Dodge Circuit EV test drive gets chronicled on video

by Donald Melanson posted May 11th 2009 at 2:24PM

We've already gotten a good look at the Dodge Circuit EV courtesy of the good folks at AutoblogGreen, but they've now come through yet again with a video that shows the Tesla competitor in action (or moving, at least). While it's expectedly still very much in prototype form, our fearless test driver nonetheless seems to have been fairly impressed by the car, with it delivering some speedy acceleration and an apparently generally pleasing ride. As noted earlier, however, the car is a tad cramped, and the real visibility leaves quite a bit to be desired, although Chrysler says that should be remedied somewhat by some smaller batteries in the eventual production version. Head on past the break for the video.

Ex-Seagate CEO joins startup Vertical Circuits, learns secret of the silver, gadget-shrinking ooze

by Ross Miller posted May 2nd 2009 at 9:51AM

Bill Watkins, the oft-outspoken former CEO of Seagate, has thrown his support behind tech startup Vertical Circuits, who claim to have an uncanny knack for shrinking gadgets with the power of voodoo -- or rather, a patented silver ooze, but we prefer our theories. The goo works as a replacement for gold wires to connect vertically stacked chips, cleaning up the internal cable clutter and leaving more room for better processor, bigger batteries, larger displays, or just a tinier form factor. Right now the focus is on stacking flash memory, but the group says they can use the same technique for processors and other chips. At this stage, there's no product or partnership to show for it, but if they're as good as they say, we hopefully won't have to wait long to see the fruits of their labor.

OE-A shows off nonvolatile RAM, RFID tag formed by printing

by Darren Murph posted Feb 27th 2009 at 3:30AM

While it's far from being noteworthy to the mainstream public, printable electronics hold a lot of promise. Over at Printable Electronics 2009 in Tokyo, the Organic Electronics Association (OE-A) demonstrated some of the most extreme, useful printings that we've seen to date. By utilizing an eclectic array of printing methods, the agency was able to produce nonvolatile RAM with a capacity of 1,024 bits (for use in ID and game cards) along with a printed RFID tag that could be launched today in logistics operations. We doubt very seriously that mere consumers will soon have access to printers of this nature, but if we can now print memory and wireless identification tags, one must wonder: what on Earth is next?

Brauswitch gives you eyebrow control, that Karate Kid look

by Darren Murph posted Feb 26th 2009 at 1:29PM

Forget controlling things with your mind, hands or feet -- how's about your completely underutilized eyebrows? Without any real output in mind, one Robert Carlsen designed the Brauswtich to give wearers the ability to control any number of things with just an eyebrow raise. Fully endorsed by The Rock, this apparatus contains a digital switch that can be activated when an eyebrow movement forces the tiny slit shut. Details behind the magic have yet to be revealed, but you can bet you'll see these infiltrating the likes of Spencer's Gifts, Hot Topic and Loose Lucy's when it's good and ready. Naturally, a demo video is after the break.

Flying plasmonic lens system could lead to denser chips / disks

by Darren Murph posted Oct 27th 2008 at 4:52AM

Last we heard, IBM was busy extending optical lithography down to 30-nanometers in order to keep Moore's Law intact, and some two years later, the process is still being honed by engineers at the University of California, Berkeley. Reportedly, gurus there with IQs far greater than ours have developed a new patterning technique (plasmonic nanolithography) that could make "current microprocessors more than 10 times smaller, but far more powerful." Additionally, professor Xiang Zhang asserts that this same technology could eventually "lead to ultra-high density disks that could hold 10 to 100 times more data than disks today." The secret to the madness is a flying plasmonic head, which is compared to the arm and stylus of an LP turntable; the setup enables researchers to "create line patterns only 80-nanometers wide at speeds up to 12-meters per second, with the potential for higher resolution detail in the near future." In layman's terms? That CPU you purchased last month will, in fact, be old hat in due time.

Integrated circuit turns 50, now isn't that nifty?

by Darren Murph posted Sep 13th 2008 at 10:17AM

Hard to believe that Jack Kilby's unsightly concoction (pictured above) turned 50 yesterday, but it's true. Half a century ago, Mr. Kilby crafted the integrated circuit, which ended up having a monumental impact on taking computers from warehouse-sized to, well, not-warehouse-sized. As the story goes, the very first microchip was demonstrated on the 12th of September in 1958, and it passed its first test: "producing a sine wave on an oscilloscope screen." Safe to say we all know how things progressed from there. Here's to you, IC -- and here's to 50 more.

Video: Furby Gurdy makes "music," trips you out

by Darren Murph posted Aug 25th 2008 at 3:36AM

The Nervous Squirrel's Furby Gurdy (version 2) isn't the first music maker we've seen that's better understood when viewed during an out-of-body experience, but it's certainly one of the strangest. The circuit bent Furby sequencer, which is linked to a Korg SQ-10 in the demonstration vid after the break, combines centuries-old musical methods with some of the strangest characters to ever grace planet Earth. We could talk for hours on end and still not do this thing justice, so just click through and mash play to see what we're referring to. We're warning you, though -- we haven't seen anything this weird since Smash Mouth's lead singer showed up at an Intel press event.

iPosture annoys you when you slouch, does so because it loves you

by Darren Murph posted Aug 19th 2008 at 6:47AM

Mama always said you'd regret slouching one day, and while you've still got a few decades left before ultimately determining whether the sage-like advice was right or wrong, why take chances? The iPosture does the same thing as wearable posture reminders that we've seen in the past, but this one does so in a much more discrete fashion. The diminutive nano-sensor detects when your angle deviates just three degrees from the optimal position for greater than a minute, after which it emits a warning to straighten you out. Users insistent on keeping it crooked can turn the device off by powering it down, removing it or flinging it furiously into a wall. Life's next big nuisance will be shipping soon for $99.95.

