POV – Persistence of Vision using 5 LEDs

Definition –

“Persistence of vision refers to the optical illusion that occurs when visual perception of an object does not cease for some time after the rays of light proceeding from it have ceased to enter the eye. The illusion has also been described as “retinal persistence”, “persistence of impressions”, simply “persistence” and other variations.Wikipedia

So I wanted to make something for my sister on her birthday so I thought it might be cool to make a 5 LEDs POV display printing “HAPPY BIRTHDAY”

Part 2 : Final Year Project: Mitsubishi Electric Cup

(This is a continuation of the last post)

Day 1: Welcome

On day one teams where suppose to reach the venue which was College Of Engineering, Pune, with our projects. We then had to register us, find the stall we where allotted.

When we reached the venue we saw the grand arrangements made by the Mitsubishi, as we were near the venue there where lots of hoardings pointing us to the venue and advertising the event. After entry, we got near to the building where the event was supposed to be held there was massive hoarding of the Mitsubishi Electric Cup along the wall of the building, here is the picture we took.

Final Year Project: Won! 3rd Prize in ME Cup 2017

Engineering – It’s been a ride. Finally, I am an engineer and well it’s time to share with you all, my final year project.

Ya, I am a bit late.

This blog post is also intended to be a guide for the Mitsubishi Electic Cup, so let’s begin.

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.

#2 Update: Mini Project

Project is almost completed just having few problems with it’s overall weight, need higher torque motos. Anyway here are the latest photos.

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.
