Rocketry
This is me when I play.
I still get a thrill from launching an application or sending a custom rocket skyward. Both demand careful design, simulation, integration, and operational readiness.
Amateur rocketry and software engineering have taught me the same lesson: success is built in the integration. Ideas, design, simulation, CAD, 3D printing, materials, electronics, weather, safety, checklists, teamwork, telemetry, testing, and judgment all have to work together. None of the parts wins alone. The same is true for teams.
Fun belongs in the system too. It is fun to solve problems, to test an idea, to figure out how to loft a big rocket higher than expected, or help a team make something hard finally work. Fun does not make the work less serious. It makes the work worth staying with.
The successful project shelf includes scratch builds like Mega Der Red Max, a Level 1 Goblin, Project X - The 2nd Level, and the road toward Level 3 with The Hollow Wind, a 7.5-inch LOC/Precision Skinwalker project.
Fabrication Building complex parts into a complex, interdependent system means every material, fit, fastener, print, and assembly choice has a job.
Simulation & Ground Testing Simulate the mission, test the parts, rehearse the full system, and make the real launch the final low-risk step.
Instrumentation & Telemetry Good data proves performance, exposes problems, and turns uncertainty into clear, actionable outcomes.
Risk & Recovery Enumerate failure modes, set acceptance criteria, and plan the abort, rollback, or recovery path before the button gets pushed.
Iterative Design Repeated, measurable experiments beat one high-risk bet. Build, test, learn, improve, then fly again.
