Zothecula writes "Because battery technology hasn't developed as quickly as the electronic devices they power, a greater and greater percentage of the volume of these devices is taken up by the batteries needed to keep them running. Now a team of researchers working at the Center for Integrated Nanotechnologies has created the world's smallest battery. 'It consists of a bulk lithium cobalt cathode three millimeters long, an ionic liquid electrolyte, and has as its anode a single tin oxide (Sn02) nanowire 10 nanometers long and 100 nanometers in diameter.' (Abstract in Science.) Although the tiny battery won't be powering next year's mobile phones, it has already provided insights into how batteries work and should enable the development of smaller and more efficient batteries in the future."

An anonymous reader writes "One of the zany hacker-makers here at MIT just finished this DIY Segway project (video). Difference from the others: it's all analog. The controller is built without a microprocessor or even digital logic. It does use a gyroscope like the real Segway. The functionality looks fairly basic, but the fact that the controller works at all is amazing. The guy has a ton of other projects on his site too. Definitely worth a read for people who enjoy building things."

destinyland writes "Fujitsu has built a device that can simultaneously harvest energy from either light or heat. They've reduced production costs by using the same cheap organic substrate for both conversion processes, while also doubling the potential amount of energy that can be collected. 'Previously, dual harvesting of energy could only be done by combining two different devices,' the article notes — and the device's solar converter can even draw energy from indoor lighting as well as direct sunlight. Fujitsu predicts the device will be especially useful for powering medical sensors, since the flexible substrate can be included in monitors which conform to the shape of the human body."

cylonlover writes "Cameras that can shoot 3D images are nothing new, but they don't really capture three dimensional moments at all — they actually record images in stereoscopic format, using two 2D images to create the illusion of depth. These photos and videos certainly offer a departure from their conventional two dimensional counterparts, but if you shift your view point, the picture remains the same. Researchers from Ecole Polytechnique Federale de Lausanne (EPFL) hope to change all that with the development of a strange-looking camera that snaps 360 degrees of simultaneous images and then reconstructs the images in 3D."

cgriffin21 writes "The Pentagon is taking matters into its own hands to prevent the occurrence of another WikiLeaks breach with removable media ban, preventing soldiers from using USB sticks, CDs or DVDs on any systems or servers. The directive prohibiting removable media followed the recent publication of more than 250,000 diplomatic cables, which were leaked to whistleblower Web site WikiLeaks at the end of last month by a military insider."

schliz writes "Arizona State researchers have been working on a 'self-healing' polymer that uses a fibre optic 'nervous system' to detect and fix cracks. The system recovers up to 96 percent of an object's original strength in laboratory tests. It could find use in 'large-scale composite structures for which human intervention would be difficult,' such as wind turbines, satellites, aircraft, or the Mars Rover."

blackbearnh writes "An article over on O'Reilly Radar makes the argument that, just as inexpensive or free software development environments have led to a cornucopia of amazing Web and mobile applications, the plummeting cost of 3D fabrication equipment could enable myriad new physical inventions. The article was prompted by a new Kickstarter project, which if funded will attempt to produce a DIY CNC milling system for under $400. Quoting: 'We're already seeing the cool things that people have started doing with 3D fab at the higher-entry-level cost. Many of them are ending up on Kickstarter themselves, such as an iPhone 4 camera mount that was first prototyped using a 3D printer. Now I'm dying to see what we'll get when anyone can create the ideas stuck in their heads.'"

siliconbits alerts us to the possible use of one of the world's most destructive naturally occurring scourges, the tobacco mosaic virus, to boost the capacity of lithium ion batteries by 10 times. It seems the virus can be made to attach itself to the electrodes in a lithium cell perpendicularly, increasing the surface area of the electrode and greatly improving the battery's capacity to store energy. PhysOrg has some more detail on virus-enhanced batteries. Four years ago we discussed the use of the tobacco mosaic virus to enable fast-switching transistors.

