PCB Power’s PCB manufacturing review

Today I’m going to review one of the well-known PCB manufacturers in India, PCB Power.

PCB Power is a 20 years old Indian PCB manufacturing company located in Gujrat, it also provides PCB layout, component sourcing, assembly & stencil manufacturing services.

Over the years I have used PCB Power services many times in various projects but I wasn’t able to review them as the PCBs I worked on were for commercial projects. Currently, I have been working on a personal project which is an extension of my earlier project call Constant Current Dummy Load.

Below is the 3D rendering of the PCB in KiCAD in comparison with the board I got from PCB Power.

“Above image is not clear as my mobile was not able to take a good picture in indoor lighting, the board actually came out very good!”

SIAT 2019 from the perspective of Electronics Engineer

SIAT Entry


“Symposium on International Automotive Technology (SIAT), widely acclaimed by global automotive fraternity, is a benchmark biennial international event, organized by ARAI, that serves as a forum for exchange of ideas & brainstorming for the automotive industry, with participation of eminent worldwide experts in various automobile arenas.”

– Mrs Rashmi Urdhwareshe, Director, ARAI

The main reason to write this blog post is to create more awareness of this event mainly within the electronics community as this expo is one of the well-regarded expos in the automotive sector but many people working in the electronics industry are unaware of it. This is one of the best EXPO which I have visited in Pune, the sheer amount of innovation which was to be seen under one roof by top companies in the business was staggering. I also didn’t expect to see much electronics in the expo but I was pleasantly astonished to see the insurgence of electronics in the automotive sector due to rise in demand and investment in Electric Vehicles by the leaders of the automotive industry.

Following is a brief discussion of the innovative concepts and cool demos presented by various companies during the expo, I wish, I was able to spend more time in the expo to see all of the stalls more thoroughly and had documented each and every innovative or cool implementation I came across, but just brief stroll through each stall took me a whole day. Following photos and brief descriptions of the stalls is to give you an idea of what to expect and to get you excited to visit the SIAT 2021 as the expo happens ones every two years.

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”

(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.

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.

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
