My final year project: Top 35 in Mitsubishi Electric Cup

Hey guys,

Yeah! I am in my final year now and it’s time for my final year project. I had too many ideas for my final year project (which I was planning from my first year) and also had few friends from the industry who were interested in helping me with it. Which lead to too much switching from one idea to another. At last, we made our decision and started working on it.

Few days into it, we (me and my project partner Sagar) got an email from Mitsubishi Electric that our project proposal was selected in their Top 35 List for Mitsubishi Electric Cup competition which is all thanks to our guide who encouraged us (more like made it compulsory) to submit our idea for the competition.

Thus at the end, we ended up making our proposed project as our final year project.

Choosing right power supply for your project

Hey, guys, this is the second part of the series on the power supply if you haven’t read the first part (which is required to understand this part) of the series click here.

This is the simplest part of all in which we are going to see and understand power requirement of your project and opt Switch Mode power supply or Linear regulator for your application.

Understanding Power Supply- Linear and Switch Mode Power Supply

In need for power supply in your upcoming project?

Confused between Linear and Switch Mode Power supply?

or just want to understand how they work?

Let’s find you some answers-

This will be a three-part blog post

  1. Introduction
  2. Choosing Right Supply for your Project
  3. Design

PART 1: Introduction

It’s a long post so get comfy, bring your favorite beverage, take a deep breath and now lets start!

Let us try and understand what each of them really are and how do they differ.

Certainly if you are reading this you are a newbie so we will not go much in the complicated working (for now) of each and every component but we will try to just keep it simple and create just an intuitive understanding of each device. Continue reading

Completed! Mini Project – Self Balancing Robot (using Teensy 3.2)

Hey fellas,
Just completed my Mini Project- Self Balancing Robot it was awesome all my friends loved it, at the first go, none of them understood how it worked.  They were like, what does this robot (lying down) do ? Slide on the floor ? And when I turned it on and the robot started balancing and bobbling around like a baby, they were amazed. This reaction was only possible because most them have seen segway in some shape or form, but haven’t seen an unmanned implementation of the concept.

Working with MOSFETs

One of the most important component you will every encounter in electronics is MOSFET (Metal Oxide Semiconductor Field-Effect Transistor), it’s easy to use, can handle high voltages and high currents, have high switching frequency compared to BJT. And they are nearly everywhere. So it’s important to understand how they work and more importantly how to use them in practical day to day circuits.

UPDATE! Mini Project

Robot Frame

This is a small update on my college Mini Project – Self-Balancing Robot.
Till now we have bought all the parts need for the project (will update the BOM as soon as the robot is running)
The structure is very simple, we used old wooden switch board drilled four holes on its corners and used threaded metal rods with washers and nuts to secure the boards in place.
Used a standard pair of angled motor mounts to mount two metal geared motors and attached a 4cm diameter wheels.
So far so good! Will keep you guys and gals updated.

For people who don’t know about MAHA Tech, it’s an Industrial Exhibition, Trade Show of Process Industry and Electrical Industry that happens in Pune, … Continue reading

Mini Project : Self Balancing Robot

Hey! Fellow nerds!  Hope you are having a great weekend. Just a quick reminder the Chinese new year is starting from February 8th so Happy New Year to all my Chinese readers and for all other folks it just mean a Chinese electronics market shutdown for a month, hopefully you have stocked the parts you need.  I didn’t, was really in need for some motors and yeah shipping time 15 – 38 days, so going to try my luck in local market tomorrow.

Its my Sixth semester this time and that means I have to make a mini project and after a ton of pleading to my project guide, he accepted my project topic which I really wanted to do for a long time “The self balancing robot”.
This post will be about just some basic explanation and ideas I have for the project and info on upcoming in-depth posts on same.

PCB Manufacturing in Pune: Review

First of all Happy New Year fellow engineers !

This post is about reviewing PCB manufacturers in Pune. I had to start from scratch on this one, didn’t found any helpful post about this on the internet. So here is my note on the matter, hope it will be helpful. This post is based on the trial run of small quantity of PCB for my personal projects but few of the manufacturer I used also do PCB’s in quantity, contact links at the end of the post.
