A GPS Nixie Clock is a dummy proof clock that just works. The time and date adjust according to your location. If one day you’re in the Bay Area and the next you’re in Shanghai, the clock will display the local time zone.
Goal of the project was to make a zero maintenance clock with automatic time zone adjustment.
The GPS Nixie Clock works right out of the box. It’s powered by a USB-C port (5V 1A). All the clock needs is to receive an accurate GPS signal to calibrate the year, month, week, hour, minute, and seconds.
Simply placing the clock in an outdoor open area for a minute will set the time correctly down to the second.
After the time is set, an internal RTC module will save the time ( year, month, week, hour, minute, second) internally. In an event of a power outage or a loss of GPS signal, the time will not be lost.
If the time is off, place the clock outside for a minute and the time will be recalibrate in your local time zone.
