ibistools is a small set of command-line tools that aid a PCB designer working with IBIS models. It currently consists of a full IBIS v4.1 parser and an IBIS to SPICE translator. IBIS (I/O Buffer Information Specification) is a standard, human-readable, machine-readable format for publishing IC specifications.
Signal Generator is a laboratory noise/sound generator which can be used to generate accurate sounds in fixed frequency, 2-channels (two frequencies going at once), a sweep-pattern, or in a specified sequence. It is useful when you need to generate a fixed sound for whatever purpose (in the laboratory, for sound effects, etc)
The QConsole class is a custom widget that implements a basic console, written in C++ and relying on Qt. It implements several features and is intended to be inherited from in order to have a "real" console for a specific scripting language, shell, etc. Example implementations for TCL and Python are included.
Resistors is a program to calculate the most suitable E-series resistors for voltage dividers or for generating other values by putting two resistors in parallel. It is especially useful for selecting resistor values for the voltage dividers used in variable voltage regulators. In effect, the voltage in the middle of the divider is known, and you want to achieve a regulated voltage (the top value).
