New nixie tube watch…

Nixie Watch Redux by Jeff Thomas…via Tube Clock database.

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.”


Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.

  1. It is huge compared to a normal size wristwatch. Yow.

  2. hi barry, it’s smaller than the watches we wear 🙂

  3. It’s interesting. Being taller than wider, a possible workaround to the size would be to mount it sideways, this is, to view the time one must show oneself the side of the hand instead of the back.

  4. I like it, thumbs up form me.
    it would be better as a pocket watch or a brooch.
