stoolpigeon writes "Hitting middle age has been an interesting time. I catch myself thinking about how well kids have it today and sounding a lot like my father. One difference is while my dad was happy to teach me about sports or cars, we never spent any time knocking out code together. I think he did realize that home computers were important and I will always be grateful for the Commodore Vic-20 he brought home one day. It was a substantial purchase for our household. I spent many days copying lines of basic from magazines and saving the results to cassette tapes. In my home today we have a considerably better situation, computing wise. There are usually a couple laptops running as well as the desktop machine upstairs. My kids take for granted what I found to be amazing and new. Still, that's all pretty normal and I'd like to give them an opportunity to go deeper if they are so inclined, just like we give them opportunities to explore other skills and pursuits. With that in mind I brought a copy of Hello World! home a few weeks ago, and the response from my oldest has been surprisingly enthusiastic." Keep reading for the rest of JR's review.

eldavojohn writes "Dr. David McKinnon from Queensland University of Technology, has recently launched a site that turns your sets of 2D images into 3D bump maps by way of 8 years of his research. The catch is that you need to have between five and fifteen photos of your object and they must overlap at least 80 to 90 percent. So with a video of an object, one might be able to extract every nth frame and use this site to generate a 3D model. Doctor McKinnon said, 'The full version of this software would be great for realistic learning simulators and training software, where you want everything to look like the real thing. This technology could also be great for museums wishing to turn their display objects into 3D images that can be viewed online. We are even looking into making 3D models of cows to save farmers spending thousands of dollars transporting their cattle vast distances to auction sites, allowing for an eBay style auction website for cattle. Films, animations and computer games could also benefit, since 3D film making is taking over from the traditional 2D method of filmmaking. Another application is allowing people to create 3D models of their own face to use on their avatar in computer games or 3D social networking sites such as Second Life or Sony's Home.' Physorg has more details."

tugfoigel writes "Built by "Kevin" for a contest, this computer-controlled alarm clock is touted as the world's largest. To be more specific, he 'mounted a large air cylinder to the head of [his] bed and a valve, controlled by a computer, which [he programmed] to wake [him] up in the morning.'"

Francesco Fondi writes "An Italian Company is using RC scale model submarines to lay fiber through Milan's sewage system. The RC submarine used is the Neptune SB-1, produced by Taiwanese company Thunder Tiger. It costs ca $600 in US hobby shops." In Italian, but the pictures speak for themselves.

Two six-year-old boys built a toy nuclear power plant complete with a radiation warning sign, and managed to freak out an entire German town. The boys left their creation on the street after they had to go home for dinner. A passer-by notified authorities, who cordoned off several streets, raised a public alert, and rushed a radiation detector to the scene to figure out how hot the empty computer case with a sign taped to it was. "It wasn't a prank, they were just playing," a local police spokeswoman said Tuesday. "The boys tried to go back later to carry on but the fire brigade wouldn't let them through."

Mel Gibson's Sit 'N Spin. Dizziness is next to Godliness.

The first projector I remember seeing in person had three great big glass eyes (for red, green, and blue lamps) and BNC connectors. It probably weighed more than 100 pounds, and had to be carefully calibrated to align the lenses. Now, I've got a projector above my head that weighs less than a Neal Stephenson novel and has a sharper, brighter image than that monster. I've been looking into LED projectors for a few years now; in that time, I've been waiting for them to come down in price and bump up in lumens. So I was very curious about BenQ's GP1 LED projector (also known, somewhat oddly, as "Joybee"), and was happy to get a sample for review. It may seem retrograde to bother with an 800x600, 100 lumen (no missing zero there: one-hundred lumen) projector in 2009 A.D., but for the past four weeks, I've used it as my primary display, and come out happy. It has some drawbacks, but it's an impressive little device for its $499 pricetag, and I hope a harbinger of even better things to come. Read on for my take on what BenQ got right, and what rough spots stick out.

