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.

By experimenting with the photovoltaic reaction in solar cells, researchers at MIT have made a breakthrough in energy efficiency that significantly pushes the boundaries of current commercial cells on the market.
We looked at a number of sources to determine this year's greenest cars, from KBB to automotive trade magazines to environmental organizations. These 14 cars emerged as being great at either stretching fuel or reducing carbon footprint.

A quick look into the merger of two powerhouse 3D printing OEMs and the new leader in rapid prototyping solutions, Stratasys. The industrial revolution is now led by 3D printing and engineers are given the opportunity to fully maximize their design capabilities, reduce their time-to-market and functionally test prototypes cheaper, faster and easier. Bruce Bradshaw, Director of Marketing in North America, will explore the large product offering and variety of materials that will help CAD designers articulate their product design with actual, physical prototypes. This broadcast will dive deep into technical information including application specific stories from real world customers and their experiences with 3D printing. 3D Printing is
