wintersynth writes "We hacked a toy brainwave reader to electrocute people if their brainwave frequency got too high (by concentrating). We took outputs off of the 5 level LED indicator, put the outputs through a transistor/resistor/relay circuit to give 2 levels of high voltage through an electric shock circuit right into the user's arm."

So that's exactly what I did, three easy steps to converting your Rock Band drum kit into a wireless game controller, and using that to play online poker."

kkleiner writes "Skinput is a system from Carnegie Mellon's Chris Harrison that monitors acoustic signals on your arm to translate gestures and taps into input commands. Just by touching different points on your arm, hand, or fingers you can tell your portable device to change volume, answer a call, or turn itself off. Even better, Harrison can couple Skinput with a pico projector so that you can see a graphic interface on your arm and use the acoustic signals to control it. The project is set to be presented at this year's SIGCHI conference in April, but you can check it out now in several video demonstrations."

angry tapir writes "The Bluetooth 4.0 wireless specification could start to appear in devices such as headsets, smartphones and PCs by the fourth quarter, said the Bluetooth Special Interest Group. The new specification will be able to be used in lower-power devices than previous versions of the technology, including watches, pedometers, smart meters and other gadgets that run on coin-cell batteries."

andylim writes "According to Cellular News, researchers at Germany's Karlsruhe Institute of Technology have developed a method for mobile phones to convert silent mouth movements into speech. As recombu.com points out, the 'potential for secret conversations just got huge.' You could pass the time by making phone calls from the cinema without disturbing anyone. In noisy places like bars and clubs you could make yourself heard without having to shout."

HavanaF writes "Online backup is practical, but can it offer any privacy? The Dutch security company Safeberg developed an Offline Private Key Protocol, with an asymmetric key scheme. The protocol demands that the private (decryption) key be stored away from the 'source' computer, which presumably is 'too vulnerable.' The catch is that the private key needs to be fairly large to be secure: a 4,096-bit RSA key should suffice for some years. But how to store an 800-character key offline? Safeberg introduces a machine readable paper key, with the 4k-bit key crammed in a giant 2D Datamatrix barcode. This video on key strength tells the story."

Wael Chatila writes "By adding an on-board computer and a camera on a Roomba, the Roomba can be used to index your home. As a bonus, you can also control the Roomba across an internet connection, and see the images from the camera — a spybot for you to check on your own home while you are out."

magacious writes "Gtec has showcased a computer that can read your mind over at the CeBIT trade show in Germany. Designed primarily to help those who can't write or speak, the system makes use of a skull cap and wireless technology to transform brain waves into letters. It's the first patient-ready computer-brain interface, according to its Austrian makers. It takes around 30 seconds per letter for the computer to recognise what you're saying the first time you use it, according to Gtec, but this improves vastly with practice. '"One second per letter is very tough," Gtec's Engelbert Grunbacher said, adding users can usually easily get to five or 10 letters per minute. "You learn to be relaxed, focused. You improve."' It might look quite wacky (pictures here) and at €9,000 the system is not cheap, but it could help enhance the lives of many people who have a great deal to say but no real way of saying it."

DeviceGuru writes "LinuxDevices reports that a group of companies today unveiled — and demonstrated products based on — a tiny new PCI Express expansion standard. Although it's somewhat larger than the PCI Express Mini Card, the tiny new 43mm x 65mm FeaturePak card's high density 230-pin edgecard connector provides twice the number of PCI Express and USB 2.0 channels to the host computer, plus 100 lines dedicated to general purpose I/O, of which 34 signal pairs are implemented with enhanced isolation for use in applications such as gigabit Ethernet or high-precision analog I/O. While FeaturePaks will certainly be used in all sorts of embedded devices (medical instruments, test equipment, etc.), the tiny cards could also be used for developing configurable consumer devices, for example to add an embedded firewall/router or security processor to laptop or notebook computers, or for modular functionality in TV set-top-boxes and Internet edge devices." The president of Diamond Systems, which invented the new card, said "Following the FeaturePak initiative's initial launch, we intend to turn the FeaturePak specification, trademark, and logo over to a suitable standards organization so it can become an industry-wide, open-architecture, embedded standard" (but to use the logo you have to join the organization).

Several sources are reporting on the new offering from the British firm Pelikon which combines a touchpad and morphing keyboard into a unique little device. "This isn't just any old morphing keyboard, you see. Not only can the board be dynamically reconfigured by backlighting different portions of the keys — the entire surface of the thing doubles as a touchpad, which you can probably imagine has virtually limitless utility in a mobile device where the space for a true touchpad simply doesn't exist. Pelikon already works with Toshiba on its domestic-market Biblio, but we'd love to see it hit devices around the world — in fact, we wouldn't really mind if they just released this prototype they're showing as a Bluetooth accessory. diNovo Mini competitor, anyone?"

simpz writes "Will the serial port as a console connection ever be displaced — especially for devices such as switches, routers, SAN boxes, etc.? In one sense it's a simple connection. But it is the only current port that, in order to use, you need to know about wiring / baud rates / parity, etc. It has non-standard pinouts. And it is becoming too slow to upload firmware to dead devices, as the firmware updates get larger. Also, the serial port is rapidly disappearing from new laptops — which is where you often really need it, in data centers. Centronics, PS/2, and current loop are mostly defunct. Is there any sign on the horizon of a USB console connection?"