Kohenkatz writes "As noted in PreCentral.net's forums, the 'webOS Reset Doctor' has been leaked. It includes the webOS root image. From the article: 'Code-inclined individuals on the PreCentral forums have already cracked open the ROM and are getting an unfettered glimpse at the Palm's new platform, which, for the layman, means it should open the doors for some crazy Pre hacking and possibly hint, by way of unfinished / unused code, at what's to come for the platform — and, if we're really lucky, maybe someone will be able to look at this and move us one step closer to an unlocked Pre that could jump onto Verizon's network. Amusingly, you also get to see all the comments left by the devs in the code, guaranteeing a few good chuckles from others who can relate.'" People have already uncovered icons for MSN and AOL, as well as references to the Palm Eos, a rumored successor to the Centro line.

robotsrule sends in a follow-up to our earlier discussion of the bankruptcy of Ugobe, maker of the Pleo robotic dinosaur: "Jetta Company Limited, based in China and Hong Kong, the company that manufactured the Pleo baby robot dinosaur for Ugobe, has bought the intellectual property rights and other assets at the Ugobe bankruptcy sale that occurred on May 21. Jetta is an established company with a 32-year history in manufacturing. They have issued a short press release announcing Pleo's rebirth. Steve Ohler, the US liaison for Jetta, confirmed the news, saying that the company is firmly committed to re-launching Pleo and continuing the line including producing accessories such as the vital battery and charger components. Jetta, as the original manufacturer, is the best possible company to have acquired Ugobe's intellectual property and to announce plans to re-launch Pleo. Ohler remarked that all of the equipment needed to produce Pleos and accessories is still intact and ready to go."

It admirably performed its task of providing speedy Wi-Fi Internet to other devices via an EvDO Rev. A connection. Ironically, the device even improved the experience of using the iPhone, making it usable for surfing where its native network (AT&T) doesn't even connect."

Mike writes "Swiss auto company Green GT recently released the first details on a svelte all-electric supercar that is being heralded as the most powerful electric race car ever built. Designed with the 2011 Le Mans race in mind, the Twenty-4 will boast a sleek carbon fiber chassis and twin 100-kw electric motors totaling 400 hp — enough to push the vehicle from 0-60 mph in 4 seconds flat, and to a top speed of 171 mph. GreenGT's head engineer Christophe Schwartz has stated that 'The GreenGT Twenty-4 design study could become our 2011 Le Mans Prototype electric racer, or it could even become an electric road-going supercar. There is a possibility to do both!'"

Maximum Prophet nods a NY Times piece on a Dutch group living the retro dream: they are trying to bring back Polaroid film. This group has the machinery to make the film packs, but needs to recreate the chemicals. Polaroid Inc. stopping making the specialized chemicals years ago, after having stockpiled what they would need for their last production runs. "They want to recast an outdated production process in an abandoned Polaroid factory for an age that has fallen for digital pictures because they think people still have room in their hearts for retro photography that eschews airbrushing or Photoshop. 'This project is about building a very interesting business to last for at least another decade,' said Florian Kaps, the Austrian entrepreneur behind the effort [in Enschede, The Netherlands]. 'It is about the importance of analog aspects in a more and more digital world. ... If everyone runs in one direction [i.e. digital photography], it creates a niche market in the other.'"

stevel writes "The owner of games site GamesByEmail.com created Dice-O-Matic, 'a machine that can belch a continuous river of dice down a spiraling ramp, then elevate, photograph, process and upload almost a million and a half rolls to the server a day. ... The Dice-O-Matic is 7 feet tall, 18 inches wide and 18 inches deep. It has an aluminum frame covered with Plexiglas panels. A 6x4 inch square Plexiglas tube runs vertically up the middle almost the entire height. Inside this tube a bucket elevator carries dice from a hopper at the bottom, past a camera, and tosses them onto a ramp at the top. The ramp spirals down between the tube and the outer walls. The camera and synchronizing disk are near the top, the computer, relay board, elevator motor and power supplies are at the bottom.' While not called out in the article, the pictures clearly show a Dell Mini 9 running the show (and performing the optical recognition of the dice values.) No, it's not running Linux."

vivian writes "Ever since 1996, when I first set eyes on a Sony GlassTron head-mounted display in Japan, I have been awaiting a lightweight, head-mounted display that actually has decent resolution and doesn't look like a brick tied to your face. The closest contender to date seems to be the WRAP 920AV from Vuzix, and they are partially transparent too, which is great, but as with every other unit I have found, they only offer video quality — 640x480. Given that there have been a number of other discussions on Slashdot, I can't be the only one here who is eagerly awaiting something that could actually be a viable alternative to a PC monitor — especially for gaming or 3d graphics work. Perhaps we could petition a manufacturer to make what we actually want? Something with a minimum of 1024x768 @30-60hz refresh, say, and capable of stereo vision. Extra karma if they incorporate head tracking."

An anonymous reader writes "A Piezoelectric Sound Level Meter was demoed at MIT's Battle of the Bands last month, borrowing its display from the do-it-yourself USB LED marquee that was the subject of a previous Slashdot story. This video tutorial describes in detail both the analog electronics plus the C code that runs the system. If this is your first experience at the intersection of digital and analog systems, don't be scared!"
