v6.9.5 — LUNA Lab INDI Edition: ADC + INDI Observatory Control

## AiBridgeMCP v6.9.5 — LUNA Lab INDI Edition 🔭🔬

> **AI that talks to the universe — and measures it.**

> LUNA now bridges Claude AI directly to professional astronomy software

> while gaining full analog sensing capability on ESP32-S3.

### 🆕 What's New in v6.9.5

#### `indi` module — Astronomy Device Control

Control any INDI-compatible telescope, camera, or focuser directly from Lua scripts.

This version includes **13 Lua functions** (connect, get/set properties, wait_state, etc.)

and **10 MCP tools** that allow Claude to operate your observatory via natural language.

#### `adc` module — Analog Input (ESP32-S3 ADC1)

Read real-world analog voltages directly from Lua scripts on the ESP32-S3.

| Function | Description |

|----------|-------------|

| `adc.atten(pin, db)` | Set measurement range: `0`=0–950mV / `1`=0–1250mV / `2`=0–1750mV / `3`=0–3100mV |

| `adc.read(pin)` | Raw 12-bit value (0–4095) |

| `adc.read_mv(pin)` | Calibrated millivolts (eFuse correction applied) |

| `adc.read_avg(pin, n)` | Average of n readings in mV — reduces noise (recommended n ≥ 16) |

**Supported pins:** GPIO1–10 (ESP32-S3 ADC1 only).

**⚠ ADC2 pins conflict with WiFi — use ADC1 only.**

---

#### `dac` module — Stub (ESP32-S3 Hardware Note)

The ESP32-S3 does not have a hardware DAC.

`dac.write()` and `dac.stop()` return a clear error message.

**Alternative:** Use `gpio.pwm()` with an external RC filter (10kΩ / 10μF) as a pseudo-DAC output.

---

### 💡 Verified on Hardware

All functions confirmed on **ESP32-S3**:

- `indi.*` — all 9 functions confirmed callable ✅

- `adc.read_mv(4)` — live voltage measurement stable ✅

- `gpio.pwm(38, 1000, 128)` — pseudo-DAC output confirmed ✅

- `json.encode / parse` — complex telescope coordinate handling verified ✅

### 🌉 From AI Bridge to AI Bridge & Platform

LUNA began as a bridge — connecting Claude AI to serial instruments via a simple MCP server.

With v6.9.5, that vision expands further.

By combining the **INDI protocol** (the open standard for astronomy)

with **Lua scripting** and **analog sensing**,

LUNA is evolving into an **AI-native physical computing platform**.

Claude can now not only communicate with devices

but **sense, measure, and autonomously control** an entire observatory

through natural conversation.

> **Serial bridge → WiFi control → Sensor fusion → AI-driven observatory.**

> One device. One platform. Driven by AI.

### 📦 How to Use

1. Flash `AiBridgeMCP_v6_9_5.ino` via Arduino IDE

(Board: **ESP32-S3**, Partition: **Huge APP 3MB**)

2. Connect to WiFi via the setup page

3. Add to Claude Desktop `claude_desktop_config.json`

4. Ask Claude to `get_lua_guide` — then start experimenting with INDI and ADC!

### ❤️ Support the Project on BOOTH

This firmware is **free and open** — always will be.

If LUNA has been useful to you, the same firmware

(pre-compiled binary, ready to flash — no Arduino IDE needed)

is available on BOOTH as a **pay-what-you-feel download**:

👉 **https://onstepninja.booth.pm/**

Your support — however small — directly funds continued development.

New modules, new editions, new ideas.

Every download is a vote for the next version. Thank you. 🙏
