This easy to make and inexpensive homemade (diy) automatic fish food feeder was designed to automatically feed my pond fish but it would work just as well in an indoor aquarium. The feeder combines a low rpm microwave carousel motor and an old auger type wood working drill bit to slowly feed the food to the fish. A timer, set to stay on for a predetermined time, controls the feeder. Click here to see more details:
