gEDA-user: gschem gnetlist problem
Hello all, I am trying to use gnetlist for the first time to create a Bill Of Materials (BOM) from my schematic. This is a test case of mine to come up with a procedure to do this. I keep getting the following: 536:$gnetlist -g bom xx.sch Loading schematic [/home/gherr/projects/vds160/original/hardware/dac/docs/xx.sch] Backtrace: In current input: 1: 0* [bom output.net] In /usr/local/share/gEDA/scheme/gnet-bom.scm: 37: 1 (let ((port #) (attriblist #)) (bom:printlist (cons # attriblist) port) ...) 40: 2* [bom:parseconfig ... 40: 3* [open-input-file attribs] In unknown file: ?: 4 [open-file attribs r] unnamed port: In procedure open-file in expression (open-file str OPEN_READ): unnamed port: No such file or directory: attribs It produces essentially the same error when using bom2. Of course, the output.net file is empty. What is this attribs file it seems to be looking for and not finding? Am I supposed to create this file? If so, where can I find a description of it? I have looked at the manpage, the gnetlist User's Guide, did some searching on the web for this error (gnetlist [open-file attribs r] ), and looked at the distribution for more documentation, all to no avail. For the record, I am using gEDA 1.6.2.20110115, KDE 3.5.10, Slackware Linux 12.2 (k2.6.27.7). I am not a schema/guile/lisp programmer, but I do program in other languages. I would appreciate any hints to get me back on track with gnetlist. Thanks in advance.

It's a list of attributes for which you want extracts. http://geda.seul.org/wiki/geda:bom_readme DJ, Thanks! That got it going. I thought it was something like that, but wasn't sure. Onward and upward!

Re: gEDA-user: gschem unresponsive to keyboard input
Kai-Martin Knaak wrote: -BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Hi. One of the electronics newbies I teach geda, hit a strange input mode in gschem today. The GUI did not respond to the usual key-accels (ee, m, i...). Instead, on the bottom right of the window the status line displayed the letters just typed in upper case. [return] , [escape] or any combinations we came up with did not end the mode. In the end, we restarted the session to bring back the expected behavior. What is this mode supposed to do? How would it be entered? How can it be ended? Can I assume you tried Caps Lock? I am always forgetting to remove Caps Lock and gschem exhibits the behavior you describe. The commands are case sensitive. HTH.

Re: gEDA-user: Refreshing symbol libraries ?
Amond, I had this problem too, until I found the refresh icon: Add - component In the Select Component... window, click on the circular arrows icon to the right of the Filter box. That should refresh the listing without restarting gschem. Still using gschem 1.4.0.20080127. I sure hope they didn't drop that feature in the later versions...

Currently, when I copy or create a new symbol into the project directory, I have to restart gschem to make it visible in the component browser.

Re: gEDA-user: Open Source mechanical CAD on the horizon

Although it is still lacking important features, much of the basic infrastructure is already up and running. http://en.wikipedia.org/wiki/FreeCAD_(Juergen_Riegel) ---(kaimartin) Kai, Have you, or anyone in the group, used FreeCAD for any useful work? I just downloaded the source code for Linux and took a look at the docs. Although they may not be up to date (file date of Jan 7, 2010), they have no substance. It is proclaiming there isn't yet much in the way of GUI commands to implement the internal drawing functions. I am looking for a free and Open Source mechanical drawing program to complement gEDA. i.e.: Okay, we have the PWB out for fab, now let's design and document an enclosure! I have been using gschem's drawing capability for much of my projects' mechanical documentation. For the most part, it is acceptable for that, however, gschem has a few limitations, such as lack of drawing ellipses for oval speaker cutouts, that real mechanical drawing programs support. FreeCAD looks promising on the surface; however, before I install and/or update a lot of Linux system support libraries for FreeCAD, I would like to hear from someone who actually found FreeCAD useful at this stage of its development (version 0.9.2646).

X is supposed to be reserved for sockets. For example, XY2 is a socket for Y2 and XQ1 is a socket for Q1. So, the Wikipedia is correct.

Re: gEDA-user: arcs and circles in PCB via gui
DJ Delorie wrote: I was thinking of an edit-arc option that lets you grab the endpoints and drag them to new angles. If you grab the center, it moves the arc. If you grab an enclosing-rectangle-corner, it resizes the arc. http://www.delorie.com/pcb/tmp/arcedit.png ___ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user DJ, et al, Have you looked at gschem's arc GUI code? That is the way its arcs can be edited. Selecting the arc displays tags on the arc endpoints. Dragging one end (I am not sure which end) rotates the arc around the axis. Dragging the other end changes the length of the arc. Although I have not used PCB yet, I can see advantages to having the PCB and gschem GUIs be consistent.

Re: gEDA-user: the joy and sadness of new boards
DJ Delorie wrote: Just got a box of panels from Advanced Circuits. Five panels, ten boards per panel (two each powermeter, usb-gpio pod, and three pod modules - ten sets of boards total). Joy! Unfortunately, I have no way of separating them into individual boards yet. Sadness! But I do have a 60 degree v-scoring bit for my router table. Joy! Last time I used it, the pcbs were too flexible for the big hole the table had around the bit. Sadness! I was thinking of taking an old 7 table saw blade and re-grinding it to a 60 degree point. I can make a zero-clearance insert for it, to ensure correct cuts. Joy! However, I don't have any of the parts for the boards yet. Sadness! But now I get to go through the BOMs, figure out the best parts to use, put together a digikey order, come up with some hobby money, and wait for it all to arrive. Joy! No, wait... sadness? Crap. ___ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user DJ, You don't say, but I assume you have .062 or thinner G10 panels. Do you know anyone with a sheet metal shear? I used that in the past, although the glass fiber is a bit hard on the shear. On the other hand, there is a lot less fiberglass/copper/plastic dust than a saw or router bit. Harbor Freight has a small 30 shear that should be big enough for 15 panels. It is a few hundred dollars to buy it, however. http://www.harborfreight.com/cpi/ctaf/displayitem.taf?Itemnumber=5907 If you are intent on sawing, how about a Dremel cutoff disk? That should be low-cost. Wear a dust mask, though. Girvin ___ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
