The “two flashing led” circuit is designed for 9 Volts but it works at lower voltages too. In this design we used red leds but by changing the series resistors R1 and R4 you can also use different LED ...

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 ...

With this circuit you can flash some LEDs for your rc airplanes or any other uav just like the real strobe navigation lights ...

This is a very simple but useful project, strobe navigation lights for rc airplanes, or you can adjust the flashing time and ...

[Collin] demonstrates this technique in the video, constructing a simple LED flasher circuit. He says that the process works decently enough, and was kind of fun to do.

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 ...

Even though there are other ways to blink a LED and other ways to make an oscillator, [Eric]’s circuit is about as simple as it gets. [Thanks, fede.tft] ...

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

Note the addition of Schottky diode D1 in the active-low circuits. Although the inputs are protected against negative-going spikes, the positive input spike that occurs when the output returns ...
