Reinventing the Clapper With a Knock-Based Home Automation Controller
An anonymous reader writes with a snippet from Hack a Day: "Clap On! Clap Off! was super awesome when The Clapper came out in the mid-eighties. Now [Mathieu Stephan] is trying to make the concept much more functional. He put together a controller that lets you knock on walls to control things around the house. It's called the Toktoktok project and uses small boxes to receive user input and control items like lamps and computers." As the project website points out, Stephan is keeping the project intentionally open.
It's not necessarily, or only about laziness, but aesthetics too. Also handy if you have a room with 3 entrances, but only one has a light switch, etc.
To be fair this is not targeted just at turning on and off lights. The article states that is can control any electronic device: computers, music players, cooking... anything. And the creator explicitly says it is unencumbered with patents so it is an idea any one can use to improve any existing technology.
Sounds like a win-win
