Keeping the dog out of the garbage can or your cat from going through your underwear generally calls for a lock and key scenario.  But that’s hardly a geeky answer and won’t condition Rex to think twice before he digs through bacon grease and chicken bones.

Enter the SpyNet Laser Trip Wire.  Yup, the same tech we grew up watching in movies – Catherine Zeta Jones comes to mind – is now ready for your kitchen, living room, heck even your cubicle.

The system includes a transmitter that beams a laser to a receiver unit, as well as 2 mirror units to expand its reach around corners and through door ways.  If someone, or something crosses its path an audible alert will be sounded, notifying you that there is an intruder in your midst.  You’ll need 6 AAA batteries to power this setup, but they should last up to 5-10 hours with continuous use, at least that’s our best guess based on our laser experience.

ThinkGeek sells it for $34.99.

Grew up back East, got sick of the cold and headed West. Since I was small I have been pushing buttons - both electronic and human. With an insatiable need for tech I thought "why not start a blog focusing on technology, and use my dislikes and likes to post on gadgets."
