One of the most common clichés around here is that a piece of equipment chosen for a project is always too advanced. If a Raspberry Pi was used, someone will say they should have used an Arduino. If ...

The 555 timer IC has been reinvented—again. Signetics introduced the enormously popular chip back in 1971, and it quickly became a big hit. Myriad application circuits have used it throughout the ...

Editor’s Note: Hans Camenzind was selected for the Engineering Hall of Fame in our inaugural induction, which appeared in our 50th Anniversary issue in 2002. He died on August 8, 2012. His son, Peter, ...

This stunning piece of art is [Emily Velasco’s] take on the Atari Punk Console. It’s a freeform circuit that synthesizes sound using 555 timers. The circuit has been around for a long time, but her ...

As 555 timer is robust, stable and most commonly used IC in the area of electronics and also use in many electronic circuits. This post gives an idea about 555 Timer IC pin diagram and its description ...

When you first clamp your hands, mic detects the sound and triggers the 555 timer via the operational amplifier. The timer stretches the signal and applies it to the clock input of the flip-flop.

Semtech has introduced an analogue timer chip that runs from 0.9V, but can drive LEDs at over 3V. Called SX8122, to the timer it adds: a simple battery charger, a boost converter, and a power-down ...

As the tired old saying/meme goes, necessity is the mother of invention. The necessity in this particular scenario was a dire need for a foot stool. The mothering of course involved a very unique ...

Today we are going to create a strobe light for the tips of the wings of an rc airplane using a 555 timer (NE 555 or lm 555 IC) this circuit is very easy to make with few components and most ...
