Various gadget/toy venues are writing about the Toyota Winglet, a diminutive Segway-like personal transporter. (Toyota took over Sony's robot division a year back.) It comes in three sizes and offers about a third the speed and a quarter the range of the Segway; on the upside, it charges in an hour vs. Segway's 10 hours. Wired writes: "The Winglet is the first gadget to duplicate the celebrated, and often mocked, navigation system of the Segway Transporter."

Ifandbut was one of several readers to point out the arrival in Oshkosh of the first practical jetpack. It was invented by a New Zealander Glenn Martin, who has been working on the idea for 27 years. He plans to sell the gizmos for somewhere in the neighborhood of $100K. While previous attempts at jetpacks have flown for at most a couple of minutes, Mr. Martin's invention can stay aloft for half an hour. Both "practical" and "jetpack" may need quotation marks, however: The device is huge and it's incredibly noisy. And, "It is also not, to put it bluntly, a jet. 'If you're very pedantic,' Mr. Martin acknowledged, a gasoline-powered piston engine runs the large rotors. Jet Skis, he pointed out, are not jets, and the atmospheric jet stream is not created by engines. 'This thing flies on a jet of air,' he said. Or, more simply, it flies."

Ubuntukitten writes "When some walls in Bocchignano near Roma started to erode, the perfect solution was found in Lego bricks (although some look suspiciously like Duplo bricks to me). FTA: 'At first I thought it would be a complicated procedure to fit the pieces, But as it turned out, the bigger plastic pieces were compatible with the smaller ones, and the Lego held itself in place without any glue whatsoever.' I like the effect. It's like the scene has been created on the holodeck but a few holoemitters are broken ..."

creyes123 writes "I run a free website with an online model airplane design calculator. The number of registered users has quickly climbed and I've gotten many compliments. Out of nowhere, a fellow shows up and proceeds to bad mouth the calculator in a posting in one of my forums. After I politely point out that he's mistaken and should have looked at the documentation before posting, he changes the subject and bad mouths a different 'flaw.' The cycle repeats a few more times, with no apparent end in sight. I want to encourage folks to share their opinions, but constructive criticism was clearly not his goal. I feel that the whole episode was just a massive time waster for me. What did I do to deserve this? Could I have handled this better?"

KentuckyFC writes "Earlier this year, Paris-based Aldebaran-Robotics picked up $8 million in venture capital funding to help commercialize its NAO humanoid robot. The target market for this device is research labs working on the next generation of robotic hardware and software. Today, the company has posted a detailed spec of NAO on the arXiv saying that it expects the robot to cost about $15,000 each. That's cheap compared to other humanoids. Fuitsu's HOAP humanoids cost $50,000 each and various estimates price Honda's Asimo at $1 million per bot, although they are not for sale. Aldebaran-Robotics says that NAO's cost should come down to about $6,000 as production ramps up."

Ponca City, We love you writes "A gun that fires variable-speed bullets that can be set to kill, wound, or just inflict a bruise is being built by a Lund and Company Invention, a toy design studio that makes toy rockets powered by burning hydrogen obtained by electrolyzing water. The company is being funded by the US Army to adapt the technology to fire bullets instead. The new weapon, called the Variable Velocity Weapon System or VWS, lets the soldier use the same rifle for crowd control and combat, by altering the muzzle velocity. It could be loaded with 'rubber bullets' designed only to deliver blunt impacts on a person, full-speed lethal rounds, or projectiles somewhere between the two. Bruce Lund, the company's CEO, says the gun works by mixing a liquid or gaseous fuel with air in a combustion chamber behind the bullet. This determines the explosive capability of the propellant and consequently the velocity of the bullet. 'Projectile velocity varies from non-lethal at 10 meters, to lethal at 100 meters or more, as desired,' says Lund. The existing VWS design is a .50 caliber (12.7 mm) rifle weapon, but Lund says the technology can be scaled to any size, 'handgun to Howitzer.'"

An anonymous reader writes "Gizmodo has a fascinating report and video tour inside the Lego factory, which is full of robots and controlled by a mainframe. 'This video shows something that very few people have had the opportunity to witness: the inside of the Lego factory, with no barriers or secrets. I filmed every step in the creation of the brick. From the raw granulate stored in massive silos to the molding machines to the gigantic storage cathedrals to the decoration and packaging warehouses, you will be able to see absolutely everything, including the most guarded secret of the company: the brick molds themselves.'"

jamie found the news that Tesla Motors is delivering roadsters in California. (We've been following developments on the Tesla front for a couple of years now.) According to a letter from the CEO, "9 production Roadsters have arrived in California, another 3 arrive this weekend, and they will keep arriving at the rate of 4 per week... In fact, currently there are 27 Roadsters in various stages of assembly." The early owners must be proud, but there could be complications.

