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.
Designer Eugene Cheong brings you “Maestro,” laser and mp3 guitar learning aid. You put mp3s into the device via SD card, the songs are converted into guitar tablature, and the tablature is projected, with laser lights, onto the guitar fretboard as you play.
The system utilizes a ceiling-mounted laser pointer, an I/O bridge with servo module, two servos, a webcam, an X10 module and a buzzer. When the buzzer sounds, the dog is alerted that it is time to play. Using the iPhone, the user can turn the lights on and off and move the laser around the room for the dog to chase. When you have finished damaging your dog’s mind, the buzzer can be sounded a second time to indicate that playtime is over.
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.
