Parallax: Turning a Phone Video into a Walkable Digital TwinWalk through a building with a phone, upload the video, and get a photorealistic 3D Gaussian Splatting twin you can walk through in the browser, with search, wall collision and A* walking directions. How we recover floor, scale and walls from a unitless splat.Oct 2026

VASIMOV: Building a Virtual Asimov 1 That the Real SDK Can't Tell ApartA MuJoCo digital twin of Menlo's Asimov 1 humanoid that speaks the official UDP wire protocol, runs the official 78-obs to 23-action locomotion policy at 50 Hz, and labels every field it emits as real, approximate, or placeholder.Oct 2026

Driving a Humanoid from a Phone: Asimov 1 3D Teleoperation in React NativeA React Native and Expo controller that renders the Asimov 1 humanoid locally with Three.js on expo-gl, fed by 288-byte binary state packets at 50 Hz, plus a lightweight browser controller built on the same protocol.Oct 2026

UIKey: Compiling a Live Website into a Prompt an LLM Can Actually UseA browser extension, a design-token compiler and a pseudo-JSX formatter that turn any page's computed styles and geometry into a compact UI manifest for AI code generators, plus an honest look at what is still scaffolding.Oct 2026

EdgeMed Memory Lab: An Offline Clinical Memory Vault on Qdrant EdgeHow our team built a synthetic-data-only memory and search prototype for Code Cubicle 6.0 (PS03): SQLCipher as the source of truth, an embedded Qdrant Edge shard for vectors, hybrid search in about 4 ms, staff workspaces over a private LAN, and a sync boundary that only lets reviewed reference data out.Sep 2026

AndroPlay: Zero-Lag Playback on an LG CreateBoard, Controlled From a PhoneOne Android app with two roles: a board that pre-syncs everything and plays from local storage with a warm standby player, and a phone that controls it over BLE in the room or Redis pub/sub from anywhere.Oct 2026

Nyaya Flow: Voice-First Legal Navigation for India, Built Around a Case, Not a ChatHow I built Nyaya Flow, a voice-first, multilingual legal navigation app (Expo, Gemini, Gnani.ai STT, Firebase) that turns a spoken grievance into a structured case with sourced next steps. It was a shortlisted finalist at Build in AI for India, Delhi.Sep 2026

ExelSnap: Chatting with Spreadsheets on a Laptop, with No Cloud and No Made-Up NumbersAn Electron desktop app where a small local model answers questions about Excel and CSV files by writing read-only DuckDB queries. The model never sees the rows, and every number it states has a query behind it.Oct 2026

TJFLOW: A Real-Time Kanban Workspace on Firestore Listeners and Security RulesBuilding TJFLOW, a real-time project workspace with a Kanban board, chat, activity logs and a reviewer test mode, using React 19, Vite, Tailwind v4 and Firebase, and the listener and security-rule trade-offs behind it.Sep 2026

ECHO//LOOP: Building a Time-Loop Puzzle Game Where Your Past Self Is Your CoworkerA minimalist top-down puzzle game in vanilla JavaScript and Canvas 2D, where every rewind leaves behind an Echo that replays exactly what you did. This post covers the fixed-timestep loop and the record and replay design that keeps those Echoes deterministic.Sep 2026

Mint Zoom: Building My Own Pinch-to-Zoom for Chrome on Linux MintChrome on Linux Mint Cinnamon never gave me a smooth, visual trackpad zoom. So I wrote a 400-line content script that does it with a single CSS matrix, a cursor-anchored zoom equation, and a tiny easing loop for scrolling.May 2026

reddit-core: A Faceted Search Front-End for Reddit's Public ArchivesReddit's own search can't filter by date range, score, or author together, and it can't see what has already scrolled out of reach. reddit-core is a small React app on top of the PullPush archive API that can, plus a one-click hand-off into my curation CMS.Feb 2026

QuoraFormatter: A Zero-Backend Workbench for Long-Form Curation PostsAssembling a twenty-image curation post in Quora's editor was slow and error-prone. QuoraFormatter is a single HTML file that turns a library of images, captions, and sources into a numbered, paste-ready post.Jul 2025

The Artful Eye: Geometry, Light, and Visual HarmonyReflections from curating The Artful Eye on Quora: analyzing architectural composition, light dynamics, visual balance, and human perception.Aug 2026
