In Electrical and Computer Engineering (ECE) curricula, the hands-on laboratory experience is often hindered by issues like limited physical resources and scheduling conflicts; to address these challenges, REDTAIL implements a multi-module approach, which is centralized in the REDTAIL Simulation Repository (RSR). This paper focuses on the RSR, a scalable, open-source centralized hub designed to provide instructors with a dedicated access and deployment point offering lesson plans, exercises, and various other tools. It features a robust web interface that delivers a clear educational experience, connecting the back-end of simulations, and through integration with \LabsLand, seamlessly incorporates access to remote laboratories. Future work will focus on cultivating an active community of educators within the RSR, enabling them to share and customize educational materials, as well as integrating an AI assistant to provide real-time support and facilitate automated lesson customization and scaffolding. The RSR is thus a valuable step toward solving major issues limiting ECE curricula, empowering instructors, and promoting more efficient learning outcomes.
