Dave Hunt ‘s been at it again. Here’s his latest: a home-made smartphone based around a Raspberry Pi.

Of course, the limitations of this project were clear: I could only keep tabs on the tank while on my home network. What if I want my fish to text me when it needs my assistance?  The problem, until now, was that getting the Raspberry Pi to initiate communication was hard. I experimented with a  Node.js receiving application, and contemplated buying a server from which to run it (since my Bluehost server space doesn’t support a Node installation). The other way to get the Raspberry Pi to talk to me was to teach it to text my phone. There are also  many ways to achieve SMS support ...
