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… ...

Sometimes the best inspiration is limitation. The 555 timer does “one thing” — compares a voltage to a couple thresholds and outputs a signal accordingly. It’s two comparato… ...

555 timer IC design contest– no strings Learn more about the 555 timer IC design contest. AM radio made with a 555 timer IC When my buddy told me he was using a 555 timer IC to make an AM radio, I ...

In a PWM circuit, the 555 timer will output a logic signal “high” and “low” depending on a ratio derived by the value of a few components connected.

In this mode of operation, the timer functions as a one-shot. The circuit operates in the following manner. A short pulse (> 1.2V) applied to point I/P energizes transistor Q 1, pulling the 9V battery ...

Please pay Maxim whatever they ask rather than think you can cheap-out with a 555 timer. 2. Maxim s DS1233 power-on-reset chip comes in a tiny TO-92 package, as well as a tiny surface-mount SOT ...

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.

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 ...

Its design, based on a 555 timer chip, has proven itself durable enough to withstand the pressure of the heaviest feet around. Building the Chip Footstool The build started with plywood in great ...
