Open Arsenal provides open, self-hosted software specifications designed for deployment across private and public networks. Built for portability, interoperability, and transparency, each specification gives organizations the freedom to implement and customize solutions without vendor lock-in while remaining free to use under the AGPL-3.0+ license with required attribution. Specification Branding Licenses available upon request. https://roxanneardary.com/open-source-projects/

Vendor-Independent, Fully Verified, Open Source VHDL Common Library

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/

Circulis Aqua is an AGPL 3.0+ modular infrastructure design system for desalination, water purification, reuse, and geospatial distribution. It uses AI-assisted configuration to design scalable, plug-in water systems that range from residential units to municipal and regional grids. Built on a graph-based water flow model, it enables local-first optimization, closed-loop water reuse, and intelligent routing to ensure no water is wasted across interconnected infrastructure networks. https://roxanneardary.com/circulis-aqua/

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.

FluxGrid Infrastructure is an open-source system for wireless EV charging that turns parking spaces into intelligent energy platforms. Vehicles simply align over an inductive ground pad and charge automatically without cables, while integrated thermal control maintains efficiency in all weather conditions. The system combines hardware, embedded firmware, and grid-level software to manage power delivery, safety, and load balancing in real time.

Beyond charging, FluxGrid is designed as a full infrastructure layer for autonomous mobility. It includes safety intelligence for environmental monitoring and fault prevention, grid optimization for energy distribution, and vehicle-to-grid capability for energy sharing. https://roxanneardary.com/fluxgridinfrastructure/

CircuitPath is an open-source framework for advanced chiplet packaging and system integration, enabling modular AI and HPC architectures through standardized chiplet models, interposer layouts, and simulation-driven design. Built under AGPL-3.0+, it provides a fully extensible ecosystem for modeling bandwidth, thermal behavior, and data movement across multi-die systems, empowering contributors to shape the future of open chiplet-based computing. https://roxanneardary.com/circuitpath/
