clock to Frequency Test Mode and adjust frequency using trim capacitor on the board.
    But If you don't have good Frequency Counter, I am sure, soon you will be disappointed with you clock accuracy. Inaccuracy could be several seconds per DAY! That's why I do calibrate every clock I sell to you!
  • Only my Clock has dedicated output to check the internal clock frequency !
    Why do we need it?
    a) Calibrate your device like another Clock or Frequency Counter. It's very useful option, if you are radio electronic fan and doing some projects, which would require accurate clock or precise frequency.
    b) Calibrate your Clock. We must calibrate the Clock, otherwise the clock accuracy will be poor, even we use high quality crystal. Usually you connect your Frequency Counter directly to the crystal, but your Frequency Counter gives your internal clock an extra capacitance and the measured frequency slightly shits from the actual, so the calibration can not be precise!
    My clock has dedicated, separated from crystal output, where you can check the frequency and ideally it should be 200,000.0 Hz.
    But don't worry, I'll do it for you and your Clock will be fully calibrated to get the best accuracy!
  • I am designing the case for my Clock. It will be classic, lacquered wooden box case, perfect for classic and modern room designs.
    Personally, I don't like the clear glass cases like upside down fish tank! ;-(
    I also do not welcome the cases with unprotected Nixie Tubes, which are just inserted in clear or polished metal base.
    I think it's dangerous to leave the glass Tubes (under high voltage) unprotected (especially if you have a children at home), as it's very easy to brake it partly or completely, also it's not easy to wipe the dust !
