Electronics

In the image below, you'll see what is referred to as the "battery terminals".

In the image below, you'll see where to connect the power source and the motor to the motor speed controller.

Before connecting wires in your project, you need to remove the plastic insulation from the ends so that the metal wire inside is exposed. This is called stripping the wire. You can do this with a wire stripper or with items you might already have at home.

Here, we broke down all the tools and knowledge needed to properly solder and desolder components via THT (Through-Hole Technology).

What You’ll Learn:

1. Tools & materials needed for drilling.

2. Step-by-step drilling technique.

3. How to keep yourself safe in the process.

Why Are Voltage Regulators Important?

1. Protect components from over-voltage or under-voltage.

2. Ensure system stability in power supply circuits.

3. Improve reliability and lifespan of electronic devices.

What is a Capacitor?

A capacitor is a passive electronic component that stores electrical energy in an electric field. Think of it like a small rechargeable battery, but with some key differences — it charges and discharges much faster, and doesn't store energy for long.

You’ve probably seen a spinning fan with LED lights that forms text or images mid-air — like magic! But what’s really going on?

This cool effect is based on a concept called Persistence of Vision (POV). By spinning an LED strip fast and changing the lights at the right moment, our brain gets tricked into seeing a complete image — even though it’s really just one line of lights!

If you don’t rotate an object around its Center of Mass, you introduce instability, vibrations, extra stress, and sometimes complete system failure.
