## 📺 Video Topics & Demonstrations

### 1. Making Your Own Custom Hydrogen Widget
* **Hook:** *"Don't just use Hydrogen—extend it. Build your own interactive UI widget in minutes."*
* **What to Show:**
  * **Architecture:** Zero-dependency web components with isolated Shadow DOM that adapt seamlessly to Hydrogen's dark and light themes.
  * **Data Feeding:**
    * Inline JSON via `<script type="application/json">` (crucial for sandboxed wiki iframes with `connect-src 'none'`).
    * Direct DOM property binding (`element.data = { ... }`).
    * URL/fetch binding for connected environments.
  * **Integration Points:**
    * Drop-in web component tags (`<adom-...>`).
    * Markdown tag integration (`::my-widget{src="..."}` via `adom-wiki widgets`).
    * Hosting in Hydrogen webview tabs and wiki `readme.html` files.
  * **Demo Example:** Building a live status indicator or mini pinout/telemetry component that reacts to hovered nets and real-time state.

### 2. Building Your Own Bridge with the Bridge SDK (Showcase: The Advanced SPICE Bridge)
* **Hook:** *"Give the AI hands on your desktop: turn clunky, closed-source desktop tools into instant AI superpowers."*
* **The Killer Problem: Vendor-Encrypted SPICE Models:**
  * Power IC vendors like **Texas Instruments** distribute proprietary macromodels encrypted with Cadence keys (`$CDNENCSTART`).
  * Open-source engines like `ngspice` cannot decrypt or run them.
  * **PSpice for TI** is required to simulate them, but it has **no headless batch CLI**—it is strictly a Windows GUI application.
* **The Naive Way (Burning 50k Tokens):**
  * Without a custom bridge, raw AI uses generic OS automation: pushing netlists, spawning `pspice.exe`, sleeping 14 seconds, taking screenshots, vision-clicking the "Run" button, polling `.out` files, and pulling raw text CSDF dumps.
  * *Result:* 16 fragile tool calls, ~49,000 tokens burned per simulation, and easily broken by unexpected popups.
* **The Bridge SDK Solution (`spice_bridge`):**
  * **`bridge.json` Manifest:**
    * Declares domain verbs like `spice_simulate`, `spice_sweep`, `spice_probe`.
    * Manages runtime lifecycle on the Windows host (`python` or `node`).
    * Detects running PSpice/LTspice instances (`detect`).
  * **Superpowers Unlocked by the Bridge:**
    1. **Single-Call Deterministic Verbs:** The AI issues `spice_simulate {"engine": "pspice_ti", "netlist": "buck.cir"}` and gets structured metrics back in **1 call**.
    2. **Local Binary Waveform Decimation:** High-frequency switching simulations produce 500 MB to 2 GB binary `.raw` / `.csd` files. The bridge parses them locally on the Windows host, extracts scalar metrics (`v_ripple_pk`, `overshoot_pct`, `efficiency`), downsamples the million-point curve to a 500-point vector, and passes lightweight JSON to Hydrogen without choking cloud relays.
    3. **Automated Convergence Recovery:** When SPICE hits `Timestep too small` at $t = 1.42\text{ ms}$, the bridge catches the failure, inspects the `.out` log for the oscillating node, relaxes `reltol` or injects `cshunt`, and retries automatically.
    4. **Multi-Threaded Parametric & Monte Carlo Sweeps:** Spawns batch runs across CPU cores on the host for corner/temperature sweeps and returns the statistical yield chart.
    5. **Direct Streaming to Hydrogen Widgets:** Streams real-time simulation progress and decimated curves straight into a Hydrogen webview tab or `<adom-spice>` canvas.
* **Other Engines that Benefit:**
  * **LTspice (Analog Devices):** Bypasses first-run popups, parses proprietary binary `.raw` files directly.
  * **QSPICE (Qorvo):** Interfaces with high-speed C++/Verilog behavioral blocks and encrypted SiC/GaN models.

### 3. Using AI to Generate Custom Avatars
* **Hook:** *"Create your own tech-nerd CEO persona or team avatar directly with AI inside Hydrogen."*
* **What to Show:**
  * **Concept:** Directing the AI to design vector SVG avatars with distinct persona traits, accessories, and consistent styling (reference: `john/avatar`).
  * **Prompting & Crafting:**
    * Establishing visual style (clean vector illustration, bold line work, flat shading, color palette).
    * Generating multi-pose or profile vs. full-figure variants.
  * **Publishing to Hydrogen & Wiki:**
    * Storing SVG sources and exporting web-ready SVG/PNG renders.
    * Setting up an avatar app or profile asset on the Adom Wiki.
    * Integrating the avatar into Hydrogen headers, chat threads, and card banners.

