Model Airplane Wing Tip Flasher
designed by David A. Johnson, P.E.

The circuit below is designed to flash two white LEDs mounted at the wing tips of a model airplane.  The flasher unit is powered by a 4.5v supply made of three AA or AAA 1.5v alkaline battery cells.  The average current is about 2ma so a set of batteries should last about 1000 hours of flashing. The circuit uses one hex Schmitt trigger inverter to perform all the timing functions. A single n-channel FET drives the two LEDs, each with a peak current of about 20ma.  The circuit flashes the two LEDs in a pattern typical of commercial airplanes.
