ENCI Nixie Clock

I first saw this clock come across the NEONIXIE-L message board in mid August.  From the second I saw this clock I knew I had to feature it here.  Most nixie clocks take a definite shape: a brick for a base and side view tubes mounted vertically on top.  Not this one.  End-view tubes are significantly less common and I have never seen a clock that has sixteen tubes (GN4 by ITT).

As much as I like the display portion of this clock, it is worth mentioning the quality of the build.  The aluminum chassis looks like something HP would have made.  The device looks like it belongs in some laboratory; I love it.

Topping off the features is a remote LCD display that also displays the date and time.

I won't take all of Enci's content; you'll have to visit his site for more information.  I am featuring these images and description with his permission and encourage you to go check out his site.  If you like his work, leave him a comment.

t.1972 Nixie Clock

While browsing through eBay, this clock jumped out of the hundreds of thumbnails on the screen. This is one of the very few nixie clocks that actually takes a hanging form factor.  I can only think of one other design that was intended to be hung on a wall and this one looks significantly better.  Of course, there is a catch.  This comes as a kit and you need to assemble it.  However, for $179, it is still a great deal.

From the auction:

The hardware is an single-board PCB.It has an own switching power supply, two nixie drivers(74141) a high precision crystal and a PIC-microcontroller on board.It is supplied by a 9V AC 5.5mm jack.

The Software in the version V4.0 F is very easy and confortable controlled by only one button. That means you setup the clock and correct the speed of the crystal by following a menu with only one button.

You can choose between date-mode or time-mode (in date-mode only the to neonbulps bolow glow in time mode the four neonbulps are blinking(with fading). All events in the calendar such as leap years are considered.

The very special and new thing is the FADING  of the nixie-tubes and neonbulps. That means  that the ciphers are not only digitally switched but faded in change from one digit  to the other. For example the "5" disapears (gets dark) and the "6" appears (gets bright).

This clocks are intetionally not radio controlled, because then you could not use it in any place and the recievers would disturb the clear design of the clock  For a very high precision the clock's crystal can be trimmed by the software.

Chronotronix V600-NT Nixie Tube Clock

This is the latest creation from Dieter Wächter / Nocrotec and it is based off of RFT Z5660M tubes.  There are two version of this clock listed on Nocrotec: V600-NT and the V600-RT.  The NT is the one for sale and has the "nipple top" whereas the RT version has the rounded tube design.  I believe the clock has a buy it now proce of around $800USD but since bidding has started, I cannot find the price.

As usual, Dieter has done a great job of documenting the design and building of this clock.  You can see all of the details here:


  • Fading digits (see video)
  • Stainless Steel Case
  • Directly driven display


v600 tubes


From the auction description:


This Nixie clock combines nostalgic Nixie tubes with innovative circuitry in a nobly stainless steel case. Its elaborate software and features, the good craftsmanship and the beautiful case make this clock a distinctive top-quality product. It's a handmade masterpiece in design and functionality.

This clock uses the beautiful Z5660M tubes with a digit height of 1.2" (30 mm) made by RFT!


Well balanced proportions and a clear geometry making up for a coherent and disciplined yet charming design. The clock is a celebration of purist elegance. The case is made of brushed stainless steel - a complimentary material for this unique Nixie clock. The surface is very shiny and reflects the orange glow of the Nixie tubes - you won't be able to take your eyes off it. We will send a pair of cotton gloves along with your Nocrotec V600-NT Nixie Clock in order to avoid leaving fingerprints on the case. Please wear them whenever you touch your Nixie clock.

The Nocrotec V600-NT Nixie Clock uses a state of the art circuitry. Time is kept by precise real time clock. It's accurate to within 0.0003s per minute. Nixie tubes require a high voltage to operate. In Nixie clocks there are different techniques used to generate this voltage. The Nocrotec V600-NT Nixie Clock uses the most innovative power supply we are aware of. It is a highly efficient, super low noise switch mode power supply in a very small shape (inside the case of course). The clock is not multiplexed, but the 6 Nixie tubes are driven directly.


This clock uses the beautiful Z5660M made by RFT! A popular tube with a great digit height of 1.2" (30 mm). The shape of the numbers of the Z5660M Nixie tube has been considered to be one of the most beautiful ever made. Long life and stable operation are the benefits of these tubes.

  • Leading zero suppression: The leading zero can be blanked or shown
  • Cross fading: different modes to fade the digits from one number to the next
  • Alarm clock
  • Power down mode: tubes and supply can be totally switched off for a user programmed period in order to save energy and increase life expectancy of the tubes
