Few Tricks for Fun… Part 1

Change the name of the command prompt into your name

In the command prompt, type “ title your_name ” (without double quotes). Then press ENTER

Result- The name in the blue bar of the command prompt will change to whatever you typed after “ title ”

Format the hard disk using a Notepad

Caution: This trick is only for educational purpose. Do not play with it.

Open the Notepad. Then type the following.

01001011000111110010010101010101010000011111100000

Then save the notepad with the .exe extension. Click the resulting .exe file. It will format your HDD

Zoom out

Press CTRL and scroll the mouse wheel. Look what happens..!

This is amazing.. try it

If your operating system is windows, just try to create a folder and name it as “ CON “. TRY IT……BUT you will NEVER BE ABLE TO DO THIS.

MS Word fun

Open MS word. Then type “ =rand(200,99) ” and press ENTER

Look what happens to your document.

Robot-like Vision

"Looking through a completed lens, you would see what the display is generating superimposed on the world outside," said Babak Parviz, a assistant professor of electrical engineering, University of Washington in Seattle. This simply means that you would possibly see anything that is projected on to the display of your contact lenses along with the natural objects that we see on the world outside..such as in science fictions. Surprising..isnt it?

Well…UW engineers have already developed a prototype of this amazing device and have already tested on rabbits for any adverse-effects. The results were truly encouraging —no adverse effects were produced by the rabbits after testing for up to 20 minutes.

The lens comprises of an electric circuit as well as red light-emitting diodes for a display. As this still a prototype the display does not light up yet. “A full-fledged display won't be available for a while, but a version that has a basic display with just a few pixels could be operational ‘fairly quickly’ ” according to Parviz.

In order to develop a safer devise with no adverse effects for eyes, engineers have used flexible organic materials to build up its electronic circuits. A method called microfabrication technique known as self-assembly has been used to set its tiny electronic components in the correct positions within the circuit. Designers of the devise say that these components will not affect the lens-wearers vision as they entirely occupy the positions outside the transparent region of the eye.

Still, researchers are continuously working on the devise in order to place further improvements to enable wireless communication, and to power up the lens using radio-frequency power and solar cells.

Brain Reader..?

A group of cognitive neuroscientists and computer scientists in the Carnegie Mellon University have successfully developed a technique to tell what other people are thinking, by observing their brain activity.

When a person thinks of some particular object, thoughts and perceptions are generated in various positions of the brain producing a particular pattern specific for that object. Different objects cause different patterns. By combining medical imaging and machine learning methods, scientists have been able to develop a novel algorithm—a set of well defined instructions to classifying them according to their corresponding objects. As a result, by analyzing those patterns, one can exactly tell what others were thinking about in a particular moment.

In addition, when this algorithm is trained from datasets obtained from a particular person, it could correctly classify unknown datasets obtained from a different person showing that there are similarities between brain activities of two different persons. "This part of the study establishes, as never before, that there is a commonality in how different people’s brains represent the same object," says Mitchell, head of the Machine Learning Department in Carnegie Mellon's School of Computer Science.

Finally researchers are hoping to develop this new technique further in order to use this as a valuable tool for studies and research in neurological disorders, such as autism.

Thanx.!

Find out your ' IP address '

You know that every network connection has its own IP address. But, do you know how to find that address? NO..? well, just follow the simple instructions below..

1) Go to Start and then go to Run

2) Type ' cmd '

3) In the opening command prompt, type ' ipconfig ' - This result will provide a little bit of details of the connection, including the IP address.

Is the above information regarding the connection insufficient? If so, just type ' ipconfig/all ' in the command prompt and it will provide you with much more information.

Try it..

Microprocessors or Microcontrollers... We are alike.... but not the same.

PIC10F is one of the world's smallest microcontrollers

• Generally microprocessors and microcontrollers differ in a number of ways, mainly in its functionality. Because microcontrollers can control a number of processes and devices independently whereas microprocessors need integration of additional peripherals with it.
  





• 
  






• This is the basic structure of a microprocessor. In order to carryout the functions, this needs to be integrated with other hardware components.

• Microprocessors are regarded as the heart of the system/computer. On order to act in such a way it needs RAM, ROM, registers, I/O devices; as said before it needs integration of other hardware. But in a microcontroller chip, it’s a whole different story. They have all the above components embedded inside; more generally it is defined as a device that includes a memory, & input / output devices and also a microprocessor, lined on a single chip. In modern microcontrollers, they contain Serial I/O, Timers, and Analogue to Digital Converters. Actually it’s more like a little computer inside a little chip.

This is a microcontroller chip; identify the microprocesser, integrated onto the microcontrolle surface.

• In simple terms a microprocessor is actually a ‘processor’. It is the ‘central processing unit’ of the computer as everyone knows. But a microcontroller is actually a ‘controller’ of a system; When we enter a certain user-defined task or a program into the microcontroller, it simply loads it into the memory, and runs/executes it.
  


• In addition, microcontrollers are cheaper
  


• Microprocessors -> General Purpose Machine
  Microcontrollers -> Embedded Systems

Microcontrollers are mainly used in embedded Systems.

So.. these are the main differences between microcontrollers and microprocessors.
