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 ...
Hello guys! I hope you’re all in a good mood today because we are going to review the design of an interesting project today. We’ll be looking to design 4-way traffic lights in such a way that their delay is variable and is dependent upon the traffic density. This project is of intermediate difficulty level for people studying in undergrad engineering school with electronics, electrical and mechatronics as their major. It is also for the people learning Arduino and basic circuit design on their own or through some course. We have already designed a Simple 4-Way Traffic Light Control using Arduino and today we will make it smart by adding a variable delay.
Variable 4 Way Traffic Light:
As you all already know the importance of traffic lights and t ...
Manufactured parts need a quality surface finish and visual appeal before releasing them to the client or market. Although there are different methods of applying the surface finish, anodizing aluminum colors produce the best results.
There is a wide range of aluminum anodizing colors to choose from; therefore, product developers need to know how to color match before releasing the end product. Let’s examine more on anodizing aluminum parts, how to color anodized aluminum and the common anodized aluminum colors.
What is Aluminum Anodizing?
Anodizing is an electrolytic process that produces excellent mechanical properties to enhance aluminum parts' durability and visual appeal. Manufacturers use the anodiz ...
Hello everyone and welcome to this article which will be a great introduction to high-speed PCB design. For sure it is going to be a very interesting class. Let me start by posing a question; Is this something that you have ever come across in your world of PCB design? Where you spent too much time doing the schematics, selecting the right components, doing the footprint addition, generating the netlists, doing the proper layout and routing and sending the end product of your design to the manufacturer? At this level you might probably be designing standard types of PCB boards and if someone was to introduce a project that talks about signal integrity, reflections or even crosstalk, very much believe you will feel like a lost person. It might be s ...
Hello friends, I hope everything's going well. Today, I am going to share the 13th chapter in the PCB learning series, where we will discuss the single-layer PCB in detail i.e. definition, construction, advantages, manufacturing, applications etc. So let’s try to absorb everything about the single-layer PCB:
Single-layer PCB overview:
Just a quick recall, PCB stands for a printed circuit board having different electrical components connected with the help of pads and tracks of copper foil, incorporated on an insulating material(substrate).
Single-layer PCBs have only one conductive layer of copper. The PCB board itself has a total of 3 layers in single-layer PCB other than the copper layer which are substrate, solder mask, and silkscreen.
In the past, phenolic aldehyde was us ...
Hello readers, I hope you are all doing great. Welcome to the 2nd lecture of Section 5(ESP32 Sensors) in the ESP32 Programming Series. In the previous tutorial, we discussed the built-in ESP32 Hall Effect Sensor. In this tutorial, we will discuss another inbuilt sensor of the ESP32 i.e. Capacitive Touch Sensor.
ESP32 Board has 10 built-in capacitive touch pins, which generate an electrical signal when someone touches these pins. These ESP32 touch pins are normally used to wake up the board from deep sleep mode. These touch pins are also used to replace the normal mechanical buttons with touch pads, improving the presentation of the IoT projects.
Here's the video demonstration of the ESP32 Capacitive Touch Sensor:
Before going forward, let's first understand how this touch sens ...
In our previous article, we grasp knowledge about real-life examples of the Internet of things. Now in this article, we try to elaborate on real-life applications of the Internet of things. Now a question may arise in your mind what’s the difference between the application of the Internet of things and examples of the Internet of things. I would be happy if you may elaborate on your question in addition. Simply associate degree example shows how applications are also created. Like there are several functionalities on the market in terms of arthropod genus and strategies however with examples it might be additional clear. Even so these functionalities are also wont to produce one thing awe-inspiring. In short, examples of the Internet of things is a task that is performed to develop a skil ...
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.
Here's the video tutorial for ESP32 Bluetooth Classic:
ESP32 Wireless Features ...
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 everyone, I hope you all are doing great. Today, we are going to share the 9th chapter in the PCB learning series, where we will have a look at the difference between Through-hole and Surface-mount technology.In our previous lectures, we studied both THT and SMT methods separately and have seen that both are used for components mounting on the PCB board. So, today, we will have a look at the difference between the two techniques. So, let's get started without wasting any time.
Through-Hole vs Surface-Mount
Let us know have a look at these differences and get to know the way forward when it comes to the process of component selection whether SMT or DIP.
Definition - THT vs SMT
THT stands for through-hole technology.
In Through-hole technology, components are mounted by ...
