Ambient Signal ObservatoryPublic RF and satellite observatory using SatNOGS, CelesTrak and NOAA data, with cache/failure isolation and bounded satellite decode tooling.
E22 / EWM Wireless Configuration Test HarnessRepeatable serial/radio test workflow for E22 and EWM modules covering local configuration reads, temperature profiles, OTA initiator behavior and wired recovery tests.
Reticulum / RNode Mesh PrototypeMulti-node Reticulum setup with RNode radio interfaces, LAN TCP transport and ESP32/LR1121 experiments for resilient local messaging.
Wi-Fi CSI Presence Sensing SystemESP32 CSI collector, server-side signal processing and live dashboard for room calibration, motion and presence experiments using Wi-Fi channel-state changes.
Wi-Fi CSI Presence Detection Fails First at Calibration, Drift, and SynchronizationCSI is extremely sensitive to the radio channel—which is why it can sense motion and why uncontrolled rooms, clocks, channels, furniture, fans, and hardware differences can swamp a naive detector.
