Some people go in for a regular ol’ security system, the kind with panels and codes and alarms. And you could do that, sure. Or, you could put together some real home security: a paintball turret.
It took two years to build this bad boy, and the finished product can fire up to 34 balls per second. Per second. Also? It’s portable. You can carry it in a backpack and wreak utter havoc. Or, just admire it on the Internet. That’s probably safer.
Want to build your own? The process is well-documented for paintball-loving DIY enthusiasts everywhere.
