This is a kit for B7971 nixie tubes. This is a six-digit version, including the PC board, the transformer, the pre-programmed microcontroller, and the components, including the pins to connect the tubes to the board. Text can be entered to scroll through as a 50 - character message once per minute, using the wifimodule to connect to the PIC and enter the text from a smartphone.

Instructions for Nixie 7.7:

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.

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, ledcolor to set

Set up preset on/off display times - ledcolor + toggle, fast set/slow set to select, ledcolor 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 + ledcolor, 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 wifimodule board until the blue led lights 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 WifiModule connect apage, 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. Once the module automatically re-connects to wifi, refresh the display by pressing fast set & slow set simultaneously, and the message will be displayed on seconds count 43.