[Thanks, Eric]

Researchers get one step closer to all-nanowire sensors

by Darren Murph posted Aug 13th 2008 at 8:50AM

The latest in nanowire research has a crew at the University of California, Berkeley creating the very first integrated circuit "that uses nanowires as both sensors and electronic components." By utilizing a so-called "simple" printing technique, the researchers were able to create a batch of uniform circuits that could one day serve as image sensors. According to Ali Javey, an electrical-engineering professor at the institution, the goal is to "develop all-nanowire sensors" which could be used in a wide array of applications, and the benefit of using 'em is their exceptionally high level of sensitivity. In due time, the gurus would like to make everything on the circuit printable, though we have this strange feeling we won't be seeing any actual results from all of this for years to come.

DeepNote Guitar Hero bot reveals its secrets on video

by Darren Murph posted Aug 7th 2008 at 3:02AM

Don't even try to deny it -- you've been holding one mean grudge against that ridiculously accurate DeepNote bot ever since you saw it dominate Guitar Hero in mid-July. Really though, all that pent up aggression is completely unnecessary, and if you've been fruitlessly aiming to concoct one of your own, we've found the perfect place to start. The video posted up after the jump gives a fantastic overview of how the device actually works, and while it's far (very far) from simple, it's nothing the seasoned DIYer couldn't handle on an extended weekend. Give it a look if you're head over heels for PCBs and flashing LEDs (oh, and shameless rock 'n roll).

Networks of carbon nanotubes find use in flexible displays

by Darren Murph posted Jul 25th 2008 at 12:54AM

Carbon nanotubes may very well kill you (okay, so that's very much a stretch), but you'll have a hard time convincing the dutiful scientists at the University of Illinois at Urbana-Champaign to stop their promising research. Put simply (or as simply as possible), said researchers have discovered that "networks of single-walled carbon nanotubes printed onto bendable plastic perform well as semiconductors in integrated circuits." So well, in fact, that the nanotube networks could one day "replace organic semiconductors in applications such as flexible displays." Granted, there is still much to do before these networks are ready for product integration, but you can bet these folks aren't hitting the brakes after coming this far.

Another breakthrough purportedly brings us closer to quantum computing

by Darren Murph posted Jul 19th 2008 at 11:56PM

In reality, quite a bit of time has passed since we've heard of the next great leap in the (seemingly) never-ending journey towards quantum computing, but we're incredibly relieved to learn that at least someone is still out there, somewhere, pressing on. An international team of researchers have reportedly shown that they can "control the quantum state of a single electron in a silicon transistor, even putting the electron in two places at once." Essentially, the team is using tiny semiconductor transistors to "control the state of a quantum system," but there is still a long ways to go before any of this is meaningful. The crew managed to discover a few things by chance, yet to create a quantum computer, they would need to "position atoms of arsenic (or some other material) in the transistors more reliably." For those of you way too geeked out, fret not -- we'll let you know when all of this technobabble finally amounts to something.

Machine Collective reveals modular prototyping platform

by Darren Murph posted Jul 2nd 2008 at 11:10AM

While Bug Labs may have brought modular gadget kits to the forefront, you won't find us kvetching about yet another formidable opponent. Machine Collective has just launched a website to showcase its modular prototyping platform, which essentially consists of a number of interchangeable I/O modules "designed to work with development platforms such as Arduino and Wiring." Needless to say, the possibilities for DIYers and electrical engineers are pretty much endless here, though you'll have to "wait a few weeks" before excitedly beaming in your order and credit card information.

HP creates radical 'memristor' technology, brains explode

by Joshua Fruhlinger posted Apr 30th 2008 at 4:06PM

"Memristors" are one of several memory technologies that have been theorized and promised in the coming years. HP has made a real memristor, however, and the way solid state memory is created and stored could have just changed forever. First theorized in 1971, memristors are basic circuits like resistors, capacitors, and inductors. These circuits are able to store data by allowing their levels of electrical resistance to fluctuate between high and low, or 0 and 1 to a computer. Like flash memory, they retain that data without power -- except they do it all on one circuit and at the speed of D-RAM. In the end, we could be looking at a whole new kind of storage, as long as someone can figure out how to get these things onto integrated circuits. Nerds hats off, return to your fanboyism -- now.

IBM uses nanotechnology to craft miniscule art

by Darren Murph posted Sep 11th 2007 at 8:58AM

It's not like we haven't seen art on silicon before, nor is IBM any stranger to the more bizarre world of design, but the firm is nevertheless "touting one of the tiniest pieces of art ever made." The project, which consists of an "image of the sun made from 20,000 microscopic particles of gold," was reportedly "etched on a silicon chip wafer" with a process that managed particles some 60-nanometers in diameter. Of course, IBM isn't planning on entering the abstract art business anytime soon, but the achievement could purportedly pave the way for "high-performance transistors in molecular-scale chips" while "leading to a nanotech race inside IBM and rival companies."
