I have designed a laser pointer security box that powers off of a 9v
battery or an A/C adapter. This box can be built easily, and for about
$10 from Radio Shack parts! How it works: You place the box on one side
of the room and a laser pointer on the opposite side of the room, and
when someone or something crosses it, then it activates an onboard
buzzer!
Plans are only $2, and they are sent via email as soon as the money is
received!
If interested, please email Creator102@juno.com.
You will then be given ordering directions.
