Post Body:
Put together a browser-based 3D circuit simulator over the last few weeks: https://luvaai.in
The idea was to make something zero-install where you can just open a tab, drop components on a breadboard in 3D, wire them up, and run a quick simulation without signing up or dealing with desktop software like Multisim or LTspice.
How it's built
The frontend is React 19, TypeScript, and Vite, with Three.js handling the 3D canvas and raycasting for component placement. State is managed with Zustand (Redux was overkill for this).
