WIFI module included for network connection which enables automatic time & date set

and option to enter a text message which will scroll through, please see the video (50 

character maximum, including white spaces).

Can alternatively be equipped with a gps module (buyer's choice) - please note that 

scrolling text message will not operate with gps option, only wifi.

Uses all standard size components (not surface mount "throwaways") so it can actually be repaired 

as opposed to other designs.

The microcontroller is in a socket for easy replacement.

The RGB leds make it possible to produce different color lighting under the tubes, user selectable. 

Just press & hold the led color button.


An alphanumeric Nixie clock using B7971 nixies with RGB led lighting. The enclosure is plexiglass, 

homemade from 1/8" & 1/4".

Homemade, not a commercial product. Below are the operating instructions. User selected 120VAC (U.S. standard) or 240VAC (some other countries)

I will ship it anywhere in the world, but I cannot be responsible for problems and/or delays caused by 

customs in your country. 

International buyers, please send your address for a shipping quote. It is an entirely homemade 

novelty craft project from my workbench. 

Obviously, it is a novelty item meant for entertainment only, and since it is homemade, user discretion is 

strongly advised.

Instructions:

The display will show either 33:33:33 (wifi/gps enabled) or 11:11:11 (disabled)
Press fast set to select 33:33:33 (wifi, auto time set) 
Press slow set to select 11:11:11 (manual time set) 

*Note: In order to bypass the normal setup and skip loading stored settings, it is possible
to go directly to manual time set by holding "ledcolor" button at startup (plugged in) until
the display passes :12:*

**Note: To store settings in memory, the led color button must be pressed at least once,
which will change the colors. If you want to return to a color, simply continue to hold
down on the button and it will cycle through the 12 selections until you have your prefered
color displayed. This will be saved in memory as well, so all settings will return to the 
last settings before power down. ** 

Next, the display changes to either 60 (60HZ, USA)
or 50 (50HZ, some other countries)
If the wrong frequency is displayed, please unplug & power down then wait 
ten seconds and restart.

Display then changes to 12 (default 12 hour format)

 To change the date format to European DD/MM/YYYY (default is USA format):
 Unplug and power down, then plug in and when the display is "12"
 press fast set until the display changes to either "USA" or "EUR"
 then press slow set to choose one, and press ledcolor to set.
 Setup will resume from "12" and date format will be saved.

Display then cycles to 11:11:11 and may display 33:33:33 alternating to 55:55:55
while the time & date are being acquired from the network/gps signal

The display should then autoset to the correct time.
