TechTatva’16: Electrific

Do you think that making circuits is a piece of cake? You B.E.T! Electrific channeled one’s inner Tesla and challenged their ability to make the right connections.

‘Inalambrico’, meaning wireless in Spanish, required its participants’ to paint a working circuit with conductive paint. Round one of the event included a written test comprising sixty multiple-choice-questions, divided into two parts, technical and aptitude. Around thirty participants (in teams of two) took the test. Three wires were given to each team and the rest of the set-up would have to be completed using conductive paint. “Digital logic gates are to be used and not analog as that would make things really simple.” explained Raunaq Aman, the co-event head.

 A major challenge for the participants was the lack of ready-made paint which meant that they had to make the conductive paint on their own. Participants had to mix acrylic paint and graphite in appropriate proportions and test the paint’s conductivity. The diligence displayed by the participants had definitely paid off as they presented their prototypes to the judges, who were quite rigorous in their judgment. The event was well organised and innovative in its essence.

The event, Live Wire, tested participants’ knowledge of home wiring and the practical usage of electrical circuits. The event spanned over two days of TechTatva, with the first round being a written round, wherein each team was given an hour to solve a perplexing set of questions. The question paper challenged the participants’ aptitude as well as their logical and analytical reasoning The primary focus was on fundamental Physics concepts such as current and electricity. “The event is all about home wiring. We will give them the components, and they are required to design a circuit using the same”, said Siddharth, the Event Head of ‘Live Wire’.

Five out of the fifteen participating teams qualified for the second round of Live Wire, held on Day 3 of the fest. The task at hand was to home wire an electric circuit from scratch with the given components. The two problem statements consisted of a single-phase and three-phase AC circuit. With every incorrect circuit diagram or demands of a hint, three points were deducted from the total score. The judges looked for the most well-constructed circuit, with the most practical and economic feasibility. The event proceeded smoothly thanks to the organizers who were prompt and approachable

For Electrific’s event ‘Chess-o-bot’, the participants were required to make their own knight bots using Arduino UNO and Bluetooth modules.

Round one of the event consisted of an hour and a half long written test. The questions, as explained by the event head, were meant to test whether the teams could work in unison given a high pressure situation.

For round two, the seven selected teams built knight bots to play a game of electrical chess- focusing on making the least number of moves in order to shift the bots one point of the chessboard to the designated end. The event was judged based on technical soundness, and required the teams to make the least number of moves. If a team took more than seven minutes, or asked for a hint, marks were deducted.

The event was quite difficult which made certain that only the most technically fluent team would win. The category head Shreyash Sinha agreed, “While this is just a basic bot, it still tests a team’s knowledge of coding and ability of interfacing hardware and software. It also checks whether they can successfully implement their theoretical knowledge in a practical and effective form.” The event, as expressed by the participants was quite interesting and challenging as it required them to have equal parts of innovative thinking and technical finesse.
