[BahaTanju] sent in this oh so simple fish feeder. It’s a mechanical light timer with a simple dispensing bottle mounted to the rotating time wheel. As the timer rotates, food is dispensed and the aquarium light is activated. If you have bigger fish, you could adapt this to work on a solenoid and use a timer with multiple on/off settings.
Or you smack yourself upside the head at Walmart when you see said item on the shelf. I have exactly this design feeding my single koi twice a day except for one difference: the engine is a battery powered wall clock movement.

Nice work Doc Brown.
I’m not really sure I’d want to go that far unless I wasn’t going to be around for a few days. I like feeding them and watching them eat so I think this may take away from that part of the experience in having fish.
Unless you maybe hooked it up to a webcam and remote connection of somekind so you could feed and watch whenever where ever.

It’s nice to see the /actual/ hacks every once in awhile. If the picture isn’t black and white with the Polaroid border, I don’t even read the articles anymore.
Also, cool hack. My friend’s dad did the same type of thing to feed his pigs, he took a metal wheel thing (the tire sits on? Not sure what its called.) and welded about 6 walls inside it, so that it was built like a waterwheel, and he attached it to an older electric motor. After some adjustments, it would load the proper amount of food and dispense it at certain intervals.

Hi all… You may want to check out this video and demo if you want to see another fish tank feeder project. It does the feeding and a whole lot more. Doesn’t require a PC on all the time and you can basically access/control your tank via PC or iPhone over the internet. Its at: http://tinyurl.com/tankvideo Enjoy…

This is just one of those hacks where you smack yourself upside the head and go “WHY DIDNT I THINK OF THAT!?” Brilliant.
