Nonlinear Wave Propagation in 1D Polycatenated Ring Chains
Chains of interlocked rings — chainmail, essentially — carry waves that behave nothing like those in classical granular crystals. Combining impact experiments, finite-element modeling, and discrete-particle simulations of gravity-pretensioned vertical...
How a Rattlesnake Rattle Makes Its Sound
A rattlesnake's rattle is a chain of about ten loosely interlocking keratin shells, shaken at tens of hertz. What turns that motion into the sound we hear? Working with a...
Wireless, Passive, Self-Stabilizing Drone
This report details the attempt at developing a passively controlled, wirelessly powered, and self stabilizing quadcopter system. We transfer power using a class E amplifier circuit, allowing the quadcopter to...
Smart Roller for Automatic Fiber Placement
Working with the amazing team at UBC Molecular Mechatronics lab, we developed a soft capacitive sensor array that can be wrapped on a smart roller for automatic fiber placement machines....
Raman Spectroscopy on Graphene
A brief discussion on the crystal structure of graphene and principles of Raman spectroscopy, followed by a literature review on recent experimental results exploring the Raman spectra of twisted bilayer...
Holographic Algorithms for Variational Time Evolution
Presentation slides for my undergraduate thesis defense. In this talk, I discuss the motivation, theory, algorithm, and preliminary results on developing holographic algorithms for variational time evolution simulation. Many concepts...
Michelson Interferometer
Presentation given to a high school audience about Michelson interferometers. Discussion and problems includes basic concepts in waves, interference, interferometer geometry, and its experimental significance leading to the discovery of...
Flexible Tactile Sensors Video
Video summarizing the flexible tactile sensors developed at the UBC Molecular Mechatronics Lab. Using capacitive sensing principles and different geometries, these sensors can measure pressure, shear, and proximity. They can...
Electronic Polarons and Bipolarons in Iron Based Superconductors
Public talk given at UBC Quantum Matter Institute discussing my summer research in condensed matter theory, supervised by professor Mona Berciu. I discuss the model of polaron and bipolarons, prove...
Engineering Physics Courses Review
Some of my PERSONAL opinions on courses I have taken at UBC. Most of the courses are part of my undergraduate degree in Engineering Physics.
Drone Regulations
A brief discussion and literature review on the role of drones in society, their benefits and harms, and how drone regulations play a role in society.
Radio Frequency Circuit Designs
Radio frequency circuit design course projects. Cadence designs of a low noise amplifier, a mixer, and a voltage controller oscillator.
A Tale of Two Black Holes
Presentation given to a high school audience about LIGO and a simple model of the collision of two black holes. The energy released from the collision is estimated by calculating...
OpAmp Design and Simulation
Schematics and LTSpice simulation of a differential operational amplifier built from MOSFETs with some optimization on gain, bandwidth, and supply-independent biasing circuit.
The Magnetic Pendulum, A Classical Mechanics Analysis
I investigate the motion of a pendumlum swinging above three magnets using small angle approximation and Lagrangian mechanics. I also use python to simulate and graph some interesting 2D projections...
Can Collecting Robot
At home robot project to collect cans, driven by STM32 Blue Pill. Engineering classes gives us all sorts of advanced tools, but this project taught me it's equally fun and...
Alice Through the Looking Glass -- Parity Symmetry Experiment
Slides from a TedX style talk given on the experiment that broke parity symmetry, and how we can tell the looking glass universe from our own.
Can Collecting Robot -- Design Proposal
Slides from our robot design proposal for the 2020 ENPH 253 can collecting robot competition. Draft CAD design and system level diagrams for circuitry were presented.
Illustrating Group Theory with Peg Solitaire
Slides from a TedX style talk given on how we can use group theory to analyze the Peg Solitaire game, unraveling one of the simplest unsolved mysteries of my childhood....
UBC RoboMaster Robotics Team
One of my greatest adventures in university: A group of robot enthusiasts dedicating their whole summer and beyond to one of the largest university robotics tournaments in the world.
