“IBM has revealed that graphene can’t fully replace silicon inside CPUs, as a graphene transistor can’t actually be completely switched off.
In an interview for a forthcoming Custom PC feature about chip-building materials, Yu-Ming Lin from IBM Research – Nanometer Scale Science and Technology told us that ‘graphene as it is will not replace the role of silicon in the digital computing regime.’
Last year, IBM demonstrated a graphene transistor running at 100GHz, claiming that the technology could be used to manufacture ‘zippy computer chips’ in the years to come. The story, along with news that researchers at the UCLU had produced a graphene transistor with a cut-off frequency of 300GHz, prompted all sorts of predictions of silicon marching towards its demise, making way for a graphene-based future with 1THz (one terahertz, or 1,000GHz) CPUs.
However, Lin says that ‘there is an important distinction between the graphene transistors that we demonstrated, and the transistors used in a CPU. Unlike silicon, ‘graphene does not have an energy gap, and therefore, graphene cannot be “switched off,” resulting in a small on/off ratio.'”
“Sure, lots of mice, ok, most mice can be coddled to work on fabric. But it takes a company with a dedicated mousing portfolio the size of Logitech’s to design a mouse specifically for use on the sofa.
See, the Logitech Wireless Mouse M515 features a sealed bottom case that lets you mouse around on soft surfaces without snagging.
That means it won’t collect bits of fuzz around the sensor when dragging it across the couch, bed, or a trouser-clad thigh. Naturally, it can also be used on more traditional computing surfaces, too.
The M515 boasts up to two-years of battery life thanks, in part, to a hand-detection sensor that causes the mouse to sleep anytime it’s not being held.”
“Corning, your scratch-free monopoly is coming to an end. No longer will you hold us hostage with your insanely durable and cunningly marketed Gorilla Glass.
Asahi Glass is getting in on the game, introducing Dragontrail — a name that doesn’t quite give us the same connotations of incredible strength but, if you watch the video, you’ll see it manages many of the same tricks as Corning’s offering.
Poking and prodding? Pass.
Huge flexes? Bring it.
Whacked with a hammer? Easy.”
“After the introduction of the smartphone, the industrial design of the devices has converged into all looking more or less the same.
Due to the touchbased interaction every smartphone device is now a flat rectangle with a screen on it, making it difficult for both the user and the manufactures to differentiate the devices from each other. This phone is trying to change that.
The unique form and unique way of interacting with it, is supposed to set it apart from other phones, but more importantly it’s supposed to add value for the user, making the experience of using a smartphone even more exiting and engaging.
The phone has 3 screens that can be transformed in different ways depending on what the user wants to do with it. Having 3 screens on a phone opens up a number of possibilities in dealing with the content on the device.”

“I needed a foot switch for my DSLR camera so that I could take hands-free pictures.
On a long-shot, I went down to the local Radioshack to see if they had one.
As expected, they didn’t have any camera foot switches, but I did luck out that they had all the parts necessary to build my own.
Here is how to throw together a 5-minute camera foot switch with easily obtainable parts from Radioshack.”
