Here’s A Security System That Does Absolutely No Securing

Most security systems/alarms do a very specific job: they detect forceful entry, sound an alarm, and contact the authorities. Yet, despite their existence, thieves are still plying their trade almost completely unhindered; it really doesn’t take a whole lot of time to smash a window, grab some things, and run. The LaserScan security system takes a different approach to the issue: deterrence. The system itself doesn’t do a thing. It doesn’t contact a security central, the cops or anyone. It doesn’t even detect unauthorized entry. All it does is look really menacing by projecting a set of moving laser beams all around the inside of your home. Seen from the outside, it looks to the robber like he’s not up against your run of the mill security system, but some kind of weird Hollywood-like setup. Will he be trapped inside? Gassed? Zapped? Who knows?! Better try the next house over. And a theft not attempted, is a theft not accomplished.

It’s $200 and we quite frankly believe it a better option that traditional systems out there. Until word gets out and the thieving community catches on. So, the ideal would be a combination of both: a deterring laser system that actually works. There’s a hole in the market here, folks…

This Meat Slicer Gets Equal Slices, Every Time, With Frikkin Lasers!

By David Ponce

Butchers are pretty masterful sometimes, but a human hand will never be as precise as a machine. And the above Natsune Libra 165C is one scary mother. It is able to make slices of meat that are of perfectly equal weight, every time, and it does so by using lasers. Yes, the lasers do the cutting. Big deal you say? Ok: it makes up to 100 slices a minute! First the uncut meat goes through their 3D laser scanner. Once the scanning is done, the machine gets to cutting; it ensures equal slices by varying the thickness of the slice, based on its initial scan and known densities of meat. While it could be used for several types of meat, it specializes in pork. Specifically (at least judging from the video) pork chops.

But the Natsune Libra 165C is clearly not the kind of machine you’ll have at home. Or even in a restaurant. It costs $160,000 for one. And it’s pretty darn big. We imagine that large scale meat processing centres would love them, and they’ll get their chance at ownership at the end of this month.

Ever Wonder What A Laser Tattoo Removal Procedure Looks Like?

By David Ponce

Half sleeve tattoo going away. 5 to 15 treatments and it’s a goner, they say. But looking at the above video, we’re left amazed at the technology’s abilities. It’s like removing stuff from a dry-erase board. We knew this existed, but seeing it being done for the first time it pretty impressive. And yeah, old video but we’re betting a lot of you have never seen anything quite like this.

Also, we hear it’s very, very painful.

FDA Approves The LipoControl Laser Fat Removal System Which Means It Probably Won’t Cut Your Arms And Legs Off

Last year we brought you the CoolSculpting system which disposed of fat cells under the skin by non-invasively freezing them. The LipoControl system is essentially used for exactly the same purpose, but uses the ‘pewpew’ power of lasers instead. To be specific, a 980nm laser diode is used to bust up fat deposits under the skin (it’s still an invasive procedure to a degree) but the system provides real-time visualization and feedback of the area being treated. It even tracks the speed of the doctor’s cannula, applying more or less power to the laser as they move it faster or slower so that it’s always at the optimal treatment level.

And since I’m no fatatician I don’t feel like I’m qualified to question how effective the procedure is, but it looks to me like after 3 months the machine has only really succeeded in adjusting that woman’s undergarments. Still though, if you’ve ever tried to adjust them yourself you know how difficult that can be and you’ll realize what an important innovation this really is.

AAXA Updates Their L1 Laser Pico Projector

By Andrew Liszewski

We only just posted our review of AAXA Technologies’ L1 Laser Pico Projector back in July, but already the company is introducing a 2nd version. If you missed our review of the V1, we pretty much summed it up as being the pico projector to beat not only because the laser light source produced vibrant, saturated colors, but the image was always in focus so you never had to worry about adjusting some wheel or slider every time you moved it.

Now the V2 doesn’t do much to improve the V1 when it comes to tech specs, it still kicks out 20 lumens at a resolution of 800×600, but the company has apparently improved the “thermal efficiency of the PCOS laser light engine.” On one hand it unfortunately means the L1 V2 is actually just a bit thicker than its predecessor, but on the other it also results in a price drop of $200 since the V2 now sells for $399.99, compared to the $599.99 price tag of the V1. Still not exactly an impulse buy, but it’s nice to see how quickly the prices are dropping with this technology.

