so is that a pcb as well? printed circuit ball? :-P On Jan 22, 2009, at 3:48 PM, John Doty wrote: On Jan 22, 2009, at 11:02 AM, DJ Delorie wrote: There's no such thing as a one-sided board.

gEDA-user: Fritzing was: Re: geda-user Digest, Vol 32, Issue 92
Hi -- One thing. Fritzing's close tie-in with Eagle is, um, out of tune for an open-source/open-hardware project IMO. But that's not my decision to make, and we're happy to see you guys are contacting us (a real open-source EDA project). I agree with you. Since our summer restart, we have ditched all the dependencies on Eagle and now have our own simple but functional PCB view. We may eventually support an export to Eagle option but our core goal is a fully FLOSS production process. Great! I guess I was more familiar wtih the old Fritzing. So... Is the footprint structure documented anywhere? (I admit I haven't looked.) Docs... heh. Who has time for docs? Actually, I should work on that. If you guys are interested, then I will try to put something on our web site explaining the SVG formatting. Basically, all the paths for each layer are stuck in a group which is tagged with the id for that layer. At the moment we only support single sided boards but we will need to add the bits on the back of the board at some point as well. *chuckle* Right now, PCB doesn't quite support single sided boards. (Stuart waits for others to explain how he is wrong again) Anyway, yes, putting something on the web would be good. May I recommend a Fritzing wiki with design info? Even if it's only one paragraph (Not that we make our design info easy to find. I mean, besides read the source ) Anyway, we have an open Linux Fund project to upgrade gEDA/PCB so that it does better things with footprints and layers. If enough people donate to that fund, then we anticipate some real big improvements to PCB. Therefore, now is a good time to have a discussion about what info is needed in a good footprint. Seeing your info -- even just a drawing or a paragraph -- would be very useful.

Boards always have at least two sides, unless you've invented a mobius pcb. Therefore, pcb supports two-sided boards with copper only on one side, which is what people actually make. :-) ___ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user

Well, with flexible PCB's it would be possible, but given the looks I've gotten from some of the mech. E's and manufacturing E's I've worked with in the past, I suspect the suggestion would not be welcomed. :) -dave ___ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user

We have Cairo underpinnings all ready for coding SVG stuff. (I'm not ready myself to code ti though.).

This reminds me of two facts of saturation magnetic recording on rotating (disc) media. You can only have an even number of transitions around a track. Also, as much as test engineers would like to both surfaces have to be spun at the same rpm.
