The International Consumer Electronics Show (CES) is a major technology-related trade show held each January in the Las Vegas Convention Center, Las Vegas, Nevada, United States. Not open to the public, the Consumer Electronics Association-sponsored show typically hosts previews of products and new product announcements.
Now in this post i am going to share who all the celebrities attending this great show:
Justin Bieber--Grammy-nominated platinum pop megastar, Justin Bieber, will be appearing with TOSY Robotics at this year's CES. Justin Bieber is helping TOSY unveil their new innovative entertainment robot.
Nicole "Snooki" Polizzi--Nicole “Snooki” Polizzi is best known for her role on the most talked about reality TV show Jersey Shore. She is a 4 foot 9 firecracker from New York who proudly shows off the lifestyle of being a guidette.

Washington, Jan 8 (ANI): An Arizonan engineer has come up with a wearable LED television that can be worn as a jacket and shows episodes of American animated sitcom, The Simpsons.
David Forbes, an electrical engineer by profession, was keen on building something really cool to wear at the Burning Man festival. So he re-purposed a comparatively simple flexible circuit board covered with LEDs.
He made the first with 30 rows of four LEDs each and then contracted a manufacturer to build 175 more of them. He attached them to an old coat and was able to build a display with a 160 x 120 resolution, which he notes on his blog is exactly half that of an iPod, Discovery News reported.
The set-up comprises a chip similar to that used in scaling down the images for security cameras , and another chip similar to the one used in controlling big LED signs used for advertisements. Forbes was able to put together his wearable display by adding a small set of circuits that convert video output of the iPod to the smaller resolution.
A full wrap-around display is priced at 39,995 dollars while a front-only will cost 24,995 dollars. Wait time is around four months. (ANI)

Technology is rapidly growing in the world.There might be some day in which things happen like self healing of electronics from damages due to temperature issues. The day is not so far..!!
University of Illinois engineers were able to create a method in which electronics with damaged circuits would be able to automatically repair themselves.The another shocking thing in this is that they are going to heal themselves with in 100 microseconds (100x10^-6 sec).
So in the upcoming years all the electronic gadgets uses this type of technology so that the gadgets will have long life and more durable.
The self healing technology involves creating circuits with gold lining and a layer of micro capsules. The damage for the circuits is mainly due to temperature effect. i.e circuits will get heated up and the heat will damage or cracks the circuit.
When such things happen due to temperature the microcapsules will automatically disperse themselves into the cracks, filling the gap and restoring conductivity to the circuit.
A group of scientists at Korea Advanced Institute of Science and Technology (KAIST) has fabricated a working computer chip that is almost completely clear, the first of its kind. The new technology, called transparent resistive random access memory (TRRAM).
The new chip is similar in type to an existing technology known as complementary metal-oxide semiconductor (CMOS) memory common commercial chips that provide the data storage for USB flash drives and other devices. Like CMOS devices, the new chip provides "non-volatile" memory, meaning that it stores digital information without losing data when it is powered off. Unlike CMOS devices, however, the new TRRAM chip is almost completely clear."It is a new milestone of transparent electronic systems," says researcher Jung Won Seo, who is the first author on the paper. "By integrating TRRAM device with other transparent electronic components, we can create a total see-through embedded electronic system."
"We are sure that TRRAM will become one of alternative devices to current CMOS-based flash memory in the near future after its reliability is proven and once any manufacturing issues are solved," says Professor Jae-Woo Park, who is Seo's co-advisor and co-author on the paper. He adds that the new devices have the potential to be manufactured cheaply because any transparent materials can be utilized as substrate and electrode. They also may not require incorporating rare elements such as Indium.
The fabricated TRRAM has a transmittance of 81% (including the substrate) in the visible region and an excellent switching behavior under3 V. The retention measurement suggests that the memory property of the TRRAM device could be maintained for more than 10 years. We believe that the TRRAM device presented in this work could be a milestone of future see-through electronic devices.
I think in future the iphone may be like the below image..!! :P
Intel may unveil its next generation of processors--nicknamed "Ivy Bridge"--in April, according to the latest reports. The Ivy Bridge chips for desktops and laptops promise a 37 percent performance increase over the current generation of Sandy Bridge processors.
The new Ivy Bridge CPUs use a 22-nanometer architecture, which makes them almost 30 percents smaller than the current chips, which use a 32nm architecture. Smaller chips mean lower power consumption (which is great for battery life) and more room for the integrated graphics chip. Ivy Bridge will support DirectX 11, Thunderbolt, and USB 3.0.
Taiwan-based trade publication DigiTimes reports that the first Ivy Bridge processors to launch will be quad-core desktop processors: the Core i7-3370 series and the Core i5-3570, 3550, and 3450. Because Ivy Bridge is backward-compatible with existing Sandy Bridge motherboards, desktop users should have an upgrade path available.
The first Ivy Bridge notebook chips to launch, according to DigiTimes, will be the Core i7 chips as well: The Core i7-3920QM, 3820QM, and 3720QM. Core i5 processors will pop up later.
Ivy Bridge will be smaller, more powerful, and more energy-efficient, and should be here in just a few months.

A Voltage Controlled Oscillator (VCO) is an oscillating circuit whose output frequency changes in direct proportion to an input voltage. VCOs can be made to oscillate from a few Hertz to hundreds of GHz. Every wireless device in use today has some sort of voltage controlled oscillator inside it. For example, there is a least one VCO inside every cell phone that generates the Radio Frequency (RF) waves that are used to communicate by-directionally to the cell tower.
Here today i am going to share Voltage Controlled Oscillator circuit using IC-555 timer.
It is basically an Astable Multivibrator circuit with variable control voltage.We know that internally set voltage at the control voltage terminal is 2/3 Vcc. In this circuit, the control voltage is externally set by the potentiometer. With change in the control voltage, the upper threshold voltage changes and thus the time required to charge capacitor up-to upper threshold voltage changes . Similarly discharge time also changes.As a result the frequency of output voltage changes.

Similarly discharge time also changes.As a result the frequency of output voltage changes.
If the control voltage is increased the capacitor will take more time to charge and discharge and therefore frequency will decrease. On the other hand if control voltage is decreased the capacitor will take less time to charge and discharge, increasing the frequency of output signal. Thus by varying the control voltage we can change the frequency.
