Diesel Engine, How it works ?

Diesel engines are the most versatile IC Engines. With help of animation working of Diesel engine is elaborately explained in this video. Here the basic construction of diesel engine, its working and mechanical design aspects are covered. Starting from working of single cylinder diesel engine, working of a four cylinder engine is logically explained here.    

Petrol (Gasoline) Engine vs Diesel Engine

Have you ever wondered why there exists 2 different engines, Diesel and Petrol (Gasoline) ?. This video is aimed at giving a logical illustration of differences and advantages of diesel and petrol engines. It also answers the questions like, what if I put petrol into a diesel engine or vice versa.    

How do Airplanes fly ?

This video demonstrates the airplane operation in a logical manner with help of animation. Please check out a video by a Cambridge professor to clear your misconception about the lift generation.  

How does a Transformer work ?

This video gives a detailed animated illustration on the working of electrical Transformers. Here the basic working principle and construction of transformer, step-up transformer, step-down transformer, transformer winding and core construction are well illustrated.    

Transformer Winding types

Different types of transformer windings employed in practise are explained in this video with help of animation. The winding types explained are disc-type, cross-over, helical and sandwich.    

DC Motor, How it works?

The working of a DC motor is well explained in this video with the help of animation. Construction details of DC Motor, Shunt & Series motor, concept of back EMF are also explained in this video.    

Manual Transmission, How it works ?

Working of a Manual transmission is explained in an illustrative and logical manner in this video with the help of animation. Here the working of Sliding mesh and synchromesh transmissions are well illustrated. This video also explains the working of a reverse gear.    

Degrees of Freedom

The concept of DoF is well explained in this video lecture with the help of animation of mechanisms. This video covers the topic of a higher pair, lower pair and mobility equation. Degrees of freedom of 4 bar linkage, cam and follower mechanism and 5 bar linkage are worked out here.

Interface / connect Raspberry pi to a PC monitor and Laptop

Today we will be learning how to interface /connect Raspberry pi to a PC monitor and Laptop Last week, I hope we have finished how to burn RASPBIAN image (OS) file in to Memory card. Now, Let us look at the ports of Raspberry pi: Out of the ports we have as shown in the above figure, we will be using only HDMI, Ethernet and Audio and video jack to connect to PC monitor /Laptop/TV Respectively. Interfacing of Raspberry pi with the above depends on the individual, his availability and his requirements. HDMI interface: With the HDMI port available on…

Getting started with Raspberry Pi

Hello Everyone, here is our first weekly updating blog on a specific technology. Today we will be starting with ‘Raspberry pi’.   What is a ‘Raspberry pi’? If you Google the same thing, you will be seeing it as a low-cost, small credit-card sized computer.   Yes, It is a credit card sized computer which can easily be connected to a display just as TV or PC’s monitor and there are many other displays such as TFT screens, LCD screens specially designed for ‘Raspberry pi’ with different sizes. As  every computer has an OS to access the system, Raspberry pi also has OS…

What is the concept behind gyroscopes and accelerometers?

Here is an excellent explanation of both Accelerometer & Gyroscope. Source: A Guide To using IMU (Accelerometer and Gyroscope Devices) in Embedded Applications. Acclerometer When thinking about accelerometers it is often useful to image a box in shape of a cube with a ball inside it.. You may imagine something else like a cookie or a donut , but I’ll imagine a ball: If we take this box in a place with no gravitation fields or for that matter with no other fields that might affect the ball’s position – the ball will simply float in the middle of the box…..
