The Experts Voiceby,Mr.Ananth Saradhi

I have been asked to write an article motivating students to develop interest in technical disciplines andproject work.

When I started to write, I remembered vividly, searching or an organization to do my nal year projectwork. In the late 90s, there were very ew organizations where an undergraduate student could work on pro-

jects and develop technical skills.

I have learnt many technical skills the hard way, most o them during my masters at USF. I worked on pro-jects involving dierent disciplines and such work enhanced my resume. I owe all my skills to the projectsdone at USF!

However, times have changed and so has the job market. Learnability and independent thought are valu-able skills. Tey are acquired only when a student does two things: develops interest in learning new knowl-edge and applies this learning by way o independent thinking.

Project work is the best way to learn new things and apply independent thought. Project work in engi-neering is possible only when interest in the technical disciplines is developed and enhanced by constantdiscussion and ollow-up reading, which is already being done in an inormal setting. We need to keep at itand the results will ollow.

Te most obvious advantage o project work: You understand what is taught and learnt in classrooms and

laboratories very easily. A successul project can be converted into a publication. Project work shows youwhat works and what doesnt and this knowledge enhances the quality o publications produced. It enrichesthe student learning experience.

Publications and project work do the talking or a candidate at any job interview, even management posi-tions! Tey tell the interviewer something (good!) about you. As one o my riends pointed out, engineeringmanagers need to be technically competent because they manage engineers! echnical competence is alwaysan asset to a manager. Steve Jobs and Bill Gates are a case in point.

Te concept o undertaking projects to enhance skills and thereby resume has already taken ight in ourdepartment and initial results are promising, to say the least. I hope this tradition grows to become secondnature in all o us.

Phoenix /:.nIks/ noun [C usually singular]: In ancient stories, an imaginary bird which set re toitsel every 500 years and was born again, rising rom its ashes.

During the reshers meet that happened in September this year, the juniors were asked i they knewwhat Phoenix stood or and none o them replied. Well, Phoenix, the ECE and EEE association actually is shortor Perpetual Hankerers o Electronics. Quite a name youd think. Te name aptly suited the association thisyear, more so because it was dormant or most part o the last two semesters and this time around it rose romits ashes, like the bright orange bird, uttering its widespread wings and ying out with grand elegance.

Te whole association is proud o the act that we could successully hold two very interesting eventsand attract immense and very enthusiastic participation rom students o all the three years. We have a very

innovative and interested bunch o people at the helm, right rom the president to the core members to theeditorial board, whose constant eorts cannot be played down in any way. New and innovative ideas crop upin every meeting, be it regarding the events or the t-shirt or any random discussion to make the associationmore active.

We had the rst ever robotics event during Shangri La, a line ollower event, race the Line which sawa good number o participants register. Interestingly enough, a rst year team won the event by a comortablemargin and second place was taken by a third yearite. Te place where the event happened depicted a scene ohealthy and much needed technical competition or this nascent campus, where the students are still in a stateo brain-storm. Lots o people also came down to just have a look at the event, which was a very encouraging

sign both or the organizers and the participants.

E-trade, another standard event rom the Phoenix association, was held during Shangri La. Tis eventreceived excellent participation as well; approximately 150 students took part and 8 teams made it to the nalround. Te rst round was a written one where the students were tested on the basics o general electronicsand electricity concepts. In the nal round, the teams were given a variety o questions that tested both theirknowledge and aptitude in the subject. Again, two teams rom the rst year were in the top three. Kudos to allthe winners!

Te t-shirt which is soon to be launched is assuredly very impressive and will denitely grab youreyeballs. Te association this year has already held ew enormously successul events and would continue torelentlessly aim or better and bigger events and get wider crowds and more energetic participation rom notonly the ECE EEE students, but also rom the other disciplines. Te newsletter will be coming out every oncein a short while to keep you engaged, inormed and also, hopeully, entertained regarding all the happenings inthe world o electronics both inside and outside this campus. Hope you have a good read!

The PHoEniX election Freshening Freshers Day

It took the contestants three weeks o healthy, albeit

vigorous campaigning to be prepared to ace the judg-ment day. In what is by some distance B.P.H.Cs big-gest associations most prominent democratic exercise,ECE/EEE Association with 705 eligible members, wereto elect their Oce bearers in second week o October.

Te was held on12th October 2011, as scheduled. Overall, turnout inthe elections was projected at 57 percent o registered

voters, about 7 percentage points higher than that o

the last year.

Amidst huge speculations the ocial results werereleased on eve o 15th October 2011. Te resultsdeclared the names o the Elected Oce bearers andthe selected Core members, which included Nucleusmembers, Event Coordinators and Te EditorialBoard. Te newly elected Oce bearers had big shoesto ll.

Te list o Te PHoEnix Oce bearers or theacademic year was declared as ollows:

It was the 16th o September, the day when

one o the major on-campus groups organized thereshers meet or the new batch o 2011. Just like oth-er E.C.E/E.E.E students o the batch 2011, I was superexcited about the Phoenix reshers meet. It was sup-posed to be our day to be entertained & to entertain.Te reshers meet began with an inspiring introduc-tory speech by Harish, the then President o the asso-ciation. It was ollowed by the release o the splendidmagazine o the group LIVEWIRE. Te hard workput in by every member was completely visible thro-

vugh the colours o the magvazine.

