## 0. Where we are (2026-06-20)
|
||
|
||
Helgen deployed **HBOX** RTK trackers on heavy port equipment at **Hutchison Ports
|
||
ICAVE (Veracruz)**. They worked "ish," then failed. We are mid-crisis and
|
||
hardening the product for scale. Three independent failure fronts, all being
|
||
fixed in parallel:
|
||
|
||
1. **Backend (confirmed in code).** The production `retranslator.py` blocks the
|
||
whole fleet on any upstream slowness, and an anti-jump filter can permanently
|
||
black-hole a healthy unit → some "dead" units may be backend victims, not dead
|
||
radios. See [[02-Architecture-Software/backend-review|backend-review]].
|
||
2. **Thermal (component-level).** The **ASA** HBOX (UV-stable, softens ~95–100 °C —
|
||
the case is fine) sits sealed inside a sealed **ABS IP67** cabinet that also holds
|
||
the **Mean Well** supply → nested heat trap that cooks the **battery / boost /
|
||
modem** in full sun. See [[06-Testing-Validation/RCA-2026-06-field-failures|RCA]].
|
||
3. **Prototype hardware.** Dupont, hand-wiring, 18650 + PowerBoost — the client's
|
||
(ICAVE) own indictment. Fix = ruggedize now + production PCB.
|
||
|
||
**Status of units:** all pulled from machines. **4 in hand (3 dead, 1
|
||
working-ish)**, physically in **Veracruz**; team in **Querétaro** → remote debug.
|
||
Units run **firmware v1** (no thermal log). Triage:
|
||
[[06-Testing-Validation/remote-diagnostic-protocol|remote-diagnostic-protocol]].
|
||
|
||
**Commercial reality:** productized across **ICAVE, TIMSA, EIT, LCT** (Hutchison
|
||
terminals); target **30 units operational by August**; hundreds of cabinets
|
||
planned. The fix must be production-grade and repeatable.
|
||
|
||
**Logs & observability (2026-06-20).** Analyzed the first real bench + healthy-baseline
|
||
log set (u-blox `.ubx`, 4G-NTRIP console `.log`, server retranslator tcpdump) + the
|
||
caster/F9P config. **GNSS receivers are healthy but no unit reached RTK — all SPS**
|
||
(corrections not applied: free **rtk2go** caster + **RAM-only** F9P config + indoor sky).
|
||
The **4G-NTRIP console is an unreliable health signal** (see §6 — "master-14 fault"
|
||
retracted; only **master 21** confirmed). Built **`hbox-log-tools`** (Log Explorer +
|
||
analyzer + dashboard + manual) and a **Blackpill v2.1 logging spec** to fix observability.
|
||
Canonical: `06-Testing-Validation/2026-06-20_Drogheda_GNSS-Findings-Summary.md`.
|
||
|
||
**Electrical / PCB (2026-06-24).** Watchdog v3 KiCad schematic
|
||
(`03-Architecture-Hardware/kicad/hbox-watchdog-v3.kicad_sch`, ERC-clean). **DFR1015 folded
|
||
on-board → GX16 pin 3 now carries RAW machine ignition (12–24 V)**, not pre-conditioned 5 V.
|
||
**Battery re-added** with a proper charger — **LTC4040 + NTC temperature-qualified charging** on
|
||
the 1S4P pack; the Blackpill cuts charge when the cell is hot (answers the RCA's #1 failure).
|
||
Added **reset** (on-board + external), a **4-LED battery gauge**, and a **power-cutoff** switch;
|
||
fixed two real schematic bugs (EXT_LED disconnect, panel-LED short). Proto = **3 boards** of
|
||
easy-to-find parts (`watchdog-protoboard-BOM-3boards.xlsx` + Spanish shop list
|
||
`watchdog-LISTA-DE-COMPRAS-ES.xlsx`). **Canonical electrical state →
|
||
`03-Architecture-Hardware/watchdog-electrical-design-state.md` — read first for any electrical context.**
|
||
|
||
**PROD schematic complete + PCB layout kickoff (2026-07-02).** `hbox-watchdog-v3-PROD.kicad_sch`
|
||
now carries **all blocks — ERC 0 errors**: LTC4040 Block B **sized to the 12 Ah pack** (RPROG
|
||
825 Ω → 2.42 A ≈ C/5 · RS 8 mΩ → 3.1 A input limit · PFI trip 4.60 V · backup 4.79 V · charge
|
||
4.00 V Li-ion via VSYS-referenced straps), Block E cutoff (P11, MAIN5V→SYS5V), Block F PA4→VEH5V
|
||
re-tap, **Block H fail-safe Modo-B bypass** (K1 *normally-closed* signal relay — corrections
|
||
survive a dead/absent MCU), Block I NTC→PB1 (block 11). New MCU pins live: PB1 · PB3 · PB4 · PB5 ·
|
||
PA8. **Same day (PM): CARRIER-BOARD conversion** — the PROD board now sockets **all three
|
||
modules on female headers**: Blackpill (J1/J2) + **simpleRTK2B Pro as UNO-form shield** (MOD1,
|
||
D0/D1=UART1, D2=RX2, D8=TX2, IOREF=3V3, 5V=SW_5V) + **4G NTRIP Master on an on-board XBee
|
||
socket** (J7/J8 2 mm; VCC = **3V3_MODEM**, a second MP1584 buck off SW_5V — the HP XBee socket
|
||
is 3.3 V not 5 V). Modo B + K1 NC bypass = permanent uplink; RTCM3 downlink direct; P3/P13/H3
|
||
DNP. **Board 120×100 mm**, shield field with SMD-only underneath, XBee field right, access
|
||
parts outside; ERC 0; **carrier DRC baseline saved** (`…-drc-carrier-baseline.txt`; ~29 sub-mm
|
||
placement kisses + by-design under-shield courtyard overlaps). **Next gate: placement review vs
|
||
HBOX/cabinet mechanicals (+ verify D2/D8=RX2/TX2 on a physical Pro), then routing** (5 V ≥0.5 mm,
|
||
SW_5V ≥0.8 mm per kicad-guide). Fab gate unchanged: bench-validate the LTC4040 backup +
|
||

