Acer Aims To Be World's Top Computer Maker By 2011

Posted: 29 Nov 2010 08:07 AM PST

Acer, currently the second largest computer maker in the world is aiming to be the top computer manufacturer in the World by 2011.

"If the mobile world continues to grow, we will necessarily replace HP as the world's biggest computer-maker," CEO Gianfranco Lanci told the SonntagsZeitung in an interview

Not only the computers market, the company is also aiming to capture the mobiles market in big way. The company is planning to sell over a million mobile phones in the coming year.

Currently HP is the world leader in computer manufacturing.

Do you think Acer will replace HP?

Rugged PCs Required To Meet The UK Challenge Of Rolling Out 50m Smart Meters

Posted: 29 Nov 2010 05:40 AM PST

Centrica Uses Panasonic Toughbook To Assist With 2m Installations By 2012

UK. 29 NOVEMBER 2010: Rugged PCs will be the mobile device of choice for power companies as their field engineers' look to rollout 50 million smart meters across the UK over the next two decades. That's the verdict of IDC, leading IT analyst company, in its latest white paper on "The Role of Rugged PCs in Successful Rollouts of Smart Metering Systems".

In July this year, the UK Government's Energy Department issued a prospectus for the nationwide implementation of a smart metering program. The department is expected to make a final decision on the action plan by the end of this year.

According to the Energy and Climate Change Department, the rollout will be a major effort, involving visits to more than 27 million homes and the installation of around 50 million smart meters over the next two decades. Multi-billion pound benefits across the domestic and smaller non-domestic sectors are projected, coming in large part from reductions in energy consumption and cost savings in industry processes.

Centrica PLC, one of the largest energy providers in Europe, has already equipped its UK smart energy experts with the Panasonic Toughbook CF-H1 Field, a rugged tablet with high visibility LCD screen, dust and water endurance and water resistance. With 100,000 smart meters already installed in the UK, Centrica is on track for 2m installations by the end of 2012.

Before choosing Panasonic Toughbook, Centrica evaluated around 20 different types of mobile device, studying the battery life and screen size and clarity of the device as well as ease of use with a single hand and whilst wearing gloves. However, most crucial was the ability for the device to run a standard Windows 32-bit environment for its native built applications.

"Application flexibility requires real computers," explained IDC analyst Giorgio Nebuloni. "The need for a rich operating system, typically Windows 32-bit, and the ability to support intensive workloads such as encryption and cartography means that the PDA falls short when it comes to delivering a full experience."

IDC said the key takeaways for utility companies when buying mobile computing devices were:

- Ruggedness is a given. All companies interviewed claimed to be happy with the choice of a rugged device. Even more than that, they took the rugged form factor for granted, arguing that without it everyday operations would become virtually impossible due to failure rates.
- Connectivity. There is a full range of activities performed by field engineers that require access to the Internet or intranet, GPS, 3G, and WiFi connectivity. A connected device allows engineers to work remotely and strongly reduces the travel distances, making savings in that area too.
- Application flexibility requires real computers. All users reported the need for rich OS, typically Windows 32-bit, and the ability to support compute-intensive workloads, such as encryption and cartography. PDAs often fall short when it comes to delivering a full experience.
- The whole package is important. More than once, the product deployed was accepted and used more quickly because the device manufacturer was able to offer what seemingly were small improvements to offer a total solution for the field engineers.
- An act of balance. All utilities are looking for the perfect balance between devices with a large enough screen, enough computing punch, and portability, all without sacrificing durability. So far, compromises have had to be made in one direction or the other, but, as technology evolves, new form factors combining touch, portability, and power will help make the choice easier.

Learn Basics Of Robotics With Simple Line Follower Robot

Posted: 29 Nov 2010 04:54 AM PST

thanks a lot to all of you for the interest...so here i my first post.

since robotic has been a filed which is very vast i would like to start with a very simple example...
line follower robot.

for this we need.
1) micro controller -> since there are many new engineer out here i am going to select atmel atmega series micro controller
2) ir sensor or sonar sensor which ever is easily available.
3)interfacing between sensor and uC.
4) avr studio to write the code
5) motor and its interfacing with the uC.
6) motor driving IC
7) interfacing on motor IC with uC
8) deploying the code
9)trouble shooting

in the upcoming post i will try to explain each of the topic in details...
and if you think i have missed something kindly update me...

thanks and regards

Intex IN8810 V.Show Mobile With Built In Projector Reviews And Price In India

Posted: 29 Nov 2010 04:49 AM PST

Intex is going very innovative with its range of mobile phones. The company has recently launched Intex V.Show IN 8810 - the phone with inbuilt projector! That means you can put your photos and videos for display on wall or a big screen.

The IN8810 V.Show is a touch-screen phone that expands its screen upto 36" via projector mode. The company claims that there is 3 hours of project time on battery, which I think is more than what anyone would expect. Imagine projecting a full movie on big screen using this phone! The life of the inbuilt projector lamp is said to be 20,000 hours.

The phone also has quick-charge battery, 64MB internal memory that can be extended to 16 GB via MicroSD card.

In addition, this phone has dual GSM network support which you will find in any of the latest mobile phones available in India. However, it would be interesting to know how the dual-SIM phones sales will be once the Mobile Number Portability (MNP) is fully launched all over India.

The price of this phone is not correctly known. Various websites are pricing this phone between INR. 12000 - 16000.

The Humble Cycle Rickshaw

Posted: 29 Nov 2010 01:49 AM PST

Hi everyone,
We've seen rickshaw pullers (though there are only a few left) straining very hard to carry 2-3 people for a ride.. Can something be thought about the chain and the pedal arrangement. . Couldn't there be some other mechanisms with which cheap but effective cycle rickshaws be made.!
Comments invited))

Another silly question regarding the transmissability of power.

Posted: 29 Nov 2010 01:06 AM PST

I am back with another silly doubt of mine!:hehehe:
Suppose I have a power plant of my own. I can produce 20MW of power. But the substation near my plant has users who only consume a total of 3MW of power. Before I start up my plant, I studied the sub-station.Its a 33/11kV substation. I saw that it is initially consuming power from another substation with is a 132/33kV substation. A thought struck my mind. If I do supply the 33/11kV substation with all my power, can I be able to connect and transfer my power to the 132/33kV substation? That is, if I give 20MW to the 33/11kV substation, will it export the excess power back to the 132/33kV grid? I can't connect the power plant directly to the 132/33kV substation as it is 40km away. Laying down 40km of transmission line will make my investors really unhappy.


I require the answer for this question really fast. Please let me know about it. Thank you.
Again, sorry for taking time.
