The prototyping trap is familiar: an engineer glues together an elegant control system on an Arduino or ESP32, it behaves perfectly on the bench — and then fails on the factory floor. This article explains the practical thresholds where microcontroller-based solutions stop being appropriate and why a programmable logic controller (PLC) becomes the correct engineering choice.
The hardware divide: robustness vs. flexibility
Input/Output (I/O) voltages and signal integrity
Most MCUs operate at logic levels of 3.3 V or 5 V (TTL/CMOS). Those levels are fine for short, controlled interconnects on a workbench, but they are vulnerable to voltage drops, ground loops, and induced noise when the wiring runs meters across a plant. Industrial control syste ...
Hi readers! I hope you’re having a great day and finding something thrilling. Imagine being able to solve a problem in seconds that would take the fastest supercomputers millennia, that is, quantum computing. Today, we will cover Quantum Computing.
Quantum computing is a relatively new technology that can present a new way of thinking about how information may be processed using the laws of quantum mechanics. Classical computing uses bits, which are either 0 or 1, while processing information, whereas quantum computing uses qubits and has the possibility of being a bunch of things at the same time by virtue known as the “superposition”. In addition to "superposition", qubits can be connected across space through a property known as "Entanglement", which allows quantum computers the potent ...
Hi friends, I hope you are all well. In this article, we can discuss the scalar or dot products of the vectors. In previous articles, we have discussed vectors and their addition in the rectangular or cartesian coordinate system in depth. Now we can talk about the scalar product of two vectors, also known as the dot product. Scalar or dot products can play an essential role in solving the operation of vector algebra and also they have various applications in numerous fields like computer sciences, mathematics, engineering, and physics.
By doing the scalar or dot products, two vectors are combined when we can do their product, then they produce the scalar quantity which has both magnitude and direction by a single operation in a very efficient way. Simply the scalar and the dot product are ...
Hi readers! Hopefully, you are having a great day and exploring something new and advanced. In the competition to miniaturize electronics and increase performance, the smallest holes in your PCB, micro vias, are carrying the biggest load. Today, the topic of our discourse is micro via technology and its use for miniaturization in modern PCBs.
In this electronic revolution, the thirst for miniaturization, speed, and power will remain insatiable. Today's electronics scale down, complexity increases daily, from smartphones to wearable devices, from aerospace equipment to medical implants. Behind this miniaturization process is a key breakthrough in printed circuit board (PCB) technology, Microvia Technology.
Microvias are extremely small vias, usually under 150 microns in diameter, for ...
Choosing between 3D printing and CNC machining can be pivotal for manufacturers, designers, and engineers. Each method has distinct advantages, depending on factors like production volume, material requirements, and the complexity of the design. 3D printing offers unparalleled flexibility. It allows for rapid prototyping and intricate geometries that are difficult to achieve with traditional methods.
On the other hand, custom CNC machining
is known for its precision and ability to work with a wide range of materials, making it ideal for producing high-quality parts with tight tolerances. Understanding these differences is crucial for selecting the right technique for your project, whether looking to innovate quickly or produce durable, high-quality components.
This article will look a ...
Hi readers! Welcome to the next article on the MQ series gas sensors. Today, our motto is to learn about the basic information of the MQ137 ammonia gas sensor. We know that ammonia gas is extensively used in industries, agricultural lands, Environmental Monitoring, Health and Public Safety, etc. In such areas, there are great chances of leakage that can be harmful and here, sensors like MQ137 are used for the instant detection of the Ammonia gas. It is a colorless gas with a distinct pungent smell and its inhalation may cause eyes, lungs, nose, and throat infections and irritation. So, the MQ137 is specialized for its detection and acts as a life savior in such cases.
In this article, we’ll commence our discussion with the basic introduction of the MQ137 ammonia gas sensor and will ...
In today’s fast-paced software development landscape, ensuring developer productivity and collaboration is more crucial than ever. As organizations scale, the complexity of managing workflows, tools, and services increases, often leading to inefficiencies and bottlenecks. Internal Developer Portals (IDPs) have emerged as a vital solution, addressing these challenges by centralizing tools, streamlining processes, and empowering developers with self-service capabilities.
What Are Internal Developer Portals?
Internal Developer Portals (IDPs) are centralized platforms that serve as a single point of access for engineering teams to manage tools, workflows, and resources. They are designed to simplify development processes, reduce cognitive load, and streamline collaboration by integrating wit ...
Securing container images remains one of the most critical challenges in cloud-native development, as attackers and compliance requirements continue to evolve. Vulnerable images can be the entry point for devastating supply chain attacks and data breaches, especially as modern environments orchestrate thousands of containers across clusters and clouds. To counter these risks, advanced container image security platforms provide automation, hardening, and continuous protection that significantly surpasses traditional vulnerability scanning.
The Importance of Container Image Security in 2026
Containers have become the common language between development and operations, powering workloads in Kubernetes, OpenShift, and serverless architectures. Yet the shared responsibility model of cloud inf ...
Hello friends. We hope you are doing fine. The world is full of colours. Isn’t it? We humans can see and differentiate the colours very easily. But teaching robots and AI apps about colours is a real challenge. With the advancement of computer vision and embedded systems, this task has become easier than before. Today, we are going to make an RGB colour identifier using the ESP32-CAM. This project combines the power of OpenCV with the ESP32-CAM module to create a simple but effective system for detecting and tracking basic colors in real time.
System Architecture
1. Overview
This system consists of an ESP32-CAM module acting as a live-streaming camera server and a Python-based computer vision application running on a remote computer. The Python application fetches images from the ...
