CIRCUITS: Electronic Circuits Have To Be Designed – Not Assembled
Now-a-days, designers tend to use off-the-shelf designs and software available on the Internet or from the vendors to design products requisitioned by their clients. While this may be unavoidable in certain circumstances, their rampant use without understanding the factors involved can land them In problem. Here are some important suggestions from a person who has seen it all for such designers

MY STORY: “Won’t Retire Until Semiconductor Manufacturing Starts In India” — Raja Manickam, CEO OSAT, Tata Electronics
It was one of those days when we were looking for answers to the semiconductor ecosystem in India. We had interacted with a US based Indian a few days back. He, in the process of setting up a power semiconductor product fab in the country, had shared his ideas on how India could have a complete ecosystem of semiconductor fabrication to services.
We put together his story and sent a thankyou note to him. In reply, he texted, “You must be happy, the Tatas are entering into the semiconductor game!” When we asked him whether he knew who was going to lead the semiconductors project for the Tata Group, he answered, “A gentleman who has dedicated his life to semiconductors and society.”
The gentleman is none other than Raja Manickam himself, who has worked with several semiconductor companies and founded one that was acquired by a corporate group. Not many professionals would know but he is also a trained army combat tank commander. This is Raja Manickam’s story as told to Mukul Yudhveer Singh, Business Editor, EFY

Control Lights Through Thoughts Using EEG Based IoT Controller
Have you ever thought of controlling things with just your thoughts? Well, it is now possible! The idea for this project came while working on BioSecure project wherein a unique pattern was created using EEG and EMG signals to act as a unique password. This led to the development of a machine learning (ML) model that understood brain signals and thereby created unique patterns using our thoughts. For example, when thinking in a particular language, the ML model is able to read those thoughts and translate them

Linear Speed Control For DC Motor
Here is a simple, low-cost project to control the speed of a DC motor linearly for specific and precise applications. Normally, pulse-width modulation (PWM) is used for varying the speed of DC motors. When width of the pulse is fixed, the speed of motor remains the same, and when its width changes, the speed also changes

Contactless Hand Sanitiser Dispensing System
Hand sanitisation is important to stop spreading Covid-19 and other transmissible diseases. Even touching the container spout is unhygienic, so it is better to deploy an auto-dispenser to sanitise your hands without touching anything except the sanitising liquid. It can be useful especially for industrial units, workplaces, hospitals, and shopping centres, etc
