I would be surprised to see it in a TO92 package. The voltage drop does not care for low current applications, only the power does.

gEDA-user: Question regarding 1st LTSpice simulation
I tell my son the only dumb question is the one never asked. So with that... I'm doing an LTSpice simulation and following Stuart's howto. In the Running LTSpice with gEDA designs step 5 is: Create a link from your netlist output.net and a netlist in the directory in which SwCADIII lives. Make the netlist suffix .cir. For example: ln -s ${DESIGN_HOME}/output.net ${WINE_HOME}/.wine/fake_windows/Program Files/LTC/SwCADIII/MyDesign.cir My questions are these: 1. Earlier in the howto I was directed to netlist my design and name it design.cir. This is the netlist in my design directory and it ends in .cir not .net. Should Stuart's howto read ${DESIGN_HOME}/output.cir and not output.net? 2. Did I miss something and I was supposed to copy the netlist to the directory in which SwCADIII lives or does the link create a phantom netlist?

On Cygwin/X, reopening a gschem dialog restores its original position, but with a small vertical offset. The workaround is to show the dialog before restoring its position. The docs for gtk_window_move() offer a possible justification: Most window managers ignore requests for initial window positions (instead using a user-defined placement algorithm) and honor requests after the window has already been shown. The downside is, if you have a slow system, you could see the dialog appear briefly at the old position, I suppose. --- gschem/src/gschem_dialog.c |6 +++--- 1 files changed, 3 insertions(+), 3 deletions(-) diff --git a/gschem/src/gschem_dialog.c b/gschem/src/gschem_dialog.c index b4eefd0..bc5771b 100644 --- a/gschem/src/gschem_dialog.c +++ b/gschem/src/gschem_dialog.c @@ -220,6 +220,9 @@ static void show_handler (GtkWidget *widget) gchar *group_name; GschemDialog *dialog = GSCHEM_DIALOG( widget ); + /* Let GTK show the window */ + GTK_WIDGET_CLASS (gschem_dialog_parent_class)-show (widget); + group_name = dialog-settings_name; if (group_name != NULL) { @@ -230,9 +233,6 @@ static void show_handler (GtkWidget *widget) dialog_geometry, group_name); } } - - /* Let GTK show the window */ - GTK_WIDGET_CLASS (gschem_dialog_parent_class)-show (widget); } -- 1.5.3 ___ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user

gEDA-user: Footprint for test points?
Seems a trivial thing, but what do you all use as a footprint for test points on the board? I'm just looking for something I can stick a meter probe onto easily, and maybe solder a wire onto if I need to modify the circuit in an unanticipated way. I am thinking that either a fairly fat pin (which will end up plated through) or just a circular SMT pad would be about right -- and how do I make a circular SMT pad? I guess a square pad would be fine except for aesthetics and expectations. If anybody has a ready-made footprint, I'd appreciate a pointer to it.

Re: gEDA-user: Footprint for test points?
Seems a trivial thing, but what do you all use as a footprint for test points on the board? I usually just add vias wherever I need one; mine aren't official in that they're not in the schematics. I'm just looking for something I can stick a meter probe onto easily, and maybe solder a wire onto if I need to modify the circuit in an unanticipated way. You want a one pin, 35 mil drill, header. That's just right for soldering in a 25mil square pin or a 22 gauge wire. and how do I make a circular SMT pad? Create a line. Drag one end to overlap the other, creating a zero-length line. Cut to the buffer and convert to an element. Poof! Circular pad. ___ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user

gEDA-user: Special ESC Free Dog gathering this coming Wed, 9.19.2007!
-- Free Dog Gathering Announcement This month there are two exciting opportunities for a Free Dog gathering in Boston. We've already had one fruitful get-together at the Bear Rock Cafe in Reading. Now, coincident with the Embedded Systems Conference in Boston's Back Bay, we'll hold a second meeting so we can meet gEDA users who are in town for the conference! This time, we'll meet at the Trident Bookstore and Cafe, 338 Newbury Street in Boston's Back Bay: http://www.tridentbookscafe.com/NASApp/store/IndexJsp We'll meet at 7:00pm either at the bar or in the restaurant area. As always, the meeting will be an open and informal working session. Bring your laptop *and* wireless card! Some items to discuss or work on include: * Stuart will finally merge and commit patches submitted against gerbv! * Spice-sdb and that annoying pinseq attribute * Anything up with Fritzing? * Looking to next year: Best practices for mentoring Google's Summer of Code. * What's up at the ESC? * Whatever you are interested in! Free Dog is an association of like-minded hackers and engineers interested in free and open EDA tools. We hold monthly (or sometimes more frequent) meetings around the Boston area featuring informal networking, speakers, and camaraderie. Our goals are to learn more about CAD, engineering and scientific software, share ideas about our current projects, and -- most importantly -- have fun with like-minded people. We welcome new members and participants of all ages. Students are particularly welcome! Date: Wednesday, Sept 19th, 2007. (*** Note special day ***) Time: 7:00pm, Eastern US Time. Location: (*** Note special location ***) IRC: #geda For more details, please contact me privately at sdb (* AT *) cloud9 (* DOT *) net. ___ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user

Except when you have your boards fabbed with soldermask, vias end up covered. They just default that way; you can turn it off. My latest board has all the vias exposed, I just selected the whole board and umasked all selected vias. Something like this... Select-All View-Show Mask :ChangeClearSize selectedvias =1 mil :MinMaskGap selectedvias =3 mil Minmaskgap won't change anything with a *zero* mask, but setting the vias to some small but non-zero number lets you grow them out to your fab's minimum (mine was 3 mil clearance). ___ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
