radiation in India is about 5.2 to 6.5 kWhper square meter per day. There is ampleland and roofs are available in India for

solar park. State Government and centerGovernment is taking initiative steps totake advantage of solar energy. . As solar

panels increase in efficiency, more andmore applications will begin to use themas either a primary power source or as abackup power source. For applicationswhere the ambient light is continually

changing, the Maximum Power SolarConverter can be a very effective tool inincreasing the total power delivered bythe solar panel. Implementation of suchmaximum power solar converter is dis-cussed here. Solar panels are an array of

solar cells. Cells are connected in series-parallel combinations of various archi-tectures to scale up voltage and currentrequirements. Solar panel comes in dif-

ferent shape and size. To get the solarpanel to operate at its maximum powerpoint, there are a few items needed. First,

in order to know the output power of thesolar panel, both the current and voltageof the solar panel have to be monitored.This will be accomplished by a high sidecurrent monitor and simple resistor di-vider on the solar panels output voltage.

There also needs to be a way to controlthe output power of the solar panel. Thisis done by manipulating the panels out-

put current. And lastly, a software algo-rithm is needed to know which way tomanipulate the current (e.g., whether the

Minor projects related to Implementation of Green

technologies. - Dr. C. H. Vithalani (HOD Electro. & Comm. Dept.)current out of the solar panel should beincreased or decreased).A solar panel

generates maximum voltage in two cases:[1] When there is full sunlight on it and[2] When there is no load connectedacross it. Output voltage of solar paneldecreases as sunlight reduces or currentis drawn out of it to drive load or tocharge battery. We will get maximumefficiency of solar panel, if we operate itat knee point of I-V characteristics. Prob-lem is that knee point is not fix, knee

point changes as intensity of sunlightchanges. Knee point also changes whenthere is temperature variation on solar

panel. Thus, we require some dynamiccircuit which monitors voltage and cur-rent continuously to find out knee pointand operates solar panel at knee point.We can implement circuit with help of

PIC16F690 microcontroller to monitorknee point and take power from solar

panel according to knee point. BasicCkt Diagram & B/D with PIC16F690:

We know that we are exploiting earthsresources to feed our daily needs and to

feed hungry devices like Automobiles, Airconditioners, Lighting, Industry plants,Computers etc. We have damaged envi-ronment to satisfy our needs and due tothat temperature rise, glaciers melted,

fertile land is becoming parched, andwind direction changed and schedule of

seasons becomes irregular. We alwayscomplain about ourselves whenever wemeet at some conference, meetings re-lated to Green technologies though at themeeting place itself all these resourcesare being used. We must admit that wecannot live without all these resources sowe have to find out some alternative waysto solve the problems. In this article, im-

plementation of Green Technologies us-ing minor projects is discussed. Final

year and pre-final year students are ad-vised to think in this directionIncreasing efficiency of solar panel

Smart shoes vibrate you in the right directionusing Google Maps - Aishwarya Jayadas (EC 3rd)

Le-chal shoes and insoles work with Google Maps on yourphone to buzz your feet when it's time to turn.Indian wearable tech startup Ducere Tech has created smart shoes called Le-chal that can give the wearerdirections without needing to look at a smartphone. Le-chal means "take me there" in Hindi.

Krispian Lawrence and Anirudh Sharma developed the device primarily as an improvement to thewalking and navigation aids currently available to the blind.

When you're out running, walk- ing, or biking, it's inconvenientand potentially hazardous to keep your eyes glued to the map

on your phone. Imagine if your shoes told you which way to gowithout you ever having to take your eyes off the road or side-

walk. That's the idea behind the Le-chal smart shoes and insoles

from Ducere Technologies.The shoes sync over Blue- tooth to an app that pulls yourpath from Google Maps. The shoes buzz to tell you which direc-

tion to turn. A buzzing right shoe means to hang a right. A buzzing left shoe means to go the other way.The shoes were originally designed to help people with visual impairments navigate more effectively, but

the company's founders soon realized there could be a much wider market.Potential uses for the Lechal go beyond just getting somewhere. They can also be used to send prox-

imity alerts to phones, notifying tourists of interesting landmarks nearby. The footwear will alert youshould you accidentally try to leave your phone behind so you don't get stuck out in the middle of nowhere.

The shoes also aspire to work as a wearable fitness monitor, tracking steps and calories burned.

Today, synchronous processors consist of hundreds of millions of tran-sistors and reach clock rates up to several GHz. the high clock ratesimply that several millions transistors switch several billion times a

second, means up to 40% of power consumption is spent in the clock generation, the drivers. the asynchro-nous microprocessor. Asynchronous are different from synchronous processor is the designing technique of

synchronizing the sequential elements among each other .communication between several parts of theprocessor can be self-timed and since the asynchronous microprocessor do not have central clock, there is

no need to adjust operational speed of each part & each part can operate at its maximum speed withoutaffecting the other components. For example ALU can execute an add operation in half time of a multipli-

cation. In synchronous processor ,the clock cycle has to be at least as long as slowest operation even ii thisoperation is rather rare . In synchronous processors the system is slowed down only if this rare operation

occurs otherwise it operates faster.

