The holiday season is nearly here. Along with the pleasures (Ooh, fruitcake!) and anxieties (Ugh, fruitcake?) that accompany this time of year, there’s a worry particular to pet owners: Who’ll feed Fido or Tiger while I’m out of town?

There are enough weekends left between now and Thanksgiving to build one of these automated gadgets. They’ll either feed or water your beloved companion while you’re away, or at least auto-snap photos of your pet’s adorable antics. The projects range from easy to anything-but, so you should be able to pick one that either matches your skills, or gives them a pleasant stretch.

Twitter-controlled Pet Feeder

Amanda Ghassaei hacked an off-the-shelf automated feeder to dispense dry pet food in response to a tweeted command. The device utilizes Arduino as the controller, adding an Ethernet shield to receive Twitter data.
