Introduction

In school, I never really understood Physics, Chemistry or Electronics and so dropped them after class 10. But I was still fascinated by how electronics actually work. I thought circuits were extremely complex and complicated to understand which is why I never really delved deeper into the subject. But then after reading the course abstract and finding that there were no pre-requisites, I thought I could finally explore more into the subject of electronics as it will even be helpful in the future, no matter what field I choose. I feel that everyone must know basic amounts of electronics and circuitry, and especially us as artists and designers, as it broadens our knowledge and makes us more independent in our thinking approach without having to leave the technical stuff only to those who are already into it. And the extract also suggested a brief introduction to coding, which re-assured my decision of picking this course.


MicroRobots

Building our first robot

In every course, there's always the first-day excitement, curiosity and eagerness that's present in the classroom. So as I entered the class and saw all these components lying there, I was really keen on knowing how they worked and eager that by the end of the class, I hopefully would know how to operate at least a couple of these components. When we were told that by the end of the first class, we would make our very own robot, I was quite puzzled, as the word "robot" has some connotations synonymous with humanoids and Sci-Fi Hollywood movies. And there I was, getting excited after seeing one single LED light up as it came in contact with a 3v battery.

When we were shown the soldering iron, I was quite amazed at how it worked. I also thought Mr. Bala to be some sort of mad scientist when he told us all to touch the soldering iron to see if it was hot.


Trip to SP Road

When we were given the list of all the components, I half hoped the numbers next to each component would be its price. But alas, it was the quantity that we needed to buy. There went all my money.

The trip to SP Road was pretty exciting. Ganesh Chaturti was approaching and the streets were filled with Ganesh statues that were waiting to be immersed. They were spread all across Bangalore and so we encountered them all the way from Yelahanka to SP Road. In the car, we were discussing about how most of these components would not come in use and that after the course, we would take up our own projects and build from all the leftover components.

SP Road. Now when I even hear the name I can recall the whole place. It was nothing like I could have imagined. Before going, a few of my friends told me that it would be crowded with electronic shops and that it's a paradise of some sorts. Only when I saw the place with my own eyes did I understand what they meant.

When we went to Vishal Electronics, we realized that we had to withdraw money from an ATM. But when we asked around for the location of any nearby one, we were told that all of them are closed and that we need to go on the other side of the street to find it. We searched and searched for an hour and then finally found an Andhra Bank with an ATM in it. On the way, we saw a lot of shops which had so much equipment. We were in so much awe. Never had we seen such a place before; a place bustling with people, shopkeepers selling the same products setting stalls right next to each other, etc. It was a lot to take in.

Vishal Electronics was crowded with people. We were the first ones to reach and thought that by the time we were done buying our components, he would run out of items. Then slowly more people from class started flooding in until the whole class was gathered there. It took a really long time for all the components to arrive. And since all of them were bought in bulk, we could negotiate and come to an agreement for a discount in the price.

Intro to Components

Battery

Mini Project: Making your own battery

Making the lemon battery was an exciting project. When I was watching instructional videos on Youtube, I thought that once I learn to make this, I'd be able to power my laptop just with lemons. No, but in reality, I couldn't wait to get started with this. I realized, after searching around, that no shop in Yelahanka had copper wires, which were essential for the battery. So in the end, I found a shop where the man said he didn't have any copper, but I insisted he check his drawer and the shop and as he opened the drawer, I found some wire. It was very less, but it was something. And I managed with that. He was a little hesitant, but eventually he did give it to me. I also bought a multimeter from him.

At home, I started assembling my battery. I had copper wire, which I had to cut into pieces, just so I have enough. In the middle, I realized that I don't have enough nails, as I only bought 3, after all, the videos I watched had a requirement of only 3 nails. So I dug around the house and found some zinc sheet which my room-mate had used for his previous course. I cut out a bit of that and managed to make the battery successfully after a lot of tries.
