⚡ Inspiration
I am a Computer Science student. Every semester, my friends from the Electronics and Electrical Engineering department come to me with the same problem.
They have an idea for a hardware project — a motion sensor, a smart irrigation system, an Arduino robot — and they spend the first three days not building. They spend three days searching.
Googling wiring diagrams across 15 different websites. Watching YouTube tutorials that use different components than they have. Calculating resistor values manually from Ohm's Law. Writing code from scratch by copying fragments from Stack Overflow. Debugging circuits that look right but do not work for reasons they cannot identify.
I watched my friend Karthik spend an entire weekend trying to wire a PIR sensor to an Arduino for a security light project. The wiring diagram he found online used a different Arduino model. The code had errors. The resistor values were wrong for his LED. He nearly gave up.
On Sunday evening, I sat with him and helped him figure it out. In 45 minutes we had it working.
I knew everything he needed. The problem was access — not ability.
That weekend I started thinking: What if every hardware student had a knowledgeable friend available at any hour? Someone who could look at their project idea and instantly generate the exact wiring diagram, the exact component list, the exact working code — for their specific components, their specific microcontroller, their specific skill level?
No existing platform does this.
Lovable, Bolt, and MeDo build software apps. Fritzing generates diagrams but requires manual component placement. Arduino's documentation assumes existing knowledge. YouTube tutorials are generic, not specific to your exact setup.
The hardware maker community has no MeDo.
Until CircuitForge.

🛠️ How I Built It with MeDo
CircuitForge was built entirely through MeDo's conversational interface — the entire hardware intelligence platform, the interactive wiring diagram system, the camera-based circuit scanner, and the community features — all generated through structured multi-turn conversations with MeDo.
The Build Process
Phase 1 — Foundation and Design System
I began by describing the complete application architecture to MeDo — 6 screens, the dark PCB-aesthetic design system (electric green on deep dark backgrounds, Space Mono for technical data, circuit trace animations), and the core user flow from project description to deployed build guide. MeDo generated the complete full-stack scaffold with all navigation and routing.
Phase 2 — The AI Project Engine
The hardest technical challenge: getting MeDo to build a system that receives unstructured project descriptions and outputs structured, accurate hardware data. I used multi-turn conversations to build:
The natural language understanding layer (extracts microcontroller, components, power requirements, and skill level from any description)
The circuit intelligence system (Ohm's Law calculations, power budget totaling, pin conflict detection, pull-up resistor checking)
The multi-variant generation system (Quick/Standard/Pro versions from one description)
The code generation pipeline (commented, explained, language-specific)
Phase 3 — Interactive Wiring Diagram
The most technically impressive MeDo generation: an SVG-based interactive wiring diagram where components are accurately rendered, wires are color-coded and labeled, signal flow is animated (light pulses travel along wires), and every element is hoverable for specifications.
I used specific MeDo conversation turns to refine the diagram layout rules:
- Arduino always positioned center-left
- Input components (sensors) on the left
- Output components (LEDs, motors) on the right
- Right-angle wire routing only (standard practice)
- Bridge symbols where wires cross without connecting
- Filled dots where wires connect
Phase 4 — Circuit Scan & Fix
This feature required the most creative MeDo prompting. I described the camera overlay system, the component detection logic, the annotated result display, and the health score calculation — then used MeDo's visual editor to refine the scan results UI until the component bounding boxes, annotation overlays, and fix guide cards felt like a professional diagnostic tool.
Phase 5 — Polish and Mobile
The final pass focused on Bench Mode — the mobile-specific layout for physical building — and the complete navigation system with back buttons on every page, undo functionality in the builder, and smooth circuit-trace-drawing page transitions.

🚧 Challenges I Faced
Challenge 1 — Accurate Circuit Diagrams
Electronic circuit diagrams follow strict conventions — wire routing, component symbols, pin labeling. Getting MeDo to generate diagrams that are not just visually clear but technically correct required extensive iteration. I spent multiple MeDo conversation turns defining exact layout rules: wire colors, routing conventions, connection dot placement, bridge symbols for crossing wires, and component positioning logic.
Challenge 2 — The Circuit Scan Feature
Teaching MeDo to build a camera-based circuit diagnostic tool was the most complex prompt engineering challenge. The system needs to: request camera permission, capture or receive an image, pass it to the image analysis plugin, interpret the results as circuit-specific feedback, overlay annotations on the original photo, calculate a health score, and generate specific fix instructions — all as one coherent flow. Each layer required its own dedicated MeDo turn.
Challenge 3 — Hardware Knowledge Accuracy
Unlike software, hardware errors can damage physical components. A wrong resistor value burns an LED. A reversed power connection destroys a microcontroller. I had to carefully prompt MeDo's LLM to always include safety warnings, always show Ohm's Law calculations, always check power budgets — and to use conservative component values when uncertain.
Challenge 4 — Making Complexity Simple
The target user is a beginner student who gets overwhelmed easily. CircuitForge generates a lot of technical information — component lists, wiring diagrams, code, troubleshooting guides — and it all needs to feel approachable rather than intimidating. Every MeDo polish turn focused on simplifying language, reducing visual clutter, and ensuring the most important action was always the most obvious thing on screen.
Challenge 5 — Mobile Bench Mode
Using a hardware project guide on a phone while physically building a circuit is fundamentally different from reading it at a desk. The screen needs to be readable with one hand while the other holds a wire. Buttons need to be tappable with dirty fingers. Steps need to be large enough to read across a workbench. Getting MeDo to build a genuinely workbench-optimized mobile interface required a dedicated prompt turn describing every specific constraint of the physical building context.
📚 What I Learned
The most important insight: hardware builders are underserved by AI not because the technology cannot help them — but because nobody has built the right interface between hardware knowledge and conversational AI.
CircuitForge taught me that MeDo's full-stack generation capability extends far beyond typical web apps. By carefully describing technical domains that require specialized knowledge — electronics, circuit design, embedded programming — MeDo can generate tools that previously required a team of domain experts to build.
I also learned that the best AI tools do not replace human knowledge — they democratize it. Every insight CircuitForge provides is knowledge that exists somewhere — in textbooks, datasheets, tutorials, and the heads of experienced engineers. CircuitForge makes that knowledge available to the student sitting alone at midnight trying to finish their project.
The hardware knowledge gap is not permanent. CircuitForge closes it.

💬 A Final Thought
My friend Karthik eventually built his security light. It took a weekend of frustration, several burned LEDs, and one friend who happened to know the answers.
Not every student has that friend.
CircuitForge is that friend — available at midnight, never frustrated, always accurate, and ready to explain anything as many times as needed.
For every student who gave up on a hardware project because they could not find the right wiring diagram — CircuitForge exists for them.