Now you can finally bring home those laser-based animations that blew your mind at DisneyWorld or that last concert you went to with this laser projector from Chinavasion (~$110). It features a 70mw greeen laser that’s pre-programmed to draw one of several animated cartoons including such classics as the non-descript royalty-free version of Frosty the Snowman, a dinosaur fleeing extinction, a first year animation student’s headless walk cycle and the legless dancing girl. It can also project random patterns of squares, circles and lines if you just want to get trippy, and if you place it near a speaker the laser pattern can even react to sounds or music thanks to the projector’s built-in microphone.

Turn Your Old Computer Parts Into A Burning Laser

By Chris Scott Barr

If you’re anything like me, you’ve probably got old computers just lying around. You keep telling yourself that you’re going to repurpose them as some sort of media box, server or whatnot. But really they’re just cluttering up the back of your closet, or some corner of the garage. Today you’ll learn to put one of them to good use. You’ll fashion some of the parts into a laser capable of cutting through things. Why? Because that sort of thing is awesome.

You’ll just need a DVD burner (16x or higher) some heatsinks and the PSU from an old computer. There are a few other items you’ll need to get, but those are the main components. In a short while, you’ll be able to cut through small objects, and light others on fire. That’s right, you can burn those ants without needing to mess with a magnifying glass or depend on the sun. Just remember not to be an idiot.

OhGizmo! Review – AAXA L1 Laser Pico Projector

By Andrew Liszewski

Lasers, is there anything they can’t improve? Regular tag? Boring. Laser tag? Amazing! Regular pointers? Dull and ignorable. Laser pointers? Captivating! And it turns out that lasers can work their magic when it comes to pico projectors too. Last year I reviewed AAXA Technologies’ P1 Pico Projector, and the biggest gripe I had with it, and with every pico projector I’ve played with since then, was the fact that you had to constantly refocus the image whenever the projector was moved. And given they’re designed to be handheld most of the time, they move a lot.

Since the light from an LED tends to diffuse quickly, the image from an LED-based pico projector constantly needs to be refocused as you change its throw distance. But since the light from a laser has a high coherency and manages to stay very focused over long distances, the image from a laser-based pico projector never needs refocusing. In a nutshell it’s a clever solution to the issue I raised in my previous review. Now granted the technology isn’t perfect just yet, but as far as I’m concerned the new L1 from AAXA Technologies is now the pico projector to beat. And if you want to know why, you can find my full review after the jump.

Anti-Mosquito Laser Cannon

By Evan Ackerman

Welcome to the future, where your fly swatters and insect repellent have been replaced by auto-targeting laser systems. The “Photonic Fence,” designed by Intellectual Ventures Lab, is capable of detecting, tracking, and destroying mosquitoes in flight using basic components harvested from laser printers, Blu-ray disc writers, camcorders, and video game consoles. From the website:

The system would create a virtual fence made out of light— we call it a “Photonic Fence.” Light Emitting Diode (LED) lamps on each fence post would beam infrared light at adjacent fence posts up to 100 feet (30 meters) away; the light would then hit strips of retroreflective material (similar to that used on highway signs) and bounce straight back toward the illuminator. A camera on each fence post monitors the reflected light for shadows cast by a hapless insect flying through the vertical plane of light.

When an invading insect is detected, our software identifies it by training a nonlethal laser beam on the bug and using that illumination to estimate the insect’s size and also to measure how fast its wings are beating. Using this method, the system can not only distinguish among mosquitoes, butterflies, and bumblebees, but it can even determine whether a mosquito is male or female! (Females are significantly larger than males and have slower wingbeats.) This is useful because only female mosquitoes bite humans.

Our software is able to track a mosquito in flight once it establishes that it is a valid target. After running safety checks to ensure no unintended object is in view, the system activates a second, more powerful laser that zaps the mosquito, causing death either by damage to its DNA (an unconfirmed hypothesis) or by overheating.

So why lasers and not something more conventional like mosquito netting? Well, people in developing countries often end up using the netting to fish with, and anyway, a mosquito net doesn’t solve the problem, it just makes the problem go look for someone else to munch on. Pesticides can be damaging to local ecosystems and can harm humans as well. The absolute ideal way of controlling the spread of malaria is to target the mosquitoes and only the mosquitoes, and the Photonic Fence does a brilliant job of that.

By now, you’re probably spotted a few major hurdles… At this point, anti-mosquito laser cannons are a.) complicated, b.) expensive, and c.) in need of electricity. So obviously it’s not going to be a stand-alone solution, and it’s going to require some clever engineering to get it ready for field deployment. It required some pretty damn clever engineering to get this far, though, so I for one am optimistic. And I want one.
