Maintaining and modifying the complex engineering drawing on paper is very tedious job. AutoCAD is computer software which allows to user to draw and modify 2D and 3D drawing in easy and fast way. The first version of AutoCAD was released in 1982 on Windows operating system. It is maintained and developed by Autodesk . It is available in 14 different languages. User can customize this software according to their project requirements. It is widely used in mechanical, civil, electrical, electronics and communication industries. Autodesk is providing free student version of AutoCAD software for learning purpose. It is a great opportunity for students or learner to have such industry leading software for free! General features of AutoCAD AutoCAD is a complex software it has almost every feature for drafting. Out of them some general features are listed below. Draw to scale Smart dimensioning tools Draw in any unit system Infinite drawing area Smart Draw Tools for 2D and 3D drawing ...

AutoCAD is a computer-aided design and drafting software popular in engineering students and professional to draw and edit 2D and 3D drawing. AutoCAD is owned by  Autodesk  an American multinational software corporation. There are large list of tools available in AutoCAD to draw and modify the 2D and 3D drawings. Some basic tools are offset tool, copy tool, move tool, erase tools . All these Tools are listed in the Modify Tool Panel under the Home tab. Different procedures to erase the objects in AutoCAD. Select the object you want to erase Press Delete key on the keyboard. All the selected objects will be deleted. This is the easiest way to erase any object. The Erase command. Erase command does not move objects to the Clipboard. That means they cannot be pasted to another location. How to activate the Erase Command? The most popular methods to activate Erase command are: Go to the Modify Tool Panel under the Home tab and left-click on the erase tool. Type E in the comm...

Today, we will do a small but interesting project of measuring humidity with DHT11 (Humidity & Temperature Sensor) using an Arduino board. We will use Proteus 8 for simulating this project. Proteus is a very well-known software used mainly for electronic design automation. It works in real-time and is a very fun way for circuit simulation. So let's get started!! First of all, you can find the DHT11 sensor in the proteus library but you will not find Arduino Uno there. So, we have to download Arduino Uno for Proteus. You can simply search for this on Google or you can download it from here .  After downloading you will get a zip file. On unzipping the zip file, you will see three files:- .IDX File .LIB File .txt File Copy the first two files and paste them into the Library folder inside the Proteus folder in the C drive of your computer. Windows users can follow this path: - This PC -> C: -> Program Files (x86) -> Labcenter Electronics -> Proteus 8 Professionals -...

World War II can be considered as one of the most destructive military clash of our recent history. According to an estimation around 70-85 million people died in the span of 6 years between 1939-1945. But we all must have heard that old saying, "Necessity is the mother of inventions". This time of crisis acted as a catalyst in bringing forth many new inventions. People were facing a massive global conflict and they need more and more of everything. Military needed more advanced weapons, more faster and secure communication and common people needed better health facilities and more security. These demands encourages scientists and inventors to design and invent new products. Some of these innovations played a major role in victory and had a significant impact on common  people's lives as well. Some of the technologies designed for winning war found use as commercial products as well.  In this article we are going to discuss some of the most important innovations of Wor...

  What is Git? Managing files for a big software is a very difficult task. It may consume lots of time and memory. Therefore, you need a software that can manage the changes in files and folders and save these changes for future reference. Git is a Version Control software that provides all these features for a programmer. Git is a Distributed version Control System (DVCS). In DVCS clients don’t just check out latest snapshot of the file; rather, they fully mirror the repository, including its full history. Thus, if any server dies, and these systems were collaborating via that server, any of the client repositories can be copied back up to the server to restore it. This feature makes git very helpful tool for programmer to manage their project. When we install Git, an application called Git Bash comes with it. It provides command line experience on operating system and support Linux command. Bash is a popular default shell on Linux. Installing Git Bash 1.You can easily dow...

With the introduction of smart and more energy-efficient housing, the need is there for construction to get smarter and more efficient too. With more innovative tools and techniques appearing all the time, here are five industry-changing examples of the new technology used in civil engineering today. Self-healing concrete Cement is one of the major construction material, but also one of the largest contributor to harmful carbon emissions.  Cracking is a major problem in construction, usually caused by exposure to water and chemicals. Researchers at Bath University are looking to develop a self-healing concrete, using a mix containing bacteria within microcapsules, which will aid building innovation by germinating when water enters a crack in the concrete to produce limestone, plugging the crack before water and oxygen has a chance to corrode the steel reinforcement. Photovoltaic glaze One of the most exciting new technologies used in civil engineering is building integrated p...

In the field of AI, researchers are working on devices having their own memory and ability of thinking, they are trying to mimic the human brain. The human brain is the most complicated structure consisting of millions of neurons that are interlinked by a thread-like structure called synapses. The engineers from the Massachusetts Institute of Technology have designed 'brain-on -a-chip'. The chip is smaller than a piece of confetti, that is about 1 mm in dimension and made from thousands of artificial brain synapses known as Memristors. Memristors are the silicon-based component that mimics the information-transmitting synapses in the human brain. Memristors or memory resistors are the necessary elements of neuromorphic computing. In a neuromorphic device, memristors would work more similar to a brain synapse. The synapse receives signals from one neuron, in the form of ions, and sends a corresponding signal to the next neuron. Like a brain synapse, a memristor would also be...

In series of posts celebrating the success of ISRO, this is our third post and in this, we are going to remember a milestone of ISRO's journey, Chandrayaan-1.                                                                                                                      pic by:- Universe today Chandrayaan -1 was India's first mission to the moon. It was launched by ISRO in October 2008 and it was active until August 2009. The mission was a significant uplift to India's space program as most of the technologies used were developed in India. This mission is well known for the discovery of evidence of water molecules on the moon. MISSION HISTORY & OBJECTIVE The word...

In the continuation of our previous blog, it turns to introduce you with further missions of ISRO ..... After Rohini satellite mission next in the row was ASLV mission.                ASLV: ASLV ASLV stands for Augmented Satellite Launch Vehicle. It was all started to expand the payload capacity to 150 kg which is thrice of the previous SLV-3 so that satellites weighing more than before can be placed I to lower earth orbit. It's a five-stage program. ASLV  project develops technologies to place the payload into the geostationary orbit of Earth and also mastered many technologies like strap-on which helped in the development of PSLV. Under this project, four developmental flight was conducted from the Sriharikota launching pad. ASLV-D1 was the first developmental flight, took place in March 24,1987, was carrying satellite SROSS-1 and other scientific instruments. It was not successful. ASLV-D2 was the second developme...
