Experiments
Change the inputs and inspect each response: AC load-flow voltages and branch flows, Mandelbrot zooms, or a PID step response. Each experiment keeps its controls beside the resulting view or chart.
Power Systems
AC Load Flow Solver
An interactive AC load flow solver for editing one-line models and inspecting bus voltages and branch flows.
Fractals
Mandelbrot Explorer
A Mandelbrot explorer with arbitrary-precision viewport math, progressive rendering, and URL parameters that set the initial view.
Control
PID Controller Simulator
Fixed-step PID simulation for trying gains and seeing rise time, overshoot, oscillation, and settling behavior.
