What is PCB and how does it work?

 A Printed Circuit Board (PCB) is a fundamental component in electronic devices, providing the physical structure to mount and connect electronic components. The process of working with a PCB involves designing, fabricating, assembling, and testing. Below is a simplified guide on how to work with a PCB: 1. Designing a PCB PCB design is the first and crucial step. It involves creating a blueprint of the electrical circuit that will be etched onto the board. Choose PCB Design Software : Common tools include KiCad , Eagle , Altium Designer , or EasyEDA . Schematic Diagram : Create a schematic that shows how components are connected (e.g., resistors, capacitors, ICs). Component Placement : In the PCB design software, place components on the board. The design should consider the physical size and pin connections of the components. Routing : This is the process of connecting the components via traces (the electrical pathways). Ensure proper routing to minimize interference and avoid s...

How Manual Car Transmission System Works | What is transmission | Manual transmission | Automotive | Technological Innovation

  Manual Car Transmission System.      Manual car transmission, also known as a manual gearbox or stick shift, is a type of transmission system that allows the driver to manually select and change gears in the vehicle. It is commonly found in older cars and some sports cars but has been gradually replaced by automatic transmission in many modern vehicles. 1. Components :  These components work together to enable gear selection, transfer power from the engine to the wheels, and controls the movement of the vehicle. Gear Shift Lever :  The gear shift lever, also known as the gear stick or shifter, is the control interface used by the driver to manually select different gears. It is typically located in the center console between the front seats, and its position and movement determine the gear the transmission is in. Clutch Pedal :  The clutch pedal is located to the left of the brake pedal (in left-hand drive vehicles) and is used by driver to engage o...

Story of the wheel | Technology Facts

Story of the wheel The wheel has been an essential part of human life from the very early years of human civilization. The wheel can be best described as a circular object that rotates on an axil bearing. The earliest wheel were known to be wooden disks with a hole in the middle for the axle. the word wheel first came from an old English word. in Sanskrit, the wheel is called chakra to mean round or circle. It is believed that the wheel first originated around 3500BC in Mesopotamia (Part of modern - day Iraq) where it was used for chariots. some argue that it was invented by the Mesopotamians, the Northern Caucasus and central Europeans. Therefore, the issue of the wheel originated in still remains a mystery. The next step in the evolution of the wheel was made by the Egyptians 1500 years later in 2000 BC when they used spokes in their wheels and proudly used them in their chariots while the Greeks have the honour of introducing the cross bar or the H- type wheel. The other significant...
