MA, so I'm working on a product design, it's called an Aquaponic system, you put a fish inside a fish tank that has stones in containers on the lid. Then you can add seeds and grow your Herbs year round indoors or start your plants from scratch ready for planting in your Garden in summer, this system has nothing proprietary about it, people have been doing it for years. I was in the pet store yesterday when a girl working there was helping me pick out a submersible pump, when I mentioned what I was doing and my plan to get an Rpi to run the pump and other systems. My goal is an automated feeder as well as cycle the pump and grow lights if needed. Your system might work well for my needs.Not internationally. but they say this country has been joined on "Paris Convention" since a long time ago. I'm not sure that means i'm protected internationally too or not.
Anyway, she was interested in this because she wants a better way to spray a lizard while she's at work, apparently the one she has isn't doing it correctly so, I suggested a device that could sync with a network clock, rather than just run off a counter.
@joeyd999 built a temp sensor I would like to incorporate, but I'm not sure if it's compatible for a system like this.
