Calculating resistor values with full hands is a pain. That's why I built VocalOhm a fast, voice-powered calculator for resistor color codes, SMD codes, and parallel circuits. Just speak (e.g., "brown black red", "smd 123 " or "100kohm") to get instant results without putting down your tools. Built as an ultra-lightweight Web App, it works entirely offline on your device (local voice recognition). Zero cookies, no sign-ups, and no tracking - just a privacy-first utility for hardware makers.
