  It is about time that Windows Phone 7 is used for a DIY project. The overall dominance of Android and iOS in DIY projects was stifling.   In a mission to use natural resources more efficiently, Engineer Mike Linnen of Morehead Technologies, has taken several Microsoft (MS) devices and services and turned it into a surprisingly useful DIY automated and controllable sprinkler system. A Netduino Plus controller is at the center of the system, controlling the sprinkler heads. The board ...

DIY Speaker Fabric

Posted by Eavesdropper Mar 1, 2011
Creating a simple speaker on fabric and other materials was demonstrated by Hannah Perner-Wilson in this video. In the best version shown in her experiments, she places wide traces of conductive tape on canvas, and places the material over a rare-earth magnet.   Normal speakers operate by sending a signal through a "voice coil," that is suspended inside a permanent magnet. Force is exerted from the stable magnet to the free moving coil. And the signal through the coil changes it loves ba ...
I saw this robot vacuum and thought, hey why not- I like being messy, this guy's has me covered. Set to buy it, I find that this little bot does not move on its own. I have to push it around? I pass.   However, I like the concept I had when I first saw it. Combine this robot with the robotank, and you have a winner. Everyone's dinner table is a maze of obstacles. A few modifications. Increase the tank's mobility power and battery capacity. Attach the tank as a frame to the vacuum.   ...
  Students and faculty from the University of Michigan's Electrical Engineering and Computer Science Department have developed a small device they call ‘HiJack’ to make sensing peripherals easily accessible to those on a small budget. HiJack is a hardware/software platform for creating cubic-inch sensor peripherals for the mobile phone. HiJack devices harvest power and use bandwidth from the mobile phone's headset interface. The platform enables a new class of small and cheap ph ...
