A swede goes nuts and builds a cat door with built in face recognition, heating, lights, rfid etc based on raspberry pi:

OMG, I was just wondering about if RFID works to scan cat's ID microchips!

Now you just need to automatically post the pictures to imgur/reddit and let the karma flow in. :|

For bonus points, feed the score of each imgur/reddit post back into the Kittydar neural net that is doing cat facial detection so that it learns to snap photos that yield maximum karma.

"or put his butt on the camera, it fails to tell me my cat was eating."

My favorite issue this year.

I know a couple shelters that would love cat/dog facial recognition that was able to identify the animal based on it's face.

This project isn't that, but it's still pretty cool.

I'm reminded of this DIY cat door that used pattern recognition to prevent the owner's cats from bringing dead animals into the house.

For some reason, I'm on all the different things posted here, this makes me want to get into robotics. I've been thinking about ordering a raspberrypi, or a MicroPython board, etc., but something holds me back. Maybe the fear of getting into something that I won't have time for.

I love cat based electronic projects. I've been trying for the last few weeks to come up with a real time GPS tracker, but I just can't seem to finalize the parts list. All gps chips I know of are too big and tend to overheat.

Then this might be worth checking out, video: https://www.youtube.com/watch?v=DMNSvHswljM

Not sure how you could _not_ find small gps units nowadays. Have a look here, for example: https://www.sparkfun.com/categories/17

I wonder if this will be quick enough to trigger a cat scarer: water spray, high frequency tones or flashy lights
