Usually, device makers need to sign a confidentially agreement with Apple if they want to say their charger 'works with iPhone / iPod,' and they're not allowed to talk about how the insides work. If you don't put these secret resistors on the data lines too, you get the dreaded Charging is not supported with this accessory. We demonstrate how anyone can make their own chargers that work with iPhone 4, 3Gs, etc."

Barence writes "The most common complaint about 3D is that the glasses give you a headache, but that's not actually true, according to the man who teaches the pros how to make better 3D. Speaking at the BBC in London, Buzz Hays, chief instructor for the Sony 3D Technology Center in Culver City, California, explained: 'It's not the technology's fault, it's really the content that can cause these problems. It's easy to make 3D but it's hard to make it good — and by "good" I mean taking care to make sure that this isn't going to cause eyestrain.' He went on to detail some of the mistakes made by inexperienced 3D film makers, from poor composition of shots, through uncomfortable convergence settings, to overuse of on-set monitors without viewing their content on a big screen. But the biggest admission Buzz made was that not even the 'experts' know all the tricks yet, which is why 3D should only get better from here. In the same seminar, Buzz also explained why 3D glasses are here to stay — at least for the next few years."

josath writes "Texas Instruments' flagship calculator, the Nspire, was hacked to allow user-written programs earlier this year. Earlier this month, TI released an update to the OS that runs on the calculator, providing no new features, but only blocking the previous hack. Now, just a few weeks later, Nleash has been released, which defeats this protection. The battle rages on as users fight for the right to run their own software on their own hardware."

crimeandpunishment writes "A scientific expedition to the Titanic will create a detailed three-dimensional map of the world's most famous shipwreck. A 'dream team' of archaeologists, oceanographers, and other scientists will spend 20 days assessing the legendary ship's deteriorating condition, and collecting data and images. They're calling it the most advanced scientific mission to Titanic since its discovery 25 years ago. A leader of the expedition says this is the first time the wreck will be treated as an archaeological site, with two goals: 'One is to preserve the legacy of the ship by enhancing the story of the Titanic itself. The second part is to really understand what the state of the ship is.'"

adunk writes "Linus Åkesson has built an 8-bit synthesizer inside an old electric organ case. 'All the original tone-generating parts have been disconnected, and the keys, pedals, knobs and switches rerouted to a microcontroller which transforms them into MIDI signals. Those are then parsed by a second microcontroller, which acts as a synthesizer.' The Chipophone is perfect for playing classics such as the Super Mario Bros in-game music or Rob Hubbard's Spellbound. A description of the build process, with photos, is available."

Stoobalou writes "Sony has recently published patent applications which will allow two-player 3D gaming on a single screen. The new technology could spell an end to split-screen gaming, but is unlikely to see the light of day for a few years at least. Sony's method would allow player one to see frames one and three whilst player two would see frames two and four. Current technology requires a display with a 120 Hz refresh rate so it seems likely that we'll have to wait for 240Hz screen technology to become commonplace before two-player 3D becomes a reality. PDF versions of the two applications are available."

Deep Thought writes "Texas Instruments, already infamous thanks to the signing key controversy last year, is trying a new trick to lock down its graphing calculators, this time directed toward its newest TI-Nspire line. The TI-Nspires were already the most controlled of TI's various calculator models, and no third-party development of any kind (except for its very limited form of TI-BASIC) was allowed until the release of the independent tool Ndless. Since its release, TI has been determined to prevent the large calculator programming community from using it. Its latest released operating system for the Nspire family (version 2.1) now prevents the calculators from downgrading to OS 1.1, needed to run Ndless. This is TI's second major attack on Ndless, as the company has already demanded that websites posting the required OS 1.1 remove it from public download [PDF, in French], obviously to prevent use of the tool. Once again, TI is preventing calculator hobbyists from running their own software on calculators they bought and paid for."

radicalpi writes "Motorola has responded to claims that eFuse is designed to brick your device if you attempt to mod it or install unauthorized bootloaders. Yes, the device will still not operate with unauthorized software, but it will only go into recovery mode until you reinstall the authorized software. According to Motorola: 'If a device attempts to boot with unapproved software, it will go into recovery mode, and can re-boot once approved software is re-installed.'"

An anonymous reader writes with this excerpt: "Here are Photos/Pictures of my iPhone DSLR Prototype 1.0. This is my first attempt at putting together an iPhone DSLR. You might ask 'Why pair an iPhone 3G, iPhone 3GS, or iPhone 4 with a DSLR lens?' Why not!" Prototype or not, it's a cool project.

