Sony makes battery less important

One of Japan's Electronic Giant company Sony has develop the world's first battery less camera. The camera literally uses mechanical power to generate electricity to power the three megapixel camera. The Twil N' Take camera requires user to turn the wheel to generate edequate electricity to for the camera. Rotation for 15 seconds is enough for the camera to take a snap of photo.

The camera reminds us of Old antique car which require spinning in order for the engine to start. Since the design looks like a pizza cutter you will only need to move the wheel as if you are cutting a pizza.

Unlike ordinary digital camera this camera does not have LCD display which user can preview the photo they have taken. But they can download photos from the camera via computer. The camera is one of the Sony product at the Eco Style Fair.

Melaka Historical City ( I would not call it a trip actually because I am from the local)

Last Saturday I went to Melaka to visit my unt. During my four days trip there we went to some of Melaka's famous historical places. On last Wednesday we have decided to make a visit to A Famosa and the Red House of Dutch. A Famosa fortress which is located at the foot of St.Paul's Hill and opposite to the Dataran Pahlawan. This fortress was built by the Portuguese which dates back to 16th century. It is one of the most visited fortress in Malaysia. It is built after the defeat of the Sultanate of Melaka which marked the end of the Sultanate. Alfonso de Albuquerque whom commanded the Portuguese fleet built the fortress to protect them from other foreign invaders. The fortress changed hand when Dutch successfully drove the Portuguese from Melaka. During the reign of Dutch they built churches and some of the administration building which are now known as the Red Houses. British had destroyed some portion of the fortress until Sir Stamford Raffles spare the small gate of the fortress from destruction.

The picture shown the small gate of the fortress which can be seen today.
This is the car used by our very first Prime Minister

Tunku Abdul Rahman during the announcement of independent. To my suprise the car is recondition and everything in the car is being replace with a new accessories and the paint and chrome are as shiny as new car. I wonder how do they get the accessories, even the radiator looks new. The brand of the car is Chevrolet. I have heard some of my relative saying that that brand is new and unreliable. Apparently they are totally wrong. But some of the accesories are a little bit too much such as cd player and modern speakers. It really affect the asthetic of the antique. Then we move on to the Red House of Dutch

While on our way to the Red House of Dutch we stop by at a excavation site. From what I read they are excavating a remain of the A Famosa Tower. The excavation is still in early process.
Next we move on to the Red House of Dutch. The Buildings there of course are in red. It is funny to see how the world have change. They use erected instead of build. and the material are very solid compared to nowadays' buildings.

Invisibility

When talking about invisibility, the first thing we can think of are Hollow man or something from the James Bond movies. Invisibility is no longer impossible as scientist have figure out a way that would one day make objects invisible. With the use of meta material, light can be bend around the object allowing light to pass through as if the object is not there. Researchers from Duke University have proven that objects can be invisible by using metamaterial as the shield. However it is not the true invisibily as it is a two dimensions cloaking and at microwave frequencies only. Visible light that human and animal perceive are at a much higher frequencies.

Hence Allan Greenleaf and his collegue from the University of Rochester have figure out a way to build a device which is able to make objects travelling through the device invisible. The device would cloak in three dimensions. It is like a electromagnetic wormhole which disconnect the object in the cylinder from the outside world electromagnetically. It would render the frequencies of light and causes it to blend into the surrounding. However the range of frequencies the device can render depends on what metamaterials have been produced. Thus the range of frequencies is limited.

It would still be useful in various application such as to neutralize the magnetic fields produced by MRI machine.

However the development of the device would still be a thing decades from now. But it has form a basis for the invisibilty cloak.

Robocon 2008



Robocon or Robot Contest is an anual event for robot competition which representitive from every country will send their own made robot to compete in the contest. Higher education institutions in every country especially will participate the contest The is organised by Asia - Pasific Broadcasting Union. Every year there will be a new theme and objective. The 2008 Robocon will be held in Pune, India. The theme for 2008 Robocon is Govinda. The game play is easy where the team that manage to held all the cheese will be considered the winner by Govinda. The team that manage to score the highest marks will be the winner for the contest.

(one of the example of robot used in Robocon)

It requires collaboration between the manual robot and the automated robots. For example in order for the automated robot to score the center cheese cube it needs the help of the manual robot to held to a certain level so that the automated robot can reach the cheese cube. However that is not the only way for the automated robot to reach the cheese cube.

As usual there will be rules and regulations for each team to comply. Robocon 2008 is set to pose more challenge for the participants

Increase Visibility of Your Website

There are many ways to increase the visibility of your website. You can either hire an advertising company to advertise your website or you can do it yourselft by using advertising program such as Google Adwords. However no matter how often you advertise you are not able to receive high traffic to your website. One of the reason is that you are not using your own domain name. Instead you use a share domain name which contain the the company name which your website is based on.

Domain name plays an important role in boosting your traffic hit. First of all the domain name gives a good impression to your visitor making your website seem well established. This will increase the confident of your visitors to your website. When you have your own domain name you can remove the undesired web advertisement which can be quite annoying especially when their present is not intended.

Registration of domain name can be made through your hosting company or through a domain registration company such as http://www.godaddy.com.
