Description

This is my Android-powered, automated cat feeder. A Python script runs via SL4A on the phone serving up a webcam feed and taking care of triggering the feeder on schedule.

For more details, video, and code, see my blog entry here: http://www.damonkohler.com/2010/11/android-automated-cat-feeder.html

I'll probably be adapting this to use an RTC chip soon. I'll post updates if I do.
WOW. I need to try for my dogs. My 'Ardi-Fu' isn't as strong as yours, any examples of simple timer circuits or level triggers? Great work.
TOTALLY AWESOME!!!

Again one thing from my todo-list :) This is what I love, and hate about Thingiverse. It's awesome to see this stuff. The downside is that I was on record with the press that I would design and print a cat feeder tool, now you beat me to it! Awesome work, though!!! I'll definitely think of printin
g one and reusing my old Android phone. I think I'll have to also print the dispenser... and make a derivative. Also thanks pointing out the code. Makes for an awesome SL4A implementation!

Instructions

To print this on a MakerBot, you'll need to be careful how you orient the STLs on the platform. They're a tight fit! You'll need to print two of the back brackets and one of the front. The motor is bolted on to the front bracket from the inside. So, you'll need to attach the drive shaft and motor to the bracket first and then use the brackets to mount the cereal dispenser.

When printing the drive shaft, I recommend using a raft. In addition, I got the best results when using comb and multiply to print a 2x2 matrix. This allows the layers to cool sufficiently, making a tall and skinny print possible.

If you intend to use the food chute, pay attention to the height you mount the cereal dispenser. The food chute is approximately 10cm high.

Little do you know, your cat knows how to hack too! ;)

Great invention!
Awesome!! I have something very very similar, but not controlled by a mobile phone or webcam, tho it is cobbled together with parts.. Did it long before the MakerBot was a twinkle in my eye. Eventually gonna interface it with other things but haven't done that yet.

Excellent work on yours! =-X
