Forget nanotech, think claytronics

Image
Videoconferencing is like visiting someone in prison. You talk through a glass wall, but you can't deal with each other in a meaningful way. With claytronics you could fax over an exact copy of your body, which will sit in that conference room thousands of miles away, mimicking your moves in real time and speaking with your voice. Clayronics experts are designing a kind of programmable clay that can morph into a working 3-D replica of any person or object, based on information transmitted from anywhere in the world. The clay would be made out of millions of tiny microprocessors called catoms (for "claytronic atoms"), each less than a millimeter wide. The catoms would bond electro-statically and be molded into different shapes when instructed by software. Think of claytronics as a more workable version of nanotechnology, which in its most advanced form promises to do the same thing but requires billions of self-assembling robots. Proc

Being in Love

Image
Being in love is a great experience. Nothing compares to the time spent with your loved ones and when he/she is not around, you still want to tell him/her about everything you even think about.,..You can choose to express your love in many ways. You could choose perfumed letter paper in baby pink with tiny hearts sprinkled all over it, or you can do your own thing. Whatever it may be, select appropriate stationery. Decide whether you prefer torn-out notebook paper or perfumed sheets crawling with flowers. Consider other creative means of expressing your devotion: Scrawl confessions on a mirror, fan or a piece of cloth. Fire off a quick succession of postcards. Draw things like hearts, flowers, etc., on the letter paper. For heaven's sake, don't draw peace signs, yin, yang, etc. If your love is somewhere far away, it is tough. Any long-distance relationship can be rough, so write frequently. Take time during lunch breaks at work and write a few sincere lines a day. After three

Blind People Can Read SMS

Image
Nokia has introduced an interesting piece of software, called Nokia Braille Reader. The new application allows blind people to read a discreet SMS using phone vibration. The Nokia Braille Reader application gives SMS for the blind and visually impaired and captures received SMS messages and brings them to the foreground for reading using Braille and tactile feedback. Developed at Nokia Beta Labs, the application has been developed in a joint project between Nokia, Tampere University and the Finnish Federation of the Visually Impaired. The Nokia Braille Reader application is an application developed specially for blind people using Nokia mobile phones. The application uses Braille and also a tactile feedback to enable blind people to read SMS messages. Each text message is fed into the application and the characters are converted into braille. Then each character is read out to the user using the vibrating facility of the phone. As braille is a series of raised dots each character can

getting started with java

1. Navigate to www.java.sun.com and download the Java JDK or Java SE, not JRE (Java Runtime Environment). Once its downloaded, install it. Then restart the computer. ( restart is not necessary ) 2. Open the notepad and write the following code: public class HelloMahajan{ public static void main(String[] args){ System.out.println("Hello Mahajan!"); } } 3. Save this code as HelloMahajan.java. In Windows, make sure you choose the "all files" option from the file type drop down list box, otherwise it will be saved as a text file and not a .java file. 4. Click start > run and type command or cmd 5. From the command prompt, drill down to the folder where you saved the HelloMahajan.java file. (type "cd " you can use tab for auto completion) 6. Type the following: javac HelloMahajan.java and press Enter. You should see that after thinking for a while the computer returns to the command prompt. 7. Type "java HelloMahajan" (no quotes) and see wha

'Self-healing' Polymer

'Self-healing' Polymer May Facilitate Recycling Of Hard-to-dispose Plastic Researchers in The Netherlands are reporting development of a new plastic with potential for use in the first easy-to-recycle computer circuit boards, electrical insulation, and other electronics products that now wind up on society's growing heaps of electronic waste. Antonius Broekhuis and colleagues note in the new study that so-called thermoset plastics are widely used in consumer electronics due to their hardness and heat resistance. These plastics, however, contain additives and reinforcement materials that make them almost impossible to recycle. So-called thermoplastics, in contrast, are softer and can be remelted easily. As a result, thermoset plastics often end up in landfills or incinerators, where they can contribute to pollution. Scientists have long-sought a simple, inexpensive process to make these plastics recyclable, but they have been largely unsuccessful until now. Broekhuis and co

making a Lan wire

Image
Image one is crimping tool; second and third is RJ-45 connector and fourth is peeled lan cable... Cables are generally of two categories,, 1)CAT-5 2)CAT-6 former belong to the category of UTP( unshielded twisted pair ) and later to STP also the EIA/TIA(electronic industry alliance or association and telecom industry alliance) has maintained two standards 568-A and 568-B.. When u peel off the jacket of the lan cable you will get eight types of wires in a pair of four ..these are: 1)white with orange stripes(call it white of orange or W/O) 2)Orange 3)white of green 4)blue 5)white of blue 6)green 7)white of brown 8) brown also at both the ends of lan cable we have two connectors .. These are RJ-45 connectors... always hold connectors with knob side downward..And when we place the wires in the above mentioned fashion in the RJ-45 connector it is 568-B standard.. EIA/TIA has defined three categories of cables... 1)straight cables 2

Brain Machine Interface-

THE IDEA It all came to mind from the sci-fi movie “The Matrix”, those rebels putting on the computer cords at the back of the neck—probably between the occipital bone at the base of the skull, and the first neck vertebra. The bioport (that’s what the technology was called in movie) was a way of giving the Matrix computers full access to the information channels of the brain. The rebels use the bioport to load new skills into their colleagues' brains—writing directly into permanent memory. Making it possible for rebels to learn things in seconds like flying a helicopter. Think if this could materialize into reality. No need to go to colleges just download the the whole semester books into your brain, you could read your favorite novels in seconds, learn “Kung-Fu”, possibilities could be endless. FROM VIRTUOSITY TO REALITY Moving to reality, many researches are actually going on to explore the possibility of the man and machine merger. Scientists have already got some breakthrough

Cable Television

Cable television is a system of providing television to consumers via radio frequency signals transmitted to televisions through fixed optical fibers or coaxial cables . Traditionally television broadcasting (via radio waves) uses over-the-air method in which a television antenna is required. Earlier there was no technology to record programs. After the invention of camera, they recorded the program and transmitted it via an electric current to a TV set, where the antenna converted the electrical pulses back into the original images and sound. These signals were actually transmitted over radio frequencies, which travel in straight lines. So, if TV wasn’t in the “line of sight” of the source, the signal was blocked, and TV screen would be blank. As a result, the only people who had TV’s in those days (back in the 1950s), were those who lived on higher ground, or were close to the source of the program. But People who lived in the valleys of Pennsylvania (U.S) came up with a creative

microprocessor 80286, 80386 , 80486, pentium

80286 microprocessor: Basically this microprocessor is an advanced version of 8086. So before starting with 80286 we must know something about 8086. Intel 8086 is a 16 bit microprocessor intended to be used as a CPU in a microcomputer. The term 16 bit means that its arithmetic logic unit, its internal registers, its instructions are designed to work with 16 bit binary words. It has a 20 bit address bus and 16 bit data bus. So this means that it can address any one of the 1048576 memory locations and it can read data from or write data to the memory and ports either 16 bit or 8 bit at a time. Here the word is stored in two consecutive memory locations. Also one thing to note here is that if the first byte of the word is stored at even address, the 8086 can read the entire word in one operation. Alternatively if the first byte of the word is at odd address, then the 8086 will read the first byte in one operation and the second byte in the second operation. 8088 is just similar to 8086 bu