My old keyboard was so crusted up with junk from years of abuse that I found myself struggling to depress most of the keys on the left side. So I decided that it was time to find a new keyboard. My plan was to steal the keyboards of my co-workers and try them out when they aren't around. But as this plan was underway, Das Keyboard asked me to review their newest keyboard. I used it for a few days to see if their website's claim of 'the best keyboard on the planet' is valid. Read on to learn more.

justechn writes "Many of us have seen robots in the movies and wondered how long it would take for them to become a reality. Some of my favorites when I was a kid were Short Circut and Runaway. iRobot is a company that is striving to bring some of that technology home today. Their most popular and well known product is the Roomba vacuuming robot. The Roomba is great, after I finished my review of it and sent it back I went out and bought one. It does its best work picking up pet hair. They just came out with another robot called the Looj. The Looj is used to clean the rain gutters that go around your roof. If you have ever had to do this by hand you know how much of a pain it is. This robot uses a 3 stage auger to break up clogs and sweep all the debris out of your gutter. It is also water proof so you don't have to worry if you have water in your gutter, just don't stand below it when it is cleaning or you will get sprayed." Read on for the rest of justechn's review.

An anonymous reader writes "Gizmodo has an exclusive video and feature of one of the most heavily guarded secrets in Lego: the security vault where they store all the Lego sets ever created, new in their boxes. 4,720 sets from 1953 to 2008. Really amazing stuff and a trip down memory lane to every person who has played with the magic bricks. All combined, the collection must be worth millions, not only because of the collector value, but also because Lego uses it as a safeguard in copyright and patent cases."

An anonymous reader writes "I'm an adult looking to learn how electronics work and have some fun building projects. But all the kits I've found online are for kids 8-10 years old, and they don't really explain the principles — they just color-code where to place components on boards. Are there any kits aimed at adults? I know if anyone has got the answer, it's this community."

afabbro writes "The current issue of BusinessWeek has an expansive article of the history of OLPC and why it has, to date, been a flop. Among the reasons: no preparation for the educational systems expected to use it, uncertain pedagogical theories, poor business management, competition from Microsoft/Intel, and no input from education professionals in designing the software. As BusinessWeek quotes one educational expert, 'The hackers took over,' and the applications are too complex for children to use. To date, 370,000 laptops have been shipped — a far cry from the original 150 million planned to be shipped by end of 2008."

mollyhackit writes "Here's a how-to guide for building a keyless entry that uses color identification instead of numbers. All eight buttons are initially blue; as you press the individual buttons they change color. Cycle the colors to your particular pattern, and you're in. This lock obviously wasn't designed for high security use since anyone in the same room would be able to see you and your amazing technicolor dream lock's pattern; it's just a fun project and will keep the youngins out of your workshop (timer prevents brute forcing). The RGB buttons are monome clones from hobby shop Sparkfun."

chrplace forwards an article in which Gartner's Brian Lewis offers his perspective on what led to last year's Xbox 360 recall. Lewis says it happened because Microsoft wanted to avoid an ASIC vendor. "Microsoft designed the graphic chip on its own, cut a traditional ASIC vendor out of the process, and went straight to Taiwan Semiconductor Manufacturing Co. Ltd., he explained. But in the end, by going cheap — hoping to save tens of millions of dollars in ASIC design costs, Microsoft ended up paying more than $1 billion for its Xbox 360 recall. To fix the problem, Microsoft went back to an unnamed ASIC vendor based in the United States and redesigned the chip, Lewis added. (Based on a previous report, the ASIC vendor is most likely the former ATI Technologies, now part of AMD.)"

Erik Johnson writes "I noticed something interesting tonight when re-tolerating that Guitar Hero: World Tour trailer and took a few screens, nothing solid of course, just some intriguing visuals on the alleged new guitars for the game. Whoever directed the commercial obviously had strict instructions to avoid having any clear shots of the guitar controllers. Get a closer look at the images."

Fallen Andy noted a Physorg story that says "Engineers and applied physicists from Harvard University have demonstrated the first room-temperature electrically-pumped semiconductor source of coherent Terahertz (THz) radiation, also known as T-rays. The breakthrough in laser technology, based upon commercially available nanotechnology, has the potential to become a standard Terahertz source to support applications ranging from security screening to chemical sensing." "What did you do at the office today, honey?" "Oh, I just demonstrated the first room-temperature electrically-pumped semiconductor source of coherent Terahertz radiation. How was your day, dear?"

stoolpigeon writes "IHT is running a David Pogue review of the Chumby. The Chumby is a small computer embedded in a soft case. The Chumby hardware and OS are open, and the review mentions that the device already has a large developer following, cranking out new widgets for owners. Pogue is obviously quite taken with the Chumby and gives a good introduction to a device that may be the inspiration for a new generation of hackers."

NotBornYesterday writes "After spending $190,000 and 'countless hours' building a set of jet-powered wings, a Swiss man has successfully demoed this ultimate mother-of-all-toys. After jumping from a plane like a skydiver, he then lit the four jet engines and proceeded to fly around a valley in the Alps at up to 186 miles per hour. His site is here, if you want to see shots of him in action. 'I still haven't used the full potential,' he said."
