The digital blue clock project is base on Atmel ATmega8535 microcontroller where the main purpose is to make a useful gift for friends and family. From the design of the device, the circuit board is ...

The circuit was constructed from a spare LCD, a 16-button keyboard, and a PIC16F877A microcontroller to create a clock based on the Mars time. The circuit was constructed from a spare LCD, a 16-button ...

We’ve seen a few Nixie projects around here before, but this one might be the simplest yet. [Pinomelean] designed this simple nixie tube clock with just a handful of components. The Nixie tube chosen ...

[fahadshihab], a young tinkerer, shared his circuit design for a simple remote control using 555 timers. Using a 555 calculator, he designed a clock circuit that would run at 11.99 Hz. Two transistors ...
