This is the story of how I built an all-seeing eye with Ruby, and how I use it to defend the sanctity of my suburban home. Using a Raspberry Pi and some homemade motion detection software I've developed a home security system that can send me notifications on my phone and photograph intruders. It uses perceptual hashes to detect image changes and archives anything unusual. I can even set a custom alerting threshold and graph disturbances over time. If you've ever had the desire to be an evil wizard with a glowing fireball of an eye this talk is perfect for you. Come play with Sauron.
