Strippy is an automated Stripboard placement tool, implemented in Python.

Strippy is a work-in-progress, and highly experimental. Currently only a few component types are supported, and it can solve very small problems in a reasonable time frame.

Currently netlists, board parameters, and components are defined in Python, which are then passed into cli.main which parses common command line options and then solves the given problem.

Note: All of these examples require the repository root to be in the PYTHONPATH.

Placement of a resistor on a 1x2 stripboard:

examples/1-resistor.py --svg output/1-resistor.svg

Here is the output:

The resistor is shown as a green rectangle. Note there are two output images because of the two possible orientations of the resistor. The numbers indicate the components' terminal numbering.

Placement of a 4-pin DIP package, with resistors joining adjacent pins:

examples/dip2.py --max-drilled=2 --svg output/dip2.svg

This example requires --max-drilled to be passed to find solutions, to allow the holes between the pins of the DIP package to be drilled.

Here is the output:

Again, there are two possible solutions. The horizontal grey lines indicate the conductive traces on the stripboard, and the red crosses indicate which holes should be drilled out (breaking the conductive trace).

Placement of a 4-pin DIP package, with resistors joining opposing pins:

examples/dip3.py --first-only --max-drilled=2 --max-jumpers=2 --max-jumper-length=1 --svg output/dip3.svg

Note that max-jumpers=2 and --max-jumper-length=1 is passed to allow at most 2 jumpers (with a maximum length of 1) in the solution. --first-only is passed so that only the first solution found (of which there are many) are displayed.

Here is the output:

The thick lines indicate where jumpers should be placed.
