There was a time when the world was more innocent and Lincoln Logs in elementary classrooms were a given, but now that teachers are looking to squash every ounce of fun between 8AM and 3PM (okay, so maybe we just had a rough experience or two), LEGO's taking the back door in. The WeDo robotics kit is marketed toward elementary schools and the younger kids within them, with each package containing 158 blocks, gears, levers, etc., a USB hub for connecting to your Mac / PC, OLPC XO or Intel Classmate, a motor, one motion sensor, one tilt sensor and a CD with a smattering of sure-to-be-riveting activities. Mum's the word on pricing for now, but considering your tax dollars will be paying for 'em, it's not like you'll really benefit from knowing.

Not that mad scientists haven't figured out a way to convert waste heat into energy, but a team from Ohio State University has developed a new material that does the same sort of thing... just way, way better. The new material goes by the name thallium-doped lead telluride, and at least in theory, it could actually convert exhaust heat from vehicles into electricity. According to a new report about to hit the journal Science, the material packs "twice the efficiency of anything currently on the market," though it still seems as if it's a good ways out from being ready for commercial applications. Nanotechnology geeks -- you've got a real treat waiting in the read link.

We're still a bit gun shy when it comes to surfing over to PEAK Surgical's website after watching that PlasmaBlade demonstration video, but a new release from the outfit affirms that said electrosurgery scalpel has just been approved for use by the US Food and Drug Administration. The "tissue dissection system," as it's so gruesomely called, has been given 501(k) clearance, meaning that PEAK can now market its tool for use in general surgery. So, anxious to camp out and be the first in the country to get sliced and diced by one of these? Bombard your local hospitals with phone calls starting next month.

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.

Intel's got big plans for Moblin, that Linux-based "core stack" that's being optimized for all sort of mobile devices, from MIDs to carputers, and a big part of those plans is letting the community play a part in its development -- the company is just about to release the source for the first version of Moblin, with an alpha-level release of Moblin 2 to follow. Intel says its focus right now is decidedly on Atom, but that it's looking forward to seeing the community drive Moblin in other directions. There's no word on what Moblin 2 will offer, but it sounds like Intel is hoping that by getting Moblin out in the open, it'll become a de facto standard. Not a bad idea, but we'll see how it goes.

We've seen quite a few induction-based "wireless power" systems make the scene, and while the idea is interesting both in theory and prototype, actually getting it to market has proven to be quite difficult, with some casualties along the way. That's why we're a little wary of new claims by Israel's Powermat, Ltd. that it's ready to go with tech that'll turn "any surface" into a power source. Well, that, and the PR image they sent us has the iPod charging screen Photoshopped onto every device pictured, including a first-gen RAZR and an N95. Oh, and they claim that embedding PowerMat in sheetrock eliminates the need for outlets entirely, but we're not at all sure how that's supposed to work -- do you have to hold your devices against the wall all night? Add to that the interesting claims that Powermat's tech delivers energy in "real time," and that it "completely eliminates the potential for electrical fires," and we're in full put-up-or-shut-up mode over here. Think you can top the wireless hamburger, Powermat?

We haven't seen all that many OLED lighting options, but a group of researchers from the University of Michigan and Princeton University say they could be on the verge of changing that situation, with them now boasting of a new breakthrough that could greatly increase the efficiency of OLEDs. The key to that, it seems, is a combination of an organic grid and some tiny dome-shaped micro lenses that guide the trapped light out of the devices. As the researchers point out, with current OLEDs, only 20% of the light generated is actually released, but they say this new method could boost the efficiency by a full 60%, or about 70 lumens per watt of power. Of course, they're also quick to point out that all of this is still quite a ways away from becoming practical for commercial purposes, although they seem to be optimistic that the eventual production cost for these new and improved OLEDs will be competitive with existing ones.

