Whispers of the Wild: Exploring the Timeless Beauty of Indian Mountains and Forest Landscapes

Maldevta, Dehradun district , Uttarakhand

PC: RRJ

There are places where words fall silent, where the air feels like a lover’s breath, and the trees whisper secrets older than time. The mountains stand like ancient guardians, watching over valleys kissed by morning mist, while the forests stretch endlessly soft, green cathedrals where the sunlight dances in golden silence.

I have always believed that nature holds the kind of love we often seek in people wild, quiet, patient, and eternal. In every rustling leaf, every echo between the peaks, there is a story of longing and serenity waiting to be felt. This blog is my love letter to those untouched corners of the world where the heart finds peace and the soul feels free.

Whispers of the Wild

I walked where rivers speak in song,

Where pines stand tall and winds belong.

Where light through leaves began to dance,

And time slowed down in nature's trance.

The hills would hum, the trees would sigh,

The skies would blush as clouds passed by.

Each step I took, a story grew

Of earth and heart, and skies so blue.

Not just a place I chanced to roam,

But memories carved in bark and stone.

For in the wild, I found my part

A quiet world that touched my heart.

Come, walk with me through this landscape of dreams where the sky meets the earth, and time moves only to the rhythm of the wind.

A Sunrise That Felt Like Love – Somewhere in Himachal

Somewhere along a quiet bend in the hills of Himachal, the morning sun rose not just over the trees, but through them its golden light gently weaving through their branches like a lover’s fingers tracing poetry in silence. The forest stood still, wrapped in the hush of early light, and the mountains watched over with timeless grace. In that soft moment, the world felt tender like it was holding its breath just for me. Or maybe for us. It wasn’t just a sunrise; it was a feeling of warmth, of longing, of love whispered by the earth itself.

The night in Tehri felt like a dream draped in velvet. Hills whispered in the dark, their lights twinkling like stars that had gently fallen to earth. The lake held every shimmer with grace, mirroring a sky stitched with quiet magic. It was the kind of night you don’t just see, you feel it in your chest, like a soft hush between two heartbeats. Standing by the water, with the hills aglow and the air tenderly still, it felt like love calm, glowing, and endlessly deep.

Koti, Uttarakhand — A Place That Whispers to the Soul

In the quiet embrace of Koti, Uttarakhand, time didn’t move, it lingered. Blue walls held stories of art yet to be painted, while a woven lamp spilled warmth like a heartbeat in the dark. A single pink blossom reached gently into the night like a lover’s hand in search of meaning. And when the morning came, the mountains rose like a slow sigh under a golden sky,soft, layered, and infinite. Even the flowers on the rooftop seemed to stretch with joy, as if knowing this place was not just made of earth and stone, but of dreams, stillness, and stories waiting to be written.

The Art of Seeing, Feeling, and Remembering Nature

Nature doesn't just exist to be seen, it waits to be felt. In every silent sunrise, rushing stream, quiet deer, or twisted old tree, there is a gentle invitation to slow down and reconnect with the earth, with stillness, and often, with yourself.

Each landscape you've walked through from the misty hills of Himachal to the forests of Cubbon Park, the wild rivers of Kiari Kham to the pine-laced skies of Ooty has its own heartbeat. And through your lens, you've done more than capture an image… you’ve held onto a feeling.

Photography becomes something sacred in these moments. It is not about the perfect shot, but about preserving the poetry of a place, the unspoken hush between nature and the soul. These frames are not just pictures. They are stories, moods, memories the kind you revisit not with your eyes, but with your heart.

So keep wandering. Keep watching. Keep letting the world move you, quietly and completely.

Because when you learn to see the world with wonder,
every tree becomes a storyteller, and every horizon a home.

Run AI on ESP32: How to Deploy a Tiny LLM Using Arduino IDE & ESP-IDF (Step-by-Step Guide)

Introduction

What if I told you that your tiny ESP32 board the same one you use to blink LEDs or log sensor data could run a Language Model like a miniature version of ChatGPT? 

Sounds impossible, right? But it’s not.

Yes, you can run a Local Language Model (LLM) on a microcontroller!

