Resistor colour code calculator
TypeScript11 GitHub starsresistor-color-calculator
A small web utility that turns a resistor's colour bands into its resistance value and tolerance — pick the band colours, read the answer.
Why it mattered
Built for my own electronics tinkering, because memorising the colour code is a chore and looking up a table mid-build breaks the flow. It's stayed useful to other people for the same reason.
