Goldie Fishwater & the Internet-Connected Aquarium

The control interface for the tank (left). The water is at room temperature. Motor A is the camera platform. Motor B is the fish feeder. The Relay button controls the pumps and bubbler. The camera was raised to water surface level (right), and I had just used the feeder. Goldie was right there ready for the pellets.(Source: Cabe Atwell)

Re: Other approaches

Another approach, though I am sure PETA and fish lovers would call me evil, buy another fish if this one happens to die while I am on vacation. For the cost of the various hardware and time, a lot of replacement goldfish could be bought.

Maybe not pet fish, but... Take a look at this...



You want to keep a close eye on these pets. They are armed.

Other approaches
William K.   12/11/2013 10:25:47 AM
Given the relative complexity of the system, it seems that there could be some alternative approaches that would be simpler and more reliable, and probably take up less space. For monitoring the temperature, a thermometer stuck to the far side of the tank could allow temperature checking as part of the video monitoring procedure. And with the price of cameras being quite low, multiple cameras would eliminate the need to have a moving platform and all of that control and drive hardware. The automatic feeder would still be a challenge and I can't offer much of a suggestion without understanding a lot more about how it is supposed to function.

Of course I realize that the whole project is designed to be an interesting writeup and so it had to include the various systems. But sometimes there is a simpler and more reliable way to do things, often without needing to include an Arduino.

I think Cabe and Goldie are safe.  The patent has a very narrow scope, always referring to a spa.

Looks like you have infringed patent US6782309. (seriously). Prepare to be sued by your friendly local patent troll.

Well that is certainly a clever way to ensure your fish is well looked after, even when you're not around. I doubt there is another pet fish in the world under such tight surveillance.

Toyota aquarium

I wonder if the people who built the Toyota Highlander aquarium (which we wrote about recently) need an automatic fish feeder. Seems like a natural for a bunch of fish sitting around a tank at a trade show.,

While every company might have their own solution for PLM, Aras Innovator 10 intends to make PLM easier for all company sizes through its customization. The program is also not resource intensive, which allows it to be appropriated for any use. Some have even linked it to the Raspberry Pi.
solidThinking updated its Inspire program with a multitude of features to expedite the conception and prototype process. The latest version lets users blend design with engineering and manufacturing constraints to produce the cheapest, most efficient design before production.
XYZ, Rabbit, and Disney innovate on the 3d printer in different ways -- from price point to using materials such as yarn.
MIT students modified a 3D printer to enable it to print more than one object and print on top of existing printed objects. All of this was made possible by modifying a Solidoodle with a height measuring laser.
Siemens released Intosite, a cloud-based, location-aware SaaS app that lets users navigate a virtual production facility in much of the same fashion as traversing through Google Earth. Users can access PLM, IT, and other pertinent information for specific points on a factory floor or at an outdoor location.
