Introduction In my early projects working with DC motors, I had to choose between brushless and brushed types depending on application needs. I noticed that brushless motors, also called BLDC, use electronic control instead of mechanical commutation, making them ideal where precise position and speed are needed. Brushed motors, with their brushes and coils, are […]
What is a Thermopile? A thermopile is a device designed to convert thermal energy into electrical energy. It works based on the principle of the thermoelectric effect, where thermocouples made of dissimilar metals are exposed to a temperature difference. These thermocouples are usually connected in series or parallel to form a pile, which helps in
Introduction From my years working with electrical panels, I’ve seen many breaker issues that people overlook until faults start to show. The most common signs include damage from overloading or general wear and tear that can fail the functioning of your circuit. Knowing how to spot a faulty breaker early is necessary to protect your
Introduction When working on your electrical projects, there’s always one essential product I reach for: dielectric grease. I discovered it in a university lab. There, it was used on spark plug connectors, light bulbs, and circuit terminals. It helped prevent corrosion, much like wax does, by acting as a reliable protectant. Though it’s not a
Introduction As an electrician and long-time enthusiast of electronics, I’ve often come across the frustration of devices not working—only to find that an open circuit was the real issue. When the flow of current is disrupted due to a broken connection, faulty component, or loose wiring, lights stop turning on and functionality is lost. By
Introduction During my early days working with digital systems, I often came across devices that needed a steady signal. One such vital electronic component is the local oscillator, a simple yet powerful tool that converts DC supply into an oscillating AC wave. It plays a critical role in generating frequency-based outputs that are essential for
What is Linear Motion? Linear motion, also known as rectilinear motion, refers to the movement of an object along a straight line, where the position of the object changes over time (t). It can be broken down into two types: uniform linear motion, where the object moves at a constant velocity with zero acceleration, and

What is a Multilayer PCB? A multilayer PCB is different from a standard printed circuit because it uses more than two layers of copper. At least a minimum of three layers of foil, core, and materials are sandwiched together with prepreg (PP) or adhesive, forming strong boards. The multilayer boards are linked through vias, NC
The growing trend of digitalization, wireless connectivity, and automation has boosted the market for electronics manufacturing, with daily production across the globe. Technology is constantly evolving, pushing for feature-rich devices that are smaller and faster. These devices rely on tiny components mounted on printed circuit boards (PCBs) to operate according to their functions. Components are

What is Flex PCB? A flexible board like FPC or FPCB is designed with printed circuits and components that can be bent, folded, or even twisted without losing stability. Built on polyimide film and other substrates, the material ensures thermal stability and high Flexibility, making it reliable for automotive, medical, consumer, and wearables devices. Its
