UncertaintyCalc
A practical tool for simplifying measurement uncertainty calculations, built during a hackathon in summer 2025.
Context
UncertaintyCalc was built during a hackathon in summer 2025. Measurement uncertainty is one of the harder ideas in metrology to communicate. The arithmetic is not difficult, but assembling a defensible uncertainty budget (identifying the contributions, combining them correctly, and reporting the result honestly) trips up people who are otherwise comfortable with their instruments. UncertaintyCalc grew out of more than forty years working in temperature calibration, where I saw the same gaps appear again and again.
What I built
A web application that walks through an uncertainty calculation in plain terms, so the figure at the end is one the user can stand behind rather than one a spreadsheet produced quietly in the background.
Role
Designer and developer. Conceived, designed and built as a solo hackathon project.
Outcome
Live at uncertaintycalc.com.
What it shows
Domain knowledge applied to a genuine working problem, and a preference for tools that make a difficult idea legible rather than hiding it behind a result.
