Fish tank and Raspberry Pi

First of all, sorry if lately my posts are published less often than before, but I'm quite busy with several other things and my time for hobbies is quite limited...

Today I will show you a project made for request.

One friend have a small fish tank and he wished to make a really small system, just to check the temperature, pilot lights and few other things .

One Raspberry Pi model A+ was perfect to manage the fish tank with those features, so I decided to start this project and I finished it in few days.

Now this system has been named Aquarius and it's working as it was requested, with some small addition made by myself.

Adding a sensor zone to Sphaera

My Sphaera project is  nice and useful when used alone, but I designed it to be expandable quite easily by adding more Raspberry Pis to the LAN

Also, with the new extremely low cost Raspberry Pi Zero You can add several expansions at an affordable price without sacrifying system performance, as this new board has the same performances of an A+ model.

In this article I will show you just one example of configuration, but adding a new Raspberry Pi would be almost the same for any number of them.

It will be a short and surely not complete description, but could give you a starting point for building something similar. Anyway if you have some question about it, just ask.

Raspberry Pi and astronomy

This time I selected a topic a bit different from usual. After all the blog is about experiments and not only home automation, with RPi...

Since I was a child I've always loved astronomy. I own a small telescope and I took several photos with film cameras, but now I can go a step further thanks to my RPi.
