PTHSonde v1.4.1 — Manual polish + Inventory Tracker
Documentation update on top of v1.4.0 (Balloon Fill Calculator).
Manual
- Cover art — severe-weather backdrop (public-domain NOAA cumulonimbus), filled edge-to-edge; the hero sonde's sensor window is now transparent so the cloud shows behind the thermistor; logo balloon filled white; orange subtitle for contrast.
- Header — larger PTHSonde (left) and TracerLab (right) logos, now on every page except the title.
- Chapter 5 reorganised (balloon choice, fill table, and Fill Calculator in one section); flight-train diagram pinned in place; parachute drawn as a triangle.
- New appendix: Inventory & Stock Tracker — fillable sonde / balloon / lift-gas tables, one per page.
- Measurement spec table reconciled with the firmware — 3 s downlink (
TX_INTERVAL_MS = 3000), 1 Hz internal sampling, 5 s wind average; fixed stale quick-reference figures.
