PulseDrive is an open-source, AI-assisted driver safety system that verifies sobriety before vehicle startup and continuously monitors driver identity and attention during operation. It combines fuel-cell breath analysis, CO₂ and pressure-based breath validation, and edge AI vision systems using dual RGB/IR cameras for driver monitoring and liveness detection. The system runs on edge hardware (such as NVIDIA Jetson or Intel NPU devices) and integrates with vehicles through a safe, read-only CAN/OBD-II interface that only authorizes ignition when safety conditions are met. PulseDrive is designed with a strict separation between deterministic safety-critical logic and advisory AI modules, emphasizing privacy, modularity, and automotive-grade safety principles under an AGPL-3.0+ open-source license. https://roxanneardary.com/pulsedrive/

GreenMile is an open-source CO₂e calculator that measures and tracks travel-related emissions, with a strong focus on Scope 3 business travel. It provides tools for calculating, visualizing, and reducing carbon output across flights, trains, cars, and other transport modes, while supporting organizations with reporting, analytics, and sustainability insights under an AGPL-3.0+ license.

Das Projekt „Klimadashboard Sachsen” versucht den Fortschritt der Energie-, Verkehrs- und Landwirtschaftswende zu dokumentieren. Dazu werden Quellen aus den einzelnen Sektoren zusammengetragen und mittels moderner Webtechnologien anschaulich gemacht.
