Build for PIC microcontrollers with MPLAB XC compiler.

nixhost -- one host addressed as a path, the environments standing on it as projections of its own hardware, and the cross-host checks no per-host module can make.

Reverse engineering of the IKEA GETKÅL colour-changing LED string light: decoding its power-line data protocol (pulse-distance coding, 32-bit blocks, 12-bit colour, run-length zones) from oscilloscope captures.

Electronic and Software (Firmware / Host) for the OpenAstroTracker.

Nanocube 26 petaflops 3D silicon stacking architecture delivering supercomputer performance in desktop form factor using legacy fabrication nodes.

Express 5 + Socket.IO control service for an Arduino motion ride: streams AES-encrypted CSV motion telemetry over serial, syncs video across consoles, JWT auth, ride queue with emergency stop.

RoadCraft is an open-source AI motorcycle copilot system that combines helmet-based intelligence, real-time sensor fusion, and vehicle control integration to enhance rider safety without removing human control. It provides optional AI assistance for navigation, hazard detection, and emergency intervention, while supporting advanced features like V2X communication, stabilization systems, and edge-based processing. Built under the AGPL-3.0+ license, RoadCraft is designed for collaborative development of next-generation intelligent riding systems. https://roxanneardary.com/roadcraft/

LAVE (Low-Altitude Vehicle Experiment) is an open-source research platform exploring human-scale hover in the sub-meter regime using distributed electric thrust, real-time stabilization, and fully transparent hardware and software systems. Built for reproducibility and experimentation rather than productization, it focuses on measuring the unstable transition between ground contact and sustained flight, with all telemetry, failures, and design iterations openly shared as part of the research process. https://roxanneardary.com/lave/

KineticKind is an open-source SUV platform designed to make entering and exiting a vehicle safe, comfortable, and dignified through intelligent seat-assist technology. By combining rotating lift seats, accessibility-focused engineering, and a fully open development model, the project reimagines mobility around real human movement rather than mechanical constraints. Built under the AGPL-3.0+ license, KineticKind invites a global community to collaborate on creating more inclusive transportation for everyone. https://roxanneardary.com/kinetickind/
