3D Printed Home: 3D Printing is a cutting edge manufacturing and construction technology in the present era. This technology directly made a physical objects through a digital 3D model. Nowadays, it is  popularizing in the real estate or construction industry. In this article, I am going to share the very first use case of 3D printing for building a house in India.  Image Credit: tvasta Whats is 3D Printing 3D printing, also known as additive manufacturing, is a manufacturing process that creates three-dimensional objects by layering material upon material, following a digital 3D model or design.   This process offers several advantages, including the ability to create complex shapes, customize designs easily, reduce waste, and potentially manufacture objects more efficiently than traditional methods.  Various materials, such as plastics, metals, ceramics, and even biological substances, can be used in 3D printing, depending on the specific technology and applicati...

I have YouTube channel as well, for my channel I decided to make showpiece containing the name of channel. I wanted to place that showpiece on my table while recording the video for my channel. Hence, I came up with an idea to use 3D printing, laser engraving and some electronics items to make this showpiece. In this article, I am explaining the complete fabrication process for making that showpiece.  Part and Components used In this project, following components has been used: PLA Filament (For 3D Printing) Acrylic sheet with engraved channel name LED Strip 5mm DC Jack 12V DC Power source  Glue to assemble the 3D printed parts Soldering iron Computer to design the housing/casing The complete methodology to complete this project  contains - laser engraving, designing, 3D printing, assembling, LED strip installation. Now, I am going to explain each of these steps. Laser Engraving I choose a 150mmX30mmX5mm acrylic sheet strip to engrave the name of my website/ Youtube chan...

 Ultrasonic sensors have become increasingly popular in recent years, particularly in the field of IoT. They are used in a wide range of applications such as distance measurement, object detection, and obstacle avoidance. The ultrasonic sensor works by emitting high-frequency sound waves and then measuring the time it takes for the waves to bounce back. This information can then be used to calculate the distance between the sensor and the object. In this article, I will provide a complete guide on using an ultrasonic sensor with Arduino. I will discuss the principles behind ultrasonic sensors and provide a step-by-step guide on how to connect and use the ultrasonic sensor with Arduino. I will also provide a circuit diagram and complete code to help you get started. Principles Behind Ultrasonic Sensors HC-SR04 Ultrasonic sensors work by emitting high-frequency sound waves that are beyond the range of human hearing. These sound waves bounce off any object in their path an...

The Internet of Things (IoT) is the interconnection of devices, vehicles, buildings, and other items that can be embedded with electronics, software, sensors, and network connectivity to collect and exchange data. IoT has become an integral part of our daily lives, and with its rapid growth, there has been a surge in the development of affordable, easy-to-use, and versatile IoT devices. One such device is Arduino, an open-source hardware and software platform designed for building digital devices and interactive objects that can sense and control the physical world. In this comprehensive guide, we will explore everything you need to know about Arduino for IoT, from its basics to its advanced applications. Introduction to Arduino Arduino is an open-source electronics platform based on easy-to-use hardware and software. It is designed to be used by anyone, regardless of their technical expertise. Arduino can be used to create a wide range of interactive devices, from simple L...

Common Arduino Problems: If you're an Arduino enthusiast, you know how much fun it can be to tinker with the microcontroller and create exciting projects. But, like any other technology, Arduinos can sometimes run into problems. In this article, we'll explore some of the most common Arduino problems and provide practical solutions to help you get back to your project in no time.   Introduction Arduino is a popular open-source electronics platform that allows users to create interactive electronic projects. It's simple to use, cost-effective and has an active community of users and developers. However, like any other technology, it's prone to problems. In this article, we'll discuss some of the most common Arduino problems and provide solutions to help you troubleshoot them. Common Arduino Problems and Solutions Problem #1: The Arduino Won't Power On One of the most common Arduino problems is the board not powering on. This issue can be caused...

 If you are using fused deposition modeling (FDM) or fused filament fabrications (FFF) based 3D printers, then at some point in time, you must have faced or will face that the material being extruded upward direction or filament deflecting upward on extrusion. In this article, we will discuss the reasons and solutions for the material being extruded upward problem. Reason and Solutions for Filament Deflecting or Curling Upward Reason: Partial Blockage in Nozzle You may have a partial blockage if your filament curls up as it exits the nozzle. For instance, if there is a small amount of dirt on one side of the nozzle, the filament can still extrude, but it will curl. Solution Debris on the INSIDE of the nozzle, as opposed to bits on the OUTSIDE, is what causes the filament to deflect. You can clean the exterior as well as you like, but it won't really change much. However, deflection is brought on by a break in the flow. Yes, stuff on the exterior does enable additio...
