In this post, two LED blinking circuits are given below. First one is dancing bi-color LEDs (two different color LEDs) where the two color LED will run in sequence. In the second circuit, we will ...

This is probably the simplest idea to generate flashing light from an LED using AC. The circuit is relatively the simple way of flashing one or more LEDs from a high voltage DC obtained from Mains.

With cycling safety in mind, I bought a pair of low power red LED things that replace the bungs in the end of drop handlebars. They are a neat way to get a bit of extra visibility – and to give a ...

Regular Hackaday readers will be familiar with the work of Boldport’s [Saar Drimer] in creating beauty in printed circuit board design. A recent work of his is the Widlar, a tribute to the legendary ...

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 ...

An LED is commonly used as a "power on" indicator for many electronic devices. For the LED to produce discernible visible light in daylight, the forward-bias current needs to be in the moderate range ...

Lighting a string of LEDs at a constant brightness requires driving it with a regulated current. A boost converter is commonly used to step up the voltage to a level high enough to bias the LEDs on ...

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.

LTspice is a free version of spice from Linear Technology, and it is delightfully easy to use, intuative, and seems to work rather well. Note, there is a flasher version 3 Current through component ...

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 ...

A few years ago, when LEDs first became a viable lighting element, designers rushed to cram the revolutionary technology into traditional lamps with a science-fiction gloss. Since then, designers have ...
