Circuits contains schematics and layouts for circuits related to stompboxes. Most are effects that have been designed by others, including replications of such classic stompboxes as the tubescreamer. Each circuit post comes with a set of files with links that appear in the left-hand sidebar. For building a circuit, there are files containing
- the schematic,
- a layout,
- a PCB image for etching, and
- a list of parts.
For the simpler circuits, a layout can also be applied directly to perfboard because all layouts restrict the component pads to a 0.1″ grid. Circuits with many components may have trace routes that are difficult to use with perfboard. For convenience, all of these files have also been wrapped inside a PDF project file.
In addition, the CAD files for Eagle software appear in a zipped project file. These files were used to produce the images for the schematic, layout, and PCB. They can be loaded into the freeware version of Eagle for redesign. As simple examples, one can change
- the width of traces,
- the diameter (and sometimes the shape) of pads,
- the packages of components, or
- the locations of components (for more or less space)
Alternatively, a completely new layout can be constructed from the schematic.
