The Raspberry Pi at $25 - $35 is cheap enough to be used in every light switch and wall socket of a house as a distributed home automation system. In this episode, we look at using Node.js as the basis for such a system and the hardware necessary to make it happen.

This represents the very beginnings of a larger project but I thought I'd make it available in case others are interested in developing the idea.

The software used in this project is available for free from GitHub at:

Here's a PDF datasheet on the solid state relays I'm using: http://sharp-world.com/products/devic...