An anonymous reader writes with some discouraging news for hack-oriented purchasers of the new Droid X phone: "If the eFuse fails to verify [the firmware information (what we call ROMS), the kernel information, and the bootloader version], then the eFuse receives a command to 'blow the fuse' or 'trip the fuse.' This results in the booting process becoming corrupted, followed by a permanent bricking of the phone. This FailSafe is activated anytime the bootloader is tampered with or any of the above three parts of the phone has been tampered with."

ptorrone writes "A group of open source hardware makers have put together a draft of the open source hardware definition, now at version 0.3, which hopes to further define the making, sharing and selling of hardware within an 'Open Source Hardware license.' This fall, the day before Maker Faire New York City, the group hopes to have the license finalized for v1.0, and they are holding the first Open Source Hardware Summit. There are currently dozens of companies making open source hardware, altogether worth millions of dollars."

kkleiner writes "Aydogan Ozcan of UCLA has developed a microscope attachment for a cell phone – turning the device into a sort of mobile medical lab. It's both lightweight (~38g or 1.5 oz) and cheap (parts cost around $10). The cellphone microscope can analyze blood and saliva samples for microparticles, red blood cells, white blood cells, platelets, and water borne parasites. Ozcan and his team have recently won three prestigious awards for the device: a Grand Challenges award from the Bill and Melinda Gates Foundation (worth $100,000), the National Geographic Emerging Explorer award (worth $10,000), and the CAREER award from the National Science Foundation ($400,000). With these funds, Ozcan plans on starting case studies in Africa to see how the microscope can help revolutionize global medicine."

An anonymous reader writes "I'm starting a project that I hope that the engineers, makers and general DIYers in the Slashdot crowd can help out with. The full story's on the website, but the short version is as follows: my aim is to make a cheap, recycled, sustainable building, to document the process fully and to release anything that would help others to do the same. I intend to use an old train carriage as the shell, but the ideas should extend to shipping containers, aeroplane fuselages or anything similar. I know I'm not the first to do this, but I can't see anyone else who's provided a detailed step-by-step account of the build, complete with plans and the rest. Before I start, though, I'm trying to draw on as much collective experience as possible, and to head off mistakes before they happen. My question to Slashdot is simple: what do you think I need to know before I begin?"

Smerky writes "As I've been getting more and more into hobby electronics I have been finding it difficult to keep track of all the different ICs and other electronics that I have (resistors, capacitors, etc.). What are Slashdotters' recommendations for some inventory software? Certain qualifications that I'd be looking for personally are that it has to run on Linux/OSX well or be web-based (to run well on an Apache2 server)."

An anonymous reader writes "This week Dutch security researcher Niels Teusink described a method of attacking wireless presenter devices at an Amsterdam security conference. He had a demo showing how it is possible to use an Arduino and Metasploit to get remote code execution by sending arbitrary keystrokes to the presenter dongle. He has now released the code and made a blog post explaining how it all works. Better watch out the next time you're giving a presentation using one of these devices!"

An anonymous reader writes "Qualcomm today posted the source code to a Linux kernel driver for 2D/3D support on its OpenGL ES Core found on Snapdragon-based phones like the Nexus One. The company is trying to get this driver into the mainline Linux kernel, but it turns out that the user-space driver is still not open source, which has resulted in some problems already. The ongoing discussion can be found on FreeDesktop.org."

An anonymous reader writes "Here's an interesting new angle to the ongoing Flash-HTML5 debate. Digital Playground, one of the major adult film studios, said it would drop Flash today if all browsers were HTML5-ready (*cough*, IE8, *cough*). The company's founder said, 'Flash brings everything to a crawl and has an impact on battery life. With HTML5, there is no reason to show our content in Flash.' Digital Playground also indicated that it does not expect 3-D to gain mass acceptance any time soon."

An anonymous reader writes "The GPU for the Nintendo 3DS has just been revealed, and it's not made by Nvidia, ATI, or even Imagination Technologies. Instead, Nintendo has signed up Japanese startup Digital Media Professionals (DMP) in a deal that sees the company's PICA200 chip churning out the 3-D visuals. For the first time in Nintendo's history, the 3DS will feature a GPU with programmable shaders, rather than a fixed-function pipeline, meaning the 3DS is more graphically versatile than the Wii. Among the PICA200's features are 2x anti-aliasing, per-pixel lighting, subdivision primitives, and soft shadows. As well as featuring DMP's own 'Maestro' extensions, the PICA200 also fully supports OpenGL ES 1.1. The architecture supports four programmable vertex units and up to four pixel pipelines."

embolalia writes "An 80-year-old recording of a live radio broadcast featuring Thomas Edison has been uncovered and reconstituted. The recording was done on an obscure technology called a pallophotophone — Greek for 'shaking light sound' — that uses optical film to reproduce sound. The archivists who uncovered the canisters tucked away on a bottom shelf in a museum in Schenectady, New York (the city where Edison's General Electric was founded), did not have any machine to replay the films. Two GE engineers — working nights and weekends for two years — were able to construct a machine to replay the old tapes, recorded only two years before Edison's death." There's a video at the link, which may or may not contain some of the resurrected recording, but we couldn't get it to play from the Times Union site.