Te aculty members, Madhuri madam andMoorthy sir, were also present there to boost our en-ergy to higher levels! But the un was yet to come!!!Afer all the ormal intros, we had some really coolstu! Ten was the time or us to show our skills! oshow that we were no less than the seniors! Te quizorganized, had an enthusiastic participation o thereshers.

But what is reshers day without the declara-tion o the Prince and the Princess!!! Hence was theMr & Ms resher event organized. Te newcom-ers were a little hesitant but in the end there was adecent participation. Every participant had to aunttheir talent and was then reerred into the next rounddepending on how much he or she could convincethe jury, which consisted o our seniors. Afer, threerounds o entertaining (and yes it was super enter-taining!!!) selection procedures, we nally got our Mr

& Ms Fresher, Mayank Goel and Priyanka. I thor-oughly enjoyed each and every moment o this day.Te seniors had lef no stone unturned to make thisday special or us. But every good thing comes to anend and so did this event.

With lots o special memories

Dennis Ritchie:The Shoulders Steve Jobs Stood On

Source: Googleimages

by, Sumanth Nepalli.

Te tributes to Dennis Ritchie wont matchthe river o praise that spilled out over the web a-ter the death o Steve Jobs. But they ought to. Denniswas ound dead on October 12th 2011, one week aferthe demise o Steve Jobs. Tough the response romhardcore techies was immense, the collective eulogyrom the web at large doesnt quite do justice to Ritch-ies sweeping inuence on the modern world. DennisRitchie is the ather o the C programming language,

and with ellow Bell Labs researcher Ken Tompson,he used C to build UNIX, the operating system thatso much o the world is built on including the Ap-ple empire overseen by Steve Jobs.Ritchie was born on September 9, 1941, in Bronx-

vile, New York. Ritchie grew up in New Jersey, andafer a childhood in which he did very well academi-cally, he went on to attend Harvard University. Terehe studied science and graduated with a bachelorsdegree in physics. While he was still going to school,Ritchie happened to go to a lecture about how Har-

vards computer system, a Univac I, worked. He wasascinated by what he heard and wanted to nd outmore. Outside o his Harvard studies, Ritchie beganto explore computers more thoroughly, and was espe-cially interested in how they were programmed.While still at Harvard, Ritchie got a job working atthe Massachusetts Institute o echnology (MI).He worked at MI or many years helping develop,alongside other scientists, more advanced computersystems and sofware.

Ritchie began working with Kenneth Tompson,who had joined Bell Labs in 1966. Both men hadbeen watching how the minicomputer was becomingmore and more popular in the early 1970s. What wasneeded, they thought, was a simpler and more eas-able interaction between various computers. It tookthem months to come up with a solution, but whenthey were nished they had written the Unix operat-ing systemUNIX was written in machine language, which had a

small vocabulary and did not deal well with multiplecomputers and their memories. So Ritchie combinedsome aspects o the older systems with aspects o thenew one, and came up with the C programminglanguage.

In the early twenty-rst century, C is still thedominant language o computer programming. It wassuch a simple, concise language that almost every sin-gle computer maker at the time switched to it.By 1973 Ritchie and Tompson had re-written theUnix operating system, using C instead o machinelanguage, and had done massive testing on it. It was sosimple to use that programmers all over were switch-ing to smaller machines to do their programming,

giving up the larger computers they thought theywould never want to leave. Bell Labs became Lucentechnologies Inc., and began to sell Unix to develop-ers, creating a whole new division or the company.Ritchie has credited his success in part to the act thathe did not have a computer background and thereorehad an open mind to possibilities that others mightnot have thought existed.Computer historian Paul E. Ceruzzi quoted:

Ritchie was under the radar. His name was not ahousehold name at all, but . . . if you had a microscope

and could look in a computer, youd see his work

everywhere inside.Te Fedora 16 Linux distribution, which was releasedabout a month afer he died, was dedicated in hismemory.

Do It Yourself - Automated Night Lampby, Sai Praveen

Aim: o make an automated night lamp that glows whenever light is turned OFF.

Apparatus: A npn ransistor (BC548), Light Dependent Resistor, Potentiometer (100K), LED (RED),2 Resistors (470Ohms and 10KOhms), a battery (+9V)

Procedure: Connect the components as shown in circuit on a bread board or a solder it on a PCB.Working: Lets not go deep into the working o a transistor. In the simplest terms a npn transistor acts like

a (water/gas) valve - a small current into the base is used to control how much o a muchbigger current ows between the other two pins, just like the amount o water owing out romthe tap depends on opening o the tap. Here the valve o the tap can be compared to the base,the aperture o the tap can be compared to collector and the water owing out is the current.Coming to LDR, the resistance decreases with increase in light intensity. Tus in darkness it actsas nearly insulator (resistance ~ 2MOhms)

In the given circuit, the LDR is connected in

series with pot orming a voltage divider and thus giv-ing a voltage at point X inverse proportional to lightintensity. In darkness because o its high resistance theLDR doesnt allow current through it, so the wholecurrent goes through the base o the transistor turn-ing it on. Te amount o current can be controlled bychanging the potentiometer and tuning it according-ly. Te LED is connected to the emitter pin o BC548

transistor, i.e., output is connected to the LED. unethe pot such that the LED is switched ON only whenthe lights are turned o. Te Pic shows the circuit ona bread board and PCB comparing the size with a 1Rupee Coin.
