An interactive guide to the three main full-wave EM solvers. See the real mesh each solver uses on 20 devices, learn how each one works, and pick a solver and a tool for your problem. Runs in the browser.

Five RF and microwave calculators that show the physics: skin effect, coax, microstrip with a live field solve, rectangular waveguide modes, and path loss with a link budget. Each one checks itself against published values. Runs in the browser.

Learn to write Maxwell's four equations from memory in about 15 minutes. Interactive fields show what each law means, then you build and recall each equation. Runs in the browser.

A Smith chart game and a guided tutor. Solder parts onto a bench, watch the impedance move on the chart, and learn matching from the Smithy. Runs in the browser.

An interactive bench for RF and microwave fundamentals. Change a part on the left and watch S-parameters, Smith charts and load lines respond on the right. Runs in the browser.

A web app for visualizing personal cash flow with Sankey diagrams—upload transaction CSVs, filter by month, and save/load your data.
