Made a physical audio visualizer using ferrofluid suspended in water, a python script that used serial communication with an arduino, the fast fourier transform that creates an audio frequency spectrum, and the basic principle of Electromagnetism.

A 3D model was made to hold the ferrofluid, with a circle underneath it to fit a solenoid, which would create a magnetic field when current was passed through it. The ferrofluid would then move in response to the changing magnetic field, creating a visual representation of audio signal.

The Python script would read audio data using PyAudio, which would request and retrieve data from the user's stereo mixer. This data would provide the waveform of the audio signal coming from the music played in realtime, using the Fast Fourier Transform (FFT), a mathematical algorithm that converts a wave signal to a representation in the frequency domain, a frequency spectrum is made.

The Python script would detect when a kick drum hit occured (by detecting peaks in the lower frequency range), and send a signal to the Arduino via serial communication. The Arduino would take this signal and send a current through the solenoid, creating a magnetic field that would cause the ferrofluid to move in response to the audio signal.

Using only transistors and a power source, created an 8 bit adder circuit that adds and outputs binary numbers. Also created a video explaining all of the logic gates used in the circuit, and how they work together to create the adder.

Researched how to add binary numbers using logic gates, and how to put logic gates together in sequence to create more complex logic gates on a breadboard (XOR, NOR, NAND). Took those new logic gates and combined them to create an adder circuit that could add two bits together, outputting a sum and carry bit.

Put all of the logic gates together to stimulate the same logic as adding binary numbers, then made a video how it all works:
Watch the video here.

Here are the logic gate stimulations I made to create the adder circuit (all made by me using everycircuit.com):
XOR Gate | NAND Gate | NOR Gate | AND Gate | Bit Adder (with only logic gates)

Created this entire website from scratch using HTML, CSS, and Javascript by myself.

Brainstormed across multiple ideas, and stuck with a cardistry and legend of zelda theme, two things I adore. I recorded me doing cardistry, photoshopped elements to make them fit with the website theme.

(1900 Lines of code) Used HTML and CSS to create the structure and style of the website, ensuring a responsive design that works well on both desktop and not so much mobile devices (yet!). Implemented Javascript to add interactivity, such as dropdown menus, animations, transitions between each page, and dynamic content loading. Everything you see on this page was curated by me, except the music, otherwise all footage and icons are from me.

Learned how to use GIT bash, handle repos, generate SSH keys, and set up DNS records to host the website on a custom domain.

Collaborated with 4 people to create and program an end effector arm for a mock-ecommerce company that could pick and place a variety of different shaped objects.

Formed a 3D model of the arm using Autodesk Inventor, ensuring gears mesh together properly, and that the claw is able to grip objects of various shapes and sizes efficiently. Went through 5 prototypes before finalizing the design to ensure optimal performance. Originally, we made a claw that used a single servo to open and close, but found that it was not strong enough to grip certain objects. Thus, we redesigned the claw to obtain more surface area across the object it was grippping, hoping it would increase the friction and grip strength. This worked only to an extent, as the arm would come down at an angle, and this would make it hard for the claw to grip it straight up, so we redesigned the claw again to have a more angular approach when picking up objects. To add a final touch, we added a block at the ends to allow for pinching, this allows us to say our design is versatile, being able to pick up objects with different techniques if needed. I brainstormed and 3D modelled the last 2 designs and the final build. These iterations Showed me the importance of prototyping and testing designs before finalizing them, as small changes can have a big impact on performance. Also showed me the value of teamwork and collaboration, as we were able to bounce ideas off each other and come up with a better design together.

Prototypes in chronological order

Used Unity built-in physics system to stimulate realistic ball movement and collisions. Adjusted physics materials to achieve desired friction and bounciness for the balls and table. Programmed a menu screen, spin ball function, free-roam/fixed camera options, and faithful win/lose conditions to enhance user experience.

Used 3D models found online to design the environment and pool table. Found 3D Textures online to implement realistic materials for the table, balls, and cues. Used Unity Cloud to work with version control, allowing multiple people to work on the repo simultaneously without conflicts, and when there were conflicts, resolve them using merging.

Here are just some extra stuff that I have done that I can show.
