Low cost Arduino GPS clock

Former Member

Hello,

I love that youtube show.

 

 

I would like to offer an idea:

 

What about an atomic clock at home.

 

I know that would be too expensive, but what about using a cheap gps module instead to get the most accurate time possible.

 

Using an Arduino should make it possible to build and easy to rebuild for sb. like me.

 

 

I hope you like this idea

 

Regards from Germany

    -Make your own smart watch

    Your request is to use gps along with it so it updates the time. Actually you don't need a gps for a world clock. Every country has a standard time. So what you could do is instead of using gps, my idea was that Every country has a standard time and standard longitude. So you could assign values for all standard longitudes. The clock will only store greenwich(0 degrees) and display it. If you want international world time, store all the countries head time i.e. suppose you came to India, the standard longitude id 82.5. So it will be 330 min ahead.So if you want to set it to Indian std time then the current time of greenwich+330m/6 will give you Indian std time. All you have to store is greenwich time and all std longitudes*4 and store the value. Also you have to store it two categories. East and west. If it is west, subtract and if it is east add.If from India you want to store Usa which is towards west, take greenwich time-the standard longitude of USA value and you should get real time(explanation sucks). Why do it this way? You can save thickness but make sure you have enough space on the chip.
