Built for Engineers
Free calculators, converters, scripts, and downloadable project files from the EFury Labs workshop.
Quick Calculators & Converters
Ohm's Law Calculator
Calculate voltage, current, resistance, and power. Enter any two values and get the rest instantly.
Hex / Binary Converter
Convert between hexadecimal, decimal, binary, and ASCII formats. Essential for embedded debugging.
Resistor Color Code
Click the bands to read a resistor, or type a value to see which colours to look for.
Voltage Divider Calculator
Find Vout from R1 and R2, or pick R2 for the voltage you need — with the nearest standard resistor.
Power Dissipation Calculator
Resistors, linear regulators, and MOSFETs — with junction temperature and a heatsink check.
Unit Converter
Engineering prefixes, capacitor codes, dBm ↔ watts, temperature, and mm / mil / AWG.
