DIY Automatic Fish Feeder.

Automatic Fish Feeder in Action. |
Finally I am done with my Automatic Fish Feeder. Its simple
and cost less than Rs 300.
Basic Principle:
A cylindrical drum is attached to the hour needle of an
electronic alarm clock. The Drum completes 2 rotations in 24 hours. A small hole in the drum with a straw, ensures that food is dispensed every 12 hours. The cut made in the
straw, determines how much food is dispensed each time.
Here are the things you need:
- An Electronic Analog Alarm Clock like Orpat
Alarm clock.
- A small plastic cylindrical light weight
container (preferably transparent). I took a small container in which you get
camphor balls used in religious rituals (Pooja).
- A small plastic straw/pipe. A pipe used in Aquaguard
water purifier is fine. Its diameter is around 7-8 mm.
The operation is self explanatory. If you are still confused
then you can refer the following sites.
A few tips:
- Make the hole for the straw on the drum, a bit smaller so that you do not have to use a glue to hold it in place. You can then create 2-3 small straw with different cut size to dispense different amount of food. Whenever you have less fishes in tank you can use the straw having a smaller cut.
- Do not load the drum full. Keep it half filled otherwise all the pellets may drop out in one go.
- Try to get the lightest cylindrical drum so that you can fill more food pellets.
- Every clock needle motor has a threshold of how much load it can take. So do not over load the clock with a heavy drum filled with food pellets.
- You can use mustard seed for testing your DIY Automatic Fish Feeder.
