Roof tiles change color based on the temperature, your house's mood

by Tim Stevens posted Oct 9th 2009 at 9:17AM

Okay, sure, ideally your entire roof would be comprised of solar tiles that would meet your entire house's energy demands and would also water your lawn and clean your gutters while they were up there. But, despite pledges of "affordability" something tells us it'll be awhile before your roof starts juicing your gadgets. This solution from MIT looks a little more practical -- and affordable. They're simply tiles that change color based on the temperature, Hypercolor style. In the cold they turn jet black, absorbing the sun's warmth and channeling that into the house. In heat they turn white, reflecting that same light and cutting down on cooling bills. Simple and smart. The MIT team calls the tech Thermeleon, and while early prototypes do change color as designed, it remains to be seen how durable the tech will be, and a leaky roof is no good regardless of how efficient. Asphalt shingles reign supreme for yet another year.

MIT's Bokode tech calls out zebra stripes, QR codes for battle of barcode supremacy

by Tim Stevens posted Jul 28th 2009 at 9:24AM

Since barcodes are the sign of the devil (must be true, we read it on the interwebs) it's no surprise that everyone wants to replace 'em. QR codes have been quite popular, allowing people and companies to tag their stuff with colorful decals filled with bits and bytes, and of course RFID tags are still going strong, but a team of researchers at MIT has come up with something better: Bokode. It's effectively a tiny little retroreflective holograph that is just 3mm wide but, when a camera focused to infinity sweeps across it, the Bokodes become clear and appear much larger, captured in the video below. In this way they can contain "thousands of bits" of data and, interestingly, show positional information too, meaning the camera knows where in 3D space it is in relation to the tag. This, of course, has hundreds of potential applications ranging from grocery shopping to augmented reality, and should lead to new and exciting ways for scholars to interpret/misinterpret Revelations.

New cuttlefish-inspired display tech can change color, eat your pet guppy

by Tim Stevens posted May 15th 2009 at 9:29AM

Cuttlefish are one of the most intelligent creatures in the sea, able to change their shape and color to escape predators -- but, they aren't smart enough to escape us, and they taste good, so they also go great with risotto. Scientists at MIT, however, decided not to eat their cuttlefish, instead using them to inspire the tech inside a new type of highly-efficient display. The screen is just one micron thick and contains a layer of poly-2 vinyl. Left alone it's clear but, when exposed to an electrical charge, its thickness and reflectivity can be controlled to create color. Just a few volts are required to form an image but, like e-ink, its design means backlighting is not an option. Viewing angles are also quite poor at this point, so this is one display tech that may take a long time to belly up at retail. Master of disguise video after the break.

Breakthrough in MIT's RealNose project could mean artificial noses for all - yay

by Stephanie Patterson posted Sep 30th 2008 at 4:47PM

The quest for the ultimate artificial nose is still underway, and thanks to a major breakthrough by the folks over at MIT, it might be sooner than later that we're all unwrapping stylish sniffers under the Christmas tree. More importantly, the fruits of MIT's RealNose project could replace drug and explosive-sniffing dogs as well as detect certain medical conditions via the odors emitted. Up to now, the tricky part of studying the sense of smell has been in isolating proteins (olfactory receptors) to get a good look at how they work. But in this latest development, researchers are now able to produce specific receptors using wheat germ. Engineered mammalian cells can be used to the same effect. What makes this so great is, while the human nose is relatively limited in what it can detect, this discovery could unlock the potential to detect an almost infinite range of odors. G.I. Joe with "action nose" here we come.

MIT's EMF detector bracelet takes all the fun out of radiation poisoning

by Stephanie Patterson posted Sep 22nd 2008 at 8:14PM

We've seen our fair share of EMF detectors and other tin foil hat apparel, but no endeavor is complete without the MIT stamp of approval. Cati Vaucelle's EMF sensor bracelet is designed to pick up on any potentially harmful electromagnetic fields, allowing you to dance around the veritable minefield of computers and cell phones in your workplace, unscathed by the -- maybe, maybe not -- lethal effects of radiation being emitted. Nevermind about looking like a freak -- better safe than sorry, right? The bracelet, sensitive up to 14-inches, features an integrated LED that's illuminated whenever an EMF field over 50kHz is detected. If you'd like to see this prototype in action, a video will be presented today at Ubicomp in Seoul, or save your air miles and see it here after the break.

MIT students automate dorm room, add "party mode"

by Evan Blass posted May 11th 2006 at 7:28PM

Even though they may have somewhat of a geeky reputation, MIT students party just as hard as the white hatters at your local state school, and probably graduate in larger percentages to boot. It should be no surprise, then, that a couple of dorm-dwelling party animals at the university decided to use their copious electronics skillz to convert their room into the ultimate cramped disco -- and because this is MIT we're talking about, everything goes live at the push of a single button. Using an X-10 control system, Zack Anderson and his roommate RJ Ryan hooked up strobe lights, black lights, a fog machine, laser light show, scrolling LED sign, disco ball, and an LCD projector to their computers so that all the effects would sync with whatever music was playing, and even retrofitted their window blind with a motor so it can drop down and act as a projection screen for some trippy visualization action. Calling their setup MIDAS (Multifunction In-Dorm Automation System), the pair also included a security alarm and camera for remotely monitoring their now-famous room, and situated small VFDs throughout the interior to deliver system status updates or other types of infoswag. Hey guys, if you don't land some hotshot jobs after college with your MIT degrees, we always have room for clever DIYers right here at Engadget.
