Retro Nixie Tube Clock

News

06-29-2010
New software release 1.00.11.

Fixed bug in pendulum Mode 0 which would only light some of the quarter hour lights on after a razzle. The lights are now forced on.

06-09-2010
New software release 1.00.10.

Modified the code to write the clock's sense of the time out to the rtc before each razzle (auto or otherwise). This compensates for the inaccuracy of the crystal on the RTC board.

05-29-2010
New software release 1.00.09.

Restricted the minimum time that sync time can be set to 60 seconds. Times less than that can make it hard to comunicate with the clock.

02-25-2010
New software release 1.00.08.

Modified to detect and use the RTC on power up if it's present.

Modified to detect AC or DC power and generate 60hz if DC power is detected. (This only works for 14.7456MHZ crystals).

Reduced the help messages as well as other strings to make room for the above changes.

01-17-2010
New software release 1.00.07.

Modified to have pendulum mode 0 set the lamps always on.

Modified to have the sync time to always occure at the top of the interval (an interval of 3600 will be the top of the hour)

11-02-2009
New software release 1.00.06. Modified code to calculate the current time directly from the zero crossings without converting to milliseconds first to eliminate the rounding errors that were occurring.
10-24-2009
New software release 1.00.05. The code was modified to allow advancing the minutes and hours by clicking the buttons as well as just holding them down.
The NixieNeon is a nixie tube clock designed with ring counters built using neon bulbs to allow the viewer to see the electronics perform the actual counting of time. This electronics kit offers the builder a glimpse back in time before semiconductors became inexpensive and plentiful. The Hour of the day is displayed using the twelve neon bulbs (the hour ring) circling the two 2 nixie tube digits which represent the minutes. The 4 green neon bulbs are for showing the positions for 12, 3, 6 and nine o'clock. They also blink to give a pendulum effect while the clock is operating.

Once assembled this nixie tube clock is free standing or is ready to be installed in the case of your choice. With a little imagination it should be able to be made into a nixie tube clock which can be hung on your wall. It stands 7 1/4 inches high by 7 1/4 inches wide by 2 1/4 inches deep.

Intended to be sold as a kit, the Nixie Neon has over 400 components requiring soldoring. It is sure to offer a challenge for any electronics enthusiast young or old. Completed clocks will be offered on a limited basis and may have a lead time of 60 days to be shipped.

I would like to thank my friends at Nuts and Volts for this wonderful video they made!
