Like our recent post on a DIY Metal Detector, this project makes use of the ever relevant 555 timer. Except in this case they are using a more modern TLC555 timer which only requires 3V instead of ...

The output pin is taken from a buffer to prevent interaction with other functions of the IC. An output of full power or dead ground is the only option at pin 3, so an appropriate protection resistor ...

Use a 555 timer as a switch-mode power supply; NE555 timer sparks low-cost voltage-to-frequency converter; If you want a timer function that works, Linear Tech just came out with the TimerBlox. Lets ...

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… ...

They’re asking for people to send in their craziest 555 timer-based project ideas in The 555 Timer Madness. Head on over there and submit your idea. You can win a $200 or $100 shopping cart!

This voltage-booster circuit for driving one or more white LEDs uses a 555 timer as its main element (see the figure). The timer, IC1, functions as a resettable astable multivibrator where R1, R2 ...
