Autonomous sentry guns are fucking awesome, as long as you're not on the receiving end. Think of all the fun you had in Half Life with the sentry guns... imagine having the very same fun in your own home or neighborhood. Wouldn't that be a hoot?

This video is just a short little dicktease and doesn't tell you anything. What you want are the entire DIY build instructions (software, source code, build manual, hardware) for how to build one in your garage. That my friend, you would find here.
