gEDA-user: Greetings from Fritzing
Hello gEDAns, I am one of the developers of Fritzing, a simple FLOSS EDA made for less technical (non-engineer) users. Our project is young but we have been posting frequent releases since November. I am also a gEDA user since 2005. I want to thank all the developers for producing such a powerful piece of software. Quite a few ideas (but no code) in Fritzing were based on your designs. Introductions aside, I was hoping to start a dialogue between our groups. We see our project as fitting into the EDA world in a different space from gEDA. Most of our target audience have limited experience with electronics and are interested in realizing small, low-complexity prototypes. However, as our software is limited (intentionally) in scope, some users may reach a stage where they need the more advanced EDA features of a package like gEDA. Right now, I'm working on a gEDA-PCB footprint import component that converts gEDA footprint files to our internal SVG based files. In the long term we would be interested in supporting some sort of export path so that users can export Fritzing projects and continue working on them in gEDA. Feel free to try out our latest builds, give us feedback, tips, gripes, etc. And we are totally open to any kind of collaboration. http://fritzing.org best, Brendan Howell ___ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user

Hi -- I am one of the developers of Fritzing, a simple FLOSS EDA made for less technical (non-engineer) users. Our project is young but we have been posting frequent releases since November. Yeah, we're aware of the project. I pestered you guys about a year ago to get invovled with gEDA. Welcome, and congratulations on getting Fritzing off the ground! Introductions aside, I was hoping to start a dialogue between our groups. We see our project as fitting into the EDA world in a different space from gEDA.

However, as our software is limited (intentionally) in scope, some users may reach a stage where they need the more advanced EDA features of a package like gEDA. Yeah, the protoboard paradigm for doing a design is very different from the traditional PCB design flow (which is one thing gEDA tries to do). It's an interesting approach for electronics newbies Reading your bulletin board, I see many people who like the interface a lot. Getting a user interface to be natural and intuitive is very difficult! (Particularly in an open-source project) 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). Right now, I'm working on a gEDA-PCB footprint import component that converts gEDA footprint files to our internal SVG based files. In the long term we would be interested in supporting some sort of export path so that users can export Fritzing projects and continue working on them in gEDA. Very cool! Being able to convert gEDA/PCB footprints - Fritzing footprints (both ways) would be very nice. A big win would be that one could use any SVG drawing program to create the footprints, and then convert to a gEDA/PCB .fp file. The question here is: What is the structure of a Fritzing footprint? That is, a footprint assumes a certain layer structure. For example, a through-hole footprint assumes you have top silk, top mask, paste and metal, some clearance structure for inner layers, and then bottom silk, mask, paste, and metal. Also, one might also want to provide a keepout layer and also other layers which I have probably forgotten. So... Is the footprint structure documented anywhere? (I admit I haven't looked.)

Hello, I previously generated a pcb board. then, I had to make a lot of changes. So, I copy the previous .sch files into new ones, and created a new project with the new files. Now, when I generated the new pcb (gsch2pcb) I lost all the benefits of my previous pcb (I mean, I need to restart form scratch). How can I generated the new.pcb file including my changes ?

So you can edit a copy of your pcb to get those matching before running gsch2pcb. Sometimes a text editor is easiest for the footprint part of that, but just use pcb to see the topology that compares to your new schematic and redo the refdes's in pcb.

gEDA-user: Question about footprints in pcb
I'm a little unclear about the mask dotted line of the pad command. In the How to Create Footprints document it says this value is the width of the solder mask relief. Is this value the distance from the pad location line to the center of the clearance measurement? If I double the mask how does it affect the diagram in the document? I'm also wondering why the distance from the pad to other conductors on any plane (the clearance) is the clearance value divided by two and not just the clearance value. Finally, if I'm laying out these boards to be made at home what are good values for clearance and mask?

Re: gEDA-user: Question about footprints in pcb
I'm a little unclear about the mask dotted line of the pad command. The solder mask size is specified as its own width, just like the copper pad's size is its own width. I'm also wondering why the distance from the pad to other conductors on any plane (the clearance) is the clearance value divided by two and not just the clearance value. The copper clearance is specified as the amount to add to the pad size. So it's a total for both sides Finally, if I'm laying out these boards to be made at home what are good values for clearance and mask? Depends on your process. For toner transfer, 10 mil line/space rules are normal if you're experienced (up to 20/20 for TT newbies), that means clearance will always be 20 mil or more (10 on each side). Most home-fabs don't do masks, but I set mine to result in a 3 mil gap between copper and mask, since that's what most commercial fabs want. The MinMaskGap() action can fix up any stragglers for you. ___ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user

This is a partial work-around for some cases, but I would agree with the original assertion that something is amiss with the eps export. For some documentation that I'm writing, I need a vector drawing of my circuit board *as it appears*, i.e., with silk, pins, and vias -- but not tracks-- visible. (Kinda like ben/photo mode, but in vector.) So far as I can tell, pcb is quite incapable of exporting an eps drawing like that, even though it's trivial to display just those parts by clicking which layers are visible. Since this is considerably different from what would be expected by a reasonable observer, I would indeed classify it as a bug-- either in the function executed or in the label, because it cannot generate an eps as shown. The method that you describe above-- exporting a file with some parts invisible-- can be used to make the tracks invisible as well. I can use that method to produce a fake version of what I need, with the tracks in white but the silk, pins, and vias visible, but those white tracks are *still there* and actually do get in the way of what I'm doing. I did find a genuine but invasive work-around that can generate the output that I wanted, which *may* also help with the pad-omission problem as well. Make a duplicate pcb file for documentation/output: circuit-doc.pcb Open the circuit-doc.pcb file in a text editor, delete the entire contents of all layers with tracks on them. Pins and pads should not be affected, since they are stored as parts of the element. Save and then open the modified file in pcb. Make all layers visible and export eps.

Picking gschem from the popup menu system doesn't work either. I know that this is a bit off the beaten track, but maybe someone has seen this before. I'm stumped. Yes, if you screw your configuration files up you can make gschem fail with no GUI warnings. Try running gschem from a terminal window and have a look at the output -- it should give you hints about what's going wrong. This is a known problem, and something that we're planning to address in future releases.

Re: gEDA-user: PCB printing under Windows?
How do you get the calibration page to print? There is no PostScript output option for that. Calibration request takes you directly to lpr. Ok, that will slow you down a bit :-) ___ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user

Re: gEDA-user: Fritzing was: Re: geda-user Digest, Vol 32, Issue 92
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.

There's no such thing as a one-sided board. 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 ___ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user

Re: gEDA-user: pcb bug: EPS output omits pads

Ack. The as-shown not printing as shown option made me feel uneasy too. Anyway, I filed a feature request Better Control of Postscript Output http://sourceforge.net/tracker/index.php?func=detailaid=2528814group_id=73743atid=538814 I wish I could specify print properties according to layer _and_ object type.