### 4. The Built-in Pencil Markup Tool (Visual Problem Reporting)
* **Hook:** *"Stop typing long explanations of where your bug is—just circle it with the pencil."*
* **What to Show:**
  * **The Pencil Tool:** The native pencil icon built into Hydrogen that opens an immediate drawing canvas over the workspace.
  * **Multi-Color Annotations:**
    * Drawing freehand circles, arrows, and boxes in distinct colors (red for errors, yellow for warnings, blue/green for suggestions).
    * Highlighting specific schematic net crossings, 3D PCB layout choke points, or UI glitches.
  * **Multimodal AI Grounding:**
    * When submitted, Hydrogen captures the annotated visual frame and binds it to your prompt.
    * The AI directly parses the colored highlights without guessing coordinates or reference designators (e.g., *"Why is this trace in the red circle violating clearance?"*).

### 5. Supercharging Multi-Box Control with Adom Bridge Mesh
* **Hook:** *"Control your laptop, lab workstation, and Azure VM from one prompt with zero cloud lag."*
* **What to Show:**
  * **The Mesh Architecture:**
    * Durable Ed25519 node identities (`~/.adom/mesh/node.key`).
    * End-to-end encrypted QUIC transport (iroh) over LAN via mDNS, with automatic fallback through the Adom-hosted cloud relay (`route: {via: "mesh"}`).
  * **Key Capabilities:**
    * **Targeting Machines:** Using `--target <machine>` to dial direct peer-to-peer connections.
    * **Peer File Transfers & Screenshots:** `pull_file --target <peer>` streams directly between machines with SHA-256 verification—no relay bottlenecks.
    * **Mirrored Permission Prompts:** Human-in-the-loop permission cards (shell approval, credential grants) mirror across all your devices, allowing you to approve an action on whichever box you are sitting at.
    * **The Mesh View Panel:** Launching `desktop_ui_panel {"panel":"mesh"}` to view the live network topology graph of all your connected nodes, latencies, and WSL2/container children.
    * **Mesh Modes:** Switching between `relay` (firewall-free default), `direct` (high-speed local LAN), and `off`.

### 6. High-Performance Screen Recording (H.264 & H.265 / HEVC)
* **Hook:** *"Record silky-smooth 60 FPS video of your workflow straight to compressed H.264 or ultra-dense H.265."*
* **What to Show:**
  * **The Native Bridge Recorder:** Using `desktop_record_start` and `desktop_record_stop` for zero-overhead, headless or windowed recording.
  * **Codecs & Hardware Acceleration:**
    * Inspecting available hardware encoders with `desktop_record_encoders` (NVENC, Intel Quick Sync, AMD AMF).
    * H.264 for universal compatibility and instant playback.
    * H.265 / HEVC (`codec: "h265"`) for ~40% smaller file sizes at pristine quality.
  * **Audio & Framing Features:**
    * High-fidelity system audio loopback capture via WASAPI.
    * Window-specific recording (`desktop_record_window_start`) vs monitor-level capture.
    * The discreet 4×4 pixel teal dot recording indicator (no obtrusive watermark or motion distortion).

### 7. Hands-Free Mode: Let the AI Read Its Answers to You
* **Hook:** *"Driving, soldering, or across the room? Say "read it to me" and every answer comes out loud."*
* **What to Show:**
  * **One Phrase Turns It On:** Say "hands free", "read it to me", "I'm driving", or "read your last answer". The AI loads the `hands-free` skill and speaks its replies instead of writing walls of text.
  * **It Stays On:** Every reply after that is narrated, about 30 to 60 seconds each, until you say "I'm back at my desk".
  * **One Shared Player for Every Thread:** Clips from all your AI threads queue in one Adom TTS player. Each one starts with the thread's name and carries a one-line description, so with five threads running you always know who is talking.
  * **Verified Playback:** `adom-tts say ... --play --confirm` waits until the clip has actually played to you, and clips buffer and retry through connection drops.
  * **History Drawer:** Missed something? Every clip stays in the player's History for an instant replay.
  * **Demo Example:** With a long build running, say "read me your last answer" and hear a 79-second status report while your hands stay on the bench.
