My Homemade 40W LASER SHOTGUN!!!!!: An array made of eight parallel five watt lasers, a 'choke' made out of lenses, and a 250 amp battery create destruction from the
future a guy's garage. [slyt]

Every frame of "The New America" was laser engraved into a block of maple then photographed.
A few months ago there was a list of links to classic video game emulators posted. Very recently, I'm pleased to report, those links all came true. The Internet Archive bespoke upon aforementioned consoles, computers, and mileposts on our way to the tech utopia of today, (seriously, where's my flying car?) and they asked us to do something: Imagine every computer that ever existed, literally, in your browser. And it was so. I have absolutely no affiliation with jscott, btw. Thought I should disclose that.
How much data can you shove through a fiber optic cable? Quite a lot, as it turns out. Using the ITU standard 50 GHz dense wavelength division multiplexing grid, not only can you easily do 80 x 10 Gbps channels in a single fiber pair, but recent advances in modulation technology mean that with QPSK, 4QAM or 16QAM modulation, 1/80th of a dark fiber pair can carry a 100 Gbps signal in the optical space previously occupied by a single long distance 10 Gbps circuit.
Navy saves $1,399,000 versus short range missle. For the patient I particularly appreciate the appearance of R2D2, with modifications, at about 2:50 minutes.
light AMPLIFICATION - Is the color of future of your future neon pink? Is the language Japanese? Are the city's an eternal nighttime of airbrushed martini glasses, glossy red lips and consumer electronics? Do you jam with the console cowboys in cyberspace? Then this is the tumblr for you.

If every person on Earth aimed a laser pointer at the Moon at the same time, would it change color? No? *sigh* Well, what if we tried more power? Keep asking that question and you get an astonishing result.
The Curiosity rover is preparing to use its rock vaporizing laser for the first time, on a rock labelled as N165. Rock N165 has a twitter account. People are chatting to it.
WIRED has been running a fascinating series: Olympic Physics: Can Runners Benefit From Drafting?, Scoring the Decathlon, New [Swimming] Platform Is No Chip Off The Old Block [more inside]
Last year, the Heavy Air Laser Slalom regatta was run out of St. Francis Yacht Club in San Francisco. Organizers pick what they think will be a consistently windy day, and competitors race on the fastest points of sail. Here is some incredible footage. [more inside]
Laser Pointer Hack! A DIY guide to turning your laser pointer into a laser cannon.
Arduino + servos + laser + phosphorescent surface + Twitter = Fade Away 1. A thoughtful art project about the "permanence" of the Internet.
"Using the power of light, we have adapted our technology to address a problem related to an industry which is a crucial part of Scottish culture and economy." St Andrews University researchers have claimed they can work out a whisky's brand, age and cask by using a ray of light the size of a human hair.
Lasers made from living cells are a reality. Just a matter of time, then, before we're shooting laser beams from our eyes and fingertips.
A dramatic and surprising magnetic effect of light discovered by University of Michigan researchers could lead to solar power without traditional semiconductor-based solar cells.
Scheduled for November 25th, the Mars Science Laboratory - Curiosity Rover will launch on an 8.5 month journey to Mars. Upon arrival, it will plummet through the atmosphere in a flying-saucer-like aeroshell and execute a most unusual landing via skycrane. Curiosity carries a dizzying array of cameras and sensors, but more importantly a high powered laser to teach Mars who is boss, and oh, maybe your name if you let it.
Lasers 4, UAVs 0. It's easier to hit things at the speed of light. Raytheon tests a naval anti-aircraft laser, and you can watch it go at the link.
The "Laser Inertial Fusion Engine" (LIFE) is being developed at the National Ignition Facility. Stewart Brand blogs about its potential here and this video (.mov 128MB) is stunning. How LIFE works. Successful early test shots suggest that the NIF will achieve first nuclear fusion ignition within the next few months (+10 years to commercial).
The laser turns 50!, gallery, how Lasers work, more on how lasers work (in more detail than you can possibly want), 50 laser facts.
Here's a mostly working replica Star Trek Phaser. Original series, of course. Build pics and description here.
CyArk is a non-profit which makes three-dimensional scans of archaeological sites with lasers in effort to digitally preserve them. It currently has 27 projects, including Chichén Itzá, Angkor Wat, Anasazi Pueblos in Mesa Verde, Thebes, Rapa Nui and the Royal Tombs at Kasubi. There's quite a lot of material about Cyark online, including profiles Wired Science, a lecture by founder Ben Kacyra at Google as well as an article in Archaeology and an article by two CyArk employees in Professional Surveyor describing how they work.
Life imitates art. Boeing's Airborne Laser Testbed succeeds in shooting down a ballistic missile. No word on if popcorn was involved.
A baby star on Earth. The NIF (National Ignition Facility) is about to fire up lasers to demonstrate the real world possibility of nuclear fusion with a positive energy gain. BBC link with promo video narrated by Samuel L. Jackson. Also: previously.
Malaria is one of the world’s most serious health problems. No single approach has yet to fully conquer either the disease or the disease vector, the mosquito. The most common electronic means of killing mosquitoes, the “bug zapper” is not particularly effective. Using lasers to kill mosquitoes has previously been thought of as completely ridiculous. Now the concept is being taken seriously.
Jared Tarbell is a computer artist whose Gallery of Computation has been previously featured on Metafilter . Several years ago he began working with the Epilog Mini 24 laser cutter, cutting out flat cardboard pieces and assembling them into complex geometric shapes. His Flickr set “lased” documents his work. Recently he made the transition to a more traditional artistic medium; oiled walnut , for his stunning piece 2222 holes.
Laser pointer import ban in Oz Seems there's been a rash of people aiming laser pointers at planes in Oz. With an incident of a pilot being "temporarily blinded", this action may be a little less...well, as Oz politicians put it, "amusing". Previously. [more inside]
The LED Museum has long been the Internet's premier source of absolutely obsessive LED and Laser analysis. Going strong since 1999, Craig Johnson's amassed quite a range of test equipment. Recently, he acquired a Playstation 3 Blu-Ray Laser Module. Did he mod it? Oh yes he did. (Warning: NSFC64)
Holography For The Masses! A magical journey of making holograms with a $7.99 laser pointer and higher-power laser diodes.
The largest and most powerful laser facility ever designed is currently being constructed at Lawrence Livermore National Laboratory in Livermore, CA. I had an opportunity to tour this facility earlier this year, and the sheer magnitude of this engineering project is staggering. The precision required for ignition has been compared to "trying to hit the strike zone with a baseball from 350 miles away". Although the scientists and politicians responsible for the National Ignition Facility claim it will help lessen the danger of nuclear weapons, many critics argue it is merely an attempt to work around certain non-proliferation treaties.
Lightspeed is a fun little shareware game that I stumbled across today. It's one of those "bounce stuff off mirrors to light up stuff" puzzle games, but with nice graphics, and additional features like a level editor and such. Warning: windows only download, shareware fee to unlock many levels and features.
THIS is a light saber?!? "There really isn't anything out there, other than a baton and pepper spray, that can halt a dangerous suspect without doing him or anyone else harm," Herr said.
