Datum.
Parts are composed of a number of surfaces, each surface has a certain size and mutual position requirements. The requirements of the relative position between the surfaces of the parts include two aspects: the dimensional accuracy of the distance between the surfaces and the relative position accuracy (such as axes, parallelism, verticality and circular runout, etc.).
The study of the relative position relationship between the part surfaces can not be separated from the datum, and the position of the part surface can not be determined without a clear datum. In its general sense, the datum is the point, line and surface on the part on which the position of other points, lines and surfaces are determined. According to its different functions, the benchmark can be divided into two cat ...
What Is MIG Welding?
MIG welding is the process of joining metal parts by melting the base metal and fusing it with a filler metal. The name is derived from the phrase "Metal Inert Gas," which is commonly used. The process involves using an arc between an electrode and the workpiece, which melts the base metal and fuses it with the filler metal.
Mig welding is an extremely versatile process that can be used to create virtually any shape or configuration of the welded joint. You can also use it for many different metals, including low carbon steel, stainless steel, and aluminum alloys.
Mig Welding Equipment
The MIG welding equipment you'll need includes:
Torch
The torch supplies the heat needed to melt the wire. It has a handle, an on/of ...
Hello friends, in the previous tutorial we learned about ions and now I am coming up with a new article Molecular ion. In this article, we will discuss the formation of molecular ions. When we discuss molecular ions many types of questions arise in our minds. I hope after reading this article you can answer these questions which are given below:
What are molecular ions?
How many types of molecular ions?
How molecular ions are formed?
Why is NH4 + not a molecular ion? Give a reason.
Which type of molecular ions structure exists etc.?
Which example is suitable for molecular ions or not?
Discovery
In 1794, molecules were considered a minute particles according to the French. Latin used vogue words for molecules until the late 18th cent ...
Hello readers, I hope you all are enjoying our Raspberry Pi Pico programming series. In our previous tutorials, we learned how to access Raspberry Pi Pico’s GPIO pins for both input as well as output operations. For demonstration, we used LED as an output component and a push button as an input component.
Now let’s learn how to interface sensor modules with the Raspberry Pi Pico module. So, in this tutorial, we will learn how to interface the DHT11 sensor with the Raspberry Pi Pico module and fetch the observed data (from its surrounding) using the MicroPython programming language.
Before writing the code for interfacing and fetching the data from the respective sensor, let’s first have a look at the working operation, features and properties of the DHT sensor.

Hello, students here in our previous tutorial we study molecules and now I am with a new topic “Ion” which might be possible for some of my readers this article seems to be new, and some of my readers may be familiar with this term. But no matter whether we know or not, in my article I try to cover all aspects of this term. Many questions arise in your mind such as you may think;
What is an ion?
How ions are formed?
What are the different types of an ion?
What methodology is utilized for assigning charge to an ion?
What are examples of an ion?
Which methods are used for the creation of an ion?
If my readers want to know the answers to these questions, hold copies and pencils in your hand and stick to my article till the end.
Brief description of an Ion

Hello, friends today we will discuss the basic concept of chemistry it is our first tutorial series in which we will discuss:
Atom
Molecule
Ion
Molecular ion
Now in this article, we will discuss atoms. Its definitions, examples, properties, its evolutionary history, and also some important facts in the form of questions.
Atom
Definitions
A tiny particle that cannot be seen with a naked eye so-called atom.
Or
Atom is the lowest unit of matter and is often divided without the discharge of electrically charged particles.
Or
Atom is the introductory structure block of chemistry.
Examples
From molecule;
Hydrogen (H2)
It has two atoms.
Nitrogen (N3)
It has three atoms
From elements;
Helium(He)
It has two electron
Properties
We discuss different properties of atoms ...
Hello readers, I hope your all are doing great. We know that a Raspberry Pi Pico module comes with multiple inbuilt features for example onboard memory, processing units, GPIOs or General Purpose Input Outputs (used to control and receive inputs from various electronic peripherals) etc.
In our previous tutorials, we discussed how to access GPIO pins of the Raspberry Pi Pico module for both input as well as output operations.
In this tutorial, we are going to discuss another important feature of the Raspberry Pi Pico module (RP2040) which is Dual Core Processor. The Pico board features with 133MHz ARM Cortex-M0+, Dual Core Processor. This dual-core feature makes the Pico module capable of multiple thread execution or multithreading.
Now before writing the MicroPython program let’s first un ...
The Industry 4.0 market size will reach $267.01 billion by 2026. Industry 4.0 depends on the secure, fast, and cost-effective data transfer between IoT devices. IoTA is designed to ensure secure communication between two devices within the IoT(internet of things) framework. Let's have a detailed look at the role of IoTA in industrial IoT.
Understanding IoTA- how it's different from blockchain
The terms MIOTA and IoTA together make up the term IoTA. While MIOTA is a cryptocurrency, IoTA is a non-profit foundation. Since its inception in 2015, IoTA has formed joint ventures with firms like
Fujitsu
Samsung
Telekom
Volkswagen
IoTA is technically different from blockchain in terms of the underlying technology. IoTA works on a technology ca ...
Welcome to the next tutorial of our Raspberry Pi programming course. Our previous tutorial taught us how to use a raspberry pi as a DNS server. We also looked at the benefit of this DNS server. This tutorial will teach us to set up Raspberry pi as a VPN server.
This is an excellent method for increasing your network security and getting access to your local area network from the world wide web, but setting up your VPN server might be a challenge. Pi VPN uses a guided install to turn your Raspberry into a low-cost, high-performance VPN server.
What is Pi VPN?
It is an OpenVPN server optimized for all Raspberry platforms above pi 2. It allows you to access your home network over the internet safely and securely. Smart devices and your network can ...
Hello, Students here I am present to cover an article on a series of Electronic devices and circuit theory. The foremost article of this series is Ideal diode vs practical diode. I try to elaborate on basic to modern theory related to the diode. This component act as fundamental to many important circuit devices such as rectifiers, transformers, etc. The question which we cover in this article are;
What is a diode?
How a diode is formed? Which methodology manufacturer utilized while the formation of the diode?
