LED technology has changed quite dramatically over the past decade. EE Times has an article in their latest edition that might have some drastic process changes that could lead to some significant price reductions. “Shimei Semiconductor Co. has developed a blue LED grown on a silicon wafer that it plans to make available by next April. Using silicon wafers as a substrate for GaN epitaxy could drastically lower the cost,

Ben Hogan’s “Five Lessons†has a good picture of correct swing arc for a golf swing. Actually that is the reason we named it after the great American golfer, Ben Hogan. I am sure Ben Hogan would
The Concrete Computer Display looks fun, but not exactly practical. I can imagine all sorts of advertising possibilities for this type product. Have a look below for bricks made with the same process. “In co-operation with Christoffer Dupont, student of engineering; Lene Langballe, student of architecture and Dalton Beton (a Danish manufacturer of concrete components), the Innovation Lab project team has developed the first screen of transparent concrete that
