Portfolio of
Jason Morales
Fourth Topic
Electromagnetism
Topic Summary
Electromagnetism introduces the study of how electric and magnetic fields interact, including the principles that govern electric charges, currents, and the production of magnetic fields, and how they are related through phenomena like electromagnetic waves.
Deals with wifi(Radio Waves)
NFC Card
Project Summary
I programmed an NFC card named "man" using Apple's Shortcuts app to automate my daily tasks. It sends a "Good morning" message to my girlfriend (or a special birthday message), opens my book, activates Do Not Disturb and Low Power Mode, and plays lofi music.

Project 2: RC Car(Fail)
Project Summary
Our RC car project explored the principles of AC and DC circuitry, leveraging a NodeMCU ESP8266 microcontroller to develop an affordable, WiFi-enabled robotic platform controlled via smartphone. The 2WD design used DC motors powered by 18650 batteries and controlled with an L298N motor driver, with circuits assembled on a mini breadboard to enable efficient prototyping and adjustments.
Challenges such as network connectivity and remote control functionality were addressed using logical problem-solving techniques, emphasizing the practical application of circuit theory and WiFi protocols. The collaborative effort involved iterative modeling of the car’s power distribution and motor control systems to reflect real-world performance accurately. Future work aims to optimize AC and DC circuit efficiency, explore a 4WD configuration for enhanced mobility, and integrate sensors for more advanced robotics applications, further deepening our understanding of IoT and electronic design.

I worked on the theory of how the circuit works while my team assembled and constructed the rest report
Although a fail, learned alot about how the circuit worked and learned how to 3d print by my peer
TopicSummary
DC and AC circuits introduce the concepts of direct current (DC), where current flows in one direction, and alternating current (AC), where the current periodically reverses direction, with each having different behaviors and applications in electrical systems.
Third Topic
Circuitry for movement of car
Project 3: RC Car(Success)
Had to rewrite a snippet of code to compensate for different wheel and use a soldered power adapter to connect the car and battery.

Forces and Fields
Topic Summary
Fields and forces introduce the concepts of electric and magnetic fields as regions influencing charges and currents, where electric fields exert forces on charges, and magnetic fields exert forces on moving charges or currents.
Second topic
Particle Model based on Space-Time Model
Structure for Semiconductor
Project 1: Particle Accelerator(fail)
Project Summary
This report highlights the application of electromagnetism in developing a Wi-Fi-controlled RC car, emphasizing wireless communication and IoT integration. Using principles like Faraday’s Law and Lenz’s Law, the car's motors and wireless systems were designed for efficient and precise control.
The transition from the Blynk IoT platform to a custom web server with the ESP8266 and ESP32 microcontrollers improved connectivity and performance. Key advancements included enhanced power regulation, refined motor control using L298N drivers, and robust structural stability. This project demonstrates the practical intersection of electromagnetism and Wi-Fi technology, showcasing its role in modern robotics and IoT systems.
Group Collaboration
We all agreed to work on own own cars. And incorporate all of them in the video and report
Topic Summary
Electric and Magnetic Properties of Matter
First Topic
Coulombs Law Problem
This is also an attempt at preparing for my interview 1.
The electric and magnetic properties of matter introduce how materials respond to electric and magnetic fields, including phenomena like polarization, magnetization, and the classification of materials as conductors, insulators, or ferromagnets.
Our project applied the principles of electric and magnetic properties of matter, forces, and fields to design a scaled-down particle accelerator, pivoting from an initial maglev train concept due to feasibility challenges. The design utilized solenoids to generate controlled magnetic pulses, propelling a magnetic sphere around a 3D-printed track, with circuits comprising transistors, resistors, and capacitors.
Project Summary
Group Collaboration
I was told to work on the theory
While we successfully constructed the physical components, creating a functional circuit posed difficulties due to limited experience and external constraints, such as time and shipping delays. Collaborative problem-solving and modeling helped us understand the interplay of forces and fields governed by Faraday’s Law, Lenz’s Law, and Ampere’s Law, even when full implementation proved elusive. Future improvements, including optimized circuitry, increased coil density, and higher-voltage power supplies, could enhance performance and scalability, deepening practical insights into electromagnetism and its applications.

The interviews were a unique way of "testing", my educator made me realized how lack luster my thoughts are in physics topics and my questions arent as thought provoking. This setback will be my sole focus to prepare me for any future interviews in my career.
