Some people are seriously considering what if the eurozone broke up. If some countries are departing eurozone abruptly, they don’t have time to produce new currency. It would need to find temporary ways to separate its share of the euros from the rest. One people suggested laser engraving.
… it to laser-engrave distinguishing marks onto the portion of the euros, which would have been allocated to the country departing the eurozone. This can be done relatively quickly and would make the currencies irreversibly different, said Mathes, adding “but I suspect that the European Central Bank will not look kindly on a state burning holes in its currency.
That would be good for laser companies in the crisis.
Hundreds of laser pointers have been seized by customs officials after a Sydney man allegedly tried to bring them into the country with him on a flight from China. – smh.com.au.
As a laser physicist, I investigate Physics in and with lasers, and develop new type of lasers. But I have never own a laser myself, not even a laser pointer. Recently, I got one from Techlasers. It is a Infiniti II 95mW, comes together with a dragon case and a goggle. It is slim and light, and take two AAA batteries to power. The beam is very clean and nice.
What I tried to do first is to take laser photos, as those cool people did. But it quickly turns out not an easy task. I pointed the laser to my fish tank. Poor golden fishes, I hope they were not frightened. But apparently, they avoid the laser beam well. They didn’t show up in my photos at all. All of my photos were blurred, because I took photo with one hand while another hand holds the laser pointer. I guess to really get good pictures I need kind of tripod for both my camera and the laser.
What do you think is in the following photo?
It is a bath towel. Interestingly, it looks deep, but actually flat.
Later I tried to point to objects like cups and bottles, etc, which are common subjects of laser photography. But the results are not as good as I have hoped. I need to learn photography.
I haven’t dare to point to sky or play outdoor yet, because I don’t know if there is any local regulation on usage of lasers.
WoodMarvels.com has just released an animation showing the assembly of a laser-cut bus that gets assembled in less than 43 seconds!
With close to 200 laser-cut, on demand projects to choose from, WoodMarvels.com has grown to become the largest provider of laser cut products in the woodworking industry thanks to an association with Ponoko.com. All projects are available as either blueprints (which you can cut yourself), laser-cut templates or pre-cut (with laser of course) kits. Another industry first, it has also begun producing custom soundtracks to accompany the 3D assembly animations.
Graffiti Research Lab’s [James Powderly] along with 9 other Tibet supporters were deported from China during the Olympic’s closing ceremonies. Detained on the 19th, the activists were to serve a 10 day sentence, but the Chinese government buckled under international pressure and deported them early. This brings the total number of deported activists to 53 since the start of the games.
Over Instructables, a guy shows how he used a laser etching mechine to tattoo himself. Such a crazy idea! Well, some people use laser to remove tattoo, while others use laser to tattoo…
He describes:
The sound by itself (meaning no body parts in the cutter), is probably the easiest thing to deal with. It is just the normal whine of gears, belts and cooling fans. When that sound is mixed in with the sensation of burning flesh, it turns the laser cutter from a simple machine shop tool to a futuristic torture device.
The sight is not too bad, just a light tracing its way back and fourth across the body. As long as you don’t think about the fact that the small wisp of smoke trailing the light, is actually vaporized skin, everything will be fine.
The smell is bad. It does not travel far, but when you catch a whiff of the burnt flesh stench, it is quite nauseating. The thought that you have just inhaled some of those vaporized skin flakes, and they have settled on the bottom of your lungs, is the worst.
