The Universal Appliance Standard (UAS) is an open-source framework for designing modular, customizable, and energy-efficient appliances. It combines virtual-first CAD design, advanced materials research, AI-assisted sourcing and manufacturing, standardized testing, local production, repairability, and upgradeable components to create appliances that can be built, improved, and maintained anywhere. https://roxanneardary.com/universal-appliance-standard/

AstraForge is an open-source mission operations stack for aerospace innovation, providing modular infrastructure for planning, simulating, monitoring, and operating rockets, spacecraft, satellites, and exploration systems. Built around telemetry intelligence, digital twins, ground station networks, spacecraft operations, and aerospace data interoperability, AstraForge enables transparent and collaborative development of the next generation of space technologies. https://roxanneardary.com/astraforge/

PredictaFlux is a modular, AGPL 3.0+ energy intelligence platform designed to transform triboelectric and micro-energy signals into structured, predictive, and optimizable data. It combines digital twin modeling, material physics simulation, and distributed mesh coordination to forecast energy generation, manage storage behavior, and optimize energy flow across connected devices. Built as an extensible system, PredictaFlux enables researchers and developers to model, simulate, and coordinate ambient energy systems through a unified, event-driven architecture. https://roxanneardary.com/predictaflux/

OrbitReasoning Core is an AGPL 3.0+ autonomous AI Network Operations Center designed for satellite, spacecraft, and aerial system management. It replaces traditional monitoring with simulation-first reasoning that computes outcomes before actions are taken. The system ingests real-time telemetry, builds orbital state graphs, runs predictive digital twin simulations, and produces governed, explainable decisions for anomaly response, collision avoidance, and constellation optimization across large-scale space networks. https://roxanneardary.com/orbitreasoning-core/

NeighborhoodGraph is an open-source civic intelligence platform that transforms housing, land, infrastructure, and community data into an interactive knowledge graph. It enables users to explore properties, ownership networks, neighborhood trends, and public infrastructure through AI-powered analysis and digital twin visualization. By connecting fragmented public records and geospatial data into a unified system, NeighborhoodGraph helps communities, researchers, and governments better understand how places change over time and how those changes impact people’s lives. https://roxanneardary.com/neighborhood-graph/