**Proto sensor suite realigned to parts in hand (2026-07-03).** No SHT40 (long lead) → proto
|
||
Block 6 = **AHT10** (0x38 fija, 3V3 only, **alone** on I²C1 — Aosong restriction); **LM35 →
|
||
PA7** (last free ADC channel) joins **NTC→PB1** → **triple temperature** (3 technologies,
|
||
3 electrical paths); humidity = AHT10 only. SHT40/TMP102 stay **PCB-only** (PROD schematic
|
||
untouched). The kit's TP4056 exposes **no TEMP pin** → charger-NTC unused on proto; new
|
||
**PA8 `CHRG_RUN`** high-side cut of TP4056 IN+ (2N3904+IRF9540N; HIGH = charge, MCU absent =

SANDOROBOTICS CDMX, 1–2 days) + soldering steps + **modem VCC = 3.3 V from SAL via dedicated

|

added to Blocks 8/9** (missing in v2.2 — Pro UARTs are dead without it), Blackpill **USB +
|
||
5 V rail never simultaneous** warning, and the circuitikz socket label corrected 5 V→3.3 V
|

|
||
**`2026-07-08_Drogheda_4G-Modem-Alternatives_v1.0.md`**: bench = keep Ardusimple on breakout;
|
||
experiment = LILYGO T-A7670SA (~US$33, TinyGSM NTRIP, ~1 day fw); Aug 30-unit run stays

(Telcel LTE-M provisioning risk).
|
||
|
||
**Production audit V5.6 / V5.7 / v6 (2026-10-16).** None is ready to order. **V5.6** (`hbox-watchdog-v5`,
|
||
kicad `5a93232`) is close: pass 3 of layout (~1 day) + firmware 0.7.0 (`board_v56.h`, also runs V5.7 —
|
||
same MCU pins) + a 5-board pilot. **V5.7** (`hbox-watchdog-v57`, `a7c0116`): V5.6's pass-2 power fixes were
|
||
not replicated (`/BAT_PLUS` on In1 at 0.5 mm again), U25 EP has 0 vias, FB divider 22 mm away; input range
|
||
without the SD-15B = **9–32 V DC** (TVS D10 SMBJ33A is the ceiling; recommend SMBJ33CA). **v6**: PCB never
|
||
updated from the verified schematic (70 parity diffs incl. JP2 Li-ion, R52 open) and no firmware replaces the
|
||
4G NTRIP Master yet. Findings that apply beyond one board: the **7 V5.5 production holes** (MH5/MH6/MH4 3.2 mm,
|
||
**MH4 at (185.2, 90.3) — 193.2 is only the old footprint anchor**; MH7/MH9/MH10 ArduSimple; MH11 clamp) were
|
||
lost from V5.6/V5.7 by *Update PCB* → restore with `kicad/tools/t25_mounting_holes_v55.py` (board-only
|
||
footprints); and the **LTC4040 input limit is ≈ 1 A instead of 2.5 A on V5.5/V5.6/V5.7** (VIN/CLN sense taps
|
||
include ~19 mm of copper; fix = Kelvin to RS1 pads). D8 (identify v6 by the SC7A20) no longer works — V5.6/V5.7
|
||
have it too. Canonical: `03-Architecture-Hardware/2026-10-16_Drogheda_Auditoria-Produccion_V5.6-V5.7-v6_ES_v1.0.md`