Thanks to an amazing open-source project, you can now run a Tiny LLM (Language Learning Model) on an ESP32-S3 microcontroller. That means real AI inference text generation and storytelling running directly on a chip that costs less than a cup of coffee 

In this blog, I’ll show you how to make that magic happen using both the Arduino IDE (for quick prototyping) and ESP-IDF (for full control and performance). Whether you’re an embedded tinkerer, a hobbyist, or just curious about what’s next in edge AI this is for you.

Ready to bring AI to the edge? Let’s dive in!  

In this blog, you'll learn two ways to run a small LLM on ESP32:

1. Using Arduino IDE
2. Using ESP-IDF (Espressif’s official SDK)

Understanding the ESP32-S3 Architecture and Pinout

The ESP32-S3 is a powerful dual-core microcontroller from Espressif, designed for AIoT and edge computing applications. At its heart lies the Xtensa® LX7 dual-core processor running up to 240 MHz, backed by ample on-chip SRAM, cache, and support for external PSRAM—making it uniquely capable of running lightweight AI models like Tiny LLMs. It features integrated Wi-Fi and Bluetooth Low Energy (BLE) radios, multiple I/O peripherals (SPI, I2C, UART, I2S), and even native USB OTG support. The development board includes essential components such as a USB-to-UART bridge, 3.3V LDO regulator, RGB LED, and accessible GPIO pin headers. With buttons for boot and reset, and dual USB ports, the ESP32-S3 board makes flashing firmware and experimenting with peripherals effortless. Its advanced security features like secure boot, flash encryption, and cryptographic accelerators also ensure your edge AI applications stay safe and reliable. All of these capabilities together make the ESP32-S3 a perfect platform to explore and deploy tiny LLMs in real-time, even without the cloud.

What Is This Tiny LLM?

• Based on the llama2.c model (a minimal C-based transformer).
• Trained on TinyStories dataset (child-level English content).
• Supports basic token generation at ~19 tokens/sec.
• Model Size: ~1MB (fits in ESP32-S3 with 2MB PSRAM).

What You Need?

Item	Details
Board	ESP32-S3 with PSRAM (e.g., ESP32-S3FH4R2)
Toolchain	Arduino IDE or ESP-IDF
Model	tinyllama.bin (260K parameters)
Cable	USB-C or micro-USB for flashing

Method 1: Using Arduino IDE

Step 1: Install Arduino Core for ESP32

• Open Arduino IDE.

• Go to Preferences > Additional Board URLs

Add:

https://raw.githubusercontent.com/espressif/arduino-esp32/gh-pages/package_esp32_index.json

• Go to Board Manager, search and install ESP32 by Espressif.

Step 2: Download the Code

The current project is in ESP-IDF format. For Arduino IDE, you can adapt it or wait for an Arduino port (coming soon). Meanwhile, here's a simple structure.

• Create a new sketch: esp32_llm_arduino.ino
• Add this example logic:

#include <Arduino.h>
#include "tinyllama.h" // Assume converted C array of model weights

void setup() {
  Serial.begin(115200);
  delay(1000);
  Serial.println("Starting Tiny LLM...");
  // Initialize model
  llama_init();
}

void loop() {
  String prompt = "Once upon a time";
  String result = llama_generate(prompt.c_str(), 100);
  Serial.println(result);
  delay(10000); // Wait before next run
}

    

Note: You'll need to convert the model weights (tinyllama.bin) into a C header file or read from PSRAM/flash.

Step 3: Upload and Run

• Select your ESP32 board.
• Upload the code.
• Open Serial Monitor at 115200 baud.
• You’ll see the model generate a few simple tokens based on your prompt!

Method 2: Using ESP-IDF

Step 1: Install ESP-IDF

Follow the official guide: https://docs.espressif.com/projects/esp-idf/en/latest/esp32/get-started/

Step 2: Clone the Repo

git clone https://github.com/DaveBben/esp32-llm.git
cd esp32-llm

Step 3: Build the Project

idf.py set-target esp32s3
idf.py menuconfig  # Optional: Set serial port or PSRAM settings
idf.py build

Step 4: Flash to Board

idf.py -p /dev/ttyUSB0 flash
idf.py monitor

Output:

You’ll see generated text like:

Artificial Intelligence (AI) and Large Language Models (LLMs) are everywhere now; starting from smart assistants to AI copilots, chatbots, and content generators. If you’re in tech, product, marketing, or just exploring this space, understanding the jargon is essential to join meaningful conversations.

