With three rounds held across four days, Foxhunt gave tech geeks the perfect platform to explore the world of communication. The event had participants compete to find a signal-pulsing transponder using antennae built by themselves. Getting started, an hour long quiz that tested contestants on mathematics, technology and general aptitude transpired in the first round. Many were impressed with the layout of the quiz, mentioning that its level of difficulty had matched their expectations, while a few felt that the test could have been more challenging.

Five teams made it to round two, which was conducted at the Digital Electronics Lab and comprised of two parts. In the first part, teams were required to implement a circuit on a breadboard using resistors, capacitors and diodes within a span of ten minutes—a duration that many felt was fleeting. With a brief demonstration given by event heads and help from organisers, successful basic structures of the Yagi Uda antenna and its receiver module were made by each team. The second part had participants design an FM Tuner and its circuit. The previously made antennae were then tuned to a certain frequency with the help of a signal generator, the FM tuner kit and its receiver module. “They’re doing exceptionally well,” said Amish Sinha, an event head, who was also impressed by the level of participation.

All five teams made it to round 3, which was held on the final day of the fest. Defined by field work and plenty of scurrying around, contestants finally got down to testing the fruits of their labour. Participants stood alert for auditory signals given out by the judge and had to use their tuned antennas to triangulate the position of the device and recover it. Poised with great participation and a joyful learning process, the event successfully educated contestants on the basics of communication and its hardware equipment.

Mazer Lazer

A keystone event of the category, Mazer Lazer had its three rounds held across the first three days of Tech Tatva. With an incredible 19-team participation, the number of contestants made for a high spirited competition and all the more excitement. Elimination entailed in the first round, with participants solving a forty-five minute long written test on aptitude, tech and pop culture.

Seven teams qualified to the second round and were briefed on making a specific module on a breadboard. Contestants were then given a glimpse of Li-Fi communication through the voicing of a music sample transferred using a laser pointer, a demonstration that left the room fascinated. After the successful completion of individual circuits, the next part of the round called for the construction of a maze of mirrors that would work on the principle of reflection.

The third round commenced the next day and comprised of all teams from the previous round. Participants were tasked with two objectives this round. The first was to recreate a given pattern using mirrors and laser pointers, while the second was to make a pattern of their own in an aqueous medium under a time constraint. The teams strongly focused on their projects, wary of the judge who toured around content on seeing brilliant patterns light up the dark room. “I loved the enthusiasm of the students in showing their creativity using the limited resources provided,” praised Shivamurthy R C, the judge for the event and an assistant professor from the Department of Mechanical & Manufacturing Engineering. Glad to not only have learned the concept, but also to have applied it in a visually descriptive way, the event was well enjoyed by all participants and was deemed a success.

Held over three days, Electrobuzz taught contestants to create their own metal detectors and forage for treasure. Starting out with brain teasers, the participants were tested on logic, aptitude and questions related to current affairs and pop culture. Many were surprised by a lack of technical questions given the event’s background and the otherwise wide range of topics. The teams worthy of wielding the metal were selected to move onto the next round.

The air surrounding the second round was abuzz with excitement as participants got to toy around with various components in the effort to build the device. While organisers paced around trying to help participants with each step, an air of cooperation nurtured in the room. Contestants tried helping each other, regardless of whether the competition held each other in regards as friend or foe. “I’m not here just for the score, I’m here to learn things“, mentioned Bhavya Manglik, a finalist at the event.

The final round had everyone ready to work their freshly built contraptions at a test field prepared. The ECE foyer in AB-5 was set up with 45 painted containers, a third of them being metallic in nature. To each container, a cardboard piece was attached. The unknown pieces were attached to cardboard pieces which were part of a puzzle. The objective of this round was for each team to pick the correct pieces according to the sound of the metal detector, and as quickly as possible, assemble a picture with the final 15 pieces covered. A shaky start ensued as the drone like buzzing seemed to dull senses, with most teams being unable to pick up all 15 pieces. However, two teams were eventually able to find all pieces, with their times missing each other by a slight margin.

Escape Plan

The Post Staff

Trapping them in a virtual maze, this online quiz had participants answer questions on all sorts of trivia to find their way out. Active from midnight on the first day till the last one, Escape Plan comprised of 31 questions across virtual paths of varying length. With progress dependent on successfully answering questions, hints were released from the second day onwards to aid those who felt helpless. The event registered over 180 participants and worked on a point-based system to rank its contenders. Solving a question would earn you one point, while solving an entire path would give you a bonus of eight. In the event of tied scores, the participant with the shortest time duration would be deemed victor.

The casual event required little technical expertise and meant to bolster easy participation. “It gave students a chance to take part in the fest from the comfort of their own room,” said Nivedita Nair, an event head for Alacrity.
