For Ryan Shannon and friends' complete instructions on how to build your own electronic version of Twister and associated microcontroller code, click here.
Engineering student Ryan Shannon and friends created a high-tech, interactive version of Twister that tracks the positions of players on any of 24 possible locations. A dc motor spins the player position arrow, the location of which is tracked by two photo interrupters. A micro-controller correlates the signals with game position, sending a series of pulses to a sound chip that issues vocal instructions, also displayed on an LCD. To deter the potential for cheating, copper switches on the board track the position of all players.

Almost every automaker has had to 'pick a side' when it comes to alternative fuel options and ways to divest from a reliance on gasoline. Fiat is looking to back compressed natural gas or liquid propane as an interim solution.
Plastic may not be the most beloved of materials to the more environmentally minded, but Plasti 2012 aimed to mold a different opinion of the material in people's minds.
The rare earth element market has become steadily more rational, and new sources coming online will continue to reduce costs. Still, it is unlikely that prices will drop to their former lows.
Against a backdrop of mounting product complexity and a need to keep a lid on development costs, companies are recognizing a need to make simulation a more integral part of the design process. In response, vendors in the CAD world are building out CAE functionality as part of their CAD suites while simulation vendors are building tighter integrations to leading CAD tools. Keith Meintjes, Ph.D., Practice Manager, Simulation and Analysis at CIMdata, Inc., joins Design News CAD Editor Beth Stackpole in this radio program to explore the new face of integrated CAD and CAE, how companies are benefitting from this tighter partnership between platforms, and how integrating CAE earlier in the development cycle pays off in optimized product designs.
