Eternal flasher
Low power circuit for eternal flashing
This circuit was designed by Burkhard Kainka and is intended to generate flash pulses from a single 1.5V cell for years. The voltage for the LED is doubled with a charge pump. My setup has been running for over a year now on a used micro battery.
To reduce the size here are some resistors soldered as SMD1206 on the bottom side.
