The flasher circuits below operate on a single 1.5 volt battery. LED flasher circuit diagrams The circuit on the upper uses the popular LM3909 LED flasher IC and requires only a timing capacitor and ...

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.

LED flasher circuit 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 ...

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 ...

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.

In Figure 1, National Semiconductor's LM3710, a supervisory circuit, is configured to reduce the power consumption of a traditional LED indicator by 99%.
