Will Ferrell at his hysterical, satirical best!

From the guys who brought you Talladega Nights and Anchorman comes a hysterical comedy starring Will Ferrell and John C. Reilly about two spoiled guys who become competitive step brothers after their single parents get married.

This family ain’t big enough for both of them!

Watch this Trailer, a really funny movie.Funny trailer as well.

Do not forget to comment.

Ok so what’s new?

SEGA has released a new gameplay trailer for Empire: Total War, showcasing the next installment in the Total War RTS franchise, now set in the 18th century, a period alive with global conflict, revolutionary fervour and technological advances.

The game is under development at The Creative Assembly and for the first time ever it includes 3D naval combat situations. Empire: Total War will hit the store shelves in early March 2009.

Just play the game and and post comment here.

Camera is one of the best way to keep the memory of the old time. One can anytime take picture and just print it or keep it in computer so to keep safe his/her old memories.

Digital camera is one of the best creation done by the scientist’s.It was Steven J. Sasson who gave the final result by developing the complete Camera.In 1975 he began to start the research on the project which was given to him by his supervisor at eastman Kodak Company.He set about building the digital circuitry from scratch, using oscilloscope measurements as a reference.

In 1972 Texas Instruments introduced the first film-less electronic camera. In 1981 Sony released the Mavica ,the first electronic still camera. Mavica recorded the still images to a mini disc, that could be read by a video recorder.

The true Digital camera arrived in 1986 it was a still camera.The Image sensor could record 1.4 million pixels and produce 5 x 7 photo print.However the camera was not used by many people because very less people could afford it as it was too costly at that time.

As the time passed , the advancement in the cameras took place at a very faster pace.Also , their prices started to reduce .

Since the mid 90s , the cost of Cameras has reduced to a significant amount , so that it can be afforded by the common man. The advancement in technology has has been rapid and so is the reduction in price.Nowadays, a person can afford more than 1 camera in a family.Also the cameras have started to come in the latest Mobile Phones which has even increased it’s popularity.

Commonly known as LED(Light Emitting Diode), it is actually a p-n junction diode which is capable of emitting light. A LED operates like a regular p-n junction diode.
Diodes have to be forward biased for current transfer.

What makes a LED different from a regular diode is the semiconductor material which is used to form the p-n junction regular diodes which are generally made of semiconductor materials like Silicon or Germanium; whereas LEDs are made of materials like Gallium arsenide (GaAs) compounds and Indium(III) phosphide (InP) compounds.

In a regular diode, when current flows, energy is thrown off in form of heat. In light emitting diode, an electric current passing through the diode causes the light in the visible portion of the electromagnetic spectrum to be emitted.

LEDs can emit lights of different colors. The color of the light emitted usually depends on the semiconductor material used to fabricate the p-n junction in the diode. For example, Gallium arsenide phosphide (GaAsP) is used to make LED that emit red light and Indium gallium nitride (InGaN) for blue LED.
You would have seen several electrical devices that use LED. Using LEDs to provide visual indication in displays is very common. Some times many LEDs are packaged together to form numeric display. You even would have seen these displays on your microwaves or your washing machines for setting timers.
As LED of the higher power is developed and optics for LED evolves, LEDs are being used increasingly to replace incandescent lamps and area lighting. They are used for the UV-based water purification system as well.

I hope the article was informative. Please do comment and let me know.

Ok now here is something good for you.Ever wondered about those magic balls which have light inside..Now you can make even one for yourself.Watch this video and try it .What do you get if you put an LED inside a balloon and freeze it?It looks really cool yet it is very simple to make