Nah, it's no Mag-Lite, but the Tri-Solar LED Flashlight should handle most minor lighting needs. The unit can operate with one LED on, three LEDs on or all three LEDs flashing (you know, in case you realize the car you just hopped in is now making a beeline for the Bates Motel). Because a single solar panel can only catch so much sunlight, this one has a trifecta of cells that fold out and generate juice for the bulbs. Not too bad for $32, particularly when you realize that it doubles as a weapon.

We're usually pretty jaded when people tell us that we "won't believe" what we're seeing in a video sent to tips -- right, right, a cellphone demon, nice one -- but it sure seems like the Golden Shellback waterproof coating is the real deal. Developed at the Northeast Maritime Institute and hopefully headed to production sometime soon, the process involves applying the coating to your precious toys inside a vacuum, after which they're basically impervious to all liquids -- in one test, a coated device spent over 450 hours powered on and functional underwater. There are some downsides: you can't remove the coating, so any repairs will involve "abrasive methods," which sounds like quite a commitment. That said, we'll take a little abrasion in our lives if it means we never have to worry about spilling on our keyboards ever again. Video after the break.

From all the coffee shop musicians here at Engadget, we'd like to sincerely thank Belkin for producing this marvelous device. For the rest of us who run around on stage like madmen, we have our doubts about how well this will work. Nevertheless, the BreakFree Connectors were designed to add a magnetic breakaway point in your 1/4-inch cable, meaning that things will simply snap away if too much pressure is applied. Sure, this could save you a mint in shredded cable costs, but we'd venture to say that only the calmer performers in attendance will really find it useful. Snatch (gently, of course) the BreakFree this September for $19.99 and grab a few extra tips for $9.99 per pair.

Check it, nerds. A team over at the Universidade Nova de Lisboa has reportedly figured out a way to use paper (yes, paper) as an interstrate component of a Field Effect Transistor (FET). In testing, the group "fabricated the devices on both sides of the paper sheet," thus causing the paper to act as the "electric insulator and as the substrate" simultaneously. Remarkably, results showed that performance actually rivaled that of best-in-class oxide thin film transistors, giving revived hope for the realm of disposable devices like paper displays, labels, intelligent packaging, tracking tags, etc. The findings are scheduled to be published this September, after which we're sure any firms interested in taking this stuff commercial will be putting their best foot forward.

We tried to take OCZ's Neural Impulse Actuator seriously, we really did. But unable to suppress those recurring images of Geordi La Forge, we simply couldn't help ourselves from having a laugh at this thing's expense. Nevertheless, the way-more-solemn dudes and dudettes over at HotHardware managed to give this brain-computer interface a fair shake, and overall, it was pretty impressed. Still, the bottom line is this: "the NIA is a very unique input device and possibly the first true brain-computer interface to hit the retail market," but it's not "a replacement for traditional input methods." Granted, critics did point out that it would supplement current devices quite well, but only after "slogging through" hours upon hours of training. The hardcore among us may be willing to put in the time necessary to really get a lot out of this; for everyone else, just continue to point and laugh while masking your ignorance.

Sure, we've been excited about Intel's Atom CPU being used in netbook-class devices, but UK ISP Bytemark apparently thinks the power-sipping chip has the horsepower to handle low-end server duties as well. For £45 ($89) a month, you can colo a 1.6GHz Atom box running Linux with 2GB of RAM and a pair of 100GB SATA drives -- not a terrible deal, and probably a damn sight more reliable than a pile of duct tape or a dead frog. Still, we're not exactly sure we'd want to run our business on the rough equivalent of an Eee 901, you know?

Let's say for some reason someone has his or her caller ID blocked and is calling you all the time. Let's then say you really want to know who that person is for, you know, whatever reason -- not that we'd know anything about that. Some crafty phreaker types have come up with a way to do this using an enterprise-spec asterisk box and a SIP trunk provider. In a demonstration video, a hacker tweaks said asterisk box with some new configurations to strip out privacy flags, forward the call to another number, and ultimately reveal caller ID information which, surprisingly, is still available. This isn't meant to be easy, but if the terms "prepend," "SIP trunk," and "asterisk box" don't scare you away, go ahead and watch the video after the break.