Here’s a breakdown of must-know AI and LLM terms, with simple explanations so you can talk confidently in any meeting or tweet storm.

Core AI Concepts

1. Artificial Intelligence (AI)

AI is the simulation of human intelligence in machines. It includes learning, reasoning, problem-solving, and perception.

2. Machine Learning (ML)

A subset of AI that allows systems to learn from data and improve over time without explicit programming.

3. Deep Learning

A type of ML using neural networks with multiple layers—great for recognizing patterns in images, text, and voice.

LLM & NLP Essentials

4. Large Language Model (LLM)

An AI model trained on massive text datasets to understand, generate, and manipulate human language. Examples: GPT-4, Claude, Gemini, LLaMA.

5. Transformer Architecture

The foundation of modern LLMs—introduced by Google’s paper “Attention Is All You Need”. It enables parallel processing and context understanding in text.

6. Token

A piece of text (word, sub-word, or character) processed by an LLM. LLMs think in tokens, not words.

7. Prompt

The input given to an LLM to generate a response. Prompt engineering is the art of crafting effective prompts.

8. Zero-shot / Few-shot Learning

• Zero-shot: The model responds without any example.
• Few-shot: The model is shown a few examples to learn the pattern.

Training & Fine-Tuning Jargon

9. Pretraining

LLMs are first trained on general datasets (like Wikipedia, books, web pages) to learn language patterns.

10. Fine-tuning

Adjusting a pretrained model on specific domain data for better performance (e.g., medical, legal).

11. Reinforcement Learning with Human Feedback (RLHF)

Used to align AI output with human preferences by training it using reward signals from human evaluations.

Deployment & Use Cases

12. Inference

Running the model to get a prediction or output (e.g., generating text from a prompt).

13. Latency

Time taken by an LLM to respond to a prompt. Critical for real-time applications.

14. Context Window

The maximum number of tokens a model can handle at once. GPT-4 can go up to 128k tokens in some versions.

AI Ops & Optimization

15. RAG (Retrieval-Augmented Generation)

Combines search and generation. Useful for making LLMs fetch up-to-date or domain-specific info before answering.

16. Embeddings

Numerical vector representations of text that capture semantic meaning—used for search, clustering, and similarity comparison.

17. Vector Database

A special database (like Pinecone, Weaviate) for storing embeddings and retrieving similar documents.

Governance & Safety

18. Hallucination

When an LLM confidently gives wrong or made-up information. A major challenge in production use.

19. Bias

LLMs can reflect societal or training data biases—gender, race, politics—leading to ethical concerns.

20. AI Alignment

The effort to make AI systems behave in ways aligned with human values, safety, and intent.

Some Bonus Buzzwords For You...

• CoT (Chain of Thought Reasoning): For better logic in complex tasks.
• Agents: LLMs acting autonomously to complete tasks using tools, memory, and planning.
• Multi-modal AI: Models that understand multiple data types—text, image, audio (e.g., GPT-4o, Gemini 1.5).
• Open vs. Closed Models: Open-source (LLaMA, Mistral) vs proprietary (GPT, Claude).

What is MCP Server and Why It's a Game-Changer for Smart Applications?

 

In a world where AI and smart applications are rapidly taking over, the need for something that connects everything from voice assistants to smart dashboards has become essential. That’s where the MCP Server comes in.

But don’t worry , even if you’re not a tech person, this blog will explain what MCP is, what it does, and how it’s used in real life.

What is MCP Server?

MCP stands for Multi-Channel Processing Server. Think of it like a super-smart middleman that connects your app, AI engines (like ChatGPT or Gemini), tools (like calendars, weather APIs, or IoT devices), and users — and makes them all talk to each other smoothly.

Simple Example:

You want your smart app to answer this:

“What's the weather like tomorrow in Mumbai?”

