Want to learn how to win at pool and have your friends owe you pitchers of beer? Luis Sousa, Ricardo Alves, and JMF Rodrigues from the University of Algarve in Portugal have designed a solution that could have you sharking before you flash your toothy grin.

PoolLiveAid employs a ceiling-mounted camera hanging above the pool table that reads several different factors that will affect the angle of the shot: the position of the player, pool cue, table, and balls. It then calculates where your shot is likely to end up, mapping it onto the table with lasers. … Read more

Years ago, long before the dawn of the DVD or Blu-ray formats, consumer video was strictly all-analog, from the very first broadcasts right up to the introduction of the LaserDisc. The 12-inch, double-sided LaserDisc looked like a giant CD, but the video was analog encoded on two single-sided aluminum discs layered in plastic. The discs that debuted in 1978 had analog audio soundtracks, but later discs featured stereo digital sound. Millions of players were sold in the U.S., but LaserDisc was, even during the height of its popularity, a niche format that appealed mostly to videophiles. It had much … Read more

What are you going to do to mark the upcoming release of "Iron Man 3"? If you're superfan Patrick Priebe, you build your own Iron Man laser gauntlet.

As a 6-foot-tall, Mohawk-sporting hockey player, Priebe can come across as intimidating. His penchant for making laser weapons doesn't help much either.

His Web site laser-gadgets.com showcases his passion for the science fiction and video games, a passion reflected in his jaw-dropping creations -- guns that fire laser beams as well as laser-guided crossbows.

His latest creation is the Iron Man Laser Gauntlet, which fits over Priebe's forearm. It fires lasers, not anti-tank missiles. … Read more

The Light Marker for iPad is Griffin Technology's latest collaboration with Crayola to make more kid friendly products, and this gadget looks like it will be a hit.

For $29.99, you can get a glowing marker-shaped pen that interacts with your iPad's front-facing camera to let you freehand draw, paint, and color on your iPad screen. After touching the glowing tip of the pen to your front-facing camera you simply point the pen in the direction of the iPad (from a couple of feet away) to see a laser-pointer you use as your drawing instrument.

Directing the … Read more

Hewlett-Packard has launched a new printer that can serve as a hot spot, though it's available only in India and China for now.

The HP Hotspot LaserJet Pro M1218nfs MFP lets up to eight people hop on to wirelessly connect their mobile devices to the Internet.

As a multifunction printer, the device comes with the usual print, copy, and scan features. It also offers several options for printing wirelessly, including Apple AirPrint, HP ePrint, and HP wireless direct. HP's Smart Install tries to ease the burden of installation by letting you set up the printer without the need … Read more

Someday, somebody will bring an actual laser weapon to combat operations where it'll count. Until then, watch for more puttering about with the occasional field test of this or that prototype.

The latest manifestation of the eternal desire by the defense establishment for directed-energy weapons comes from Lockheed Martin, which yesterday brought word of its Area Defense Anti-Munitions (ADAM) system. ADAM's business end is a 10-kilowatt fiber laser that since August has been taking target practice against "representative" airborne threats.

The tally, it must be said, seems rather slight. Lockheed said that in the tests ADAM … Read more

The promise of laser weapons is that they will dispatch enemy missiles and other threats at the speed of light. Progress on those weapons systems, however, sure has been a heck of a lot slower.

When last we heard from Boeing about the HEL TD (High Energy Laser Technology Demonstrator) program in June 2011, the defense contractor had just finished system integration of key components, including the installation of the beam control system and other hardware on the 8-wheeled, 500-horsepower Oshkosh HEMTT (Heavy Expanded Mobility Tactical Truck).

This week, Boeing said that it's now engaged in the next phase … Read more

Here in Albuquerque, we have a 5-feet-to-pass law. You need to give cyclists that much room when you go around them in a car. It's easy to visualize when you have marked bike lanes, but some drivers push the limits on unmarked streets, especially at night.

If bicyclists carried their own bike lanes with them, it might help alert motorists to give them proper room. That's where Xfire's clever Bike Lane Safety Light comes in. The light uses two 5mW red lasers to create bike lane markings and five red LEDs for increased visibility overall. … Read more
