Birdwatching Meets a Computer-Controlled Water Cannon, Awesomeness Ensues

squirrel turret

Sure, squirrels may bother the average home owner, but few have attempted as creative a way to control them as this automated water turret. Check out the video after the break to see how this was accomplished, but if you’d rather just see how the squirrels reacted to getting squirted, fast forward to around 16:00. According to [Kurt] he was sure this would be his solution, however, his conclusion was that “squirrels don’t care.”

As for the presentation, it’s more about how to use [OpenCV], or Open Source Computer Vision. It’s quite a powerful piece of software, especially considering that something like this would cost thousands of dollars in a normal market.  An Arduino is used to interface the computer’s outputs to the real world and control a squirt gun. If you’d rather not program something like this yourself, you could always simply use a garden hose as someone suggests just after the video.

Easy camera tracking with a quadrocopter

[DJ Sures] has been pulling all-nighters lately to get his AR Drone Parrot build off the ground. Now that it’s up and flying around, he managed to get it to follow objects around the room using on board cameras.

For the build, [DJ Sures] used the AR Drone ‘flying video game’ quadrocopter. This toy has two on board cameras that can viewed over wifi. All that’s needed is some interesting software to make things fun. The camera tracking of EZ-Builder software was brought into the mix so the AR Drone can be controlled via object or speech recognition, wiimotes, tablets, or terminals.

[DJ Sures] has come up with some slightly terrifying awesome builds like a Bluetooth Teddy Ruxpin, realistic Wall-E, and an awesome Omnibot 2000 refurb. This is his first flying hack, and the first to fully exploit the camera tracking of the EZ-Builder software. Check out [Sures]‘ copter following him around a room after the break.
