Make Your Own Internet-Controlled Lamp with a Raspberry Pi

The Raspberry Pi is great for powering all kinds of home automation projects. If you want to get those power outlets connected the internet so you can control them from anywhere, DIYer Jack Minardi shows off how to do just that.

The system here uses some cheap remote controlled outlets, some transistors, breadboards, and the Raspberry Pi to power a system where you can remotely turn off a lamp from anywhere. It's not just a lamp either, you can turn anything connected to the outlet on and off from the internet. The build requires some soldering, but if you're interested in building something like a DIY WeMo for yourself, Minardi's build is a good place to start.

It’s a very simple board complete with a small relay, a diode, and 2 resistors. The 8 pin header provides connection to two hall effect sensors that detect the status of the garage door, and the original door opener. He then connects this to an open-source wireless Arduino clone of his own design, dubbed the Moteino. A pair of these communicate to the Raspberry Pi which acts as his secure home automation gateway server.
