There have been many attempts to create a mouse that doubles as a presentation device, borrowing designs ranging from pens to guns and often lacking along the way. But we've never seen one quite like this three-in-one device by a Chinese company called Vavolo. (Sounds like a motor oil company.)
It claims that the gadget is a mouse, a remote, a laser pointer and a keyboard (?)--that's four in one, not three--all housed in a slim design that can fit in a PC card slot for $40. It also looks like a large-button calculator for the sight-impaired, but … Read more
About a month ago, we wrote about the HomeStar Pro Planetarium, which uses LEDs to project the night sky on your ceiling. Here's another one for the astronomy buffs: Laser Stars, a projector that beams star and cloud formations onto your wall or ceiling of choice with laser technology and holographics. For those of us who live in brightly lit cities where we can't really see any real stars at night, it's a cool idea.
The Laser Stars projector looks to be less for nuts-and-bolts astronomy buffs than for people who just like to look at a … Read more
Finally, a mouse design that makes some sense. And maybe that's because it's not really a mouse at all.
The "Wow-Pen" seen on Chip Chick combines three features for which we have an undying appreciation: It's germ-free, includes an untethered laser pointer and has an ergonomic design that isn't weird. (After all, we started using quills this way centuries ago.)
Make that four features: It also looks pretty nifty and actually comes in colors that don't look like they came from a cartoon.
Growing up in the mid-Atlantic, I was subjected to watching more than a handful of squash matches back in high school. No offense to anyone who's an avid squash fan, but it's not always the most interesting sport to watch. You take people, and racquets, and balls, and a wall. There are a lot of smacking noises. Yawn.
But this is a little different. The creators of "Laser Squash" took the basic concept of squash and turned it into something that seems like it came out of a military training exercise in Ender's Game. Beams … Read more
The Blu-ray people face a big problem: those blue lasers are a pain to make.
Shimei Semiconductor has developed a blue LED grown on a silicon substrate, according to EE Times. Now, blue LEDs are grown on a sapphire substrate.
The prototype LED emits 450-nanometer wavelength blue light.
Shimei says it plans to start popping samples out for manufacturers in April. It is preparing production lines capable of churning out three million of these a month. Shimei will also examine the possibility of producing red and green LEDs with their technology.
