Modbus TCP,RTU Master Software.
QModMaster is a free Qt-based implementation of a ModBus master application. A graphical user interface allows easy communication with ModBus RTU and TCP slaves. QModMaster also includes a bus monitor for examining all traffic on the bus. QModMaster is based on libmodbus <http://www.libmodbus.org/> for modbus communication and on QsLog <https://bitbucket.org/razvanpetru/qt-components/wiki/QsLog> for logging. Supports both Windows and Linux. For Windows a pre-compiled binary is availiable. It does not require instalation, just unzip and run. Source code is availiable for Windows and Linux for compilation using Qt 5.5.0 <http://www.qt.io/download>. Check out my modbus slave project <http://sourceforge.net/projects/pymodslave/>.

A graphical tool to design a bicycle (s) geometry and derive drawings from its configuration
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
