Cheap, energy-efficient ARM Cortex-M0+ may usher in the Internet of Things

By - May 9, 2012 2 Pictures
The newest entry in ARM's Cortex line, the Cortex-M0+ is claimed to be the world's most energy-efficient processor, delivering 32-bit performance on around one third of the typical energy requirements of an 8- or 16-bit processor. Targeting low-cost sensors and microcontrollers, the M0+ will come with a very modest price tag and could act as a crucuial stepping stone to a world in which everyday objects communicate with each other, sharing data to make smart, coordinated decisions that will improve our quality of life.

LaserSaber may not be a real lightsaber, but it sure looks like one

By - May 7, 2012 4 Pictures
I doubt there are many Star wars fans out there who haven't, at one time or another, fantasized about owning a lightsaber. These are the weapons favored by Jedi and Sith, resembling a sword but with a blade formed of colored light. To have one at your disposal is the dream of geeks everywhere; a dream that has edged closer to becoming reality with the LaserSaber. Read More

Soundlazer parametric speaker to enter production

By - May 4, 2012 13 Pictures
Sonic technology that allows audio to be specifically directed at a limited audience, as opposed to booming sound out as far and as loud as possible, has been around for a good many years but has yet to penetrate the mass consumer market. That situation could well change very shortly, however, thanks to the Soundlazer. The low-cost, pocket-friendly, open source, and completely hack-friendly parametric device developed by Richard Haberkern uses ultrasonic carrier waves to transmit sound from a connected music player on a narrow beam to a select listener.

Engineers produce multiple colors of lasers using a single material

By - May 1, 2012 1 Picture
Ordinarily, if you wanted to include blue, green and red laser light sources in the same device (such as a BluRay player), you would need to build in three separate lasers – each one incorporating different semiconductor materials. Now, however, engineers from Rhode Island’s Brown University have succeeded in creating different colors of lasers, all using the same nanocrystal-based semiconductor. Among other things, this opens the door to digital displays that could produce various colors of laser light simultaneously. Read More

Solidoodle 2 – the sub-$500 3D printer

For about a year, former aerospace engineer Sam Cervantes served as the chief of operations for Makerbot, the Brooklyn-based 3D printer manufacturer. While the reasons for his departure hasn’t been made public, his subsequent activities have – he’s been developing another 3D printer, known as the Solidoodle. He recently unveiled the latest model, the Solidoodle 2, which comes fully-assembled for just under $500. Read More

Front section of Boeing 737 recycled as superb flight simulator

By - April 25, 2012 21 Pictures
Like many computer users of my generation, I've notched up many hours of virtual flight time in a number of fairly realistic simulation programs. There are those who are simply not satisfied with keyboard, mouse and joystick control of jet fighters and passenger airplanes on a desktop computer system, though. Air traffic controller and pilot James Price is one such simulation-junkie who has taken his desire for realism to dizzy new heights by having the nose lopped off a veteran Boeing 737, fitting out the gutted cockpit with working controls, dials and monitors and then interfacing the hardware with flight simulation software. It's been a labor of love but we think the result is well worth the enormous amount of time and effort that's gone into the build. Read More

Self-assembling plastic nanofibers present cheaper alternative to carbon nanotubes

By - April 23, 2012 2 Pictures
French researchers have produced highly conducive plastic fibers with a thickness of only a few nanometers that self-assemble when exposed to a flash of light. The tiny fibers (one nanometer equals one billionth of a meter) could become a cheaper and easier-to-handle alternative to carbon nanotubes and play a role in the development of electronic components on the nanoscale.
