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 $15… ...

The 555 timer is one of the most versatile integrated circuits available. It can generate PWM signals, tones, and single-shot pulses. You can even put one in a bi-stable mode similar to a flip flop.

Used in a variety of timer, pulse generation, and oscillator applications, the 555 was designed in 1971 by Hans Camenzind. A favorite for many engineers, the 555 is still in widespread use due to its ...

Just about anything can be made with a 555 Timer, and every circuit is fun to build, which I show in my book “ Essential 555 IC: Design, Configure, and Create Clever Circuits.” ...

A common problem with on-delay timers is the timing capacitor reset. Typical timers (555 included) rely upon both complete power loss and finite elapsed time to assure that the timing capacitor is ...

He used a 555 timer that outputs a clock to the LEDs on the biz card, and placing a nine-volt battery on the terminals sets off the mini light show. See for yourself in the video below.

But the 555 just does not do anything precise, or even semi-precise, that I need done. So that's one thing I can "share" - my favorite circuit to use a 555, is: a blank piece of paper.

The finished product is a 30 times larger model of a 555 timer chip and is quite the accurate rendering. No word yet if other chips will receive the same treatment when the situation calls for a ...

Ever wanted a 555 timer with complementary non-overlapping outputs. The XTR651 from X-Rel Semiconductor is just such a thing. Very similar to the good old 555, it includes a built-in 200pF timing ...
