More than a half-century old, the ubiquitous and mind-bogglingly useful 555 analog timer has become a perennial object for both kudus and criticism. Most of the former and some of the latter is ...

[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 ...

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 ...

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 ...

Abstract: These devices are designed to intended to generate an output signal whose frequency fluctuates with the voltage amplitude of an input signal. The basic principle behind voltage-controlled ...

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 ...
