My quarry stops and looks around confused, but makes no effort to take cover. So I resume firing until my gun yells "Arrrrrrgh!", signifying a kill shot. The LED lights on my opponent's head flash red and he raises his gun into the air. This little tree is proving to be the perfect spot for ambushing attackers. I maybe kind of like pretending to kill people.

Today is BattleSFO, a day-long laser tag capture-the-flag tournament. The field of conflict is a hilly eucalyptus grove in San Bruno, CA, 45 minutes south of San Francisco, in Juniperro State Park. There are about 30 people here broken up into platoons of 5 to 7. Each player is dressed to the nines in varieties of camouflage, some with black war paint under their eyes. They're not quite as geeky as I had expected them to be. Then again, this isn't exactly the kind of laser tag everyone played as kids. The gear is bigger and badder, even if the players are not.

Almost the entire crowd of mostly men has never played laser tag outdoors before. For the most part they're very friendly, though a little shy when I ask them about themselves. One team is made up of four guys who went to college together — an electrical engineer, a carpenter, and an options trader. Another team makes up a local rock band (they seem more interested in drinking beer and running around the woods in battle gear then actually playing to win.) Then there's a group of three middle-aged Asian gentlemen and one of their sons who get together regularly and compete. They found the game on Meetup.com. Raymond Wan, who convinced the others to join him in the woods, explains that normally they play paintball. "The weapons and radio communication make a big difference," he says. "I'm a strategy person. This is more fun."

But among the beginners are some veterans of ray gun war.

The general of these mini-gorilla-armies today is Ziggy Tomcich. Earlier in the morning Tomcich performed his duties as the event's organizer, scurrying around the picnic table area, AKA central command. He's sort of a goofy guy, but his excitement was palpable and I couldn't help but giggle a little bit in anticipation of getting my hands on these fake guns and peering down the sight at some unknowing adversary. As I watched Tomcich untangle headsets, distribute color-coded headbands, and make sure everyone was checking in correctly it was clear that, though his day job is as an audio engineer for the San Francisco Opera, playing laser tag is his true passion in life.

Tomcich has been playing the game since he was a teenager. Running around the Photon indoor arena in Baltimore at 15, Tomcich got hooked. After graduating college he took a job as a designer, marketer, and consultant for several arenas around the country. Then, in 2006, Tomcich took laser tag to the next level. Playing in Armageddon games in the UK and Sweden, where players compete in 3-4 day tournaments, Tomcich played outdoor laser tag for the first time. When he returned to San Francisco, Tomcich realized that the city lacked the kind of gaming he really loved. Being outdoors and playing laser tag was something, he felt, everyone should do.

"To me, laser tag is an extreme sport," he says. For him, part of the fun and the reason why he started his event website SFLastag.org, is the idea that the game is simple to play and creates a highly social environment. "Unlike most other sports, first-time players in outdoor laser tag can do quite well against seasoned players. It's more about strategy and tactics."

Before the first battle "Cypher," aka Todd Robinson, who co-owns SpecOps Live Play, a central California company that provided the artillery, gave everyone a rundown of their equipment. SpecOps imports their guns from an Australian company called Battlefield Sports, essentially an arms dealer that deals in toys. The company custom builds 10 different models of gaming weapons from sniper rifles to sub machine guns – all equipped with real-world laser sights, speakers for feedback, and sensors to keep track of game stats. Guns can emulate any of 69 models down to recoil, and fire and reload rates and muzzle flashes (LEDs, essentially). SpecOps has brought M4 assault rifles, sub machine guns, carbine rifles, and sniper rifles.

During Robinson's speech, Tomcich chimed in: "Do not aim your gun at non-laser tag players. These guns don't exactly look like Hasbro." For this game every weapon has 99 clips of 50 rounds. Those with smaller guns reload in about 5 seconds, the bigger ones about 7-10 seconds, so Robinson recommended taking cover while reloading. "The ‘bullets' will bounce off of pavement," he says. For this game they've disabled friendly fire. But when they hit the laser targets velcro'd to heads that belong to enemies, the guns vocalize the action like weapons with built in sports announcers synthesizing current status of prey as "casualty", "killed" or "already dead".

As he went through the briefing, the look on Robinson's face was more serious then anyone in the eucalyptus grove. Listening to him describe each weapon and how they worked made it clear to me that, though some people are here to play a game, for others laser tag is a way of life. In other words, I better take good care of his guns.

Honestly, the weapons are a little intimidating. First off, they're huge and I'm, well, I'm little. The guns are so heavy, in fact, that I opted for the smallest one I could find. I was also one of two girls on the field. Cypher's father, who co-owns SpecOps, told me that women actually tend to fair better at this type of laser tag then men. Women, he said, will hang back and think tactically about the game. Guys sometimes have a tendency to run out out commando-style and shoot at everything they see. My tactics were set: I'd wait for my enemies to come to me.

The game starts and I take up position. When I shoot people that happen upon my trap, they stood still, look around, and fired recklessly without making much effort to take cover. Those I shoot over 20 times are killed, sent back to the respawn area (AKA Command Center, AKA picnic tables) where Robinson will reset them, reactivate their ordinance and send them back into the fray.

