[Phil] has already built a few clocks with Nixies, VFDs, and LED matrices. When his son requested his own clock, he wanted to do something a little different. Inspired by the dead bug style of [Jim ...

In theory, synchronous clock multiplication is an easy task. A simple PLL with two digital dividers—one inserted just after the VCO (voltage-controlled oscillator) and the second one placed directly ...

We have seen a few of these recycled clocks here on Geeky Gadgets, made from various recycled parts from old PCs and Macs. This one is definitely one of the cooler ones. The Laser Etched Recycled ...

This accurate one-pulse-per-second clock is made with a few common parts and driven from a 50 or 60 Hertz mains supply but with no direct connection to it. A beep or metronome-like click and/or a ...

Some people can’t be bothered to read the analog face of a traditional clock. Some people cannot stand the low frequency “hum” of mains current. If you are in either of those categories, you probably ...

Clock speed is equivalent to data movement in applications that receive and process hundreds of megabytes of data each second. Applications involved in moving enormous volumes of data include cellular ...

OK, here's a little electronics mystery. I have an old (2000s) wall clock in my bedroom that I had to take apart just now because a battery leaked in it (dang Duracells....). The clock takes two AA ...
