Modern security systems are great for protecting your house, but what if you have a specific valuable that you want to keep safe? Perhaps you want to setup a cool laser security system like you see in the movies. If that’s the case, you can build such a contraption rather easily following this Instructables guide.
The system uses a laser tripwire to detect whether or not someone has crossed a certain point. Once someone passes through it, a webcam will take a picture of the intruder and post it on Twitter. Now this may not get the police there in time to stop them from running off with the goods, but at least you’ll know who did it.