The battle heats up. Despite my overall aversion in life to things that require running and exercise, the real-world feel of this whole day is bringing up the competitor in me that normally only emerges when I'm shit-talking people during video games. It is unclear who is winning at the moment; the command center tracks the flag movement via new GPS-tracking system and the PC that also handles all the on field comms.

But no one is listening back at HQ. The General Tomcich isn't attending to the computer anymore. Instead, Tomcich's standing across from me in the grove defending our Purple flag from capture. "We're encountering heavy resistance," we can hear over the radio. "Wear them down," a player shouts. Minutes later our fellow Purple team members come running through the brush holding a flag. Our opponents are not far behind. But they're too late. This round is ours.

The Air Force and Boeing achieved a directed-energy breakthrough with these tests. MATRIX—Mobile Active Targeting Resource for Integrated eXperiments—performance is especially noteworthy because it demonstrated unprecedented, ultra-precise and lethal acquisition, pointing and tracking at long ranges using relatively low laser power.

I'm sure that description would get Governor Tarkin wet, but if that weren't enough, Boeing—along with the Air Force and the Army—also tested the Laser Avenger, a kinetic-laser hybrid weapon that fires a high power ray coupled with a 25mm machine gun.

Obviously, the kids in the funny uniforms are happy with their new toys, but I would like to see if they can do the same with a small thermal exhaust port only two meters wide. [Boeing via PopSci]

When you transmit information through turbulence—motion in the atmosphere caused by turbulent cells or "wind"—it's distorted just like the information coming from the light reflected off a distant, twinkling star to your eye. It's fuzzy. You have to overcome that by using adaptive optics to rectify the distortion and get a better quality signal.

That's what Dr David Hughes, from the US Air Force Office of Scientific Research, says. He claims that the technology has been tested successfully with both stationary and flying situations, which means that they can easily implement it in the battlefield, with not too much effort. [The Register]

The American Society of Plastic Surgeons is in an uproar about the things people are doing in their bathrooms. It's not that those surgeons are just worried about losing money on procedures, they're bound to gain clients from all the DIY messups anyway, but they appear genuinely concerned about regulations and safety. And I agree, because somehow former Gizmodo intern Benny Goldman letting the Jezebel team cajole him into a bikini wax doesn't seem so insane when you read about people ordering Botox from websites called Discount MedSpa and putting videos of their DIY injections onto YouTube (Warning: the clip may make you cringe).

We all like to look pretty, but there are safer ways to get rid of hair, folks! And somehow it's better to have wrinkles than order Botox from a website that looks like it was made in Microsoft Word. [Wired]

Just how long will we have to wait? There's no information on that, but we do know that Sharp is going through some testing of the devices:

Sharp has already verified the reliability of the new blue-violet semiconductor laser. It confirmed that the laser operated for more than 1,000 hours under the temperature of 80°C with a pulse width of 30ns and an output of 500mW.

Sounds safe enough to me, but sadly that stage is nowhere near actual products shipping. Let's hope they hurry up, especially since we've had the discs collecting dust for a year. [TechOn via electronista]

The spaser works about a thousand times faster than the fastest transistor, while having the same nanoscale size. This opens up the possibility to build ultrafast amplifiers, logic elements, and microprocessors working about a thousand times faster than conventional silicon-based microprocessors.

This new method treats light in a different way than traditional optical CPUs, which are "difficult to miniaturize because you can't contain photons in areas smaller than half their wavelenght." In other words: Optical CPUs won't fit in current electronics. Plasmonic devices, on the other side, can concentrate these nanoparticles in spaces similar to current processors. [Technology Review]

Experts warn that smoking doubles the chance of going blind in old age, so why not increase your odds with Kipkay's crazy (though admittedly awesome-looking) BIC-lighter hack. How-to video after the jump.

Kipkay is the gadget modder extraordinaire who showed us how to build our own laser-based home alarm system, save money on batteries, and turn a $25 Hot Wheels toy radar gun into the real thing.

He also has that enthusiastic shopping channel-style voice over thing down pat. I'll take two for my stoner friends!

No offense to the guy at preThinking, but there's a reason why Palm didn't make the back of their phone look like a ad or something you'd see at a NASCAR event. Leave Britney alone, as it were. [Prethinking]

That plan is called the Laser Synthitar. The DIY project combines a broken guitar (thought useless!) with three standard laser pointers (thought boring!) and a sound modulation system (thought deafening!). Combined, these technologies form the most promising defense against sharks with laser beams. But even if we still fall to the techno-aquatic beast, we'll do so while rocking. [Instructables via Synthopia via MAKE]

At the heart of the system is their special software that can automatically compensate for geometric distortion and track the movement of the pointer even when the USB camera is placed away from the projector. Getting set up appears to be as simple as plugging in the camera, and since the pointer can be used as a mouse, you won't need to use the laptop or a separate remote to control the presentation.

