Foxhunt, an event by Alacrity, was a test of the participants’ antenna-making and treasure hunting skills. It was a team event which consisted of three rounds spanning all four days of TechTatva. Round one was a written round, designed to test the contestants’ knowledge of basic electronics and general aptitude.

Eight teams had previously cleared the written test that was assembled in the Basic Mechanical Workshop. For Round two, they began building their antennae after the event heads’ demonstration of how to build its basic structure. Initially, the participants found it rather difficult, but the organisers and event heads helped all the teams out and answered their queries. “The teams should make sure they get the lengths of the reflector and director correct or else the phase will shift and the antennae won’t detect any signals”, said Dishali Jain, the Event Head, when asked about what the most important aspect of the antenna was. Held in the Digital Electronics laboratory, the second phase of Round two,  had the contestants placing all the components of their antennae together such as the coaxial cable, voltage divider, potentiometer, and speakers.

On the day of the finals, the teams set up to find their treasures once their antennae had been tuned. The treasure hunting process involved listening for signals through the speakers which were being broadcasted every five minutes. Using this, they triangulated the position of the treasure.

The event gave the participants a better understanding of their subjects through more innovative methods. Ganesh, a second year ECE student said, “This event was quite interesting because I got to see the real-life applications of certain concepts I had learned about in class.”

MazerLazer, organised by Alacrity, was a perfect blend of optics and mathematics. This event saw ample participation and enthusiasm that increased with each day.

Initially, off to a slow start, the event slowly picked up the pace. The first round was a pen and paper round which tested the participants’ general knowledge and aptitude. The organisers did a good job narrowing down the teams to twelve per team for the second round which had two parts to it. The first part was a questionnaire, the answers of which held the directions of the second part. The second half of the round kept the contestants engaged throughout, having them arrange prisms, mirrors, and glass slabs. For the laser beam to reach its final destination from the starting point, the directions from the first half were necessary, bringing together all aspects of the round.

The final and most exciting round was once again divided into two. The first part, a knockout round, required the teams to construct a given path in a water tank. They were each provided with lasers and optical instruments. Pitted two at a time, only three teams proceeded to the second part of the finals. This round was the most complex as it tested the participants’ creativity as well as their optical knowledge. After five minutes of brainstorming, each team was given twenty minutes to implement their idea in a water tank again. While some tried to star their way to the top, others sought beauty in symmetry.

The organisers and the Event Heads were quite impressed by the quality of the teams. “The participation was good and it matched our expectations”, said Ujjwal, one of the Event Heads. This event, a yearly feature of TechTatva, was much better than its previous editions.

Spotlight was an online event conducted by Alacrity during TechTatva’18. This online event consisted of logic puzzles and general knowledge in the form of questions related to a broad spectrum of topics such as science, movies, history, and even TV shows. The quiz had 25 questions that covered a variety of topics. One of the tools that helped competitors in this event was Google. Since it was an online event which was being conducted 24/7, participants had the luxury of googling the facts they needed to answer the questions. Each of these twenty-five questions, when answer correctly, revealed a part of a picture. The picture had twenty-five parts, in a 5X5 grid, which was the final puzzle in the event. On finding a connection with the picture and solving this final puzzle, the quiz was solved. With two winners, the event proved to be a fun trivia quiz with logical and analytical skills of the students being put to the test.

Taught and tested on the art of metal detection, participants had their mettle tested in this two-day event, Electrobuzz, which was based on a very popular electronic application.

Kicking-off with a written test on general aptitude and reasoning, and also a couple of pop culture questions, the first round was held in NLH-305 on the first day of TechTatva’18. Participants were completely engrossed in the paper’s riveting questions and the negative marking scheme. Sasnika, an organiser, said, “The turnout was out good, but not more than what we expected.” The select few participants deemed worthy of metal detection, were taught a basic lesson on electronics the next day.

After the introductory course, the participants applied their knowledge at the Digital Electronics Lab in AB-5. Using styrofoam, they made a solenoid by utilizing the simple principle of electromagnetic induction to make a functioning metal detector. From the organisers to the participants, everyone was spirited and on their toes throughout.

After their detectors were assembled, the final round saw the participants test out their feats of engineering in a race against time. One participant from every team was first brought to a dark room where they were made to find small hidden pieces. They would later use the metal detectors they had built, to distinguish between metals and non-metals among the pieces.

The round was especially fun for the organisers, as they were aware of the positions of the pieces while watching the participants trying to find them. The event turned out to be a successful learning experience for everyone involved and had a certain electricity to it, that is brought by the category every year.
