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
A graphical Finite State Machine (FSM) designer.
A graphical tool for designing finite state machines and exporting them to Hardware Description Languages, such as VHDL, AHDL, Verilog, or Ragel/SMC files for C, C++, Objective-C, Java, Python, PHP, Perl, Lua code generation.
The DigitalSimulator is your Virtual Electronics Lab, allowing you to design, simulate and output your digital circuit board designs.
A calculation tool for the MC34063
If you ever worked with the MC34063 Switching Controller, you know what a pain it is to calculate all the part values. This tool is an universal tool to help you with this process. You can calculate any standard application, such as step-up, step-down, inverting and step-up-down. PS: I would be happy about any (positive xD) reviews as well as any bugreports, comments or feature requests that you might have!
