Where To Start In DIY Electronics? 301

Posted by Soulskill from the hold-off-on-the-homebrew-lightsaber dept.
pyrosine writes "I've been thinking about this for a while and have no idea where to start. I have little or no previous experience in electronics — just what is covered in GCSE physics (wiring a plug and resistors — not much, I know). The majority of my interest lies in the wireless communication side of the field — i.e. ham radios and CB — but I am also interested in how many things work, one example being speakers, simply to better understand it. I would preferably like to start with some form of practical guide rather than learning the theory first, but where I would find such a walkthrough eludes me."

Companies Skeptical of Commercial Space Market 192

Posted by Soulskill from the come-on-it's-not-rocket-sci-oh-wait dept.
Hugh Pickens writes "The NY Times reports that Boeing and Lockheed Martin will happily sell rockets to carry astronauts into space, but are leery about taking a leading role in President Obama's vision for a revamped NASA that relies on commercial companies to provide taxi transportation to the ISS. 'I don't think there is a business case for us,' says Lockheed Martin's John Karas about space taxis. Both Boeing and Lockheed were stung during the last burst of optimism for the commercial space business about a decade ago. They invested several billion dollars — Lockheed to develop its Atlas V, Boeing for the Delta IV — in the hopes that the huge market for commercial satellites would supplement their traditional business of launching American military spy satellites. The market did not materialize, and what business there was went to European and Russian rockets that were cheaper. The hoped-for commercial market for space taxis hinges on one small company, Bigelow Aerospace, which is developing inflatable space habitats that it hopes to market as research facilities to companies and foreign nations looking to establish a space program."

Crowdsourcing the Department of Public Works 143

blackbearnh writes "Usually, Gov 2.0 deals mainly with outward transparency of government to the citizens. But SeeClickFix is trying to drive data in the other direction, letting citizens report and track neighborhood problems as mundane as potholes, and as serious as drug dealers. In a recent interview, co-founder Jeff Blasius talked about how cities such as New Haven and Tucson are using SeeClickFix to involve their citizens in identifying and fixing problems with city infrastructure. 'We have thousands of potholes fixed across the country, thousands of pieces of graffiti repaired, streetlights turned on, catch basins cleared, all of that basic, broken-windows kind of stuff. We've seen neighborhood groups form based around issues reported on the site. We've seen people get new streetlights for their neighborhood, pedestrian improvements in many different cities, and all-terrain vehicles taken off of city streets. There was also one case of an arrest. The New Haven Police Department attributed initial reports on SeeClickFix to a sting operation that led to an arrest of two drug dealers selling heroin in front of a grammar school.'"

MIT Researchers Harness Viruses To Split Water 347

Posted by Soulskill from the but-it's-harmless-trust-us dept.
ByronScott writes "A team of researchers at MIT has just announced that they have successfully modified a virus to split apart molecules of water, paving the way for an efficient and non-energy-intensive method of producing hydrogen fuel. 'The team, led by Angela Belcher, the Germeshausen Professor of Materials Science and Engineering and Biological Engineering, engineered a common, harmless bacterial virus called M13 so that it would attract and bind with molecules of a catalyst (the team used iridium oxide) and a biological pigment (zinc porphyrins). The viruses became wire-like devices that could very efficiently split the oxygen from water molecules. Over time, however, the virus-wires would clump together and lose their effectiveness, so the researchers added an extra step: encapsulating them in a microgel matrix, so they maintained their uniform arrangement and kept their stability and efficiency.'"

Google Rebuilds Docs Platform 194

Posted by Soulskill from the further-encloudificating-your-grocery-list dept.
mikemuch writes "In addition to offering faster, desktop-like performance, better imported document fidelity, and more features found in standard Office apps, Google's new infrastructure for its web-based office suite will enable the company to more easily update the apps. A side effect (or benefit, depending on where you sit) is that the new platform will ditch Gears in favor of HTML 5. For a while starting May 3 there will be no offline capability whatsoever. Collaboration is a big focus, with a new chat sidebar and real-time co-editing. The new Docs and spreadsheet apps will be opt-in previews, but a new drawing app is launching fully. Both go live later today on the Google Docs site."

Ubuntu on a Dime 531

Posted by samzenpus from the read-all-about-it dept.
AussieNeil writes "If IBM had adopted Unix for its Personal Computer and supported open source so *nix desktops were the now the norm, how hard would it be to convince the population to switch to Microsoft Windows? In Ubuntu on a Dime — The Path to Low-Cost Computing, James Kelly shows how easy it is to build a computer and install a complete software suite for US$200 excluding monitor, keyboard, and mouse. You can't even buy the operating system and anti-malware protection for Microsoft Windows for that, let alone have any money left over for hardware and productivity software! Then when you install the software, you have the paradigm of having to restart the computer to complete software installation and you have to learn how to practice safe computing while budgeting for annual anti-malware software license renewals!" Read on for the rest of AussieNeil's review.

