Re: gEDA-user: Using polygons for creating a ground plane by hand
Use the 'q' key to change pins/pads from round to square and back. Oh okay: thanks. I guess I'd better go ahead and convert all of these vias and my silk layer stuff to elements first. Yup. Okay then. I know what to do about the ground plane now. Thanks much, Jeremy ___ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user

gEDA-user: Trick to add sick text to PCB
First, I'd like to thank the developers of PCB and gEDA. These tools are VERY nice, and I'm glad someone has made this software for linux. Thanks for the work and all of the support. If anyone is interested, here is a little trick to add some text in the silkscreen of your PCB layout. The text can say anything you want and can be any size. The trick is: in both your schematic and layout, add a component which has no pins and doesn't connect to anything. The text should be contained in the RefDes of the footprint and will be included as silkscreen on the layout. I've got a design on sourceforge that's a good demonstration of this. The design is at http://sourceforge.net/projects/wireless-usb The schematic symbol should be called "text.sym" and contain:v 20061020 1T 1700 2100 8 10 1 1 0 6 1refdes=TEXT-HERET 300 2100 9 10 1 0 0 0 1silkscreen_textT 300 2100 5 10 0 0 0 0 1footprint=text_footprint The footprint file should be called "text_footprint" and contain:Element[0x0 "text" "" "" 0 0 -5830 -9846 0 110 0x0](ElementLine[25600 9450 -25600 9450 800])Of course there are hundreds of ways to modify this code and get the same result... I am using an old version of PCB from the debian database, so this function may have been included in newer releases. I've noticed in the lists, that a number of good functions have been added since debian grabbed their version. Hope people find this useful.Jason ___ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
Re: gEDA-user: Using polygons for creating a ground plane by hand
Oh, maybe I should clarify: The pcb I am recreating has components with square pads: that is what I am trying to do. I have done this by placing a rectangle around a via in the component layer and also in the solder layer. I am using the component layer as my "top" layer and the solder layer as my "bottom" layer. I am then eliminating the clearance between the via and the copper. Is this the wrong way to do this? Also, if I wanted to have this manufactured and I only wanted to pay for a two layer board (after all, the original pcb is only two layers), would I only want to use the "component" and "solder" layers for the board? This would mean I would place the bottom-side traces in the groundplane (with some clearance, of course)...is this correct? I am still a little confused. Thanks a lot, Jeremy ___ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user

Re: gEDA-user: Using polygons for creating a ground plane by hand
Jeremy, Create a polygon around your via. Make sure you have the polygons layer active. Now use the therm tool to click on the via. Steve M.

Re: gEDA-user: Using polygons for creating a ground plane by hand
Ok, so the solder mask is a coating, and if I choose I could simply order a board without one. I suppose the advantages would be that it (obviously) keeps you from soldering where you shouldn't, and also keeps the board clean looking and prevents corrosion. And I suppose that since I've already made all of the elements, it wouldn't be too difficult to ensure the spacings between the pins and then make them into elements. If it's the lesstif version, it's in the Tools menu. In the GTK version, you can use the buttons on the left. Ok. Is it the THRM button? If so, I can't get it to work. I click it, and it gives me a small black symbol resembling Germany's Iron Cross (if you're familiar with that symbol). If I place this over a via and left click, right click, or shift (and left click), nothing happens. I will see if I can find out about this tool in the documentation, but do you have any idea what I might be doing wrong?

Re: gEDA-user: My footprint generator
> So, when people use footprints with .fp in the name you actually use > footprint=SMDIP4.fp ? Yup. I added the .fp for the web server, we haven't fully migrated to it yet.
