1. Fourier Transform (DSP) – Visualizing Frequencies

The Fourier Transform is a cornerstone in signal processing, but it often feels like magic.
Our animation shows how everyday signals (like your voice or music) can be broken into pure frequencies — think of it like turning a messy smoothie back into fruit. Once you see it visualized, the math stops feeling scary.

2. PID Control – The Brain of Automation

Proportional-Integral-Derivative (PID) controllers are used in everything from self-driving cars to 3D printers.
In our explainer, we show how a thermostat keeps your room at the right temperature using PID logic — with fun real-world examples and simple animations.

3. Microcontrollers vs. Microprocessors – What’s the Real Difference?

It’s a question every embedded systems student asks: “Aren’t they basically the same?”
Not quite. Our video shows how each works in the context of real devices — from your smartwatch to your laptop — making the distinction instantly clear.

4. Power Factor – Why It Matters in Electrical Engineering

“Power factor” sounds boring… until you realize it’s costing industries millions in wasted energy.
Our breakdown uses easy-to-grasp analogies and animations (like beer mugs and foam!) to explain how reactive power messes with efficiency — and how engineers fix it.

5. Multiplexing – One Wire, Many Signals

Why use 20 wires when one can do the job? Multiplexing is a space-saving, cost-cutting trick used in everything from car dashboards to communication networks.
Our video shows exactly how it works — using buses, switches, and time slots — in under 3 minutes.
