How to Turn a Flashlight Into a Laser (Video)



If you have an abundance of flashlights and a dearth of futuristic armaments in your house, then you'll want to take a look at what the weaponry wizards over at TechEBlog.com and Kipkay.com have for you. Without revealing whether the blueprints came from 'The A-Team' or 'MacGyver,' the video on Kipkay.com provides step-by-step instructions for converting a "regular mini-mag flashlight into a powerful burning laser." Requiring only the flashlight, a DVD burner, an Aixiz laser housing, a soldering iron, and a drill, the final product generates a laser, as demonstrated in the video, powerful enough to light a match or pop a balloon.

There is one negative, though. The how-to doesn't address how we're supposed to attach the finished laser to the head of a shark. Sorry, but we just couldn't help ourselves. Check out the video after the break. [From: Kipkay via TechEBlog]

Weaponized Lasers Coming to A Battlefield Near You...Eventually



Next time Dr. Evil asks his cohorts for a "frickin' laser," they just might be able to give him one; Northrop Grumman, a military manufacturer and defense systems developer, has successfully tested a 100-kilowatt (kW), electric laser for the first time. This weapon is far different from the mosquito-killing laser we talked about last week.

The development of this laser is significant because 100 kW is considered battlefield strength. The device consists of seven laser amplifier chains, each of which can produce around 15 kW of power. The development of a single, complete laser amplifier chain (which combine to form the foundation for more powerful lasers) had preoccupied scientists for a long time. Now that researchers have finally created a military-grade laser, they can focus on three major issues hindering mass production: size, weight and cost.

Once these futuristic weapons are smaller, lighter, and cheaper, we're betting they'll be employed by the U.S. military for defense against enemy rockets, aircraft, unmanned aerial vehicles, missiles, mortar rounds, and pretty much any other mechanized threat. [From: DVICE]

Scientists Shoot Down Malaria-Carrying Mosquitoes with Frickin' Lasers

Seriously, is there anything a laser can't do? A team of mad scientists in Washington have concocted a system that could essentially eliminate malaria-carrying mosquitoes with lasers, and the whole thing can be built from parts sourced on eBay. The so-called mosquito laser is credited to an idea from Lowell Wood, an astrophysicist who worked with Edward Teller, the "architect of the original plan to use lasers to shield America from the rain of Soviet nuclear arms." In theory, at least, the technology could one day be used to draw a laser barrier of sorts around a village. Of course, the trick is to make the lasers powerful enough to smoke the bugs without harming humans -- any of you Earthlings up for a clinical trial or two? [Via eHow]

Intel Shops at Sharper Image?

Intel Shops at Sharper Image?
So this may not be breaking news, but we're still wondering what on Earth made Intel decide that the Beamz laser harp was a good way to show off the power of the Core 2 Duo? (No idea what Beamz is? Check out the bizarre demo video here).

Why would Intel, a well-respected manufacturer and developer of high tech products, break out this over-priced pseudo-instrument that was even an embarrassment to Sharper Image? We've got to admit we hung out in the booth for a bit waiting for someone to blow us away with some bangin' Beamz beatz, but we came up empty.

Lasers Are the Only Way to Deal With Pirates, Says Homeland Security

Lasers - The Solution to All of Life's Problems
Despite what Homer would have you believe, beer is not the cause of, and solution to all of life's problems. According to homeland security analyst, James Jay Carafano, the solution to all life's problems is actually lasers.

Carafano, a PhD and Senior Research Fellow at the conservative Heritage Foundation, has been suggesting for years that the solution to just about every security issue we face is directed energy weapons (DEW) such as lasers and microwave guns.

In 2004, he suggested outfitting power plants and transportation hubs with lasers to defend against missiles. Then in 2005, he declared them the future of anti-terrorism technology. In 2006, he suggested that laser-based weapons could be used to destroy Hezbollah rockets. And as if his obsession wasn't obvious enough yet, in 2007 he argued for deploying such weapons on nuclear powered Navy ships and that the Russian-Georgian conflict highlighted the need for DEW systems.

Now, Carafano is suggesting that these weapons would be perfect for defending against pirate attacks in the lawless seas. He argues that even low-powered lasers would be effective at disabling the engines of small boats and detonating shoulder-fired missiles before they could be launched. In fact, it seems the only thing Carafano isn't suggesting we do with lasers is strap them to the heads of sharks. [From: Wired]

Military to Get Laser Weapons By Year's End


Note: We guarantee there will be no jokes about "freakin' lasers" in this article.

