Sohm — Electrical Engineering Toolkit
Ohm's Law to IPC-2221. In your pocket.
Twelve precision calculators plus a camera-based component scanner — everything you reach for at the bench, in the field, or mid-design.
What's inside:
Ohm's Law solver (V, I, R, P from any two values) + voltage divider
Reactance & resonance — capacitive, inductive, LC resonant frequency
RC/RL time constants, including charging voltage over time
PCB trace width calculator (IPC-2221 standard)
Series/parallel resistor & capacitor combinations
Delta ↔ Wye network converter
LED series resistor calculator
Capacitor stored charge & energy
SMD resistor code decoder
dB power ratio, voltage ratio, and dBm ↔ watts converter
Skin depth calculator with material presets
Battery life estimator
Component Scanner — point your camera at a resistor, inductor, or capacitor to read its value (actively improving; the calculators above are the reliable core)
