Digi clock with gps time updating
Unfortunately not everyone saw that clock as the awesome creation of a teenage engineer, instead some people feared what they didn't undestand.
This project will show you that anyone can build their own clock with a few parts and a little time. One way is with a GPS receiver which allows the clock to set its time automatically.
Dedicated GPS timing receivers are accurate to better than 1 microsecond; however, general-purpose or consumer grade GPS may have an offset of up to one second between the internally calculated time, which is much more accurate than 1 second, and the time displayed on the screen.
Other broadcast services may include timekeeping information of varying accuracy within their signals.
There are a few dozen GPS satellites in orbit above the entire globe and all of them have extremely accurate clocks that make determining your position on earth possible.
By tapping in to the time broadcast from these satellites you can easily build a very precise clock.
This is a project to build a clock with an Arduino that sets itself using time broadcast from GPS satellites.
The inspiration for this project came from another cool clock built by a 14-year old and that captured the interest of the President of the United States.
This won't set itself like a GPS clock, but it will keep good time for many years. The best part of this project is that you can build it yourself exactly how you desire.
While things aren’t quite so extreme down here on present-day Earth, the colonists’ sentiment, that nothing is really free, still applies to a lot of things.
There may not be such a thing as a free lunch, but there is such a thing as free time clock software.
I still have my old Garmin Forerunner 110, which automatically updates time and date every time I use it outdoor, so the technology to this in a watch have been present for years...
Will it be possible to get this feature in a Tom Tom watch in a future firmware update?
