Hey everyone, maker here 👋
I built this because I kept re-deriving subnet math and voltage drop formulas by hand, or landing on calculator sites buried in popups before I could even see the result. It started as a single voltage drop calculator, and grew into a small directory of tools as I kept running into the same repetitive math in different parts of network and infrastructure work.
Happy to answer questions, and genuinely want to hear which calculator is missing an edge case, or what tool you'd want added next.
