About CircuitForge

CircuitForge was born from a simple idea: learning electronics shouldn't require downloading clunky, outdated software from the early 2000s, nor should it require purchasing a physical breadboard and jumper wires just to see if an LED lights up.

We believe in accessibility and visualization. A flat, black-and-white circuit schematic can be difficult for students and hobbyists to grasp. By combining a professional-grade Modified Nodal Analysis (MNA) physics engine with WebGL and React, we created an environment where you can pick up a physical-looking component, wire it, and instantly test it in real-time.

The Tech Stack

CircuitForge runs entirely in your web browser. There is no backend simulation holding you back. Our technology includes:

• React + TypeScript: For a stable, type-safe, and highly modular interface.
• Three.js + React Three Fiber: Delivering a high-performance 60FPS WebGL 3D environment right alongside standard DOM elements.
• MNA Engine: A custom real-time solver written in TypeScript capable of solving complex parallel paths and resistive meshes on every frame without dropping frame-rates.
• Gemini AI: The integrated AI assistant operates serverless-ly, intelligently debugging your physical layout for quick insights.
• Firebase: Managing global galleries and user-saved circuits securely.

Our Mission

To democratize electronics education. CircuitForge is free, requires no login to start experimenting, and is built with modern open-source technologies.

Who's Behind This

CircuitForge is built and maintained by Advik, part of LuvaAI. I am a solo student developer building CircuitForge, a free 3D browser-based circuit simulator. I built this because I wanted a hands-on way to learn circuits myself, and it grew from there.

Because I'm learning too, I take accuracy seriously: every simulator behavior and every blog post is backed by real research — datasheets, reference texts, and the sources linked in each article.

While I use AI tools as part of my day-to-day workflow to help write and refactor code faster, every single change is manually tested and functionally verified by me before it ships. I don't just accept AI output as-is. I push regular updates and fixes to keep the simulator running smoothly, and the project's GitHub commit history is the public receipt for this — anyone can go check exactly what was built and when.

If you ever spot something wrong — a bug, a bad explanation, an inaccurate circuit — please tell me. You can reach me at pankaj088@gmail.com. Corrections make this better for everyone using it.
