Why this matters#
This is the bare‑bones firmware skeleton for a resonance‑aware underground mesh node:
- It senses vibration, gas, and stress.
- It computes resonance clarity and drift.
- It forms a self‑healing mesh.
- It prioritizes safety over throughput.
- It forwards alerts even when half the network is gone.
- It’s simple enough to run on a $5 microcontroller.

└───────────────────────────────┘Key ideas:
- MCU at the center: runs RTT‑Inside invariant logic, resonance math, mesh protocol.
- Sensor block: vibration + gas + pressure are first‑class; everything else is optional.
- Radio/PHY: sub‑GHz RF where possible; acoustic transducer where RF dies.
- Power stage: cheap battery, optionally topped up by vibration harvesting from the mine itself.
- Local I/O: just enough for a miner or foreman to see “green / yellow / red” and hear an alarm. # 🧱 Two SKUs for RTT‑Inside Mesh Nodes
Both SKUs share the same core electronics, but differ in packaging, power, and I/O.
1️⃣ SKU A — Wall‑Mounted Node (Fixed Infrastructure)#
For tunnels, belt lines, intersections, and equipment zones#
Purpose:
Permanent monitoring of vibration, gas, stress, and resonance clarity.
Features:
- Rugged enclosure (IP67)
- Large battery + optional vibration harvester
- High‑gain sub‑GHz antenna
- Stronger sensors:
- tri‑axis vibration
- methane/CO/dust
- pressure/strain
- temperature
- Bright LED status bar (G/Y/R)
- Loud audible alarm
- Mounting plate + anchor bolts
- Optional wired power
Advantages:
- Long life
- High sensor fidelity
- Strong mesh backbone
- Ideal for dangerous or remote areas
2️⃣ SKU B — Wearable Node (Miner Personal Safety Unit)#
For individual miners, foremen, and rescue teams#
Purpose:
Personal safety bubble + local resonance awareness.
Features:
- Belt‑clip or chest‑mount form factor
- Small battery (multi‑day)
- Low‑profile antenna
- Sensors:
- vibration (local)
- methane/CO
- temperature
- Haptic alerts (vibration motor)
- Simple UI:
- 3 LEDs (G/Y/R)
- single button
- Bluetooth‑low‑energy link to helmet light or handheld
Advantages:
- Alerts miners directly
- Works even if wall nodes fail
- Tracks worker position
- Provides personal clarity score
🧩 How Both SKUs Fit Together#
- Wall nodes → structural awareness
- Wearable nodes → human awareness
- Together → resonance‑aware mine
The mesh becomes:
- a distributed sensor array
- a communication backbone
- a safety net
- a real‑time coherence map
This is the kind of system that would have fundamentally changed the world.