At $1,980, the Afterglow system certainly isn't cheap, but if giving dynamic presentations is core to your business I would figure that would be a small price to pay. [Afterglow via Gadgeteer via OhGizmo]

Possibly the most frustrating part of photography is the age-old trade off between light sensitivity and speed. Using a fast shutter speed means less light enters the camera, usually leading to underexposed, dingy images. However, by using new Serial Time-Encoded Amplified Microscopy (STEAM) technology, scientists have overcome these limitations.

The STEAM camera illuminates objects with an infrared laser that emits a different wavelength for each pixel captured. The camera's sensor then electronically amplifies the original, dim signal with a matching wavelength until it becomes visible.

Compared to the multi-million-pixel images produced by standard digital cameras, the current STEAM prototype only produces images composed of just 3,000 pixels. Yet there is a multi-megapixel camera in the works that the scientists hope will be competitive against consumer cameras. [Wired—Thanks Mark!]

Wired's Danger Room says that this won't be like Star Wars' blasters or Star Trek's phasers, but it can shoot "mortars and rockets" in war zones now. Two problems left to solve before we can start using lasers full time: how to dissipate heat and how to get them small enough to be practical. [Wired - Photo courtesy Northrop Grumman]

First, I'd like to commend the Wall Street Journal for what's probably their best headline ever: "Rocket Scientists Shoot Down Mosquitoes With Lasers." I hope whoever wrote it isn't too entertaining to keep his job there.

The project, started by Microsoft alum Nathan Myhrvold, is part of the effort to eradicate malaria in the third world, where it's a major cause of death. In testing the lasers, the researchers used an old Dell desktop to locate and zap the mosquitoes. The computer registered each successfully felled mosquito with a gunshot bang, which is how you know this is a fun experiment.

The problem now, of course, is how to kill or blind mosquitoes without killing people or harmless animals. Possible solutions include a range of lasers around a house or village that blinds the mosquitos, or even a plane that emits a sweeping motion of blinding light. The tech is so sharp that it can even tell a male from a female mosquito by the pattern of its wings; it's an important distinction, since only the females transmit malaria.

This is really a humanitarian effort we can get behind. And by get behind, I mean can I be part of the elite Anti-Mosquito Laser Task Force? [Wall Street Journal]

Seriously now: This is seriously fraked up. The ISS is almost as big as a Corellian corvette and it's up there defenseless, floating peacefully, sitting like a dinosaur-sized duck, waiting for one of the 18,000 pieces of tracked space debris to crack it open and take it down in a fiery ball of junk.

Sure, they have a escape spaceship for astronauts. In case things go bad—like they almost did today—they can jump in there and fly away before the worst happens. However, after all the money and effort put in the only human post in space, do we want to send everything to hell for a piece of orbiting crap? Wouldn't it be better to install defense mechanisms against space debris—or, ah, hmmm, alien ships!—to preserve the ISS?

Technically, there are already weapon systems that may be altered to perform this task, but this is not an easy task. We know it is not as easy as firing a laser and taking down the incoming chunk of metal with a Star Wars explosion.

There's a lot of things to be taken into account. First, you will need to detect the threat and fire from a very long distance, so the resulting effect doesn't cause any harm to the ISS itself. Then, the method to take down the object will change depending on its nature. Is it a big satellite or just a big chunk of metal from a previous collision? Does the incoming object have explosive elements inside? If the object is too big and can't be obliterated in a single shot, perhaps it would be better to have some kind of rocket that may approach the object and change its orbit by exploding near it? Perhaps some kind of emergency tug that can attach to the object and take it down?

We don't know. Whatever NASA and its international partner can come up with, they need to do it as soon as possible. Things are getting complicated up there, and this doesn't conflict with the international protocols against the militarization of space—which, in any case, are being constantly violated by the US, Russia, and China.

This will be a defense mechanism against space threats, and that's exactly what the ISS needs. It is just too valuable to be left there with no protection. NASA, it's time to get some pew pew action going on up there.

Small UAVs armed with explosives or equipped with surveillance sensors are a growing threat on the battlefield. Laser Avenger, unlike a conventional weapon, can fire its laser beam without creating missile exhaust or gun flashes that would reveal its position. As a result, Laser Avenger can neutralize these UAV threats while keeping our troops safe.

The Laser Avenger is mounted on the kinetic-based Avenger air defense system. However, no kinetic weapons were used in taking down the UAV. Tested at the White Sands Missile Range— a 3,200-square-mile rocket range in New Mexico, the largest military installation in the US—the Laser Avenger tracked three UAVs flying "against a complex background of mountains and desert", shooting down one of the UAVs.

The test success comes after the company doubled the laser power and added acquisition and tracking capabilities to the original design. Star Wars, here we go. [Via Press Release]

He got his done at NYC Resistor; if you remember our etch-a-fest at the Gizmodo Gallery thanks to Phil and friends from Make (among these, a sweet Epilog etcher), you know how cool these can turn out. This is one of the best I've seen—glossy black plastic really takes kindly to the laser's touch. [Kotaku]
