Turn Over Alarm Kit

Here's a kit to stop your brother or sister from picking up your things! If they pick up this kit and turn it over it will produce a loud tone which won't stop even when they put it back down (you need to disconnect the battery to shut it off). Can be propped up next to a door so that when the door opens the alarm falls over and sounds.

Fun to build and use! Features gravity switch, SCR and IC circuitry driving a small speaker. Operates on a 9V battery (not included). Size of board: 2 1/2” x 2 3/4”.

Complete with all parts, PC board and instructions. Skill Level 1.
