A simulation of a NYC Transit Authority train traveling by automatic signals with working stop arms. Working circuit drawings show how the signal system relays function while the train passes over track circuits.

Rimu PCB is an easy to use, cost effective electronic printed circuit Bord (PCB) layout application. Features: Export Gerber RS274X and Excellon NC drill. Import ASCII netlist. Design rule checking. Multiple Undo / Redo.

The HAM Intelligent Calculator, also called HAMIC, is designed to aid HAM radio operators perform a number of calculations. This includes simple circuits (e.g. resistors), complex circuits (e.g. L networks), or other calculations (e.g. SWR).