Go Rumors has discovered that Sony recently applied for a patent on a "universal game console controller." According to the patent filing, the controller "includes a hand-holdable housing and a touch sensitive liquid crystal display (LCD) on the housing. The LCD is caused to present, depending on what type of game console a user has selected, a controller key layout for a first type of game console or a controller key layout for a second type of game console. A key layout includes plural keys selectable by a user to input commands to a game console."

bugzappy notes a development out of the University of Oxford, where scientists have developed a technology capable of capturing a high-resolution still image alongside very high-speed video. The researchers started out trying to capture images of biological processes, such as the behavior of heart tissue under various circumstances. They combined off-the-shelf technologies found in standard cameras and digital movie projectors. What's new is that the picture and the video are captured at the same time on the same sensor. This is done by allowing the camera's pixels to act as if they were part of tens, or even hundreds, of individual cameras taking pictures in rapid succession during a single normal exposure. The trick is that the pattern of pixel exposures keeps the high-resolution content of the overall image, which can then be used as-is, to form a regular high-res picture, or be decoded into a high-speed movie. The research is detailed in the journal Nature Methods (abstract only without subscription).

Jax7 writes with this snippet from Technoholik, which dispatched a team with a video camera to get some early footage of the upcoming Android Tablet from Notion Ink, with Android and a Pixel-Qi transflective screen. Also interesting is the back-mounted touchpad. "We flew down to Hyderabad and caught up with the Notion Ink team just before they left for Barcelona to showcase the Android-based tablet tomorrow at the Mobile World Congress. Note that this product was 'one engineering day short' but we aren't complaining since we literally badgered them into giving us this sneak peak. The top panel over the screen was still a bit loose, so they took it off before booting the system."

theodp writes "While waiting to see if the iPad is a game-changer, this CS student continues to take class notes with pen and paper while her fellow students embrace netbooks and notebooks. Why? In addition to finding the act of writing helps cement the lecture material in her mind, there's also the problem of keeping up with the professor: '[While taking notes on a laptop] every five minutes I found myself cursing at not being able to copy the diagram on the board.' So, when it comes to education or business, do you take notes on a notepad/netbook, or stick with good old-fashioned handwriting? Got any tips for making the transition, or arguments for staying the course?"

The first X-Prize was about reaching space. Now, reader destinyland writes "This time it's inner space, as Peter Diamandis holds a workshop at MIT discussing a $10 million X-Prize for building a brain-computer interface. This article includes video of Ray Kurzweil's 36-minute presentation, 'Merging the Human Brain with Its Creations,' and MIT synthetic neuroscientist Ed Boyden also made a presentation, followed by discussion groups about Input/Output, Control, Sensory, and Learning. Besides the ability to communicate by thought, the article argues, a Brain-Computer Interface X Prize 'will reward nothing less than a team that provides vision to the blind, new bodies to disabled people, and perhaps even a geographical 'sixth sense' akin to a GPS iPhone app in the brain.'"

alx5000 writes "Engadget has a story about Displax Interactive Systems, a Portuguese company that has created a new polymer film that, when stuck onto a surface, converts it into a multitouch touchscreen with up to 16 contact points. The article states that 'if all goes well, the first Displax-enabled wares will start shipping this July.'"

An anonymous reader writes "A company claims it has the technology to make writing on touchscreens more like writing with pencil and paper, when the harder you press the thicker the line you produce. The technology uses a material called Quantum Tunneling Composite (QTC), the resistance of which is extremely sensitive to pressure, unlike today's touchscreen phones, which might be fine for basic finger-pointing, but they are poor at gauging the pressure of the touch. The hope is that this will be useful in Asia for handwriting recognition, because Asian scripts use a lot of variation in line thickness. Interestingly, screens with a standard 2D touch matrix can get the extra measure of control using a narrow strip of QTC down the side."

Bleep Labs, the same people who brought you the Thingamagoop (and now Thingamagoop2!), have released a new fun gadget — the Arduino-based Nebulophone. "What do you get when you mash together an Arduino-based synth with a Stylophone-like keyboard? A month ago, even we wouldn't have known, but now that Handmade Music Austin has come and gone, we're happy to say that this beautiful concoction leads to the creation of a Nebulophone. Unfortunately, there's no video (yet) to showcase what this musical wonder can do, but we're told that it has 'adjustable waveforms, a light controlled analog filter, LFO and an arpeggiator that can be clocked over IR.'"
