Welcome to the world of Amateur Radio (often called Ham Radio). This is a hobby that blends technology, geography, community, and public service. Whether you want to talk

One of my viewers mentioned that he prefers a sleeve dipole constructed from RG316 coax in a flat top configuration. Though it is end fed, it has a

I came across IRLB4132, an N-channel MOSFET in my UPS. That was a 600VA, 300W UPS which I had used for my desktop computer. I no longer have a desktop and

Here I am checking the output of 7812 regulator IC after connecting two 9V batteries in series to the input. After that the output is being used to

The popular 7812 regulator IC is a three terminal positive voltage regulator IC which provides a stable output. While 7805 IC provides a steady 5V DC output, 7812

Insulated Gate Bipolar Transistor (IGBT) is a semiconductor device that acts as a high-efficiency electronic switch for high-power applications. It combines the fast switching of a Metal-Oxide-Semiconductor Field-Effect

The choice between an inverted V and a horizontal dipole depends on your needs, as both are effective but have different installation and performance characteristics. An inverted V

Battery Management System (BMS) is a circuit that monitors, controls and protects rechargeable batteries. Aim is to ensure safety, efficiency and longevity of the battery. It monitors voltage,

We will go through the basics of Raspberry Pi Pico and see how it can be used to control a NEMA 17 stepper motor.

Simple initial steps in getting Arduino microcontrollers work for you. These can be tried out by anyone having an Arduino Nano.
