What's Your Biggest Achievement?

What do you consider to be your biggest achievement?

Yeah, that's a question you may be asked during an interview. I have been interviewed 6 - 7 times, but that question never popped up. So I thought I'll share what I consider to be my biggest achievement.

I was in 8th grade when the remote controller of our TV started causing problems. The technician told us to buy a new one. He said that the controller was causing problems because of some carbon layer. My dad bought a new remote controller and threw the old one in the trash can. I was sad to see my old buddy die. So I took it out of the trash can. I knew what I was gonna do... "I will fix it!".

I always had a keen interest in electronics. Every time a new gadget came into our house, I would open it up to see how it was made and eventually break it. I was fascinated by electronics gadgets. "How does this work! How can a iron rod send my voice!" These question bugged me during childhood. I hoped to find answers by opening things up. Though that didn't happen, I did, however, become familiar with electronics components. Eventually I enrolled for an engineering course on Electronics and Communication to find those answer. I did find some answers. But what I realized, people weren't there for finding answers.... But that's for another post.

I opened the remote controller but I had no idea what I was doing. Do realize that this was way before I got into the engineering course. I looked around and assumed that the integrated circuits, capacitors and resistors weren't damaged. "So the cause of the malfunction must lie in the buttons", I told myself. I figured that the buttons must have some kind of conductive layer on them that connects the two buses together when pressed. But this was just an assumption. I needed a proof before I could think of a solution. So I put a few drops of water on my finger and touched the two buses. It worked! Eureka! Now I needed to figure out how to bring back the conductivity on the buttons.Obviously water wasn't going to work as a permanent solution. I cut little pieces of copper and stuck them under the buttons with adhesive. But it changed the soft tactile feeling of the buttons. And after a few presses they stopped working. I needed to come up with something else.

I listed down the requirements for my next material.

  • It needed to conduct electricity
  • It had to be soft and easily applicable as a thin layer
  • It had to be available in the household or in shops at a low cost

So what's your biggest achievement? Let me know in the comments section below.

As I was thinking about the possible choices, I remembered what the technician said... "a layer of carbon" and instantly I remembered what I read in the Physics book. Graphite is a polymorph of carbon. It conducts electricity. It is soft (presumably easily applicable). I had found my material! But where will I find Graphite? And then, I remembered another lesson I had learned. The lead of a pencil is made out of Graphite. Pencils are available in any household. So I scrubbed off the lead and applied the dust to the buttons. And ta-da! It worked! It worked! I felt like I had made a new discovery. It was an amazing feeling; to fix an electronics device just by connecting the dots.

Why I Started Blogging

It's been almost 5 years since I started blogging. This is the 30th post being published. That means over the course of 5 years, I've written 6 posts per year. Although 30 is much less than I would have liked, this is one of those pet projects I have continued even after the honeymoon phase. Today I want take some time and discuss why I started this blog in the first place. I was in my 3rd year of engineering studies when I started out. I had already developed a keen interest towards programming and tech in general by then. Having a blog seemed liked a cool idea. There were couple of more reasons to go ahead with this idea. That's what we are here to discuss today. Setting up a blog seemed like a technically challenging task. I wanted to know how to setup a blog with comments, advertisements and with a custom domain. It sounded like a great way to acquire new skills and learn new things along the way. Back then I didn't know anyone who shared my enthusiasm for tech

Dear edX!

Dear edX, I was in my 2nd year of college when you came to life. And I was ecstatic! No, not to be in college (LOL) but to have finally found my calling. Computer programming. I was browsing through all the resources I could find. Codecademy courses mainly. And right at that moment, you arrived. Your parents hail from the Harvard University and from the MIT. So of course you received my attention. Also, you had an unique selling point: free certificates. This was huge! No one else was doing it. It seemed you were actually trying to help students learn new skills and show off to the world. I was stoked to enroll into the course developed world's top professors. The free certificates were a big motivator to complete the courses. The first course I enrolled into was developed by The Linux Foundation. I have taken several courses since then. Some were on computer programming, some were about a country's history and some provided advice on career growth and personal finance. 2

It's Time India Gets Cashless Payment

India just had a mobile network revolution yesterday; thanks to Reliance Jio. It's time India gets another long-due technology i.e. mobile payment. There are many advantages of using mobile payment over cash or ATM cards. You are less likely to lose your phone - assuming you fiddle with your phone as much as I do. Even if you lose your phone, you can at least try to track it down using GPS. Your phone doesn't physically deteriorate over time. No need for mints. No wastage of paper. It's environment friendly. No maintenance needed unlike ATMs. More secure than ATM PIN codes. Mobile payment uses your fingerprints for verification. Mobile payment is much more convenient. Your employer transfers your salary to the bank and you can directly pay from your bank account. No need to withdraw the cash and hand it over to the merchant, who eventually does the reverse process after they received the money. Such waste of time. Instead just bring your phone or watch close to the

Why Do We Still Pay for Voice Calls?

It's 2015. We have self-driving cars, mobile devices that rival laptops built 3 years ago, gigabit Internet connections and still, service providers make us pay for voice calling and SMS. That seems to be the dumbest thing to me. Let me explain... There are generally three things that you do on your phone, that needs to communicate with the network. First, there is voice calling, then there is SMS and lastly, there is web browsing and other stuff that requires an Internet connection. Now, put simply, Internet is all about sending data up and down, and if you think, SMS is also data. If we had a system, SMS can also be sent using the Internet. No I'm not talking about free SMS services here. Some of you might argue if we really need to have the SMS feature, but that's a different story. And then there is voice. VoIP anybody? That's been out there for ages! Why not route all the voice calls through the Internet? That's a question I'd like to ask the service
