StripCAD - A circuit editor for stripboards

StripCAD is a free program for stripboard (a.k.a. “Veroboard”) circuit CAD running under Windows and Wine/Linux.

StripCAD is intended to accelerate prototyping electronic circuits. The fundamental approach is (1) unify circuit schematics and circuit layout, and (2) to minimize soldering by mounting components vertically and using horizontal strips for interconnections. Both I and my engineering students at Lund University have tested it extensively and it has relatively few bugs.

A typical workflow is as follows:

  1. Simulate your circuit, e.g., with LTspice.
  2. Draw your circuit with StripCAD. Use ‘z’ to zoom - pixels are small on today’s screens!
  3. Print the circuit as a PDF with StripCAD.
  4. Print the PDF on paper.
  5. Cut out a stripboard chunk of matching size. Heating it by a hair dryer first helps.
  6. Stick the paper schematic/layout to the top/component side of the piece of stripboard so that the dots match the holes.
  7. Cut the traces between the holes on the bottom/copper side of the board where indicated by ‘x’ on the schematic. This requires some practice, but becomes easy when you get the hang of it.
  8. Solder components to the board. Cut off surplus wiring and save it to be used as jumpers.

I started writing this program a very long time ago (~1986), so the source code is horrible, but on the other hand, it runs very well on old and simple hardware. It had its main boost when I developed it for the computer mechatronics course at Lund University 2003-2007.
