80FFTs Per Second To Detect Whistles (and Switch On Lights)
New submitter Mathieu Stephan writes "Hello everyone! Some people told me that my latest project might interest you. I'm not sure you publish this kind of projects, but here it goes. Basically, it is a small platform that recognizes whistles in order to switch on/off appliances. It will be obviously more useful for lighting applications: just walk in a room, whistle, and everything comes on. The project is open hardware, and all the details are published on my website." The linked video is worth watching for the hidden-camera footage alone: it would be hard to not keep playing with this sensor.
Interesting idea, but I think there would be serious scalability problems. Imagine if this was in each room in your home, and the doors to the rooms were open. Whistling in one room would almost certainly trigger the lights in the adjacent rooms as well.
Typical slashdot combination of the Nirvana fallacy (a solution that isn't 100% perfect is not acceptable), and a totally defeatist attitutude to technical problems.
