Here’s the link to the article that I’m talking about: The Fish-O-Matic
This is a smaller, indoor version of something that I’ve considered doing. I’ve been interested in hydroponics since reading older Heinlein, Asimov, and Norton sci-fi, and how it could combine air and water recycling, along with providing food. A couple of years ago, I came across some articles or videos talking about using a tub of tilapia, and pumping the water up into a gravel-filled trough that the plants were all planted in. It kind of re-ignited my fascination with the whole process, especially looking at how I could control it remotely, complete with wide-ranging data reports by using microcontrollers and basic sensors.
This is basically the same thing, just built on a smaller scale, using indoor-style parts. I love the way the system keeps up with “inventory” so to speak, and orders more as needed. That’s something that I’ve never thought of doing before. It has a lot of information about the actual nuts and bolts of creating a system like this, and some of the hurdles that will have to be overcome.
So this is something that I’m really interested in. I’m still thinking about building one of these (scaled way up) one day, but I’m just not in an appropriate place for it right now.
