Internet-Enabled Electrical Power Outlet

The Idea

We have created a completely self-contained, Wisp-enabled power outlet. Each outlet (top and bottom) is individually controllable through our globally accessible XML API. To show off how responsive (and cool) this project is, we also created an Android App that utilizes our API to turn on and off the outlet with the press of a button...from anywhere!
