It’s back! The 555 timer contest wants to see you do something cool with the 555 timer chip. At stake is the adulation of electronics geeks everywhere. Three top winners will be awarded a $150 ...

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 ...

In this article you will learn how to build an optical theremin using a 555 Timer IC. You will learn the functions of the pins on the 555 chip that are used in this build. You will learn that when the ...

Semtech Corp announced a sub-1 V analog timer platform that revolutionizes the conventional 555 timer for low-voltage, battery-operated small appliances. Semtech Corp. announced a sub-1 V analog timer ...

Most switch-mode power supplies rely on a PWM (pulse-width-modulated) output that is controlled via voltage feedback. A 555-timer IC can inexpensively perform PWM. The circuit in Figure 1 shows how to ...

Here’s another fun weekend project for the hacker younglings, a musical synthesizer that plays different musical tones based on the resistance of your conductive graphite drawing! Like our recent post ...
