Score: 7.3/10 (Innovation: 7, Technical: 8, Documentation: 8, Utility: 6)

Heard is an offline LoRa mesh system for hiking group safety, using ESP32 devices with GPS and e-ink displays to track positions and detect route deviations without cellular coverage. Its innovative combination of multi-hop relaying, firmware-in-the-loop simulation with terrain-aware radio modeling, and practical focus on group coordination over rescue-only devices makes it a compelling research prototype.

Target audience: outdoor enthusiasts, embedded developers, safety engineers
