Automatic Small Fish Feeder - Parts

thingiverse

I enjoyed using Cobeldas Automatic Fish Feeder, but it released too much food per cycle for my liking. To rectify this issue, I decided to modify the feeder by designing and crafting a smaller hopper and an auger with increased turns to disperse the food in smaller amounts. The component assortment is a bit chaotic, but I thought sharing all the sources would be beneficial for anyone traveling over the holiday season who might not intend to take their fish along. Our experience: We used an Arduino board paired with a continuous rotation servo motor. It was powered by a MacBook equipped with Skype set to auto-answer and had a remote desktop application running, allowing me to adjust it remotely whenever necessary if adjustments seemed warranted from afar. I must admit that watching it operate from a thousand miles away proved quite amusing.
