AT&T WiFi hotspots free to iPhone owners, anyone with a brain

Filed under: ,


Now that AT&T has full control of wireless hotspots like Starbucks and Barnes and Nobles, it looks like they're doling out freebies to their favorite customers: iPhone users. Apparently, if you've got one of Apple's devices, you can hop on the WiFi networks for exactly zero dollars provided you enter your phone number at a login screen. Great for iPhone owners, but a raw deal for everyone else, right? Not so fast, apparently a dumb hack gets you the service on the house too -- just switch your browser's user agent to Mobile Safari, and presto! Free internet. We can't imagine this is a hole that won't get plugged real fast, so get it while the gettin's good.

Researchers tout progress towards graphene-based gadgets

Filed under: ,

We've heard researchers tout the many benefits of graphene before, and it doesn't look like they're showing any signs of letting up, with a group from the University of Manchester now boasting that they've made even more progress with the material that was created only a few years ago. Specifically, they've apparently found a way to develop graphene-based films (an alternative to the current indium-based options) more cheaply by simply "dissolving" chunks of graphite into graphene and then "spraying the suspension onto a glass surface." What's more, the researchers say that there are only a "few small, incremental steps" remaining before the graphene film is ready for the mass production stage, after which they say we could be seeing graphene-based LCD products within "a few years." As you may recall, this all follows some similar developments from researchers at the Max Planck Institute in Germany, although their method apparently "involved several extra steps," and they weren't making any promises about actual products turning up anytime soon.

Researchers design "malicious circuits," warn of potential risk

Filed under:

We've already seen a few viruses delivered via hardware, but a group of researchers from University of Illinois at Urbana-Champaign are now warning that we may not have seen anything yet. As New Scientist reports, they've apparently managed to develop their own "malicious circuits," which they say can interfere with a computer at a deeper level than a virus, and completely bypass traditional anti-virus software. To accomplish that slightly unsettling feat, the researchers created a replica of the open source Leon3 processor, and added about 1,000 malicious circuits not present in the original processor. Once they hooked that up to another computer they were apparently not only able to swipe passwords from memory, but install malware that would allow the operating system to be remotely controlled as well. Of course, they admit that sneaking such malicious circuits onto a chip isn't exactly an easy proposition, given that someone would either need to have access to a chip during its manufacturing process, or have the ability to manufacture their own. Or, as the project's lead researcher puts it, it's "not something someone would carry out on weekends."

SUNRGI, University of Tel Aviv boast of solar power advances

Source: http://feeds.engadget.com/~r/weblogsinc/engadget/~3/281649700/

Filed under:

It looks like we've got a bit of intercontinental solar power action today, with Silicon Valley start-up SUNRGI and the University of Tel Aviv both recently boasting of some advances in the field, which they each unsurprisingly say could change things in a big way. For its part, SUNRGI claims that its "concentrated photovoltaic" system (pictured above) can produce as much electricity as much larger solar panels thanks to its use of lenses that magnify sunlight 2,000 times. That, they say, could allow the system to produce electricity for as little as 7 cents per kilowatt hour, or roughly the same price as coal -- and as soon as mid-2009, no less. Not to be outdone, some scientists at the University of Tel Aviv say they've managed to create some super-efficient photovoltaic cells of their own that cost "at least a hundred times less than conventional silicon based devices." The key to their system, it seems, is the use of some good old fashioned photosynthesis, which they were able to achieve not-so-old-fashionedly with the aid of some genetically engineered proteins and a little bit of nanotechnology. As with SUNRGI, they're also promising to get the system out the door as soon as possible, with them reportedly aiming to get a "cost effective" 10mm X 10mm device produced "within three years."

Hitachi's 1.5 UltraThin LCD HDTVs now available in US

Filed under: , ,


You heard it right -- Hitachi's UltraThin 1.5 family that caused such a stir at CES is finally available for US consumers. Available in 32-, 37-, 42- and 47-inch sizes, the lot has been broken down into two distinct clans: the Director's Series (X) and Ultra Vision (V) models. Each member of the former comes with a 2-year warranty and a sticker ranging from $1,999 to $4,699, while the latter gets a 1-year warranty and price tags between $1,799 and $4,499. Curiously enough, it seems that several sets (the UT47X902, UT47V702, UT32A302/W, UT32V502/W, UT42V702 and UT37V702) may actually not yet be ready for shipping judging by their July to September availability dates, but we'll leave it to you to sort out the contradictions in Hitachi's press release with your dealer. Hit the read link for more details, and hop on over to Engadget HD for a gallery of press shots.
