The problem
Useful hardware guidance must be complete, consistent, and reviewable
Language models can produce plausible hardware recommendations while omitting constraints or introducing inconsistencies across components, pins, power, and connectivity. Engineers need structured artifacts and explicit checks, not an untraceable block of generated advice.
The system
Generation followed by deterministic engineering checks
The workflow separates interpretation, structured generation, validation, and presentation so that every handoff can be reviewed before it is used.
What I built
A safer path from prompt to engineering artifact
Designed a guided requirements workflow for supported ESP32 boards, sensors, interfaces, and operating constraints.
Produced structured component selections, bill-of-material details, pin assignments, netlists, and power-budget information.
Added deterministic validation and fallback behavior so the workflow does not depend on a model response alone.
Included unsupported-request handling and review cues that make scope and uncertainty visible to the user.
Built a Streamlit interface that keeps inputs, validation status, and generated engineering artifacts easy to inspect.
Maintained a public repository and live prototype so the implementation can be reviewed directly.
Quality and evaluation
Validation is part of the product, not a final decoration
Checks cover structured output, supported hardware scope, pin and component consistency, and deterministic fallback paths.
The site presents this as a prototype for engineering review. It does not claim that generated artifacts replace professional electrical validation or fabrication checks.
