making a Lan wire

-

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)cross over
3)roll over
when we want to connect two dissimilar devices like pc and modem, pc and router etc then we use straight cables..
Straight cables use the 568-B standard at both ends...
also one tool is required called as crimping tool..

when you place the wires in the connector then compress the connector using the tool so as two make a strong contact... one thing to note after you compress the RJ-45 connector ,it can’t be changed so be careful..
Also to connect similar devices we use cross cable...
cross cable is used to connect to similar devices like pc and a pc.... according to 568-A standard the order of color is as:
1)white of green
2)green
3)white of orange
4)blue
5)white of blue
6)orange
7)white of brown
8)brown
when we place the wires in RJ-45 connector in this fashion the standard is 568-A
 cross cable has one end of 568-A and the other is that of 568-B standard thats it guys ...

AUDIO SPOTLIGHTING

Image
INTRODUCTION n   Audio spot lighting is a very recent technology that creates focused beams of sound similar to light beams coming out of a flashlight. By ‘shining’ sound to one location, specific listeners can be targeted with sound without others nearby hearing it, ie to focus sound into a coherent and highly directional beam. It uses a combination of non-linear acoustics and some fancy mathematics. But it is real and is fine to knock the socks of any conventional loud speaker. n   The Audio Spotlight & Hyper Sonic Sound Technology (developed by American Technology Corporation), uses ultrasonic energy to create extremely narrow beams of sound that behave like beams of light. Audio spotlighting exploits the property of non-linearity of air. When inaudible ultrasound pulses are fired into the air, it spontaneously converts the inaudible ultrasound into audible sound tones, hence proved that as with water, sound propagation in air is just as non-linear, and can be calculated math

INTERFACING OF EEPROM with 8051

7.1 Introduction As we know, ROM is a memory that does not lost its contents when the power is turned off. For this reason ROM is also called Non-Volatile Memory. There are different types of ROM such as PROM, EPROM, EEPROM, Flash EPROM and Mask ROM. In which PROM refers to the Kind of ROM that the user can burn information into. PROM is a user programmable memory. PROM is referred to as OTP (One time programmable). EPROM was invented to allow making changes in the contents of PROM after it is burned. In short, one can program the memory chip and erase it thousands of time. This is especially necessary during development of microcontroller based project. EEPROM is electrically erasable programmable ROM. EEPROM has several advantages over EPROM. EEPROM does not require external eraser and programming device. Flash EPROM has become a popular user programmable memory chip. The reason behind that is the eraser of entire content takes less than a second that why it is named Flash memory. Wh
