General Remarks

The catalog of symbols and footprints presented here is self consistent. That is, the default footprint attribute of a symbol points to one of the footprints given in the footprint section.

Note: All my symbols and footprints are licensed GPL 2 or GPL 3 for distribution, and unlimited for use. See http://www.gnu.org/licenses.gpl.txt for the details

New Project Script

new_geda_project.sh is a little convinience script to starting a new geda project. When given a project name, it creates a simple directory structure and populates it with some config files (gafrc, attribs). In addition, it copies a documentation template in lyx format to the directory.

Scripted pcb layout export

The bash script layoutdruck.sh uses actions on the command line of pcb to produce a set of printouts for use in documentation. These include a multi page PDF with top and bottom layout, each with values and with refdes. The layout can be spread between several sheets for large layouts.

In addition photo realistic PNG export of top and bottom side is produced. A drop shadow is added to the PNG to make the image even more photo realistic.

Note, there is a bug in pcb that prevents the execution of actions when printing from the command line. This script needs a bug patch of pcb not yet applied to the distributed version of pcb.

Convenience Scripts

  1. : Emits the footprint file given on the command line with the value of all pin and pad names set to the value of their number. Requires awk.

Symbols

The symbols in this sections are designed according to the following design criteria:
  1. they contain a default footprint attribute.
  2. the footprint attribute is visible on the schematic and printed with a smaller font size than the refdes and the value of the symbol.
  3. they contain a human readable description
  4. power pins of integrated circuits are split off to a seperate power symbol
  5. pin numbers are hidden, if they obeye a generally accepted standard

Title Blocks

These title blocks include attributes for date, author, project name and page number.

    I don't do much digital electronics except for some basic 74xxx components...

    power symbols

    Misc

    block

    These are blocks of subcircuits I frequently use. They contain some of the above symbols. Add them to a circuit with the option "Include-as-individual-objects" checked. See the wiki for details. For some blocks preview does not work correctly because I did not embed the symbols. Consequently, there is no way for gschem running on the geda-symbols server to find the symbols contained in the blocks. However, these blocks will work, if you have installed my symbols locally.

    Footprints

    template pcb

    The template.pcb may be used to start drawing footpints with the pcb GUI. Layers and sizes are set to reasonable default values.

    generic SMD

    These footprints are meant to supersede the ones from the default library. They are designed to meet the requirement of densely populated boards with too little space to place the refdes or value between the components. Therefore the text is placed inside the frame. Pad size is sufficient to hand solder the parts.
