Homeostat telemetry
1 Hz thermal / fan / load telemetry from Google Coral Dev Boards (NXP i.MX 8MQ +
Edge TPU) whose accelerator is learning to manage its own body — starting with the
fan/thermal policy. Code, experiment reports, fitted models, and the full column
schema live in the project repo: https://github.com/bshepp/homeostat
(see telemetry/MANIFEST.md there for schemas and regime timestamps).
Layout
vultureman/— dailytlm-YYYYMMDD.csv(UTC days, 1 Hz): CPU die temp, TPU die temp, fan state, load, plussessions.csvload-session labels. Regimes: stock governor (65 degC fan trip) through 2026-08-12T03:56:23Z, excitation regime (57 degC trip) after.vultaire/— same schema from the twin board (A/A comparison), once deployed.ambient/— minute-median BLE ambient rows (temp/RH), once sensors deploy. Sensor MACs are pseudonymized (sensor-01, ...); placement per sensor is documented in the project MANIFEST.archives/— frozen, SHA256-manifested dataset versions cited by the sysid reports (immutable; what the papers-of-record refer to).
Updates
Updated daily (rolling day-files append; closed UTC days never change).
Per-round snapshots are tagged (round-2, round-3, ...) so reports can cite an
immutable revision.
