So i’d imagine this only works for pellet food. I wonder if he has had problems with it jamming

I suppose another way you could construct the dispenser would be to have a rotating disk assembly

It doesn’t have enough colored wires! :)

When is a display ever overkill! The more displays and usless graphics, the better!

the one I bought at the pet store is just a disk with a tube running through it stuck on a lamp timer type contraption, the tube is slit so as it turns it scoops up some food and when it rolls around it dumps

Where can I get some automatic fish? Because those sound like the ones you don’t need to feed.

@Edward5,

Look at Google images, look at shopping, there are a lot of designs. The one I bought a while ago consisted of a plastic housing containing a clock mechanism with a drum affixed to the hour hand. Inside the drum was a tube with a hole in the side acting as an intake, and the opposite end was open to dump into the tank. As it rotated twice daily, the intake hole scooped up some food, and the outlet dumped it into the tank about 6 hours later.

It was kind of tricky to set the appropriate amount of food and still have confidence that you weren’t going to starve the critters.

We solved all those problems when we gave the aquarium away to a nephew. :-)

You might want to consider building an automatic fish catcher:

No the food does not get stuch because of the shape of the sliding hole. It has triangle shape orifice and when its getting closed it pushes the food aside. Ill try to upload the video with food despencing…:)

@Ryan Finch
what you are saying is good but it has limitation.
I wanted adjustable amount and also it has one added feture.
when feeding is done then it triggers a relay which stops the air pump in aqurium for 30 mins so that wishis can have there meal in peace.

Di you notise that the clock stops while feeding … starting feeding at 11:11:00, was feeding for about 25 seconds and then starts the time at 11:11:01

@ Birgir Thor
Nice observation. I think you are right. I used Timer T0,T1 and made RTC of it. i think i missed to update the display registers while feeding. Thanks for the comment.

@ Hammerhead
mailed you the code for this. there is comment in the code please edit it. also there is one bug which i noticed from above comments. while feeding the RTC stops . need to fix that also…