US Rejects Demands For ACTA Transparency 351

Posted by Soulskill from the yet-we-still-see-right-through-you dept.
An anonymous reader writes "The US Trade Representative issued a release just prior to the launch of the New Zealand round of Anti-Counterfeiting Trade Agreement negotiations that has left no doubt the US is the biggest barrier to official release of the ACTA text. Unlike most other ACTA countries that have called for transparency without condition, the US has set conditions that effectively seek to trade its willingness to release the text for gains on the substance of the text."

Handling Money Brings Pain Relief Screenshot-sm 103

Posted by samzenpus from the nothing-wrong-that-$50-wouldn't-fix dept.
Psychologists at the University of Minnesota's Carlson School of Management have found that handling money can alleviate both physical and emotional pain. In one experiment, test subjects were found to feel less pain when their hands were dipped into scalding water after counting money. Lead author Kathleen Vohs said, "When people are reminded of money in a subtle manner by counting out hard currency, they experience painful situations as being not very painful. You could think about being able to charge yourself up before you encounter pain. When I used to run marathons, I would've maybe wanted to be reminded of money first."

Google Preparing iPad Rival? 397

Posted by CmdrTaco from the here's-hoping dept.
dazedNconfuzed noted an update in the ongoing rumor train about the Google iPad Competitor. It would be based on Android (not ChromeOS) and supposedly Eric Schmidt was telling people about it at a party in LA recently. If any Googlers want to leak me s3cr3t information, I promise anonymity, though without an actual product, price or date it's tough to get really excited. But the iPad clearly has significant limitations that someone else can capitalize on.
It's funny. Laugh.

Dirty Duty On the Front Lines of IT 166

snydeq writes "Jobs may be scarce in today's economy, but there's no shortage of nasty IT work — as the third annual installment of InfoWorld's Dirty IT Jobs series demonstrates. From the payroll cop to the coolant jockey to the network sherpa who has to squeeze into rodent-filled spaces and deal with penny-pinching clients, these seven jobs provide further proof that dirty duty abounds on the front lines of IT."

Do You Have a Secret Immunity To 3D Movies? 495

Posted by CmdrTaco from the also-they-hate-cilantro dept.
An anonymous reader writes "Not everyone who fails to be wowed by the latest Hollywood wave of 3D movies is necessarily criticizing the movie or the 'gimmick.' The author states: 'At least 12% of people have some type of problem with their binocular vision but less than five percent have severe visual disabilities, making appreciation of 3D tricky or impossible... For the 12%, two-eyed vision can be improved with supervised vision therapy. If anyone else out there, like I did, suspects 3D is a giant con, then perhaps a trip to the optometrist is due.'"

Hollywood's Growing Obsession With Philip K. Dick 244

Posted by CmdrTaco from the can-we-call-him-pip dept.
bowman9991 writes "Even after Blade Runner, A Scanner Darkly, Total Recall, Minority Report, Paycheck, Impostor, and Next, it appears Hollywood's lust for movies based on Philip K. Dick material continues. The Adjustment Bureau, starring Matt Damon, Emily Blunt, and Terence Stamp, is the latest, and features some classic Dick themes, including the fragile nature of reality and a fight against a world controlled and manipulated by powerful unseen entities. When Congressman David Norris meets the love of his life after a political defeat, he must peel back the layers of reality to discover why a mysterious group is so desperate to make sure they never meet again. He is up against the agents of fate itself — the men of The Adjustment Bureau. The Adjustment Bureau adaptation follows news that Terry Gilliam will adapt Dick's novel The World Jones Made, that Flow My Tears, The Policeman Said and Ubik are being adapted, and that a remake of Total Recall is being developed by the ironically named Original Films Studio."

Cell Phones Could Sniff Out Deadly Chemicals 136

Posted by timothy from the feature-creep-could-be-nasty dept.
Hugh Pickens writes "Science Daily reports that Homeland Security's Science and Technology Directorate's Cell-All is an initiative to equip cell phones with a sensor capable of detecting deadly chemicals. A chip costing less than a dollar would be embedded in cell phones and programmed to alert either the cell phone carrier to the presence of toxic chemicals in the air, and/or a central station that can monitor how many alerts in an area are being received. While one alert might be a false positive, hundreds would indicate the need for evacuation. 'Our goal is to create a lightweight, cost-effective, power-efficient solution,' says Stephen Dennis, Cell-All's program manager. Does this always-on surveillance mean that the govenment can track your precise whereabouts whenever it wants? On the contrary, DHS says; Cell-All will operate only on an opt-in basis and will transmit data anonymously."