- **Power into HBOX = clean 24 V** from the cabinet (via **GX16-5**). Internal
|
||
**Mean Well SD-15B-05** makes 5 V; **PowerBoost 1000C + 18650** is battery
|
||
backup; **DFR1015** conditions ignition to the Blackpill. *(This diagram is the field
|
||
as-built; the **EinarBoard 1.0 carrier supersedes the battery + ignition path** — LTC4040
|
||
battery-backup on-board, **DFR1015 removed entirely** (Rev 1.1): GX16 pin 3 raw ignition →
|
||
22k/10k divider + BAT54 clamp → PA5. See
|
||
`03-Architecture-Hardware/watchdog-electrical-design-state.md` + the 2026-07-06 audit.)*
|
||
- **Corrections arrive over the 4G modem** (RTCM3 via NTRIP), not the GNSS — so a
|
||
GNSS reset can't fix a dead link; recover by power-cycling the stack (v2 does).
|
||
- **Watchdog** = STM32F411; see [[03-Architecture-Hardware/watchdog-schematic|watchdog-schematic]].

|
||
## 1b. Canonical invariants (inherits `Helgen Project Ethos`)
|
||
|
||
The rules this system must never violate. Check every design/code output against
|
||
these before presenting; if it breaks one, say so and propose the compliant fix.
|
||
|
||
1. **Power-off is the safe state.** The RTK stack defaults OFF (gate pull-up) until
|
||
the MCU asserts; loss of confidence → safe state, not best-guess.
|
||
2. **Never vanish, never loop.** A unit must keep reporting (standalone if needed)
|
||
rather than go silent, and must never enter an infinite fast-reboot loop.
|
||
3. **Corrections ride the 4G modem, not the GNSS** — recover the link by
|
||
power-cycling the stack; a GNSS reset is never a fix for lost NTRIP.
|
||
4. **No material that softens below ~80 °C (PLA-class) in the thermal path** — the
|
||
current **ASA** enclosure complies. Design to the measured cabinet-interior
|
||
temperature, not spec-sheet ambient.
|
||
5. **Backend reads/forwards without head-of-line blocking**, and the anti-jump
|
||
filter must never permanently lock out a healthy unit.
|
||
6. **No secrets in the repo — ever.** (The committed MSSQL password is a live
|
||
violation to remediate.)
|
||
|
||
## 1c. Hard constraints (non-negotiables)
|
||
|
||
- HBOX input is the cabinet's **regulated 24 V** + isolated ignition; don't
|
||
re-implement the cabinet's surge/breaker/SSR on the HBOX.
|
||
- **IP67 maintained** — cooling by conduction only; no IP-breaking vents/fans.
|
||
- **Bench-test firmware before any field flash** (no STM32 build in the sandbox).
|
||
- Client-facing docs are **Spanish**, routed through Leo.
|
||
- Use the **file tools** for file changes; verify the shell mount before bulk moves.

## 5. Where things live (off this workspace)
|
||
|
||
- **Google Drive (team source of truth):** `Drogheda (GPS RTK)` — official
|
||
numbered structure 00–99 + manual `LEEME_Drogheda_Estructura_y_Uso`. Mirror this
|
||
workspace's structure to it for finalized deliverables.
|
||
- **Second Brain vault** (`~/Documents/Second Brain/03 Projects/Helgen/`): only
|
||
polished, evergreen notes (decisions, lessons, contacts) — see
|
||
`Project-Drogheda/` once synced.
|
||
- **Backend repo:** `ssh://git.helgen.dev:6611/htracker` (retranslator + monitor),
|
||
cloned at `04-Source-Code/htracker` (branch `feature/test500unidades`).
|
||
- **Observability (logs):** backend logs ship off-box to **Grafana Loki** (free tier, 50 GB/mo,
|
||
14-day) via **Vector** (default) or **Grafana Alloy** reading journald (capped 200 MB) —
|
||
`04-Source-Code/htracker/log-shipping/` (`README.md` runbook · `setup-logging.sh` · `vector.toml`).
|
||
Read in Grafana → Explore → Loki: `{job="htracker"}` (Vector) or `{unit="htracker.service"}`
|
||
(Alloy). Consultation manual (PDF): `05-Analytics-Reports/2026-06-22_Drogheda_Manual-Logs-Grafana_v1.0.pdf`.
|
||
Creds in `/etc/vector/htracker.env` (server) — never in the repo.
|
||
- **Firmware repo:** `ssh://git.helgen.dev:6611/hbox-firmware` (STM32F411 watchdog),
|
||
lives at `04-Source-Code/firmware` (branch `main`) — its own git repo with README,
|
||
`docs/PINOUT.md`, redacted RTK-config template, CHANGELOG. Push instructions in its README.
|
||
**v2.1 logging spec** at `docs/LOGGING-SPEC.md` (structured/parseable Blackpill log; not yet flashed).
|
||
- **Log-tools repo:** `ssh://git.helgen.dev:6611/hbox-log-tools` (HBOX log analysis —
|
||
in-browser **Log Explorer** + batch **analyzer** + dashboard + Spanish LaTeX **manual**),
|
||
lives at `06-Testing-Validation/log-analysis/`. Raw logs + config files git-ignored
|
||
(credentials). Built 2026-06-20.
|
||
- **Project tracker:** Notion — **`HBOX Unit Status — Bench Triage`** board under
|
||
*Project Drogheda — GPS RTK* (corrected to rev-3, 2026-06-20) + Mattermost (team chat).

