MADE IN THE USA This is the assembled kit for the B7971 nixie clock, NOT including tubes. This board is for four tubes, please select the option for the six tube board. Fully assembled & ready to "plug n play", does not include tubes. The examples with tubes are only to illustrate what the clock looks like when tubes are plugged in, this item includes everything assembled but does not include the tubes. For the unassembled kit, please see my other listings. A demo can be viewed here. A quick demo here. Text message demo here. 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 for B7971 nixies with RGB led lighting. The enclosure is plexiglass, homemade from 1/8" & 1/4". This kit is assembled but does not include the tubes.

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.

Outside dimensions are about 12" W x 6" H x 4" D.

Date display option scrolls across in MM/DD/YY format every minute on seconds count 43-59. Optional date in EURO format as DD/MM/YYYY All settings (selections) are stored in EEPROM memory, will be retained if power is lost. User programmable sleep/wake function, to turn the display on/off at preset times, in order to conserve tube life. Text message up to 50 characters (including white spaces) can be entered and displayed in scrolling format every minute instead of date option. (wifi connection only) Time zone can be selected, buyer's time zone set to default. Made entirely from repairable/replaceable parts, IC is socketed for easy replacement. GPS / WiFi module enabled automatically sets time & date. 12 / 24 hour format options with or without leading zero. Option to set daylight savings time to on/off/auto Option to set for 120VAC (USA) or 240VAC (some other countries) Auto detects and set for 60HZ (USA) or 50HZ (some others) Instructions: Refresh time from network - fast set + slow set Select time, date or text display - fast set + ledcolor, slow set to select, toggle to set Twelve or twenty-four hour clock format - fast set + toggle, slow set to select, led color to set Set up preset on/off display times - led color + toggle, fast set/slow set to select, led color to set/move to next screen Select time zone - slow set + toggle, fast set to select, slow set to set Select DST on / off / auto - slow set + led color, fast set to select, toggle to set To enter text message (up to 50 characters, including white spaces), press and hold the "reset" button on the wifi module board until the blue led lights up on the board (not the one on the chip that blinks) Go to your networks on your device and connect to the "WifiModule" network, as when setting the module up initially, but instead of hitting the Wifi Module connect page, instead type the address - 192.168.4.1/TextInput This will pull up the text input page where you can enter the text message and hit "Submit" button on the page.
