How I approach rapid prototypes

In this 15-minute walkthrough, I show the research and planning behind a working prototype. I also explain how I used AI tools during the build. I built the core demonstration in two days after the initial planning work.

The goal is to learn quickly without skipping the research & planning.

An independent conceptual demonstration inspired by the Artemis II launch. It uses simulated data, is not affiliated with NASA, and is not clinically validated.
