Hi readers! Welcome to a detailed exploration of the MQ gas sensor series where we are discussing the basic details of its members. This series was engineered using revolutionary technology to detect combustible and toxic gases with great efficiency. It uses the chemiresistor sensing element to detect the target gas and has a quick response time that makes it a reliable choice. These are used in multiple industries, domestic areas, offices, and other places where a chance of leakage of combustible gas occurs. This series might not be fancy, but it is designed for a long life and ensures minimal false detection for reliable output.
We are going to start the discussion with a basic introduction to this series, and then we’ll try to clear up some basic concepts in order to have the best unde ...
Vacuum casting is the key technique for plastic or rubber part fabrication using a vacuum and stands out as a premier method for small batches of polyurethane products. This method is particularly valuable for the creation of samples of products so the manufacturer can assess the trend, market response, customer feedback, and product performance before working on full-scale production. Injection molding is another technique used for plastic model manufacturing, but vacuum casting is cost-effective and most suitable for small production. This article will shed light on the vacuum casting introduction, its working principles, pros and cons. Let’s discuss each point in detail.
Vacuum Casting Definition
Vacuum casting, also termed polyurethan ...
I remember the first time I handed off a PCB project without thinking hard enough about the assembly process. The board came back looking fine. Then we started testing. Footprint mismatch on a critical power IC. Wrong polarity on an electrolytic cap. Two components missing entirely. Three weeks of schedule gone. The factory had done exactly what we asked them to do. The problem was what we asked for.That experience taught me something most engineering programs never cover. The assembly model you choose matters as much as the circuit design itself. And turnkey PCB assembly is one of those decisions that gets made too casually, too often.What Turnkey PCB Assembly Actually Means
The word turnkey gets used loosely in manufacturing. In PCB assembly it ha ...
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 ...
Hey there, I hope you are having a good day. Printed circuit boards (PCBs) are a popular topic in the electronic world and we also know that PCBs have revolutionized circuits. They not only provide a solid base but the material used in the PCBs helps the circuit to function properly by protecting the circuit from factors like external radiation. These are present in different materials that divide the working, stability, and reliability of the circuit. In recent years, there has been a significant change in the types and strength of PCBs and this depends on the materials used in the manufacturing of these boards. We are interested in studying the advanced materials used in the manufacturing of PCBs and knowing the right type of material for the right circuit.

In 2025, the Internet of Things (IoT) is transforming business operations with a projected market value exceeding $1 trillion. With over 18 billion connected devices expected by year-end, IoT drives efficiency and innovation. However, generic solutions often fail to meet unique business needs, making custom IoT development essential. Tailored systems enhance scalability, security, and performance, helping companies stay competitive. This article explores why custom IoT solutions are critical for businesses in 2025.
The Evolving Landscape of IoT in 2025
The IoT ecosystem is transforming at an unprecedented pace, influenced by advancements in edge computing, 5G networks, and artificial intelligence. In 2025, businesses face a deluge of data from interconnected devices, demanding systems th ...
A common requirement for technical professionals working on electrical projects is to understand wire sizing, including the differences that can apply to how this aspect is handled around the world.
One conversion that frequently needs to be made for electrical projects is from American Wire Gauge (AWG)
to square millimeters (mm2). The latter is a measurement of the actual physical area of the wire’s cross-section, known as the cross-sectional area (CSA).
The Background of AWG Conversions to Square Millimeters
The fact that wiring systems vary internationally – AWG being commonly used in North America, while many international codes stipulate that conductor sizes be specified in mm2 – means that if you are responsible for this aspect of a project, you will need to be vigilant in your ...

Do you often record videos to post on social media or for work? If yes, then you know the real struggle to remove object from video or to erase people from frames. Even if you record carefully, the unwanted people can show up in the background of a shot. This can obstruct your subject and can affect your views on YouTube, Instagram, Facebook, and other platforms.
For content creators, marketers, and businesses, an unprofessional video with anyone walking past can impact the overall quality and professionalism. In many instances, reshooting isn’t an option, and most editors need to use painstaking techniques such as frame-by-frame masking and rotoscoping, which is time-consuming and needs advanced video editing skills.
The good news is that now you can quickly remove person from video wit ...
