A circuit simulator with graphical user interface (GUI)
Qucs is a circuit simulator with graphical user interface. The software aims to support all kinds of circuit simulation types, e.g. DC, AC, S-parameter, Transient, Noise and Harmonic Balance analysis. Pure digital simulations are also supported.
Simple and intuitive 2D vector drawing for electronics and not only.
A multiplatform vector drawing program with a complete library of electronic symbols. Schematics and drawings are stored in a very compact text format. There is no netlist concept behind the drawings (so no simulation, and this is a choice) but this allows a great graphical flexibility and ease of use, making FidoCadJ the perfect tool for exchange sketches in forum and newsgroup discussions with a few clicks. Drawings can be exported in several graphic formats, such as pdf. Follow the development live on Twitter: https://twitter.com/davbucci
TkGate is a event driven digital circuit simulator with a tcl/tk-based graphical editor. TkGate supports a wide range of primitive circuit elements as well as user-defined modules for hierarchical design.

Gerber2eps - A small program for converting Gerber RS-274D files to Encapsulated Postscript (EPS).
Open firmware for Honeywell Rondostat HR20 radiator thermostats
The sigrok project aims at creating a portable, cross-platform, Free/Libre/Open-Source signal analysis software suite that supports various device types, such as logic analyzers, MSOs, oscilloscopes, multimeters, LCR meters, sound level meters, thermometers, anemometers, light meters, dataloggers, function generators, power supplies, GPIB interfaces, and more.
PikLoops is a simple KDE program used to generate assembly time delays for Microchip microcontrolers using Microchip instructions.
Virtual electronic circuit simulation with JAVA based schematic entry and wave viewer, based on (Berkeley) SPICE, for any OS/Server/Browser configuration. Due to missing public feedback for over one year its status is set to INACTIVE (1/2004) - sorry.
upf2cpf is a cool command line tool which will takes in a UPF(Unified Power Format) and will convert it to a CPF(Common Power Format).This tool is very useful for Chip Design Engineers, who want to feed the power related info about the RTL in UPF/CPF.
"DSO" is a Digital Signal Oscilloscope. My DSO will be connected via the USB to the PC. All software to operate the DSO is developed within this project.
An Open Source Parser Library for parsing Verilog, System Verilog, EDIF and VHDL source files.
PCB-Tools is a system independent, a Java programmed Eclipse-RCP application for developing circuit diagrams and printed circuit boards. It uses Eclipse Graphical Editor Framework (GEF) to draw diagrams and layouts.
Digital circuit simulator with an own IC-scripting-language, programmed in Visual C++ 2003.net, currently only available for Windows. Major technical goals: Creation of a bugfree interface and effective signal simulation. All config-files in txt-format.
With eparts, you can manage your stock of electronic components. You can create and manage projects, part lists, suppliers, buying lists etc. and import projects from EDA tool 'kicad'. It's written with Ruby on Rails.
Home Automation Server onewire is a small Server witch is able to interact with a onewire Network. With an simple XML-File you are able to configure the functionality of the ow-devices. Furthermore you can query server by a simple terminal like telnet.
The sigrok project aims at creating portable, cross-platform, Open-Source logic analyzer software that supports various hardware products. The sigrok+ project is a fork of the great sigrok project, with added support for oscilloscopes.
tkCybernetics is a small grafical tool for rapidly setting up simulations of simple cybernetic systems. It was designed for didactic purpose but might be useful for the quick test of some circuit too.
