gEDA-user: Bug in PCB's Gerber generation?
Hi Andrew, I just pulled PCB from git head and I have trouble with arcs in Gerber output. I strongly suspect the latest commit: layers which do not have arcs appear fine in gerbv, but automatic zooming layers which contain arcs zoom out and give coordinates in the range of several meters (with the screen staying lack). Also my outline has a single arc in one corner and this is precisely this segment which is missing. I can not prepare a test case right now but will tomorrow (it's almost 9 pm here), if you've not beat me to fix it before.

Re: gEDA-user: OT: help needed; asymmetric load after rectifier seems to disrupt its working.
When you put two capacitors in series, there's no way to know what the voltage between them will be. You have three with a common central connection Vx. V1 acts to charge the node, the loads act to discharge it, so an unequal load means unequal discharging and thus nonzero average node voltage. Since D1 and D2 may have different average currents through them, Vx will adjust until the average current through R2 is the same as the net current throuth the two diodes. Can you split the filter into two filters, one for each load? or at least move C1 to the Vx side of the filter, and split it into two capacitors? ___ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user

Re: gEDA-user: OT: help needed; asymmetric load after rectifier seems to disrupt its working.
Thanks DJ, I had the same thought that Vx was floating somewhere unwanted, that's why I added the resistor (which didn't work). Gazing at this problem for a couple of days make me miss the obvious, just split the filter. Brilliant. I'll give it a try. Robert.

Re: gEDA-user: gschem saving symbols
The plan is to add a 'Save symbol instance as...' to the right-click menu. It will open the file chooser in the directory of the original symbol and load file name from device attribute. Saving a schematic uses f_save in libgeda, I am adding a f_save_symbol. First I loop selected objects stopping at the first complex obj. Then get the text of the symbol with o_save_objects(toplevel, s_object-complex-prim_objs, 0); This returns almost the text needed to create the symbol file. The position of all the objects in the symbol are big numbers for the position they had in the schematic. Is there a reason to make these numbers small near the origin like in the original symbol file? -Josh Jordan --- On Fri, 6/17/11, Steven Michalske smichal...@gmail.com wrote: From: Steven Michalske smichal...@gmail.com Subject: Re: gEDA-user: gschem saving symbols To: gEDA user mailing list geda-user@moria.seul.org Date: Friday, June 17, 2011, 12:48 AM On Jun 16, 2011, at 9:37 PM, Colin D Bennett [1]co...@gibibit.com wrote: On Thu, 16 Jun 2011 20:55:57 -0700 (PDT) Josh Jordan [2]outerspacema...@yahoo.com wrote: I could implement a save-symbol-as capability.
