Hasta La Gadget!

We’ve performed some very careful, scientific research on the movement of sunflowers that one time on lunch break where we stared at a sunflower for four or five minutes, and let us tell you: it’s pretty boring. Mix in robotics, however, and things start to get a bit more interesting — no roasting required. Himawari the robotic sunflower, developed at Kyushu University in Japan, is a bit of interactive art which can track people with an IR camera, point itself in their direction and blink on its LED lights if they wave hello. Not exactly at the forefront of robot research, but it is pretty dang cute. An adorable video is after the break.

If you’re down with the latest freshness, like we know you are, you’ll already be aware of light writing and the radical imagery that can be created through the use of long camera exposures and stop motion animation. Well, get ready to do your thing with even more style, thanks to the Halo LED spraycan — a DIY project by Aissa Logerot — which not only looks like the primary tool of al fresco art, it even recharges itself when shaken. While not quite as sophisticated as the Light Lane, this definitely makes our list of light-based paraphernalia we’d like to see more of. You’ll find a few more shots after the break, plus a video of a well-known ad campaign featuring the light writing technique.

As we’ve seen with the slight resurgence of new and improved incandescent light bulbs, the amount of energy used to actually light up the bulb isn’t necessarily the whole measure of energy efficiency. There’s also the small matter of producing the bulb, shipping it around the world, and eventually disposing of it. With that in mind, the Siemens Corporate Technology Centre for Eco Innovations conducted a study that compared regular compact fluorescents to LED lamps — using one 25,000-hour LED lamp as a constant, compared to 2.5 10,000-hour compact fluorescents (and 25 1,000-hour incandescents). While it’s still holding back on some of the finer details, the group did apparently find that LEDs are no more or no less energy efficient than compact fluorescents when the entire lifecycle of the bulb is taken into account, although it is quick to point out that LEDs should eventually win out as they become more efficient to produce.

Study says LEDs are about as efficient as compact fluorescents, all things considered originally appeared on Engadget on Wed, 05 Aug 2009 05:03:00 EST. Please see our terms for use of feeds.

Sure, we might all just be getting used to LED-backlit LCD HDTVs, but this train ain’t stopping, Chico — Samsung just got official with the 8500 series, which features the next-generation of local-dimming LED backlights. The 54.6-inch and 45.9-inch 240Hz sets are just 1.6 inches deep and offer a 7,000,000:1 dynamic contrast ratio, a 2ms response time, and an Energy Star 3.0 savings mode that continually adjusts the picture and backlight to optimize both picture quality and power savings. You’re also getting Samsung’s usual suite of connected TV features, like the Yahoo! Widget Engine, DivX playback, and DLNA support, but you’ll be paying handsomely for all this newness — the 45.9-inch UN46B8500’s MSRP is $3,599, while the 54.6-inch UN55B8500 will run you $4,499.

Yeah, mad scientists have been trying to get the public at large to pay attention to visible light communications for years now, but the gurus over at the University of California, Riverside think that the project they’re involved in holds a special kind of promise. The Center for Ubiquitous Communication by Light (UC-Light) will be funded with $3.5 million from the Multicampus Research Program and Initiatives (MRPI) competition within the University of California system, and at its core, it’s hoping to unearth a magical method for linking up all sorts of electronics (HDTVs, PDAs, information kiosks, PCs, etc.) via light. You know, so your refrigerator can tell your smartphone what groceries are needed during the next supermarket stop, and that massive billboard on I-95 can beam more information that you don’t want right onto your handset. If all goes to plan (and California’s budget problem solves itself), the work will begin in early 2010 and last five years, after which we fully anticipate “very low-cost communication and navigation systems [to be built] on existing lighting infrastructure.” And fowl in every pot. And unicorns in every garage.
