When making electrical connections, one of the most critical aspects is soldering. Also, the soldering process is inevitable in joining almost all electronic components. But what exactly does this process entail? What are some of the key considerations during soldering? What are t

In electronic circuits, the unidirectional flow of electric current perspective is very significant. Also, the electronic component responsible for such a role is a normal diode. There’re thousands of diodes capable of delivering the  ‘One-Way’ Diode result.

A remote control tester is a standard device in our households. In truth, you use it to control many electronic appliances like your TV, air conditioner, cable box, etc. But what happens when the remote goes faulty, and you can’t control these devices anymore? That’s where a re

AMS1117 Pinout is a linear voltage regulator, often available as an SMD component or DCY package. The 3-pin device has variable/ adjustable and fixed voltages that serve voltage regulators accordingly. Besides that, it can operate a load that requires less than 1A. Today’

Using a MOSFET transistor, we can control the voltage or current flow between the source and the drain. Also, there are different types of MOSFETs. The N-channel type Mosfet is one of these. The N-channel Mosfet is a metal oxide semiconductor field-effect transistor(FET). We often

LED Voltage indicator Source: Wikimedia Commons An LED voltage indicator is an essential tool you should consider if you plan to build measuring equipment with accurate results. However, creating a DIY LED voltage indicator or implementing it in your existing project

Are you looking for batteries for your project that can charge easy and fast? Then, consider getting an Ni-Cd battery. Also, the Ni-Cd battery packs are more tolerant and perform under harsh conditions. Further, the battery is more durable than lithium batteries or lead-acid ba

A voltage comparator is an electronic component that compares two currents or voltages, then determines which is greater at the output. Generally, the comparators are miniature voltmeters that have switches. There are a variety of comparators, such as LM311, LM393, etc., but we

Do you deal with microcomputers, PCBs, or programmable modules? Then, you need an IC component that works. And the QFN or quad micro lead frame package is one to consider. What is QFN? It means quad flat no-lead. We’ll go into details later in this article. So, why opt for Q

A study into the history of electronics will point out that transistors’ invention was crucial for humankind. Transistors are available to replace bulky, power-intensive, and low-efficiency vacuum tubes.  Currently, we use transistors either for amplification or switching

From concerts to annual functions of any educational institute, there is not a single event that completes without the mic. Formerly, people used cable microphones to amplify the voice. It converts the sound waves into electric signals and carries them through the cable. The recei

Are you an engineer or manufacturer who wants to understand the frequency of tracking time or stabilizing radio transmitters and receivers? If yes, you need to have a broad understanding of a crystal oscillator circuit with load capacitance. That way, you can build a project, like

We all agree that transistors have taken newer shapes and specifications since their invention. Talk about the BJT and MOSFET transistors. These are modifications that have well-improved technology over time. However, our attention is on the IRFZ44N MOSFET here. But, why this p

Whether you’re working on a rectifier circuit or powering your home, a center-tapped Transformers or center tap transformer is convenient.  Hence, we look at center-tapped transformers, their working principles, specifications, and where you can use them in detail. R

Have you ever used a walkie-talkie or an audio amplifier? Or are you into radio listening as a hobby, switching from one FM/AM band to the other? For example, some typical applications use the AM receiver circuit. Also, they are essential components of radio systems, in general.

Nowadays, microelectronic components are vital in circuits. Most are improved versions of the basic ones. Examples include resistors, capacitors, inductors, and transistors. The silicon-controlled rectifier (SCR) is the most widely used semiconductor device.  In no small w

When operating a radio or a musical instrument, you turn a button for volume controls. Also, if you’ve interacted with an audio amplifier, you might have noted the numerous buttons on the device. Note, potentiometers enable volume controls in all devices.  This article

One of the most popular cells available in power supplies or battery packs is the 18650 cell. The main reason it’s so popular is that it has specific characteristics that stand out. These are the current carrying capacity, storage life, operating temperature, safety, an

Generally, a step-down transformer or switch-mode power supply converts high AC mains voltage to a low AC voltage. Then, it furthers the conversion to a desirable low DC voltage.While it’s efficient, the process is costly and needs more space when designing or manufacturing
