Extra dimensions don’t come cheap. If you’ve dreamed of a Sam Worthington-shaped avatar running through your living room, you know that 3-D projectors — the few that are available — have price tags in the $3,000-and-up range. (You also know that Avatar has yet to see a public 3-D Blu-ray release, but that’s another story.)

Optoma’s HD33 brings 1080p 3-D home for a 2-D price. At $1,500, it costs less than many 3-D-ready TVs, which, incidentally, can’t produce images as large as 300 inches. That’s 25 feet, in case you’re math-challenged. Eat it, local Cineplex!

Actually, don’t shred your concession-stand … [Read More...]

If you have to ask “Why?” then you just don’t get lasers

We’re sorry, but if you can view the brilliant green beam of the Wicked Lasers Krypton without going gaga with geeky excitement, then we have to question whether you have a soul inside. It’s a laser, people! It’s a handheld green laser that shines more brilliantly and fan-bloody-tastically than anything else you may ever point into the night’s sky.

The Krypton follows Wicked Lasers’ Arctic, a Class IV (read: dangerous) laser that caused considerable controversy last year. Both the Arctic and Krypton are 1-watt, Class IV lasers, but … [Read More...]

There’s a reason most cheap in-ear headphones sound that way: They only use one driver in each ear, which limits the audio range. If you want more life, more spaciousness and more oomph out of your favorite
tracks, upgrade to some dual-driver earbuds.

On these models, each earpiece contains two separate speakers— one to handle the high and mid frequencies, and one to handle the bass. This separation creates a more rich and filled-out sound that makes
any kind of music sound better. A dual-driver design is also especially good for listening to high-quality audio from lossless … [Read More...]

German software maker Ashampoo offers a wide range of system utilities and applications ranging from DVD burning software to 3D CAD tools. The only problem is some Ashampoo customers might be getting more than they bargained for. In a letter posted on its website, Ashampoo said that hackers gained access to one of its servers, stole customer names and email addresses, and have been sending out malware infected files to said customers.

On the bright side, Ashampoo says that no billing or credit card information was compromised, just names and email addresses. Ashampoo also said it discovered the break-in right … [Read More...]

Excel isn’t the sexiest application in the world–it has an unfortunate association with the type of Milton-esque office drones we all wish we weren’t.

Never bring a Maglite to a real flashlight fight

If you think the $25 flashlight you bought at Ace hardware is badass, think again. Today’s best flashlights are engineering tours de force, and even Moore’s Law has improved their performance with semiconductor advances.

There are three primary types of flashlights—incandescent, LED, and HID (high-intensity discharge). In our search for the ultimate flashlight, we eliminated incandescent as an option for this particular review round-up. Incandescents deliver value in the form of warm color temperatures in the 2,700-3,000 Kelvin range, but there’s just something wrong about a technology that hasn’t changed much in … [Read More...]
