gEDA-user: Segfault in pcb when exporting (latest branch)
With the current git HEAD, pcb segfaults as soon as you click 'png' in the export list. Can anyone confirm this isn't just me? Assuming it is an actual bug, I have filed a report and attached a patch at https://bugs.launchpad.net/pcb/+bug/769336 -- Andrew Poelstra Email: asp11 at sfu.ca OR apoelstra at wpsoftware.net Web: http://www.wpsoftware.net/andrew/ ___ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user

/*xx I'm going to go out on a limb and state that I refuse to support non-flat layers :-) [1]http://www.allflexinc.com/origamiflex.shtml Supported or not these things are worth taking a look at just for the strangeness if noting else: " Origami Flex Circuits Take Shape at All Flex Ok, that's just too damn cool. It looks like lots of fun. :) */xxx There is not much to support, and they are easy to work with. I worked at a Flexible PCB hose for a couple of years, and all of the ones shown are single or double sided boards. You design it like a normal PCB, other than you make a much more intricate route pattern for the outline layer than a rectangle. You leave areas to make the folds or bends (don't place vias or components in those areas), and then you can crease them after assembly for a tight permanent bend, or leave them as is for an open/close movement (like the display cable on a laptop lid). If you need certain areas of the board to be rigid, you can mount it onto a sheet of Aluminum (adds stiffness and thermal dissipation) or take some FR4 hardboard to make a stiffener that is glued onto a small area (non conductive). Really the only layers you would need to add to your project are: A layer to indicate fold lines for bend locations (if needed) A layer for stiffeners (If needed) A layer for internal cutouts, made moments before the outline route (if needed) The only real challenge is for you to design a 2D object that will bend and flex to fit your 3D application ;-) Andy Miner References 1. http://www.allflexinc.com/origamiflex.shtml ___ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