FYI, asynchronous processor have some specific advantages like up to four times higher energy efficiencythan synchronous elements ,which makes them useful in niche areas like smartcards where low power areimportant .in future may be asynchronous processor may also benefit from techniques developed for asyn-

chronous processors ,like lowering supply voltage & thats easy to implement in asynchronous design.

Whatisadad?

A dad is someone who

wants to catch you before you grow up,brushes you off,and let you try again.

A dad is someone whowants to keep you from making mistakesbut instead lets you find your own way,even through his heart breaks in silence

when you get hurt.

A dad is someone who

holds you when you cry,scolds you when you breaks rules,shines with pride when you succeed

and has faith in you even when you fail

Connectivity betweenworlds two largest and

unsolved question..!!

-RAMANUJ BHAVESH (EC 5thA)

There are two questions in world which are notsolved till now first one is the birth of galaxy andsecond is the birth of human being. In India, in the

sight of religion soul has a great importance ac-

cording to religion The soul is a one form of

god. Which is not seen, formless, and colorless

from which it came and gone no one knows butsoul is transfer from one body to another body. Re-

born and before born are scientifically proved.

In present time scientist are capable to

make blood using stem cell. But most important

thing is soul ,without soul our body is meaningless.

Soul is working as a battery. As electronic item does not work without battery as same our body will not work withoutsoul. What is soul? Till now scientist could not found. In sight of religion the soul is one type of energy which is created

by god. If we found the secret of soul (Energy), we found the secret of human being.Other important question is the birth of galaxy .Galaxy is group of stars , planets , satellite and other space ele-

ments which are internally connected by gravitational force. According to law of thermodynamics energy is neither be

create or nor be destroy but it can transfer from one form to another form . At present scientists found HIGS BOSONwhich is the smallest particle, it is also called god particle.God particle are responsible for the birth of earth. From Einstein equation E= mc^2 HIGS BOSON is the

smallest particle in mass. We can take m= HIGS BOSON. That means energy is related to this particle and we discussed

above that soul is one type of energy that is colorless , formless , and neither created nor destroy. Energy and soul both

have same characteristic. According to the scientists god particle is responsible for the birth of earth and accordinglythey are also responsible for the birth of galaxy because earth is one part of galaxy.

If we find the solution of these two questions, first we consider science and religion together because scienceand religion are two sides of coin.

According to religion In every micro particle god are present and according to the science god particle

are responsible for the birth of earth.

Google Glass

Google Glass is a type of wearable

technology with an optical head-

mounted display (OHMD). It was de-

veloped by Googlewith the mission of

producing a mass-market ubiquitous

computer.Google Glass displays infor-

mation in a smartphone-like hands-freeformat. Wearers communicate with the

Internet via natural language voice

commands. Google started selling

Google Glass in the US on April 15,

2014 for a limited period for

$1500, before it became available to

the public on May 15, 2014 for the

same price. Before that users were re-

quired to receive invitations before

they could try Google Glass. Google

provides four prescription frame

choices for $225.00 U.S and free with

the purchase of any new Glass unit.

It is necessary to remove a small

screw in order to move the Google

Glass from one frame to another.

Google entered in a partnership with

t h e I t a l i a n e y e w e a r c o m -

pany Luxottica, owners of the Ray-

Ban, Oakley, and other brands, tooffer additional frame designs.

Features :

Loc Le Meur controls Google Glass

using the touchpad built into the side

of the device.

Touchpad: A touchpad is located on

the side of Google Glass, allowing

users to control the device by swiping

through a timeline-like interface dis-

played on the screen. Sliding back-

ward shows current events, such as

weather, and sliding forward shows

past events, such as phone calls, pho-

tos, circle updates,etc.

Camera: Google Glass has the abil-

ity to take photos and record 720p

HD video.

Display: The Explorer version of

Google Glass uses a Liquid Crystal

on Silicon (LCoS), field-sequential

color, LED illuminated display. The

display's LED illumination is first P-

polarized and then shines through

the in-coupling polarizing beam

splitter (PBS) to the LCoS panel. The

panel reflects the light and alters it

to S-polarization at active pixel sites.

The in-coupling PBS then reflects the

S-polarized areas of light at 45

through the out-coupling beam split-

ter to a collimating reflector at the

other end. Finally, the out-coupling

beam splitter (which is a partially

reflecting mirror, not a polarizing

beam splitter) reflects the collimated

light another 45 and into the

wearer's eye.
