This circuit was designed to provide that continuous light lamps already wired into a circuit, become flashing. Simply insert the circuit between existing lamp and negative supply. Especially suited ...

These days, if you want to flash some LEDs, you’d probably grab a microcontroller. Maybe you’d go a little more old-school, and grab a 555. However, [Jacob] is even more hardcore than that, as ...

This simple Mock Flasher LED simulates the indicator of a sophisticated Alarm system. It can be placed in doors, gates and vehicles to confuse intruders. The circuit is too simple using a Unijunction ...

Have you tried your hand at circuit sculpture yet? Well, if you were waiting for the ideal first project with a great build video to go along with it, keep reading. [4dcircuitry]’s 555-based flashing ...

Three new Star Simpson’s Circuit Classics boards have arrived at the Adafruit online electronic store in the form of the Dual-LED Flasher, the Stepped Tone Generator, and the Bargraph Voltage ...

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.

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 ...
