Automatic Rear Bicycle Light

(Summer Circuits 2010 article)

Published in issue 403, July/August 2010

This is a design for a rear bicycle light that automatically switches on and off according to ambient lighting conditions. The red LEDs flash with a 50 % duty cycle to save energy; you can modify the circuit to light the LEDs continuously if local laws require it. The circuit can of course also be used as a safety light by pedestrians.
