Following up on our Raspberry Pi programming course is the next lesson. In the previous post, we learned how to construct an FM radio using a Raspberry Pi. Analog FM broadcasting's circuit construction was also studied in detail. How to use a Raspberry Pi as an internet speed meter and save the data in Grafana or Google Drive is the subject of this article.
You can use this article if you want to keep track of how your downloads, uploads, and ping speeds change over time, and it's easy to use. In addition, you can use this to determine when your internet is at its busiest or if your internet speed has deteriorated. We'll demonstrate how to use Ookla's Internet speed test command-line interface in conjunction with Python code to create an internet speed meter.

Hello everyone! I hope you all will be absolutely fine and having fun. Today, I am going to give you an elaboration on Introduction to LM2575. LM2575 is specially designed to simply the design of switching power supplies. It can be done by providing all the necessary active functions required in Integrated Circuit (IC) for step down regulators. LM-2575 can deliver load current of around 1A along with the good line regulation as well as load regulation. LM 2575 has different builtin functions e.g. frequency compensation, cycle by cycle current limiting, oscillator with the fixed frequency and a lot more.
LM-2575 has many amazing features i.e. it can reduce the heat sink size due to its higher efficiency parameter. In some cases even heat sink is ...
Hello friends, hope you are doing good and enjoying your life. Today, I am going to introduce you to the Ethereum wallets. I have given you an introduction to blockchain, its characteristics, and an introduction to accounts in my previous tutorials, so let’s get started with today’s tutorial on Ethereum wallets.
What is Ethereum Wallet???
In this section, I will introduce you to the Ethereum wallet and then we will move into its further details.
A blockchain wallet is just like a real-life wallet but in software form. It is the digital form of a wallet.
A wallet is application software that acts as a user interface to the Ethereum network.
The wallet is a system to manage and store the keys.
This digital wallet allows transferring crypto ...
Hello friends, I hope you all are having fun. In today's tutorial, I am going to share a new Proteus library for Raspberry Pi 2. We have already shared the Proteus Libraries of other Raspberry Pi modules i.e. Raspberry Pi 4, 3, Pico etc. and we discussed that these Pi modules won't be able to read the Python code. We have just designed the external appearance of these modules and you can use these Pi modules for circuit designing and project presentations.We have also added the Arduino firmware in these boards, which is just to provide a bit of interaction with these boards. We have given these boards an unofficial title "Arduino Pi".So, let's have a look at How to simulate Raspberry Pi in Proteus:
Raspberry Pi 2 Library for Proteus
First of all, we need to download the Proteus Library ...
Selecting the right BLDC motor for electric vehicle applications involves more than comparing specs — cooling method is one of the most consequential decisions in EV powertrain design.Most guides tell you water cooling is "better." That's not wrong — but it's also not useful. This guide gives you the actual decision boundaries: what each cooling method handles, where it fails, and how to match your choice to your specific vehicle and duty cycle.
Why Cooling Is a System-Level DecisionThe cooling method isn't just a motor spec — it affects your entire drivetrain. It determines weight distribution, maintenance intervals, IP rating requirements, and total system cost over three to five years. Choosing based on motor specs alone is one of the most common ...

Hello friends, I hope you all are fine and having fun with your lives. In today's tutorial, I am going to show you How to use Arduino Serial Monitor. It's not gonna be a very big post but its really very essential if you wanna learn Arduino coding. Because Arduino Serial Monitor is a great debugging tool and it helps a lot in Arduino Projects. In the previous post we have seen How to use digitalRead in Arduino and if you recall that tutorial then you must remember that in it we have used some Serial printing. So that's what we are gonna cover in today's tutorial.
Before going into the details, I must suggest you to first read these two posts because in those tutorials I have shown the serial communication which is essential for Serial Monitor Work ...
As the cryptocurrency market continues to evolve, the importance of secure and user-controlled wallets has never been greater. Decentralized wallets, which allow users to retain full control over their private keys, are becoming the go-to choice for crypto enthusiasts.
These wallets not only provide enhanced security but also offer greater privacy and compatibility with decentralized applications (DApps). This post will explore the top five wallets available in 2024 to help you pick the best decentralized crypto wallet
for your needs.

Till now, we have read about the basic concepts and functions in the signal and system, but let’s have something that is more practical and practice each and every topic thoroughly because if you have the understanding at each point, transforming will become an interesting game for you.Keep in mind, that transforms are an important topic in signal processing, but they were traditionally taught in the same way they were discovered: through calculus. This approach, however, does not reveal the true purpose of the transforms or why they are desirable. Well, let’s check the topics that we are going to learn about today:
What are transforms?
Which common transforms are used in signals and systems?
What is the Laplace transform?
How can you implement the Laplace transform in MATLAB?
What ar ...
Imagine a real-time object counting system that is budget-friendly and easy to implement. You can achieve this goal with an ESP32-CAM. Today we will build an ESP32-CAM Object Counting System. This project is a combination of the power of embedded systems and computer vision.
The main processor of the system is ESP32-CAM, a budget-friendly microcontroller with an integrated camera. This tiny powerhouse captures live video streams and transmits them over Wi-Fi. On the other side, a Python-based application processes these streams, detects objects using image processing techniques, and displays the count dynamically.
Whether it’s tracking inventory in a warehouse, monitoring traffic flow, or automating production lines, this system is versatile and adaptable. You can implement this proje ...
