I had a clock that I wanted to put in my office, but I didn't want to be bothered by the ticking noise that it would make. So, I replaced the clock hands with two rings of RBGW LEDs. The inner ring ...

Any RTC module would work but the DS3231 is the more compact and reliable (I've used the DS1307) When I built this clock the 0.78 inches (high not diagonal) 7 segments display cost something like 3-5€ ...

In this article you will learn how to make a digital clock using Arduino and the DS1307 RTC IC. What is DS1307 IC actually? Well, it is a Real Time Clock (RTC) IC that is simple to use, low cost and ...

The DS3231 RTC module is a real-time clock that uses less power and has highly accurate communication via an I2C interface. Also, the DS3231 real time clock has its temperature-compensated crystal ...

Maker Michael Klements has built a unique electromechanical clock using a little Arduino hardware, code, and 28 servos, which tilt panels to reveal the correct time in digital format. As the time ...

We have featured quite a few cool clocks here at Geeky Gadgets, and the latest one is the work of Andrew O’Malley, the DOTKLOK, which is an open-source Arduino digital clock. The DOTKLOK comes with a ...

Every maker needs a geeky wall clock and the geekiest way to get one is to build your own. With so many modular and open-source options, building your own decorative clock is far from the most ...

If you’ve got an old black and white TV, it’s probably not useful for much. There are precious few analog broadcasters left in the world and black and white isn’t that fun to watch, anyway. However, ...
