Introduction 3D printing refers to the processes used to synthesize three-dimensional objects in which successive layers of material are formed under computer control to create an object. In 3D printing, the 3D model is sliced into hundreds or thousands of thin layers and then the object is built layer-by-layer from the bottom up. The history of 3D printing can be traced back to the 1980s when the first 3D printing patent was issued to Charles Hull in 1986. Since then, 3D printing technology has evolved significantly from being used primarily for prototyping to having widespread adoption for finished products across industries like aerospace, automotive, architecture, consumer products, medical devices, and more. The expiration of key patents and the RepRap open-source 3D printer project played crucial roles in making the technology accessible to a wider audience. Today, 3D printing has become mainstream and is fundamentally transforming manufacturing and business models across industr...

Introduction Displays are one of the most important features of any smartphone. The screen is the primary way we interact with our phones, so advancements in display technology can really enhance the user experience. Smartphone displays have come a long way in a relatively short period of time, evolving from basic LCD screens to stunning OLED displays with incredibly high resolutions and refresh rates. In recent years we've seen some major innovations in smartphone display tech, like folding screens, in-display fingerprint sensors, and front-facing cameras tucked completely under the display. Smartphone manufacturers are pushing the boundaries of what's possible with display hardware and software, bringing us screens that are more responsive, immersive, and visually impressive. In this blog post, we'll break down some of the most exciting developments happening in the world of smartphone displays. We'll explain the different types of displays, Whether you're an earl...

Blockchain technology has become one of the most disruptive and transformative innovations of our time. In its relatively short existence, blockchain has challenged conventional thinking and practices across industries, from finance and banking to supply chain management and voting. But what exactly is blockchain and How Does Blockchain Work? What is blockchain? Blockchain is a technology that enables computers to maintain secure and fair lists, known as ledgers, using advanced mathematical techniques and specialized codes like hashes and digital signatures. It facilitates collaboration among multiple computers to store and manage information. Blockchain is used for significant purposes like managing money, conducting elections, and safeguarding confidential information. Blockchain functions as a distributed and democratic ledger system that ensures the integrity of stored data. How Does Blockchain Work? Let's pretend a classroom has a show-and-tell ledger. Normally, the teacher i...

Introduction Virtual reality (VR) an obscure concept found only in research labs, has transformed from early experiments in the 1960s to a disruptive technology adopted by millions today. VR is now a mainstream phenomenon used in diverse applications across gaming, entertainment, design, healthcare, education, and more. So what exactly is virtual reality? It is the computer-generated simulation of a three-dimensional environment that can interact in a seemingly real way by a person using electronic equipment, usually including a helmet-like head-mounted display (HMD) with a screen, earphones, and sometimes gloves equipped with sensors. The VR system tracks the user's head motions and adjusts the visuals on the HMD accordingly, giving the sensation of being immersed in the virtual environment. While the most popular applications of consumer VR today are in gaming and entertainment, this emerging technology has enabled breakthroughs across many industries. VR allows users to experie...

Over the past decade, smartphones have become an indispensable part of our daily lives. With their ever-growing capabilities and utility, smartphones are now packed with a variety of advanced hardware components under the hood. In this blog post, we take an in-depth look at the key hardware elements that make up a modern smartphone. Display The display is arguably the most important component of a smartphone, as it is the primary interface we interact with continuously. There are two main types of displays used in smartphones today: 1.LCD (Liquid Crystal Display) LCD displays work by modulating the intensity of light passing through liquid crystals. They require a backlight for illumination.  Pros of LCD: - Mature technology that is inexpensive to manufacture - Provides good image quality - Available in a wide range of sizes 2.OLED (Organic Light Emitting Diode) OLED displays work by passing electricity through thin organic material that emits light. They do not require a backligh...

The Internet of Things (IoT) is transforming the way we live, work, travel, and conduct business. As more and more objects, devices, and places become interconnected, our world is increasingly becoming an intelligent, responsive, and automated environment. What is Internet of Things  what exactly is the Internet of Things? The IoT refers to the network of physical objects embedded with sensors, processing ability, software, and connectivity that enables these objects to collect and exchange data with minimal human intervention. Simply put, the IoT allows physical things or “things” to be connected to the internet and to each other. These connected things have the ability to sense, process data, and communicate. The IoT ecosystem comprises of several components: - Physical devices and objects - The “things” in the Internet of Things can include a wide variety of physical objects such as smart home appliances, wearable fitness trackers, industrial machines, connected cars, medical...

Introduction  Artificial intelligence (AI) is totally changing up our whole society, in ways we couldn't even dream of, like, ten years back. It's not just about work or life anymore – AI-powered smart machines are teaming up with us humans, making us even better at things and supercharging how stuff gets done in every single industry out there. And get this, AI's still growing and changing, but it's already out there shaking up everything from making stuff and farming to keeping us healthy, moving around, and way more! In the blog post, we'll explore 10 instances of artificial intelligence that are in action today. These examples show the huge potential of AI and machine learning across different areas. From improving medical diagnoses to streamlining supply chains, they illustrate how AI boosts human abilities and automates tasks. While advancements in robotics and autonomous systems also getting hype. As you see, AI is not some far-off technology - it is here tod...
