A PyCon 2012 talk by Kurt Grandis on building an automated water-squirting turret that uses Python and computer vision to detect and drive off squirrels from a bird feeder.

HN loves it as a funny, inspiring hobby project and calls it one of the best conference talks ever.

Indeed. Here's something somewhat related, from PyCon 2012. It deals with using computer vision to fire a squirt gun at squirrels. The principle is basically the same. [VIDEO]

In related squirrel news: The "Daylight Robbery" documentary has some very interesting squirrel obstacle courses. You can find it on youtube - [LINK] "Militarizing your Backyard with Python" shows how to build a water-hose-turret that automatically recognizes and blasts squirrels - [VIDEO]

"Militarizing Your Backyard With Python" - Perhaps the best presentation to a programming language conference in history. [VIDEO]

I don't think you'll find a 'quick hack' but what you're asking is definitely possible as a project. Check this video out for ideas(guy used ML/servo controlled squirt gun to get rid of squirrels from his bird house) [VIDEO]

Ten years ago, somebody built a squirrel detector/watergun combo to protect their bird feeders without harming the squirrels, [0] [0] [VIDEO]

Some Hobbyists still want to push the envelope. Think the artist equivalent of the guy building a AI controlled sentry gun for shooting squirrels with water. [VIDEO]
