Tito] entered a Self-Charging LED Flasher into the Component Abuse Challenge. It’s a simple re-build of a design by the ...

With this circuit you can flash some LEDs for your rc airplanes or any other uav just like the real strobe navigation lights of an airplane, using the service provided by jlcpcb you can order the ...

Let’s say you want to blink an LED. You might grab an Arduino and run the Blink sketch, or you might lace up a few components to a 555. But you needn’t go so fancy! [The Design ...

This is a simple flashing led circuit with 2 leds and 2 NPN transistors. It illustrates the behavior of transistors and capacitors and if you use an oscilloscope it will be very easy to determine what ...

The flashing is thanks to LEDs with a built-in, integrated flashing circuit and the nasty noise comes from a piezoelectric buzzer — both are available from electronics stores that sell ordinary LEDs.

I was puzzling over the classic bistable circuit and wondering if it was possible to expand it to any number of channels. And this is what I came up with. BTW: To make it more interesting (claims I), ...
