It's very interesting to know a geek create a cat-feeding device using Linux. Chris McAvoy tells you the complete guidance.
Give your Linux box the power to control real-world events with an inexpensive microcontroller from Parallax, a Python program and some serial port magic.
Cats love toys. Our cats, Cotton and Tulip, slowly have taken over our house with their little plastic doo-dads-ping-pong balls, furry mice, bells, springs and things to scratch. The cats are rarely bored. On the weekends, my wife and I oblige the kittens by tossing their toys around the house, flinging strings and jingling bells. We scratch their backs and feed them treats. They're both in love with these little stinky fish treats; all we need to do is shake the can, and they stop whatever they're doing and dash to the kitchen. Their English lexicon now includes their names and the words good and treats.
Monday through Friday, nine to five, however, the cats are responsible for their own entertainment. While we're away, we're sure the cats have a good time with their toys. Our rugs almost always are moved around, ping-pong balls end up in water dishes and fur covers our chairs. The only real difference between the weekday and the weekend is our presence and the lack of treats.
We have to work, but that doesn't mean our cats should have to go without stinky little fish, right? Why should our economic necessities have a negative effect on their treat times? Isn't it our responsibility to build them an Internet-enabled, Linux-based, cat-feeding device?
What a geek :-D
