Electronics calculator
About the Electronics calculator PCB
Electronics calculator is an open source PCB design by nrwh, published on GitHub under the MIT license. It is a board, with 3 components from 3 distinct parts.
By type, the board carries 2 transistors and 1 test point.
From the project
Web-based calculator for all things electronics.
Web-based calculators for electronics design, published at .
Each calculator gives more than a number:
- choose what to solve for (for an RC filter: R, C or the cut-off frequency) - E-series snapping for resistors, capacitors and inductors, with ideal → chosen → error - the spread of the result across part tolerances - a live schematic, graphs, and a component selection guide - the derivation of every formula (rendered at build time with KaTeX) - a SPICE netlist to copy or download, checked against ngspice in CI
