An accurate demand feeder for fish, suitable for microcomputer control.
This paper describes an easily constructed and inexpensive demand feeder. The feeder is driven by an AC synchronous motor and gearbox and is suitable for microcomputer control. It will operate with inexpensive commercially available pelleted fish food, and will consistently deliver a single pellet for each operation of the motor. The components and materials can be purchased for approximately 23 pounds.
