Forrest M. Mims III: Fridge Alarm Kit

Without Engineer's Mini Notebook: Volume 3

Have a food burglar in your midst, or just trying to keep the midnight snackers at bay? You need a fridge alarm. This handy little gadget sits quietly in the fridge until someone opens the door. When the door opens, it turns on the light inside the fridge. The light triggers the photocell on the alarm causing it to emit a shrill tone. It may not stop the perpetrator, but it will make them think twice about opening the fridge door again. Visit the Jameco Workshop page for complete build instructions.
