Super Bright 3v Powered LED Flasher (April 22, 2009)
I have posted several kinds of LED flashers over the years. This is yet one more flasher, designed to flash any high power LED of any color. It hits the LED with a 25ms 250ma pulse once every 2 seconds. This works out to an average current about 3ma. It is powered by any 3v source. I suggest two AA cells but a single 3v lithium coin type cell will also work. With fresh AA cells, the light should flash for about two weeks. The light flash is very intense and is perfect for any attention getting night time application. Source: discovercircuits
