This Python, Flask, and React front end allows the user to issue commands to an Arduino microcontroller over a serial interface. The device state is stored in an SQL database.

This project aims to simplify the testing program of chemical and electric propulsion systems. The user may configure sub-systems in a dependency tree format, making accidental activation less likely. This also makes comparing different firings easier due to a common underlying control stack.

A delegate object handles control logic. This means the software can easily be reconfigured to operate different systems.

Puzzle Room is a Swift-UI-based iOS application that presents ciphers the user must solve. The application is presented in a vintage and retro color scheme with a pixel-art background.

Users are given a letter count to help them solve the code and can also ask for hints. This project grew out of one of my student's enthusiasm for these puzzles.

The story was written by my talented friend Tara Siddall. The Git repository also includes a Mac application called Puzzle Builder. This is a handy support application for generating JSON-formatted puzzles from raw text.

An Arduino project for reading commands from the serial interface and reliably activating and deactivating a series of MOSFET switches. With this project, reliability was vital, and the code implements a finite state machine to ensure that its behavior is well-defined.

A SwiftUI app for measuring, logging, and exporting measurements of magnetic fields.

Our engineering team needed this app to validate the assembly of pulsar's products quickly. The app uses the Core Motion framework to access the magnetometer, where readings can be nullified to remove the device's magnetic field. The app uses the iOS native share sheet for sharing data in the CSV format.

A sizeable physical game for a museum with a roughly 2x8m panel of circular targets which respond when hit by a ball. The targets light up to indicate the objective to the players.

I sketched out the game concept, constructed a hardware prototype, and subsequently brought the design to life in CAD.

The primary challenge was finding a suitable sensor technology that would give adequate sensitivity without letting strong hits trigger neighboring targets.

A secondary project involved designing a climbing ledge that could detect body weight, accommodate other LiDAR sensors, and remain safe for people to climb.

Integrating a remote team of six, I successfully delivered CAD illustrations, testing data, and installation guides for both installations.

This is a UIKit-based iPhone and iPad app for taking notes and marking them up using the Apple Pencil and text "stickers." The app is modeled on index cards students often use to prepare for exams. The cards are arranged in decks and can be added using the camera.
