Finally!...A brand new design with all new options...The ultimate Nixie Tube clock...the "Nuova Era"


Nixie tubes were believed to have been first introduced in 1954 by the Burroughs Corporation USA. They were known by other manufacturer names such as “Numicator” - but “Nixie” soon became the most popular. (“Nixie” is apparently an abbreviation of "Numeric Indicator eXperimental No. 1").

As technology progressed, Nixie tubes were gradually replaced by LED displays in the 1970s mainly because they did not need a high voltage to function.
Most Nixie factories phased-out production with the exception of Russia, where they continued making them until the early 1990s.

When nixies were in production, they were expensive items even then, and were mainly used in scientific and military equipment or early calculators.
Recent interest in their retro appearance has resulted in them being in demand by collectors and clock builders. Some very large or rare tubes can fetch ridiculous prices at auction.

The IN-14 tubes used in this clock were produced by the Russian Sovtec “Reflector” factory.
They are interesting because of their use of an upturned “2” for the digit “5” (saving on production costs). Nixie tubes have a finite lifetime – it is lowest when they are driven to the manufacturers absolute maximum brightness specification – as was the case when they were intended for industrial use in brightly lit rooms. However, this clock design drives them at a much lower brightness level and has various dimming and tube switch-off features intended to extend their lifetime. It may considerably extend the expected lifetime of some nixies when used in clocks.


• The core of the clock is a Microchip PIC 16f876A 8-bit CMOS microcontroller IC. It is programmed entirely in assembly language code. It drives the nixie displays in a 2*3 line multiplex which provides fast display refresh,lower driver chip count and reduced power consumption.

• Normal clock timing is provided by the cpu crystal which can be finely adjusted using the pushbuttons and stored in EEPROM memory. Alternatively, the clock can derive timing from the 50 or 60Hz mains frequency (provided an AC power adaptor (Wall wart) is used).

• It has the option to connect to MSF (UK), DCF (Europe) GPS time receivers or a Windows PC to obtain accurate time and date updates. Or have the time increment under the control of an external 1pps time pulse. An “experimental” WWVB option is also provided – (see the time sources manual)

• The high voltage for driving the nixies is controlled and regulated directly by the microcontroller using Pulse Width Modulation. The voltage is continuously monitored and regulated. It can be finely adjusted if desired using the pushbuttons and stored in EEPROM memory – no need to fiddle with variable resistor controls.

• All clock option settings are easily adjusted using just two pushbuttons and are retained in the controller EEPROM memory during power-off.

• The clock is fully configurable with over 30 main options - scrolling date effects, digit crossfading, digit cycling, manual/timed and optically controlled dimming, Colon neon controls, AM/PM indication,12/24 hour mode, leading zero blanking etc. etc. You can even configure it to switch-over to a completely different saved configuration at the touch of a button!

• Selectable time zone – The clock can offset the time received from MSF/DCF or GPS sources by up to +- 14 hours.

• Has 6 bright tube illumination LEDS (Either Blue or optional UV (Purple) which can be dimmed along with the nixies and configured to be continually on/off or switch on or off during date display etc.

• Dimmable neons for colon display – these can be controlled in various ways to be on/off/flashing or indicate AM/PM.

• A “decimal point” type nixie AM/PM indicator which is configurable and dims.

• Because it is powered from a low voltage, It can be used worldwide (with appropriate adapter)

• Has a user re-settable tube hours usage counter.

• Configurations can be easily reset back to defaults should you wish to.

Case construction is hand made of solid oak hardwood with a beautiful cherry finish topped off with several coats of clear lacquer. The top is made of thick black polished cast acrylic plastic. There are four soft plastic feet to protect your furniture. Measures 7 1/2" long x 4 1/2" wide x 3 1/2" high.

In the Box:
AC power adapter for North America (other countries models available on request)
User Manual
