Lhonge worked on the masa-umich/mcnugget repository, focusing on automation and control systems for ignition sequencing in embedded hardware. Over three months, Lhonge delivered a series of Python-based features that improved reliability, safety, and observability in ignition and autosequence workflows. The work included refining timing logic, implementing robust monitoring with sliding window confirmation, and automating torch ignition processes by removing manual prompts. Lhonge also enhanced maintainability by standardizing naming conventions and updating simulation components. The engineering approach emphasized iterative development, thorough code commenting, and cross-team collaboration, resulting in well-documented, production-ready control software with reduced operational risk.

February 2025: Delivered the Torch ignition automation refactor for masa-umich/mcnugget. Consolidated and cleaned the autosequence ignition workflow by removing interactive prompts to enable full automation. Introduced a dedicated torch_ignite function, added abort handling for safing during interruptions, simplified monitor logic, updated the ethanol tank simulation, and standardized naming for valves and sensors to improve consistency and maintainability. The changes position the project for safer, more reliable deployments and faster iteration cycles.
