Recreating A Popular Faux-Nixie Clock

There’s a good chance you’ve seen “Nixie clocks” on the Internet that replace the classic cold cathode tubes with similarly sized LCD panels. The hook is that the LCDs can s…

Saving A Clock Radio With An LM8562

Smart phones have taken the place of a lot of different devices especially as they get more and more powerful. GPS, music and video player, email, and of course a phone are all functions tied up in…

Simple NTP Clock Uses Custom RGB 7-Segment Displays

A great majority of hackers build a clock at some point. It’s a great way to get familiar with electronics and (often) microcontrollers, and you get to express some creativity along the way. …

Classic 1960s Flip Clock Gets NTP Makeover

Many of the clocks we feature here on Hackaday are entirely built from scratch, or perhaps reuse an unusual display type. But sometimes, an old clock is just perfect as it is, and only needs a bit …

ESP32 LED Eyes Help Keep Toddler In Bed

We’ve seen a lot of custom clocks here at Hackaday, many of which have pushed the traditional definition of the timepiece to its absolute limit. But for all their wild designs, most of them d…

The Thorny Problem of Keeping the Internet’s Time

An obscure software system synchronizes the network’s clocks. Who will keep it running?

Circuit-less PCB Featured As Faceplate For A Digital Clock

If there’s no circuitry on a printed circuit board, does it cease being a “PCB” and perhaps instead become just a “PB”? Call them what you will, the fact that PCBs hav…

Stratum 1 Grandmaster Time Server On A Budget

[Jeff Geerling] has been following the various open source time projects for some time now, and is finally able to demonstrate a working and affordable solution for nanoseconds-accurate timekeeping…

Network Time Protocol On The ESP32
