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 ...

If there is an incandescent bulb somewhere in the circuit that you are trying to flash, a standard flasher unit may work on rare occasions. The fix for this problem is installing a "no load" LED ...

I remember making a flasher with a LM3909 back in the late 1970s. It was very efficient. In regards to this circuit, I can think of one that is even simpler, although not so stable.

He discovered parasitic circuit formed by the neon switch backlight lamp (equivalent of the current source in here) and by the LED rectifier capacitor. LED’s switching converter starting point acts as ...
