Resizing an Image Using OpenCV
OpenCV (Open-Source Computer Vision Library) is a powerful tool for image processing and computer vision tasks. One common task is resizing images, which can be easily accomplished using OpenCV’s built-in functions. Here’s a step-by-step guide to resizing an image using OpenCV in Python. Installation Before you begin, ensure you have OpenCV installed. You can install… Continue reading Resizing an Image Using OpenCV
LoraWAN Classes
LoRaWAN Device Classes · The LoRaWAN specification defines three device classes. Class A · At any time an end node can broadcast a signal. After this uplink transmission (tx) the end node will listen for a response from the gateway. · The end node opens two receive slots at t1 and t2 seconds after an uplink transmission. The… Continue reading LoraWAN Classes
Comprehensive Guide to Using the Emboss Tool in Fusion 360
Introduction to the Emboss Tool The Emboss tool in Fusion 360 allowed users to raise or recess text, sketches, or patterns onto the surfaces of 3D models. This tool was particularly useful for adding labels, logos, or intricate designs to models. Step-by-Step Instructions Step 1: Preparing the Surface Opened Fusion 360: Launched Fusion 360 from… Continue reading Comprehensive Guide to Using the Emboss Tool in Fusion 360
Nullish Coalescing (??) Operator
WHAT? It is a new Logical operator meant for short-circuiting to handle default values. It returns it’s right-hand side operand when its left-hand side operand is null or undefined, otherwise returns its left-hand side operand. WHY? To assign some default values to the variable if it is null or undefined we use nullish coalescing. On the other hand, if we use logical OR(||)… Continue reading Nullish Coalescing (??) Operator

Gas Tungsten Arc Welding (GTAW)
Gas Tungsten Arc Welding (GTAW), commonly known as Tungsten Inert Gas (TIG) welding, is a welding process that utilizes a non-consumable tungsten electrode to produce the weld. Here’s an overview of the GTAW process: 1. Equipment: Power Source: GTAW machines typically utilize a constant current (CC) power source, which provides stable control over the welding… Continue reading Gas Tungsten Arc Welding (GTAW)
Gas Metal Arc Welding (GMAW)
Gas Metal Arc Welding (GMAW), also known as Metal Inert Gas (MIG) welding, is a welding process that uses a continuously fed wire electrode and a shielding gas to create a weld. Here’s an overview of the GMAW process: 1. Equipment: Welding Power Source: GMAW machines use a constant voltage (CV) power source, which provides… Continue reading Gas Metal Arc Welding (GMAW)
