A sampling of my favorite programming projects that I have worked on
My most popular iPhone app is Gravity!, which has over 27,000 downloads since it was first released in 2013, including educational downloads from school districts. It is a gravitational particle simulator featuring customizable planets, newtonian gravity, to-scale representations of solar system planets, and black holes. It is available on the App Store for free on iOS devices running iOS 7 or later.
The first iPhone app that I ever wrote was a simple game called Mazetron, which was released in 2010. The app includes GameCenter support for leaderboards. It is currently available on the App Store. I haven't updated it in a while, but I am working on a sequel.
One of my oldest iPhone apps, Spellcaster is a 2D platformer RPG. It features original artwork done by my friends and I and a fighting system based around using the touch screen to cast spells. It is an ambitious project that is far from completebut is available on the App Store in its early state at the moment.
Frances Grimaldo and I won the DocuSign Click API 1st place prize at CalHacks 2019 with our submission of Unlocc: a website which allows property owners to grant temporary access to visitors, with use cases such AirBnB or Escape Rooms in mind. The property owner registers a visitor phone number, some info about their property, and the access info for an August smart lock into the website. Then the visitor logs in with their phone number, and is presented with a DocuSign Click agreement that they must sign, that has been automatically generated from the info entered by the property owner. Once the document is signed, the visitor can control the August smart lock via the Unlocc website.
Nathan Pannell and I won the SendGrid prize at TreeHacks 2016 with our submission of Mail Trail: a game played through email and text messages. The game relies on a Flask server that uses the SendGrid and Twilio APIs to process incoming emails and texts and respond accordingly. The game is played entirely through email or text, with the user and the server replying to each other's correspondance.
Lafayette Historical Walking Tour
This app was my Eagle Scout project. I worked with the Lafayette Historical Society to gather information and historical images on locations around my hometown: Lafayette, California. The app uses GPS to detect when the user approaches a historical location and will automatically display text, audio, and images relevant to the current location.
I built this volumetric display with some of my friends at CalHacks 2015. The term "Volumetric Display" means a device that displays objects in three dimensions as opposed to two dimensions such as a traditional screen. The device consists of 42 LEDs spinning rapidly while controlled by an arduino and six shift registers. The arduino blinks the LEDs in a pattern to light up the right locations in 3D space at the right time in order to produce an image.
To build the glow scooter, my friends and I removed the cap from a cavity on the scooter, 3D printed a replacement with room for electronics, and inserted an arduino and a rechargable battery. Then we hot glued Neopixel LED strips to the underside of the scooter, and programmed the arduino to display pretty patterns as you ride around.
I wanted better lighting in my room, so I took a strip of multicolor LEDs, and set up an arduino to control them. Realizing I needed a way to change the pattern or turn the light off, I took a speaker from a scrap pile and experimented to see if I could use it as a makeshift microphone. The result was a huge success! I am continuing to improve on the clap lighting project. The next step will be controlling the lights over the internet.
