Re: gEDA-user: anyway to make rectangular holes such as these?
A quick solution is to just use large round holes - large enough to accept the rectangular pins. A bit ugly, but I've successfully done that in the past. If you're going to wave solder it would be wise to talk with your assembler about whether their wave machine will handle it well. Another approach I've seen is to place a row of overlapping holes very close together. You can do this by hacking the .PCB file in a text editor. Many PCB fabricators can handle this approach, some cannot - check with your board manufacturer first. ___ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user

It might be more convenient to use with a desktop style set up, yes, but it is still pretty usable on a plain laptop. There is no chance to get a similar level of experience on mobile devices (good luck with wiring up your schematics with a capacitive touch screen). It might be useful to have a limited functionality mobile viewer or (simple) editor, though. In this case, however, I'd skip on writing native applications entirely and go straight to the web. What's needed is a bunch of PHP/Ruby/... scripts accessing libgeda backend (once it is complete enough) and perhaps some client-side Javascript for better experience. That IMHO would be the quickest way of building applications that are truly portable and adjust to the user's platform limitation. It could also be useful on desktop for group work - for example as a browser (or editor if some versioning system is used) of user contributed symbols.

Second - PCB calculates what it thinks the thermal finger width should be, but actually calculates the geometry wrong - so the thermal you see is not what the calculation PCB does suggests it should be This is evident at certain clearance sizes, where the thermal cutouts start to overlap and cause polygon problems. At some geometries, the general shape is wrong - we need to restrict some of the dimensioning to keep the thermal shape valid, or add routines for a different thermal shape in these cases. > -- Peter Clifton Electrical Engineering Division, Engineering Department, University of Cambridge, 9, JJ Thomson Avenue, Cambridge CB3 0FA Tel: +44 (0)7729 980173 - (No signal in the lab!)

And what we do not support is anything suitable for TSOP package pads(long thin pads near to each other). But the big problem with you current implementations is the size of the bridges. The size is somewhat magicaly calculated from the size of pin and from the size of clerance. But this is neighter working nor probably right. With big clerance the shape becomes completly bogus(at least for the rounded versions).

I think it would be acceptable to change geometry on the community if it happens at the same time as a new version of the PCB file format. That way PCB files in old file formats could have the old geometry (legacy mode), and newly created ones could have new geometry. ___ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user

gEDA-user: Thermals on Pads
When I design surface mount boards I make extensive use of planes, and it is a severe annoyance that I can't automatically connect those planes to component pads. The standard solutions to this problem seem to be either: 1) Use a solid plane. But that makes soldering difficult. 2) Draw a very small solid rectangle to connect your pad to the plane. That works, but it's labor intensive. I'm a novice to the pcb code base, and I couldn't find much developer documentation, but I am willing to try to add this feature.

Perhaps I'm being short-sighted, but I don't see a great potential for serious EDA work on phone sized devices. Even if they get the screen-resolution high enough, the size is very small for design work, and the input problematic. For phones, I just about see the case for a schematic / PCB viewer where one could lookup or query a design whilst doing a field repair. For tablets - that is a much more interesting proposition.. given a big enough size, the possibility of a novel experience is high. User input is again a challenge though.. finger touch will likely not provide the fine-grained control our software currently needs to operate productively. A stylus input might be higher resolution.. If I had the spare cash (or someone was to send me one in the post ;), I would LOVE to work on getting PCB editing on A Wacom Cintiq: http://www.wacom.com/cintiq/cintiq-21ux.php Even then.. We don't know until we've tried it - whether it would liberate the PCB / schematic designer in the same way it would an artist. PCBs and schematics typically constrain to fairly ordered geometries, and perhaps the computer mouse is an input device better suited to that? That said - I'm fairly sure working with PCBs on a Cintiq would be awesome... send me one and we'll see ;) -- Peter Clifton Electrical Engineering Division, Engineering Department, University of Cambridge, 9, JJ Thomson Avenue, Cambridge CB3 0FA Tel: +44 (0)7729 980173 - (No signal in the lab!)

gEDA-user: gnetlist (bug?) subcircuit symbol without pinnumbers
Hi, a few comments/questions on this weekends gnetlist experince: gnetlist via gsch2pcb complains a lot, and adds a pin U?-? on every net that connects to a specific symbol for a subcircuit (with source= attibute). The error messages are not helpful. It took a while to figure out that gnetlist is unhappy about not finding pinnumber= attibutes on the pins of that symbol. Why does a subcircuit need pin numbers? The connectivity is establisched via pinlabel= (although pinnumber= would be more intuitive, at least until we get rid of all the attribute overloading, and since pinnumber= seems to be required for unknown reasons). Why does gnetlist not tell which entity it is complaining about in its error messages? $ gnetlist --version gnetlist: unrecognized option '--version' ... oh, that is unhelpful as well, no cut'n paste from the gschem about box either. Let's see, $ dpkg -s geda | grep ^Version Version: 1:1.6.1-4 Debian sid. -- Stephan ___ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user

Android is layered atop Linux. The iPad OS (also the iPhone OS, called iOS) is multitasking as of release 4.0. Incidentally, it too is a UNIX-based platform...only its user interface (pre-4.0 anyway) prevented user-visible multitasking. -Dave I don't know about Android, but I have a Nokia N900 running Maemo and there you can install a debian and get binaries for the armel architecture via the package manager. So at least the processor architecture is supported. I have gschem (1.6.1.20100214) and pcb (20091103) installed, the screen is a bit tiny, but thinking of Tablets runnig Meego that seems to a a viable option. I think this too (I have a N900 too). Maemo (I'll wait the same from Meego) is a "good" environment with multitask, and easy change between task, and (I think) "easy" to port apps (Debian install option in Maemo is great). Instead, I don't like Android (I have a Entourage Edge with Android 1.6): no "real multitasking", no "easy change between task", "google register needed" (or apktor, aptoide option, this is I use, with too much less apps), and no easy porting of apps (go, for example, to VLC and read about). But, I'm afraid that Android will be a sucess (thanks to Nokia and his ugly comercial vision). About Ios I don't know, only use ocasionally on IPod and Iphone of some friends. I was asked this too some time ago, because, I view that tablets and other devices (like e-readers with double screen) with Android/Maemo/Meego are going to users, and is a opportunity for the free world to "hit first".
