This project is an advanced modular platform designed for students and electronics enthusiasts to explore the principles of electromagnetism, energy storage, and high-voltage circuits.

The core of the system is a Power Management Hub powered by two 18650 batteries in a parallel configuration (Vout=3.7V−4.2V), which serves as a base for various swappable experimental modules.
Features of the Control Hub:

Charging & Protection: Integrated USB-C charging module with a 5V USB-A output.

Instrumentation: Built-in digital voltmeter for real-time monitoring of battery discharge curves.

Auxiliary Outputs: Dedicated control buttons for a 5V laser diode (optical alignment) and a high-efficiency LED flashlight.

Magnetic Interface: Modules connect via a quick-swap 5x5x5mm neodymium magnet system, ensuring solid electrical and physical contact.

Experimental Modules Included:

High-Voltage Transformation Module: Designed to demonstrate the conversion of low-voltage DC to high-voltage AC/DC for plasma and dielectric breakdown studies.

Faraday Induction Demonstrator (EMP Coil): Using 1mm enameled copper wire, this module demonstrates the generation of localized electromagnetic fields and their interaction with passive electronic components.

Kinetic Accelerator (Coil-driven): A basic demonstration of how electrical energy stored in a field can be converted into kinetic motion through a solenoid.

Safety Warning & Disclaimer:

This project is for educational and research purposes only. It involves high-voltage circuits and strong magnetic fields.

Do not use near sensitive medical equipment (e.g., pacemakers).

Always handle high-voltage capacitors with caution.

Observe local regulations regarding radio frequency and electromagnetic emissions.
