Homemade Speakers
I had the awesome opportunity of taking the EE423 Speaker Design class offered at USC while I was going to school there. The class is taught by engineers from JBL, with some help from people like Tom Holman (the TH in THX guy!), who happens to be a researcher at USC. I learned a lot about speaker design, and ended up with a pretty awesome pair of bookshelf monitor speakers. The speakers use Vifa TC14SG49-04 5.5″ midwoofers and Peerless 53 NDT Neodymium 1″ tweeters. The inital boxes were prototyped in cardboard. Despite looking absolutely terrible, using 3 layers of sandwiched cardboard actually works extremely well in terms of audio response. Here you can see a diagram showing the 200-10 khz response (tweeter is thin line, midwoofer is thicker…

Dean Kamen Thinks His New Stirling Engine Could Power The World
For the new issue of Forbes Magazine I wrote an article about David Crane, the visionary CEO of NRG Energy. When I met Crane for lunch a couple weeks ago, no sooner had we sat down than he began singing the praises of this new contraption he had in his basement. The machine — which can generate 10 kilowatts of continuous power, fed by Crane’s natural gas line, is a new iteration of an old creation, the Stirling engine. This version, called the Beacon 10, was created after a decade of engineering by famed inventor Dean Kamen. I caught up with Kamen (who is best known for creating the Segway scooter) over the phone last week to ask him about the device. We’ve turned his …

Microsoft Brings Penny Arcade Artist To An Engineering Team To Work Out Surface Pro 3 Issues
Microsoft is gearing up to begin shipping its Surface Pro 3 tablet, and many have already had a chance to test out the latest in tablet/laptop hybrids. One early tester is Penny Arcade’s Mike Krahulik (aka Gabe) who was a huge fan of the Surface Pro 2, because with the stylus, it was an awesome digital artist tool for hand-drawn creations. Gabe wasn’t so impressed with the Surface Pro 3. He said it introduced some lag into the equation for menu navigation and drawing (I’ve tried it myself and I found the same thing), and which put the home button in a new, much more inconvenient location. Microsoft took this feedback to heart, so much so that they brought Gabe in to provide feedback …
