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.
See a demo of it here. An alphanumeric Nixie clock using B7971 nixies with RGB led lighting. Homemade from 1/8" & 1/4". Homemade, not a commercial product. Below are the operating instructions.
Standard or 240VAC (some other countries). 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.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. 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).
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 page, instead type the address. 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.
