You’d think that we’ve posted every possible clock here at Hackaday. It turns out that we haven’t. But we have seen enough that we’ve started to categorize clock builds in our minds. There are the ...

Here is a very nice project that [Znaxque] finished a few months ago: a simple nixie clock made with logic gates only. In this build, the mains 50Hz is used as a time base instead of a 32KHz crystal ...

This mind-boggling riddle that has been shared on social media is sure to leave you puzzled. We all rely on clocks daily to keep track of time, yet how many of us fully understand the workings of a ...

The project aims to build a very simple clock that does not contain any buttons, alarms, or settings besides time as it uses infrared to detect light. The IR sensor data is being read by the ...

Occasionally you might need a simple clock module for various projects. A small CMOS clock module, such as the one presented here, is not capable of offering as much precision as a clock module built ...
