Model Airplane Wing Tip Flasher
, Circuit 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. |
