Hello friends, I hope you all are doing great. In today's tutorial, we will discuss what is Selective Laser Sintering, why is it used for.
Selective Laser Sintering is a popular 3D printing technology used to create durable prototypes and end-use parts from CAD files. Its one of the oldest and most popular forms of additive manufacturing techniques and thanks to further technological advances, its use is becoming widespread. In this guide, we will explore what SLS is and what it is used for.
How does Selective Laser Sintering work?
SLS uses a nylon or polyamide powder which is spread successively in thin layers with a high-powered laser that selectively sinters the powder according to data derived from digital models. This process is repeated la ...
EEPROMs (Electrically Erasable Programmable Read-Only Memories) allow the non-volatile storage of application data or the storage of small amounts of data in the event of a power failure. Using external memories that allow you to add storage capacity for all those applications that require data recording. We can choose many types of memories depending on the type of interface and their capacity.
EEPROMs are generally classified and identified based on the type of serial bus they use. The first two digits of the code identify the serial bus used:
Parallel: 28 (for example 28C512) much used in the past but now too large due to having many dedicated pins for parallel transmission
Serial I2C: 24 (for example 24LC256)
Serial SPI: 25 (for example 25AA080A)
Serial - Microwire: 93 (for ...
Hello friends and welcome to this article. Today we are going to have a look at the introduction to the ceramic printed circuit boards. we have previously introduced what a printed circuit board is and we noticed that it is a very important part that makes electronic circuits complete and well organized. Having that in mind, we had also discussed several materials that build up these PCBs and today our focus is on the ceramic types of PCBs.
Introduction to Ceramic Printed Circuit Board
This printed circuit board is referred to as ceramic PCB because of the substrate used in the construction of this board is made up of ceramic and it finds applications in special areas.
The process of making this board is that copper is pasted on the surface ...
Hello readers, I hope you all are doing great. Welcome to Section 5 of the ESP32 Programming Series. In this section, we are going to interface different Embedded Sensors with the ESP32 Microcontroller Board. ESP32 development board is featured with some inbuilt sensors(i.e. hall effect sensor, capacitive touch sensor) so, in the initial tutorials of this section, we will explore these built-in ESP32 sensors and in the later lectures, we will interface third-party sensors with the ESP32.
In today's lecture, we will discuss the working/operation of the ESP32 built-in Hall Effect Sensor. Hall Effect sensor is used to detect the variation in the magnetic field of its surroundings. So, let's first understand What's Hall Effect:
What is the Hall Effect?
The Hall Effect phenomenon was fir ...
In the highly competitive world of electronics, it has become obvious for leading companies to stick to the adhere standards of quality and consistency. Hence, many times companies and organizations prefer to adopt globally known standards to maintain singularity and high quality within the organization. Because IPC is considered the gold of all standards, many companies and organizations tend to follow it. For that very same reason, companies always prefer employees who demonstrate his/her ability to deliver as per IPC standards. It is vital to becoming an established professional in the field of electronics assembly and quality inspection to find a suitable job in the field of the electronics manufacturing industry. What could be the better way t ...
Hello everyone and welcome to this article. Previously we have been discussing different types of PCB boards and for sure we have not exhausted everything. Today we are going to focus on a very important aspect of the PCB design which is the thermal characteristics of the PCB's working environment. Up to this moment, we have interacted with boards that work best in normal working conditions. But remember there are some working conditions, that have very harsh environment such as high temperatures. Let us take for example temperature in boilers or even electric heaters. Do you think normal FR-4 boards can survive in such temperatures? Don’t you think they will melt off if exposed to high thermal radiation? Your guess is as good as mine. For us to h ...
Greetings and welcome to today’s lecture. Today, we are going to focus our discussion on the Surface Mount Technology of PCB components mounting. It's our 8th tutorial in the PCB learning series and is going to be a very interesting and interactive class. In Surface-mount technology, SMT components(having small pads) are
placed on the surface of the PCB board and their pads are soldered on
the same side of the board.
As we discussed in our last lecture on Though-Hole Technology, there are two main methods used to mount components on PCB boards. We studied THT in the last lecture and today, we will focus on
Surface Mount Technology (SMT), we will discuss SMT classifications, types, applications, advantages and disadvantages in detail.

An Analog to Digital Converter (ADC) converts a continuous signal (usually a voltage) into a series of discrete values ??(sequences of bits). The main features are:
Resolution (in analog terms): It is the minimum variation of the analog input voltage that can determine the variation of the LSB, that is of the least significant bit of the output code. Since the quantization step Q corresponds to the LSB, it can be said that the resolution coincides with the quantization step Q (and therefore is measured in Volts). We can say that the quantization step Q corresponds to the LSB because two contiguous quantization bands, each of amplitude Q, are identified by codes that differ only for the least significant bit.
Resolution (in digital terms): It is the number n of bits present at the co ...
Hello readers, today we will learn about the messaging protocol supported by ESP32(called MQTT protocol), which is used for IoT applications. The communication protocol to be used for data transmission and connectivity in web-enabled devices depends upon the type of IoT application.
The Internet of Things (IoT) is a network of interconnected computing devices like digital machines, automobiles with inbuilt sensors, having unique identifiers and the ability to communicate data over a network without the need for human intervention.
Before implementation, let's first have a look at what is MQTT Protocol?
What is MQTT?
MQTT stands for Message Queuing Telemetry Protocol and is a messaging or communication protocol used for IoT applications.
In MQ ...
Hello readers, I hope you all are doing well. Welcome to the Section 2 (ESP32 Features) of the ESP32 Programming Series. ESP32 is equipped with numerous built-in features and in each chapter of this Section 2, we will explore one of these ESP32 features in detail.
In the previous Section(Section 1: ESP32 IDEs), we installed different software IDEs to program ESP32 boards. Among these IDEs, we are going to use Arduino IDE for programming ESP32. So, I hope all of your tools are configured properly and you are ready to explore the built-in features of ESP32.Today's the 1st Chapter of Section 2, and here we will discuss How to communicate with ESP32 Bluetooth Classic from a smartphone using Arduino IDE.
