NASA Fires Lasers at the Moon to Track Lunar Reconnaissance Orbiter

NASA Fires Lasers at the Moon to Track Lunar Reconnaissance Orbiter

Yesterday night was the "International Observe the Moon Night," and obviously one large government agency probably took that to heart. And if you can't have fireworks to celebrate a day where you're supposed to stare at your favorite moon, why not lasers? NASA took the time last night to locate and track the Lunar Reconnaissance Orbiter, which is handled by lasers fired from Earth.

University of California Berkeley Researchers Create Portable Laser Backpack, Used to Map 3D Interiors

University of California Berkeley Researchers Create Portable Laser Backpack, Used to Map 3D Interiors

While Google is busy mapping out the exterior world, where all our streets and buildings are, there hasn't been much work on the interior part of the whole thing. But, considering the amount of security issues that may be red flagged in any kind of effort, it will probably be a few years before something like this portable laser backpack, which is used to create 3D maps of internal spaces, sees the light of day in the private market. But, that doesn't mean the Air Force can't get their hands on it.

Laser Used to Create Artificial Star 56 Miles Above Earth

Laser Used to Create Artificial Star 56 Miles Above Earth

Lasers. They can be used for a wide variety of things, or utilized in all sorts of methods, to create all sorts of different results. For all intents and purposes, lasers are the Jack of All Trades when it comes to high tech things that could be used as weapons. Or, in some cases, a good defensive tool. But, for one observatory and its researcher and scientists, they think a laser can be used to create an artificial star. And that's exactly what they're doing.

LucasFilm Retracts Cease and Desist Letter to Wicked Lasers

LucasFilm Retracts Cease and Desist Letter to Wicked Lasers

Wicked Lasers has been on somewhat of a roller coaster over the last month. Ever since they debuted the Wicked Lasers Spyder III Pro Arctic, people have been saying how amazingly similar it looks to the Lightsaber. You know, the one from Star Wars. Well, apparently a few folks over at LucasFilm thout it looked like a Lightsaber too, so they actually sent the company a cease and desist letter. Of course, Wicked Lasers subsequently put the letter on eBay, but that isn't the point. Today, though, LucasFilm has changed their mind, and retracted the letter from Wicked Lasers.

Mitsubishi LaserVue HDTV is 75-Inches of 3D-Readiness

Mitsubishi LaserVue HDTV is 75-Inches of 3D-Readiness

It's been a long time since Mitsubishi's LaserVue made an appearance in the real world. Something like 2008, if our checks are right. It could have something to do with that whole halt in production (which was thankfully temporary) which was announced earlier last year. We can happily announce that LaserVue is back on the scene, and this time around, it's touting 75-inches of 3D, HDTV awesomeness.

Laser Command game uses LED array for input as well as output [Video]

Laser Command game uses LED array for input as well as output [Video]

Oh Arduino, is there anything you can't do?  There's plenty to love about Eiji Hayashi's home-made Laser Command game: its palm-sized cube form-factor for a start, the simple 8x8 LED matrix display and its minimal controls, but it's the fact that you play the game by shining a laser pointer at the screen that really impresses.  Input takes advantage of the fact that the LED matrix can not only output light when current is applied, but output current when light - such as from the laser pointer - is applied.