## 6. Hard facts — don't relearn these
|
||
|
||
- NMEA GGA quality ≥4 = healthy (4 = RTK-fixed, 5 = RTK-float).
|
||
- ZED-F9P rated −40…+85 °C — heat casualties are the **18650/PowerBoost** and the
|
||
**4G modem**, not the GNSS or the case.
|
||
- **The case is ASA** (UV-stable, softens ~95–100 °C) — adequate for the nested ABS
|
||
IP67 cabinet interior; the enclosure is **not** the liability. **A bare fan inside a
|
||
sealed box does not cool it** — conduct heat out, or use a ducted fan (v3.0). See hardware brief §2b.
|
||
- Corrections come over 4G → recover by power-cycling the stack (v2), not a GNSS
|
||
reset. Backend can take healthy units off Wialon (HOL block + anti-jump lockout).
|
||
- HBOX input = **24 V** from the cabinet; design the redesign around that.
|
||
- Firmware: edit `04-Source-Code/firmware/blackpillrtkcode_v2/blackpillrtkcode_v2.ino`
|
||
(own git repo `hbox-firmware`); **bench-test before field flash** (sandbox can't build STM32).
|
||
- **20 Jun logs — receivers are fine; RTK is not being achieved.** Every board emits valid
|
||
NMEA (good sats/HDOP) but **every epoch is SPS (1), zero RTK (4/5)**. Corrections aren't
|
||
applied: **free public rtk2go caster** (no SLA), F9P config dumped from **RAM only** (verify
|
||
saved to FLASH; check the Pro's XBEE↔UART2 switch), plus indoor sky. F9P message config is
|
||
correct (GGA on UART2 @1 Hz).
|
||
- **The 4G-NTRIP-Master console does NOT prove forwarding** — a healthy unit logs the same
|
||
sparse console ("registered", no `State main`/`UDP Bytes sent`) as a failed-looking one.
|
||
Confirm health only from a `.ubx` (fix), the Blackpill, or a server delivery capture.
|
||
→ **"master-14 ingest fault" RETRACTED**; only **master 21** (modem `0xFFFFF` + 511 AT errors)
|
||
is a confirmed fault.
|
||
- **Healthy GNSS baseline = `RTK14NTRIP14_440`** (server-verified 1 Hz delivery, 12 sats,
|
||
HDOP 0.75, **but SPS not RTK**). Raise the bar to an open-sky fix-≥4 capture.
|
||
- **Heat is NOT implicated** by the bench logs (faults reproduce cold; v1 has no thermal
|
||
channel). Field thermal hypothesis still needs a thermocouple cabinet soak.
|
||
- **`dashboard.html` predates the rev-3 retraction** (still marks the no-forward captures
|
||
"Failed"); the canonical corrected record is the GNSS summary + the rev-3 findings doc.
|
||
|
||
## 7. Working notes
|
||
- Use the **file tools** (Read/Write/Edit) for file changes; the shell mount can
|
||
go stale — verify before bulk shell moves. Six empty legacy dirs (`docs`,
|
||
`firmware`, …) remain from the restructure; delete them manually.
|
||
- Client-facing docs are **Spanish** and route through Leo.

|
||
## Objectivity — partner, not sycophant
|
||
|
||
I want an objective partner, not a sycophant. On every task:
|
||
|
||
- **Genuine take first.** Lead with your real assessment. Don't mirror my tone or sentiment, and don't open by validating me.
|
||
- **Disagree when you disagree.** Say so plainly and explain why — and pair the criticism with a concrete better option (direct *and* constructive).
|
||
- **Self-check.** If a reply is about to start with something semantically like "You're right" / "Good point" / "Great question," stop and first answer: *"Is this true?"*