Meshach writes "Amidst all the angst about Google taking away the caps lock key from Chrome it now appears that is not the case. With one small change any user can change the Modifier Key from a Search key to a Caps Lock key. Peace has been restored..." If there must be such a thing as a Caps Lock key on conventional keyboards, I wish it could be banished (along with the Insert/Delete pair) to a hard-to-fumble-upon switch on the bottom of the keyboard or laptop.

sciencehabit writes with this except from Science: "You may not give a lot of thought to what happens inside the battery of your laptop or cell phone, but to judge from this video, it's not a dull place. The battery in question is a miniature rechargeable lithium-ion device, and the clip shows what happens when it is charged. As lithium ions flow from the positively charged cathode into the 200-nanometre diameter wires of tin oxide that make up the negatively charged anode, the nanowires writhe and bulge, causing them to expand up to 2.5 fold. The wires also change structure from a neatly ordered crystal to a disordered glassy material. These distortions may explain why such batteries ultimately wear down. Knowing more about the process may help researchers develop longer lasting, and perhaps much smaller, batteries in the future."

andy writes "After gentle prodding for about a year, my company actually agreed to include an electronics/robotics lab in the current build-out of our new office space. As I never really expected this to happen, I was at a bit of a loss when they asked me what sort of workbenches, equipment, etc. I wanted for the lab. The lab will only be approximately 9'x15' but there is a decent amount of vertical space to work with. I was thinking of having 2 workbenches side-by-side, one for 'hardware' and the other for 'software' with a floor-standing cabinet for storage. Semi-mobile workbenches might be a plus. Those of you that work in these sorts of environments, what do you recommend in the way of workbenches, storage, organization, and electronics?"

jones_supa writes "Leading PC companies have expressed their will to finally start kicking out legacy display interfaces. Intel plans to end support of LVDS in 2013 and VGA in 2015 in its PC client processors and chipsets. While the large installed base of existing VGA monitors and projectors will likely keep VGA on PC back panels beyond 2015, PC and display panel makers are in strong support of this transition. The DisplayPort connector interface provides backwards and forwards compatibility by supporting VGA and DVI output via certified adapters, while also providing new capabilities such as single connector multi-monitor support."

DMandPenfold writes "The UK government gave Chevron the go-ahead in September to drill in the North Sea off the coast of Scotland, in spite of the US oil giant's admission that its contractor's spill prediction software constantly crashed and was not a reliable predictor of how far oil could travel if an accident took place. The news comes in a week that US investigations into BP's disastrous Deepwater Horizon oil spill hit the buffers, after an IT contractor firm refused to hand over access to its software."

CWmike writes "Samsung on Tuesday announced a new 8GB dual inline memory module (DIMM) that stacks memory chips on top of each other, which increases the density of the memory by 50% compared with conventional DIMM technology. Samsung's new registered or buffered (RDIMM) product is based on its current Green DDR3 DRAM and 40 nanometer (nm)-sized circuitry. The new memory module is aimed at the server and enterprise storage markets. The three-dimensional (3D) chip stacking process is referred to in the memory industry as Through Silicon Via (TSV). Samsung said the TSV process saves up to 40% of the power consumed by a conventional RDIMM. Using the TSV technology will greatly improve chip density in next-generation server systems, Samsung said, making it attractive for high-density, high-performance systems."

angry tapir writes "Oracle will halve the number of cores in its next Sparc processor and instead improve its single-thread performance, a weak area for the chip but one that's important for running large databases and back-end applications. The next Sparc chip on Oracle's roadmap, the T4, will have eight cores on each chip, down from 16 in the current Sparc T3."

WesternActor writes "With its new Fusion APUs coming out in about a month, you wouldn't think AMD would still be tweaking its processor lineup. But it released three new processors today—the Phenom II X6 1100T Black Edition, the Phenom II X2 565 Black Edition, and the Athlon II X3 455—to balance out its price-performance offerings. The Black Edition CPUs with their unlocked multipliers are probably the most interesting, particularly the Phenom II X6 1100T Black Edition which has six cores, runs at 3.3 GHz, and costs only $265. As the name implies, the 1100T represents only a minute increase in clock speed over the 1090T. It even has the same amount of L2 and L3 cache (3MB and 6MB, respectively), is based on the same 45nm production process, and is designed for the currently standard AM3 socket. Given that 1090T got the downward nudge in price to $235, however, the 1100T offers slightly better performance for less money."

dcblogs writes "In a historic shift, shipments of smartphones, tablets and other app-enabled devices will overtake PC shipments in the next 18 months, an event that may signify the end of the PC-centric era, market research firm IDC said. IDC said worldwide shipments this year of app-enabled devices, which include smartphones and media tablets such as the iPad, will reach 284 million. In 2011, makers will ship 377 million of these devices, and in 2012, the number will reach 462 million shipments, exceeding PC shipments. In 2012, there will be 448 million PC shipments. One shipment equals one device. PC sales will continue to climb, but will no longer rule."
