If you’re looking for a 1-second time reference, you’d probably just grab a GPS module off the shelf and use the 1PPS output. As demonstrated by [InazumaDenki], though, an old quartz clock module can ...

Although ready-made real-time clock (RTC) modules for microcontroller projects are available in every online shop, an inspired electronics hobbyist would rather put together something from a few ...

The real time clock is a custom designed module based on DS1307 that comes fully assembled and pre-programmed with the current time as the clock operates in either 12-hour or 24-hour format with AM/PM ...

A showed me a clever thing, a 1Hz reference based on a quartz clock module. These are inside just about every ‘quartz clock’ and are powered by a single AA cell. Apparently, the pcb inside provides ...

Crystal devices specialist, Epson Toyocom Corporation, has developed the world's smallest real-time clock modules. The maximum dimensions of the new RTC modules, known as the RX-4571BD and RX-8571BD, ...

Reddit user Krukerfluk has created an awesome DIY digital clock using 144 x seven segment displays, combining them to create a larger LED display powered by an Arduino Nano. The small Arduino ...

You have to be pretty ambitious to modify a clock to run for 50 years on a single battery. You also should probably be pretty young if you think you’re going to verify your power estimates, at least ...

Developers, makers and hobbyists looking for a real time clock module complete with an Arduino library, may be interested in the Kraztech Real Time Clock Module created by developer Christopher ...

The maximum dimensions of the new RTC modules, known as the RX-4571BD and RX-8571BD, are just 3.4 mm x 1.7 mm x 1.0t mm. With a footprint and cubic volume that are 43% and 52% smaller, respectively, ...
