Mapsevoli, Inc. ZM1040 Nixie Clock

I found this great Philips ZM1040 based nixie clock while doing my normal searches and wanted to share it.  The major features are the fading digits and the on board potentiometer for adjusting the drift / clock accuracy.  That might be a little hard to use in practice but it is a feature that I don't think I've seen elsewhere.  All of this is enclosed in an acrylic case to allow every detail of the inner workings to be seen.  The one thing that I really like above all else is the fact that the tubes are the centerpiece of this clock and not the housing.  If I had an extra $1000, I'd get one without question!

From the site:

This is a limited edition run of a professionally-made nixie clock that can utilize the beautiful Philips ZM1040 tubes. A small number of these clocks have been made by a collector who wishes to share the beauty of these tubes with the world. If you like orange, glowing digits in retro-style tubes, you won't find a more attractive clock anywhere.

The circuit board was designed by a perfectionist with an eye for simplicity and elegance. The majority of the circuit is comprised of high quality, surface-mount components with only two through-hole ICs. The clock utilizes a microcontroller for its time-keeping with a crystal oscillator which can be adjusted using an on-board potentiometer to improve accuracy. The clock software also features cross-fading so that you can watch the digits slowly fade from one to the next for a really cool effect.

Setting the time involves the simple operation of two buttons at the rear of the clock. 24-hour or 12-hour display is selectable via a jumper on the circuit board.

The clock is encased in a sturdy, custom-made plexi-glass cabinet, which displays the inner circuitry for all to see. The tubes are socketed in 84 individual steel socket pins, providing a nice retro finish.

The power is drawn from an ordinary 12V DC wall adapter. A 110V version is supplied with the clock and a 220V version is available.

The clock includes all of the following:

  • Nixie clock in plexi-glass cabinet
  • 110V/12V AC/DC wall adapter
  • Instruction manual
  • 6 ZM1040 or similar tubes (currently using Z566 tubes)

The clock case measures 8.5 inches wide, 3.5 inches deep and 4.5 inches tall. The ZM1040 tubes included measure over 2.5 inches from end-to-end and the digits are over 1.25 inches tall! The life-expectancy of these tubes is estimated to be 10 years.
