  • A CLI configurator for Raspberry Pi. Recipes describe what a Pi should be, from networks, boot options, packages, gems, repos etc. then PiMaker applies them, from flashing the card through to running setup over SSH. The tool I use for every Pi I build.
  • A real-time 3D visualizer and session manager for Claude Code. Lifecycle events stream over WebSocket into a Three.js scene where each session is a Bit; sessions are tmux-backed, so you can drive them from the browser as well as watch them.
  • A headless Game Boy test harness built on the SameBoy core. It runs a script of timed inputs against a ROM and asserts on what ends up on screen and in memory, so I can validate a curriculum's worth of exercises in CI instead of by hand.
  • A Gem for interacting waveshare PN532 HATs on the Raspberry Pi. Includes glue code for the C Library, reading / writing capability for cards, and an encoder to make storing information within the card easier.
  • A Gem for interacting with the waveshare line of e-paper displays on the Raspberry Pi. Includes front-end display components, a system to manage the display and side buttons intelligently based on content, and scripts to control the device remotely
  • Financial services app to build credit scores, where users can purchase Tradelines, and staff can monitor and approve the transactions. Built full stack, with features like mailers, secure uploaders, and multi-user support.
  • Portfolio site for noted composer Clair Marlo, with various app-enabled features to store and curate her project credits, and communicate with potential clients. Designed full-stack in ruby on rails.
  • A feature-rich ULID implementation for ruby, that simplifies creation and manipulation of ULIDs, and takes full advantage of UUID compatibility. Build in ruby, using Cucumber tests.
  • Diorama is a group of virtual spaces designed to beguile the user's sense of scale. Created with Unity and the HTC Vive, the piece was features at "Getting Real: VR and the Real World," a 2018 DMA show.
  • Realities is a virtual reality journey that deconstructs the concepts by which we make meaning. A collaboration with a Los Angeles based art studio, designed with Unity and the HTC Vive.
