About Electronics Toolbox

Electronics Toolbox is a growing toolkit of interactive electronics calculators built for engineers, hobbyists, and students. Nothing is installed, nothing is tracked — just open a tool and start calculating.

The current lineup covers everyday circuit tasks: decoding resistor color bands, solving Ohm's law, designing voltage dividers, sizing LED current-limiting resistors, computing RC time constants, and configuring 555 timer circuits.

Every formula follows established electronics engineering conventions. Results are intended for breadboarding, design exploration, and learning — always verify independently before deploying in safety-critical or high-power applications.
