Automatic Small Fish Feeder - Parts

thingiverse

I liked coberdas Automatic Fish Feeder but it dispensed too much food per cycle. I wanted to use the feeder to feed 5 neon's for a 2 weeks so I created a smaller hopper and an auger with more turns to dispense the food in smaller amounts. The parts collection is a bit of a mess but I thought I'd throw all the source out there for anyone traveling this holiday season that aren't planning on taking their fish with them. How we used it: We used an Arduino with a continuous rotation servo attached. We powered it with a Macbook that had Skype on auto answer and had a remote desktop app running so the kids and I could adjust it remotely if we thought it needed it. I've have to say it was kind of fun to view it from a thousand miles away…
