Nixie-based tube clocks

Cosmodog's Nixie Numechron
$125 to $400

Cosmodog Nixie Numechron

Cosmodog has a great design for sale.  It is a six digit board that can support either side view or end vie tubes.  The clock first went on sale in 1998 which means that this is one of the first nixie clocks for sale.  For $125 you can purchase the board alone and for $400, you can get the board, a nice enclosure and what appear to be a nice set of IN-18 tubes.  Be sure to stop by his site and check it out.

Andrew is working on a new design for the clock which should be available in the next few weeks.  The new revision will support a built-in universal power supply to eliminate the need for an external transformer.  (I will update this post once they are for sale.)

Also worth noting, a high end furniture and home decorating company, BDDW, has incorporated his end-view design in to a few of their clocks as well.  Be sure to check out their info at the bottom of the page.

Sputnix Nixie Clock

I found this great design and wanted to share it with the community.  I really like this design - it is clean and intuitive.  Besides, it has a cool name :)  It is based on Russian IN-12b tubes that are directly driven via 8 shift register.  There are six brightness levels and auto dimming based on time is used to prolong the life of the tubes.  One other notable feature is that it also has a connection for an RS-232 interface that allows the user to upgrade the firmware without too much difficulty.  Setting the clock is accomplished using an 38KHz universal remote.  Other notable features are an on board temperature sensor and a light sensor.

Sadly, this device is no longer for sale.  I really like this design and it is one of the cleanest end-view designs that I've seen.  Greg does include schematics and firmware for download for those adventurous enough to build their own.

Nixie Watch Redux

by Jeff Thomas / $495

 

Nixie Watch Redux

Jeff has a new clock that he shared with the world on the DWF.nu forum.  It is a new design for a nixie watch based on Burroughs B4998 tubes.  It will include a rechargeable lithium ion which should last about 3 months.   The device is 41mm wide, 19mm tall, 32mm deep and weighs about 28 grams (not including enclosure).  Lastly, it will include a changing cradle for the watch.

This device also has some other uncommon features. The watch is activated by a wrist snap-shake using a magnetized ball rolling in a steel barrel.  Any unintended activations are kept to a minimum by an R/C timer circuit.  Setting the time is done with a rod magnet which activates a micro reed switches placed on each end of the logic section.  All of this is built using CMOS logic components; just like the original LED watches of the 70's. "I didn't cheat and use a microprocessor. Although I did use seven very small TSSOP packaged IC's."

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 price 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: http://www.tube-tester.com/sites/nixie/nixie-clocks/v600/v600.htm

Highlights:

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

 

v600 tubes

 

From the auction description:

JUST RELEASED. LIMITED QUANTITY!

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!

DESIGN

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.

TECHNIQUE

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.

TUBES

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.

FEATURES

  • Digit height: 1.2" (30 mm)
  • 12/24h mode
  • Date in configuration DD.MM.YY or MM.DD.YY
  • 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
  • 12VDC input voltage
  • Wall power supply for worldwide use is included
  • Time is battery buffered when no line power is available; battery will last for more than 10 years
  • User settings are always stored
  • Tubes are not soldered but mounted in sockets, that means they are easy to replace
  • Case is made of brushed stainless steel; bottom plate and all screws are made of stainless steel as well
  • Security protection against contact of the high voltage. The high voltage can not be touched also if a tube is pulled accidentally

DIMENSIONS Overall dimensions (incl. tubes):

  • 9.9" (250 mm) long
  • 3.1" (80 mm) deep
  • 3.4" (86 mm) high