Now that we've got that out of the way, word is that the U.S. military will finally get weapons grade lasers by the end of 2008. No joke, the holy grail of a laser-based weaponry is right around the corner, according to Northrop Grumman, a military contractor. Grumman recently tested an electronic laser system that combines small silicon-based lasers into one more powerful beam, much like the Death Star. 100 kilowatts (kW) is generally considered the threshold for a useful weapons grade laser, and the most recent test only hit 30 kW. Since the weapon is built simply by chaining smaller lasers together,it will be able to quickly scale up its power by the end of the year, according to Grumman.

These new electric lasers have replaced traditional chemical lasers, which are bulky and require noxious gases to generate their high-powered beams. The size and danger of these systems has rendered them impractical for most military situations.

Grumman isn't alone, though. The military also expects to see a laser truck from Boeing and a laser mortar from Raytheon soon. Plus, it just test-fired its aerial Advanced Tactical Laser for the first time. It's only a matter of time before we'll all have ray guns and plasma rifles. [From: Wired]

Laser-Equipped Windshield Aims to Make Driving Easier


Apparently not everyone at General Motors is toiling away in an attempt to get the Volt ready for its 2010 debut, as another sector of the outfit's R&D division is busy creating a windshield that will, at its core, enable us to stop running stuff over. The futuristic glass would utilize lasers, sensors and cameras in order to help drivers see the road's edge better, recognize obstructions and enhance things ahead of us so we'll theoretically react faster.

Truth be told, the device is being designed with older drivers in mind, though we don't see why younger motorists won't benefit all the same. Unfortunately, it sounds as if you'll have to keep those toothpicks in your eyelids for a few more years, but at least we're one step closer to full-on autopilot. [Source: CNN]

Ravers Blinded By Laser Light Show Outside Moscow



Attendees at a July 5 music festival outside Moscow received more than a dose of sound as more than 30 people suffered injuries to their eyes from a laser show.

The festival (really a rave) was an outdoor event with DJ music and a laser light show. Due to poor weather, a canopy was erected over the dance floor, and the laser show, which should have pointed the lights up into the sky, instead was directed horizontally across the dance area and into the ravers' eyes. A recipe for disaster?

About 20 people are in treatment now due to significant loss of sight. And the treatment, according to a spokeswoman from Moscow Ophthalmological Hospital 'involves a lot of needles.' (Yikes.)

But just how does a laser damage eyesight? Can one of those pocket laser pointers really ruin your retina? Apparently, pocket lasers are set to only one-tenth the damage threshold, but can cause temporary 'flash blindness.' More powerful lasers (Class 4 and above) can cause damage, sometimes without a person even realizing it at the time. It is unclear what types of lasers were in use at the rave, but we wouldn't be surprised if they were just a bit more powerful than average normal pen-mounted laser.

Ravers at the event reportedly tried to capture video on their cell phones, but even that didn't work when the laser light overwhelmed the phones' cameras. No word on if the eyesight damage is permanent or how long it will last. [Source: CNN]

Laser Pointers Now Considered Controlled Weapons in Australia

Laser Pointers Considered Weapons in AustraliaIt seems the disturbingly common incidents we've seen in the US relating to improper laser pointer usage and the resulting arrests of those doing the pointing aren't exactly limited to the states. In Western Australia, such offenses have become so common that laser pointers have been classified as a "controlled weapon," meaning improper use could result in a $4,000 AU (about $3,700 U.S.) fine or 12 months in prison.

This change in classification comes after a series of incidents there similar to what we've seen in the U.S., where people of questionable intelligence have been caught pointing portable lasers at police and rescue helicopters, among other aircraft. Laser pointers, if shone into the eyes, at best can temporarily disorient the pilot and, at worst, can result in permanent blindness. That's no fun. We're no fans of arbitrary legislation against gadgets, but if that's what it takes to keep idiots from pointing these at aircraft, then we're on-board.

Laser Comb Claims to Cure Hair Loss

Another Laser Comb Claims to Cure Hair Loss

We've seen laser combs aimed at restoring lost hair before, but have not heard any inspiring tails of success. That hasn't stopped yet another company from jumping into the market for hair loss cures powered by the same technology that reads your DVDs.

The X5 Hair Laser is available only from that bastion of quality products, SkyMall. For $299, 15 points of laser light, supposedly optimized for stimulating hair growth, are focused on your scalp. A significant investment of time is required however to see any results. The company recommends three 10-15 minute sessions a week to see any results.

We suggest our friends with receding hairlines just go bald gracefully and not waste their money on gimmicky cures.

Though Big and Bulky, Mitsubishi's New Laser TV Dazzles

Laser TV from Mitsubishi is Unreal

The market for HDTVs is flooded with competing technologies and not to mention perplexing acronyms and abbreviations -- DLP, LCD, OLED, Plasma, SED. Now you can add Laser TV to your list of display technologies to know. Mitsubishi unveiled a 65-inch laser television at an event during this week's CES -- and people at this week's CES show were buzzing about the incredible color and contrast.