Instead of programming everything manually, the MCP Server takes your question, sends it to an AI (like ChatGPT, Google Gemini, DeepSeek, Goork, Meta LLM, Calude LLM etc.), fetches the weather using a weather API, and replies — all in one smooth flow.

Let's have more example to get more into this and have pleasant vibe while reading this article.

Example 1: Book a Meeting with One Sentence

You say:
“Schedule a meeting with Rakesh tomorrow at 4 PM and email the invite.”

What happens behind the scenes with MCP:

1. MCP sends your sentence to ChatGPT to understand your intent.
2. It extracts key info: "Rakesh", "tomorrow", "4 PM".
3. MCP checks your Google Calendar availability.
4. MCP calls email API to send an invite to Rakesh.
5. Sends a response:

“Meeting scheduled with Rakesh tomorrow at 4 PM. Invite sent.”

✅ You didn’t click anything. You just said it. MCP did the rest.

 Example 2: Factory Operator Asking About a Machine

A technician says into a tablet:
“Show me the error history of Machine 7.”

MCP steps in:

1. Sends command to AI to understand the request.
2. Uses an internal tool to fetch logs from Industrial IoT system.
3. Formats and displays:

“Machine 7 had 3 errors this week: Overheating, Power Drop, Sensor Failure.”

✅ No menu clicks, no filter settings. Just ask — get the answer.

Example 3: Customer Asking About Order

Customer types on your e-commerce chatbot:
“Where is my order #32145?”

MCP does the magic:

1. Passes message to AI (ChatGPT or Gemini) to extract order number.
2. Connects to Order Tracking API or Database.
3. Replies:

“Your order #32145 was shipped today via BlueDart and will arrive by Monday.”

✅ It looks like a chatbot replied, but MCP did all the heavy lifting behind the scenes.

Example 4: Playing Music with Voice Command

You say to your smart home app:
“Play relaxing music on Spotify.”

Behind the curtain:

1. MCP sends request to AI to understand mood ("relaxing").
2. Connects to Spotify API.
3. Plays a curated playlist on your connected speaker.

✅ One sentence — understood, processed, and played!

Multilingual Translation Support

A user says:
“Translate ‘नमस्कार, बाळा, मी ठीक आहे. तू कसा आहेस?’ into English and email it to my colleague Karishma J.”

What MCP does:

1. Uses AI to extract the text and target language.
2. Uses a Translation Tool (like Google Translate API).
3. Sends email using Gmail API.
4. Responds with:

“‘Reply to Karishma J: Hi Babe, I am good . How Are You ?’ has been sent to your colleague.”

✅ Language, tools, email — all connected seamlessly.

How Does MCP Work?

Let’s break it down in a flowchart:

• User sends a question or command
• MCP Server decides what needs to be done
• It may talk to an AI Engine for understanding or generation
• It may call external tools like APIs for real-time data
• Everything is combined and sent back to the User

Real-World Use Cases

1. Voice Assistants & Chatbots

You say: “Remind me to water the plants at 6 PM.”
MCP can:

• Understand it (via ChatGPT/Gemini)
• Connect to your calendar/reminder tool
• Set the reminder

2. Smart Dashboards

In factories or smart homes, MCP can:

• Show live data (like temperature, machine status)
• Answer questions like: “Which machine needs maintenance today?”
• Predict future issues using AI

3. Customer Support

A support bot can:

• Read your message
• Connect to company database via MCP
• Reply with real-time shipping status, refund policies, or FAQs

4. IoT Control Systems

Say: “Turn off the lights if no one is in the room.”
MCP connects:

• AI (to interpret the command)
• Sensors (to check presence)
• IoT system (to turn lights on/off)

Let's Little Bit Deep Drive into Technical example demo aspect:

Run this on your machine/ Terminal:

1. Make a python code file with name : mcp_server.py

2. Define and add get_weather tool like this mcp_server.py:

#Programming Language python:
def get_weather(city: str):
    # Connect to weather API
    return f"The weather in {city} is 31°C, sunny."

#Add an AI Engine
#Register ChatGPT (or Gemini) with MCP so it can understand commands:
#Programming Language python:

mcp.register_ai_engine("chatgpt", OpenAI(api_key="your-key"))

Now Run this code:

python mcp_server.py

User Command

Now send:

“Tell me the weather in Bangalore.”

