An infrastructure intelligence platform built on 8,600 verified Bangladeshi network cell towers to locate emergency callers without GPS, identify shared tower opportunities, analyze highway connectivity, and run in-browser diagnostics.

Project Overview:

The most precious thing we own is our life. While many developed countries have put their name in the absolute pinnacle of tech industry. Developing and under Developing countries suffer a massive issue due to lack in advancements in tech. People, women, kids suffer from natural disasters and Monsoon floods regularly isolate families in districts in Bangladesh such as Sylhet, Sunamganj, and Feni. Most residents in affected rural areas rely on basic feature phones rather than smartphones with active GPS or mobile data. When calling emergency lines, they cannot share a digital map pin. However, their phone diagnostic screen displays their serving base station codes: the Location Area Code and Cell Identifier.

At the same time, mobile network operators frequently duplicate infrastructure by erecting towers within walking distance of each other, incurring redundant land leases and diesel generator costs. Freight and cold-chain logistics fleets also face coverage dropouts along major trade routes because dispatchers lack route-specific carrier performance data.

KUTNI MCC470 addresses these operational problems using a verified dataset of 8,600 physical cell towers across Bangladesh (MCC 470). It does not use simulated points, mock coordinates, or placeholder records. Every calculation runs on confirmed base stations belonging to Grameenphone, Robi, Banglalink, and TeleTalk.

It's not just a sci-fi concept, this platform not only helps in saving someone's life, but also plays a crucial role in Startups. (From a person getting saved from a life threatening disaster to a Real Estate company using this feature to give their customer's a bit of unique service by telling them which SIM cards to avoid or use for that specific home, ultimately earn some money-money in their wallets).

Core Platform Capabilities:

1. Interactive 3D Globe Network Map

It renders all 8,600 verified network cell towers present in Bangladesh on a 3D spherical Earth using MapLibre GL. Includes three conjoined map controls:

1. Real-life Satellite: Toggle photorealistic ArcGIS world imagery tiles.

2. 2D to 3D Globe: Toggle spherical Earth projection.

3. Reload and Reset: Recenter camera directly over Bangladesh.

It provides real-time filtering by operator (Grameenphone, Robi, Banglalink, TeleTalk) and radio generation (4G LTE, 3G UMTS, 2G GSM).

2. Emergency Phone Triangulation

If an emergency caller uses a basic phone during a flood, a rescue volunteer can ask for the tower numbers displayed on their screen (Location Area Code and Cell ID). It matches those codes to the physical mast location and renders an approximate search perimeter and then calculates the three nearest backup towers from alternative carriers within 10 kilometers using the Haversine formula. Ultimately generating a bilingual field dispatch sheet in English and Bengali with compass bearings for boat crews.

3. Tower Sharing and Co-Location Optimizer

By constructing a cell mast requires significant capital, recurring land rent, and diesel generator fuel. It evaluates distances across all 8,600 towers in real time. Later identifies over 1,000 locations where competing carriers built standalone towers within 250 meters of one another and finally computes annual operational savings in Bangladeshi Taka achieved by consolidating onto a shared structure.

4. Highway Transport Corridors

Freight trucks, delivery vans, and emergency vehicles require continuous network reception along trade routes. Kutni inspects a whole bunch of cell tower distribution along primary national arteries: N1 (Dhaka to Chittagong), N2 (Dhaka to Sylhet), N5 (Dhaka to Bogra), and N8 (Dhaka to Khulna via the Padma Bridge). Furthermore it compares 4G LTE high-speed coverage against 2G GSM voice fallback. Finishing off by formulating primary and failover Dual-SIM hardware configurations for vehicle telematics units.

5. Genuine x86 Virtual Machine Sandbox

Kutni integrates a client-side WebAssembly x86 PC emulator running directly in the browser (meaning real life Operating Systems). It boots graphical KolibriOS or lightweight Linux BusyBox for offline diagnostic calculations and field scripts without server dependence.

6. Systems Architecture Dossier and Plain English Guide

Kutni outlines technical specifications, dataset schemas, and architectural credentials. It furthermore provides a step-by-step interactive walkthrough that explains every operational tool clearly.

Design System and Interface:

1. Color Scheme: Deep obsidian foundation (#070c0e), mint phosphor accents (#00d2be), imperial gold highlights (#d4af37), and telecom cyan (#00A8E8).

2. Tactile Surfaces: Glass-morphic panels with metallic borders, high-contrast status readouts, and responsive mobile and desktop viewports.

3. Audio Feedback: Mechanical clicks and tones synthesized using the Web Audio API for tactile operational confirmation.

☀️ The glass is blank. The wall isn't.

Hold it up to a window and there's nothing on it. No print. No paint. Then the sun comes through, and a face lands on the wall.

That's a caustic lens. Clear acrylic, its surface shaped so precisely that sunlight draws a picture. They're beautiful, and almost nobody sells them. Every single one needs its own optics solve.

🔆 HELIODOR

A studio that writes a name, or a face, in sunlight.

Type a name, or drop in a photo. Your browser solves the lens. No server, no AI credits. A ray-traced proof shows the light before anything is cut. Then it checks the glass. The portrait in the video: 3.3° slope, 3.6 mm deep, match 0.80. Ready to cut.

From your city and your window, it finds every day the light is sharp and adds them to your calendar.

Photos were the hard part. A full-contrast face came out 7.1 mm deep, over the 6 mm cut line. So every photo now keeps a soft base glow.

Behind it runs a real workshop. Orders move through each stage on the Workshop board. Today's lenses nest onto one acrylic sheet. Approved pieces hang on the public Light Wall.

One photo. One beam of sun. Zero AI credits.

So whose face goes on your wall? The sun does the rest. ✨

This is such a creative concept! Turning natural sunlight into a medium for portrait creation is a genuinely unique idea. I especially like how you've connected the creative side with a practical workflow, from checking light conditions to production and order tracking. The zero-AI-credits aspect makes it even more interesting!
