From simple buzzers to an Atari Punk Console, the simple 555 timer chip is the foundation of a whole lot of interesting lo-fi synth projects perfect for beginners. [Steven] put together a great ...

This project details the construction and observation of a simple crystal oscillator circuit designed to generate a clock signal around 16 MHz. The oscillator is built using a 16.000 MHz crystal, a ...

This article is part of the 2022 April 1st series in the Humor topic within our Series Library. The ubiquitous 1971 digital miracle—the 555 Timer—is important, replete with 25 transistors, 15 ...

For battery-powered circuits, it is easy to build an ultralow-current crystal oscillator designed around a 32.768-kHz crystal. This crystal is common for real-time-clock circuits. Because these ...

Since its invention over a half-century ago by Hanz Camenzind at Signetics, the familiar 555 analog timer (in league with its updated pin-compatible CMOS descendants) has become an iconic design ...

“Instead of an Arduino, he could have done that with a 555 timer.” “Instead of a 555 he could have done that with two transistors.” “Instead of a few transistors, he could have done that with ...
