It's 4am, and I'm sound asleep dreaming of robots when I'm startled awake by 10 lbs of hungry cat jumping on my face with a pleading "mew". I get up, feed the cats, and unsuccessfully attempt to resume my slumber. This scene repeated itself every day for only a couple weeks before I decided I needed an automatic cat feeder to maintain my sanity.
The feeder needed to only handle dry food, be able to ration food quantity so that the cats wouldn't get fat, and it needed to have a lot of storage so that the cats wouldn't starve while my wife and I were traveling. Similar off-the-shelf feeders cost upwards of $50, and I like a challenge, so I set out to build one myself.
Build details and more pictures after the break.