The AI will extract the city name, MCP will call get_weather("Bangalore"), and return the answer!

Output:

"The weather in Bangalore is 28°C with light rain."

Component	Role	Explained Simply
AI Engine	Understands and responds	Like your brain understanding the question
Tool (Plugin/API)	Performs actions (like fetch data)	Like your hands doing the task
MCP Server	Manages the whole flow	Like your body coordinating brain and hands

Why MCP Server is Different from Just APIs

Feature	Normal API	MCP Server
Multiple tools	❌	✅
AI integration	❌	✅
Flow-based execution	❌	✅
Human-like interaction	❌	✅

Business Impact

• Saves development time

Instead of coding everything, just plug tools and logic into MCP.

• Brings smart AI features

Chatbots and assistants become really smart with MCP + AI.

• Customizable for any industry

Healthcare, manufacturing, e-commerce — all can use MCP.

Is It Secure?

Yes. You can host your own MCP server (on cloud or on-premises). All keys, APIs, and access are controlled by you.

Here's a clear High-Level Architecture (HLD) for a system that uses:

• FastAPI as the backend service
• MCP Server to coordinate between AI, tools, and commands
• Voice Assistant as input/output interface
• Vehicle-side Applications (like infotainment or control apps)

HLD For: Smart In-Vehicle Control System with Voice + MCP + FastAPI

Architecture Overview

The system allows a user inside a vehicle to:

• Talk to a voice assistant
• MCP Server interprets the request (via AI like ChatGPT)
• FastAPI routes control to the correct service
• Executes commands (e.g., play music, show location, open sunroof)

Components Breakdown

1. Voice Assistant Client (In Vehicle)

• Wake-word detection (e.g., “Hey Jeep!”)
• Captures voice commands and sends to MCP Server
• Text-to-Speech (TTS) for responses

2. MCP Server

• Receives text input (from voice-to-text)
• Processes through AI (LLM like GPT or Gemini)
• Invokes tools like weather API, calendar, media control
• Sends command to FastAPI or 3rd-party modules

3. FastAPI Backend

• Acts as the orchestrator for services
• Provides REST endpoints for:
• Music Control
• Navigation
• Climate Control
• Vehicle APIs (like lock/unlock, AC, lights)
• Handles auth, logging, fallback

4. Tool Plugins

• Weather API
• Navigation API (e.g., HERE, Google Maps)
• Media API (Spotify, Local Player)
• Vehicle SDK (Uconnect/Android Automotive)

5. Vehicle Control UI

• Screen interface updates in sync with voice commands
• Built using web technologies (JS + Mustache for example)

    B --> C[AI Engine<br>ChatGPT/Gemini]

    B --> D[FastAPI Service Layer]

    B --> E[External Tools<br>(Weather, Calendar, Maps)]

    D --> F[Vehicle App Services<br>(Music/Nav/Climate)]

    F --> G[Vehicle Hardware APIs]

    F --> H[In-Vehicle UI]

    H --> A

Example Flow: “Play relaxing music and set AC to 22°C”

Voice Command Flow in Vehicle Using MCP Server

Let’s walk through how a smart in-vehicle system powered by MCP Server handles a simple voice command:

 User says the command inside the vehicle:

“Play relaxing music and set AC to 22°C”

Step 1: Voice Assistant Converts Speech to Text

The voice assistant listens and translates the spoken sentence into text using voice-to-text technology.

 Step 2: Text Sent to MCP Server

The voice command (in text form) is now sent to the MCP Server for processing. 

Step 3: MCP Uses AI to Understand Intents
The AI engine (like ChatGPT or Gemini) analyzes the sentence and extracts multiple intents:

• Intent 1: Play relaxing music
• Intent 2: Set air conditioner to 22°C

Step 4: MCP Sends Commands to FastAPI Services

• Music Command → FastAPI → Music Controller
• AC Command → FastAPI → Climate Controller

 Step 5: Action & Feedback

• Music starts playing
• AC is set to the desired temperature
• Dashboard/UI reflects the change

Step 6: Voice Assistant Responds to User

“Now playing relaxing music. AC is set to 22 degrees.”

Key Benefits
