Re: gEDA-user: anyway to make rectangular holes such as these?

2011-01-30 Thread Stephen Ecob
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.

The difference is that whether you use a laptop with an external
screen and keyboard or not the UI behavior is pretty much the same. 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.

Firstly, the general shape is not so much the problem, but dimensions of
the shape.

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.

We already do support bridges with rounded corners. 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: Thermals on Pads

2011-01-30 Thread asomers
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.  I need a
little help though: the pcb code base is too large for me to grok all
at once.  Could someone please tell me where to start?  What would I
have to modify to allow this?

As I said in my original post "the screen is a bit tiny", for me that
implied that no one is going to do serious work on a phone size device,
but that's going to be different for tablets. On the phone it's nice to
show some schematics / layouts to friends (if you don't have your laptop
with you :-) ) and using a stylus to draw lines in pcb works well. So
lets wait for affordable tablets with sufficient size, at least the
processor architecture is no concern.

There were rumors in a german newsticker that Intel is going to announce
a tablet with MeeGo in June with availability 3Q.

It seems someone invoked irony using the following comment in the code:


  /* this search is guaranteed to succeed */
  SearchObjectByLocation (LINE_TYPE | RATLINE_TYPE, &ptr1,
  &ptrtmp, &ptr3,
  Crosshair.AttachedLine.Point1.X,
  Crosshair.AttachedLine.Point1.Y, 0);

BANG. (Remember kids.. never be smug about what will / won't succeed!)

Actually, its not the search's fault.. the Crosshair.AttachedLine stuff
is probably not getting set properly.


SO - what is the "CORRECT" behaviour for "Only names" mode.. allow line
creation, or deny it completely? This will probably alter where / how we
fix this.

I can confirm for pcb recently compiled from git.  

This is the specific sequence I did to achieve segfault:

1) Settings -> Only_Names

2) choose the line tool

3) left mouse click on canvas

4) left mouse click on canvas

5) [u] to undo

--> immediate segfault. No other errors reported


If I ended the track with [esc] no segfault would occur.
I noticed, that the same procedure with pcb from squeeze
does not segfault. But it still behaves a bit strange on 
undo: The next segment seems to start somewhere off canvas.

(As I said ;)).

Still - most places I went to do a repair, I'd want to take a laptop or
at least a tablet. Getting out that remote without a computer seems like
as well thought out as going to do said repair and forgetting to pack
your soldering iron.

That matches the same set of steps where I can trigger the valgrind
warning.

As an added data-point, I was able to reproduce with "Only names"
switched off when I started line-drawing, but switched it on mid-way,
before I hit undo.

A cursory glance didn't suggest what might be wrong yet.. please file a

Actual design work probably not all that useful do to small size.
The place where it wold great is in being a trouble shooting tool in the field.

You're in the field and need to see the layout to find where that
trace once was after it vaporized from a component failure,
 so you can put a jumper in its place...

You're in the field and need to replace a capacitor, you need to see
the value on the schematic...

All the while you are someplace like here, where the window of
opportunity is small to non-existent:

I too was waiting for Meego, last week Nokia said they where going to
Android, no one is sure what is going to happen to Meego. :-(

Ok, I tried again, empty board, and yes, the segfault does not happen
when a line draw is completed (with the middle mouse button).

It only happens when I hit u (undo) after drawing a track segment, but
did not terminate the draw (with middle mouse button).

Ignore the line-numbers, I'm running my PCB+GL branch. I didn't get a
segfault, but that might just be down to luck.

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 ;)

gEDA-user: gnetlist (bug?) subcircuit symbol without pinnumbers

2011-01-30 Thread Stephan Boettcher

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.

   Android is layered atop Linux.

   The iPad OS (also the iPhone OS, called iOS) is multitasking as of

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".


Only my opinion.

Best regards.
