How to Make Your Own Laser Tripwire



Who's been stealing my Twinkies from my cubicle here at Neatorama HQ? This time, I'm going to catch Miss Cellania in the act! Instructables user action_owl designed and built a homemade laser tripwire alarm system that tweets a picture of anyone who crosses it:

This instructable will show you how to construct a laser tripwire that can twitter and grab an image from a webcam, as well as execute any command you can put in a bash script.

This instructable is actually quite simple and is even suitable as a beginner arduino project. It requires a GNU/linux (or possibly Mac) operating system with the arduino IDE and Processing IDE working properly.

Talk about going the long way.

There's free software that turns ANY webcam into a motion tripped spycam.

No wires, no lasers, no sharks. Just the webcam, a computer, the software, and optional thieves.
