# Aaron Lin - Engineering Portfolio

> Aaron Lin is a Boston University mechanical engineering student with an aerospace concentration and a Materials Science & Engineering minor, seeking Summer 2027 internships in mechanical design, aerospace, or product development. Expected graduation: May 2028.

This portfolio is Aaron's first-party account of his engineering experience and project work. It includes CAD, analysis, fabrication, integration, and test evidence. Project pages distinguish individual contributions from team outcomes and state analysis assumptions and limitations. ARGO remains in progress; its current milestones are not completed project outcomes.

## Engineering evidence

- [Project index](https://aaronlin.space/projects/): Current and completed work with links to detailed case studies.
- [Rocket nozzle](https://aaronlin.space/projects/rocket-nozzle/): Completed resin nozzle design and fabrication, pressure-loading analysis, and static-fire integration work.
- [The Deskinator](https://aaronlin.space/projects/ek210-deskinator/): Completed team cleaning robot; Aaron's Arduino navigation firmware and assembly contributions, with a documented final trial collecting 72 of 95 rice grains.
- [ARGO aerodynamic fairing](https://aaronlin.space/projects/argo-fairing/): In-progress aerodynamic concept comparison using ANSYS Fluent and OpenRocket.
- [ME360 Cartesian fishing game](https://aaronlin.space/projects/me360/): Aaron led CAD and mechanical layout for a completed belt-driven fishing game. Its classroom demonstration ran joystick-controlled X-Y motion, an automatic Z dip, magnetic pickup, a rotating board, and all three game rounds.
- [ME360 Cartesian pen plotter](https://aaronlin.space/projects/me360-plotter/): The team developed a single lead-screw stage into a two-axis plotter and produced recognizable square and circular traces using G-code; accuracy and repeatability were not measured.
