Backyard Aquaponics
A place to discuss aquaponics

Les, don't have details as to the inner wrokings, but would seem simple enough for a man of your expertise to figure out and perhaps refine....

Then I also found this DIY "on demand feeder"... which I guess is a similar adaptation....

Tks Rope, trouble with demand feeders is ya gotta train the fish...and...they could empty the thing just having fun




...also...I've got a bloody auto fish feeder



Only want the feeder when off on hols, so it won't be a permanent fixture, thanks for the thought tho

Plans were put up here once before for how to make an on demand feeder. Not too difficult - but I tend to agree with Les. The mechanical one he has seems like a good option.

Yeah.... I know...

Yeah....and I know you know


you know!

I didn't know you knew he knew, You know?
Les how is that auto feeder working for ya?

Parnk. It runs on a 6V DC battery (can be linked to a small solar panel as well) and has a very accurate digital timer don my butting in to this thread but I thought I'd mention a fish-feeder option I have started using. I found an automatic game feeder on a US web site for Hunters etc. It's not expensive (about US$40 I think). It has a very accurate digital timer built into it capable of 16 feeds a day with times down to 1 sec and up to 30. The motor spns a small disc uder a hopper (your provide the hopper. I iuse a 20 litre drum that holds about 20kg of feed) and the feed drops down through a small funnel onto the spinner plate. When not in use the feed forms a pyramid on the plate and sits there waiting for the next feed time. It allows me to be away from the tanks for days at a time if need be. The site is Cabelas - you'll find it on google.

have fun.

John, it works fine.....tested it for 2 days, feeding morning and evening....nice to watch with stubbie in hand. - need to set up a platform over the main tank for it and move the SP into there as well

Looking at going on hols about mid august so will give it a longer test before leaving

Thanks for the info pmrid, have a Cabelas near by. Never even thought of them silly me they are a hunting and fishing sportsman store neat stuffs.
Sounds good Ell as you know I'm still shopping for a good one.

I had a friend last week showing me one of those deer feeder sites last week, the timers looked well suited for fish feeders..

This one?

the "Feeder Kit" on the cabelas site looks like it can be made into something.

Les mite have a fish feeder but has he found the instruction manuel yet
