It’s a relatively simple hardware build in that it is simply an Arduino Nano, GPS module, and e-ink display module wired together, but it provides an interesting exercise in running through the ...

Switching power supplies provide 6 V to the Arduino and 1.3 V to the filaments. If you look closely, you’ll also see a GPS module so that the clock doesn’t need to be set.

The Arduino uses latitude and longitude to help decide when to click on the lights, so it's incredibly accurate. Otherwise, the build just includes an on/off switch, a Tiny RTC, a time adjustment ...

The NeoGeo watch is created using FLORA the Arduino wearable programmable board and its GPS module to tell the time using a ring of pixels ...

You have a timer and clock in just about every single device out there these days, but if you want to build you own, Instructables user GeraldF6 shows you how to do so with a Arduino. The project ...

If you are considering purchasing a Nixie tube clock kit you may be interested in a new Arduino project published by Doug Domke to the Hackster.io website ...

Facebook has open-sourced the precision PCIe timing card it created for its servers. It combines frequencies from a miniature atomic clock and GPS receiver, both on the card, with FPGA-based ...
