This is a page from the book with embedded electronics. The circuit was designed in Eagle, produced with the vinyl cutter and glued onto paper.
The tutorial with tips and tricks on how to cut copper with the vinyl cutter can be found here: http://www.instructables.com/id/light-circuit/
For a project at the V2_lab we had to develop a transparent touchpad in textile. For this we needed to create circuit boards that are thin, small, easy to mount on a textile substrate and more or less flexible. To create such a circuit board we started to experiment with cutting copper foil on the CAMM-1 at Protospace fablab.
