This automatic fish feeder does not require an Arduino board, but uses a simple quartz time mechanism instead. Every two hours a portion of fish food can drop out of a container when it passes the hole in the bottom plate. You don't have to fill them all and you can bring variation in the food by filling the containers with different stuff. For outside use, a lid keeps rain and birds away. If the portion size does not match your feeding schedule, just scale the z-axis up or down. There is also a version for continuous feeding, of cause you don't have to fill all the containers. The bottom plate should be printed with support to keep the center opening for the clock nut open. It might be necessary to add a minimal amount of glue to the shaft for the large clock arrow. Choose a color that matches the surroundings. As an option a dial can be added to the lid, indicating the feed times.
Hey Donald, go away, this is for fish only!
