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
