fish feeder

The store of dried feed is held in a trough with V-shaped sides (figure 1). At the bottom of the trough is a cylindrical container which runs the length of the trough, and which has one side cut away. This cylinder is driven, via a reduction gear, from a small model motor. As the container rotates it will fill when the open side is uppermost, and empty into the aquarium as it rotates. The number of revolutions made at each feeding session, and hence the amount of food delivered, is controlled by the electronic circuitry. A cowl at the bottom of the dispenser prevents splashing caused by the fish or the aerator from making the feed sticky and thus clogging the dispenser.
