Simple Wireless Power Transmission Circuit to Glow an LED
The Wireless Electricity Transfer concept is not new. It was first demonstrated by Nikola Tesla in the year 1890. Nikola Tesla introduced electrodynamics induction or resonant inductive coupling by lighting up three light bulbs from the distance of 60 feet from the power source. We have also built a Mini Tesla Coil to transfer the energy.

Different Types of Transformers and Their Applications
A transformer is a widely used device in the electrical and electronics domain. It is an electromagnetic device which follows the basic principle of electromagnetism discovered by Michael Faraday. We have covered about Transformers construction and operation in detail in previous tutorial. Here we will cover different types of transformers used in different types of applications. However, all types of transformers follow the same principles but they have different construction method.

In this project, we are going to build a simple generator using an electromagnet and a fidget spinner to understand the concept of the electric generator.
Just like the craze for Pokémon Go out of nowhere the fidget spinners got popular and it became more of trend to have one of these spinning between your fingers. But lately people (including me) eventually got bored of it and hence in this project let us bring in a new purpose for fidget spinner by building a simple motor using Fidget Spinner. With this circuit you will be able to make the fidget spinner rotate forever with the help of basic physics and not worry about having it idle at some corner of your room. You will also learn the basic of how a Brushless DC motor works since the concept we are using here is same as that used in the famous BLDC motors.
There are mainly two types of switches- mechanical switch and electrical switch. Mechanical switches require physical or manual contact with switch for operation. Electrical switches not require physical or manual contact, it has ability to perform operation. Electrical switches operate under the action of semiconductors.