Mitsubishi isn't revealing details about exactly how it works, but we do know it is based on a rear projection system, meaning that this is never going to be as thin as those sexy OLEDs on display. And who knows what the future holds for big and bulky projection TVs, whose stars are falling almost as quickly as those of HD-DVD. But the laser TV does have a leg up in the image quality department. Apparently, colors were so intense and contrast so dramatic that Greg Adler at PC World described it as "artificial" looking.


Pricing isn't available, but Mitsubishi plans to have the displays on the market by fall of 2008.

New Lasers Help Combat AIDs and Hepatitis



Lasers, once reserved for such mundane tasks as shooting stormtroopers and taking out imperial Tie Fighters, are now being used for more practical (and safer) use in the medical field. New research has revealed a new technique that uses lasers to destroy viruses and bacteria -- including biggies like AIDS and Hepatitis -- without harming the cells of the infected person.

Physicists from Arizona State University are the ones behind the study, which was published in the Institute of Physics' Journal of Physics: Condensed Matter (what, you don't subscribe?). Beyond being a treatment for disease, the technique may also be effective in reducing the spread of infections such as MRSA in hospitals, say the researchers.

Lasers FTW.

Home Laser Comb Thickens Hair, Sort of...

Home Laser Surgery
The home laser revolution is upon us! It's not quite home surgery just yet, but medical lasers that help thicken hair, clear up acne, remove wrinkles, and remove excess hair are finding their way to a drug-store shelf near you. The effectiveness of the low-level or cool lasers is questionable, but many of new laser devices have received clearance from the FDA.

The products are very expensive, and their effectiveness is still a matter of debate. The HairMax LaserComb for instance costs $545. The comb must be used for 10-15 minutes a day, three days a week to be effective.

And after all of that, best case scenario is a 20% increase in hair thickness. (Sorry, guys, it's not going to give you back any lost hair or anything.)

Home lasers are here to stay, but don't expect a miracle.

Weirdest Techie Heists and Scams

    Elderly Amish Man Caught on Film With Prostitute, Blackmailed
    When a 75-year-old Amish widower slept with a prostitute, he -- we feel certain -- felt pretty bad about it the next morning. As if that guilt weren't enough for the old man, the prostitute and her boyfriend demanded $67,000 from him, claiming that they had filmed the scene with wall-mounted cameras and would upload the recording to the Internet. The pair was later arrested and, we can only imagine, the Amish man abhorred technology more than ever.

     

    Bank Robber Gets Away With the Help of Craiglist
    In October, a bank robber -- wearing a safety vest, blue shirt, face mask and goggles -- eluded police with the help of Craiglist. Just outside the bank, while the robbery was in progress, stood a group of men who were responding to a Craiglist day labor opportunity. As the advertisement required, they were all wearing safety vests, blue shirts, face masks and goggles.

     

    Nude New Zealander Arrested After Responding to Fake Sexy Text Message
    Late in 2007, a Wellington, New Zealand man received a racy text message from two anonymous "ladies," giving him only an address and a request that he show up naked. Well, he indeed showed up naked... at the home of one appalled, unsuspecting New Zealander. Both the nude Romeo and the sadistic texter were arrested, though neither were prosecuted.

     

    Fake Craiglist Ad Costs Man Most of What He Owns
    Last Spring, a post appeared on an Oregon Craigslist board stating that the owner of a specific house was leaving all of his worldly possessions (still in said house) to whoever wanted them. When homeowner Robert Salisbury rushed home -- on a tip from a woman suspicious about the offer of a free horse -- he found his house being ransacked by 30 strangers. We suggest he take that horse and collect some vengeance Clint Eastwood-style.

     

    17-Year-Old Jailed for Stealing Virtual 'Furniture'
    When a 17-year-old Dutch boy hacked into several accounts on the Second Life-style site 'Habbo' in 2007, the the law got involved. The boy was discovered to have stolen $5,800 worth of virtual furniture and knick-knacks. Apparently, crime -- whether actual or virtual -- does not pay.

     

    Phishers Going After Your Phones in New 'Vishing' Trend
    Over the past year, sneaky spammers have begun to forsake the worn-out territory of e-mail in favor of cell phones' fertile frontier. The result? "Vishing." Get it? Voice mail phishing. It might be more ominous if it didn't sound like a James Bond villain saying, "Wishing."

     

    Burglars Break Into Restaurant, Steal HDTV, Leave Money / Food Behind
    Around Halloween of last year, a truckload of thieves drove into -- that's right, into -- a Pennsylvania Mexican restaurant, where they -- apparently uninterested in the cash register -- stole a mid-grade 47-inch HDTV and fled the scene. We've all heard about how this generation is lacking in ambition, but this generation's thieves, too?
