AC mains operated single LED flasher circuit, built using the popular CMOS timer chip TLC555 is shown below. The whole circuit is powered directly by the grid supply of 230VAC through a capacitive ...

Evil Mad Scientist Labs brings us this easy to make LED blinking circuit. The idea is to put a LED in series with a small blinking incandescent bulb from a string of Christmas lights. The bulb has an ...

This time, I will try to run and debug the LED blinking using the Raspberry Pi Pico 2 and Raspberry Pi Debug Probe provided by the Raspberry Pi development team. I will use Ubuntu for building and ...

Many portable appliances and other products that must operate from a single cell are restricted to working at very low voltages. It is thus difficult to drive white LEDs that typically have a forward ...

They look for all the world like any other LED, though embedded in the plastic dome is an integrated circuit to do all that flashing work. There was a time though when a flashing LED was something of ...

This is a very simple but useful project, strobe navigation lights for rc airplanes, or you can adjust the flashing time and make it a warning light for a forklift or even a turn signal light for a ...

You’ve got to see pictures to appreciate the simple ingenuity behind this lamp, which took three years of research to make. A few years ago, when LEDs first became a viable lighting element, designers ...
