## Description

Blue Charm Beacons 1.5V LED Flashing Circuit Board, Blinking LED, 10 Months Flashing on Single AA Battery (not Included), Fake Alarm Light

## Features

- 1.5V astable multivibrator LED flasher with blinking red LED (flashes approximately 30 times in 30 seconds). Many different applications limited only by your imagination!
- LED bulb included but not attached to the printed circuit board. It can easily be temporarily pushed into the through holes (friction fit) for testing and/or soldered into place later. Or you could even add some thin wires and place the LED bulb some distance away.
- Battery, battery holder, and wires not included.
- This circuit board will blink the red LED with a single 1.5V AA battery, which should be impossible, but is accomplished using an astable multivibrator circuit.
- The red LED will blink continuously for approximately 10 months on a single fresh alkaline AA battery.
- UPDATE: This new version of this item now has a flashing rate of one flash per second.
