gEDA-user: cheapest pcb manufacturer that does silkscreen/soldermask
Hi all, I have been using 4pcb for awhile now and even for a small board the cheapest option they have is $250 for an order of 5 boards (their minimum quantity). They have a bare bones (no silk/mask) option that I have been using that allows you to order 2 for $60 which is a great option most of the time. I have order their silk/mask board for $250 a few times and their quality is superb however I'm looking for something cheaper and perhaps has a lower minimum (maybe 2). I'm willing to deal with a lead time of up to 2 weeks. Any suggestions? ___ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user

gEDA-user: Fluky Fluky layout printing problem!
Here's a weird problem. I am using two inductors with the same footprint in a small two layer design. After laying out the board I exported a ps version of the board. I then used ps2pdf to convert the layout for my printer. When I open the pdf document in windows the layout looks exactly the way it should (all the foootprints are correct). When I print out the etch patterns to make the board both pads for both inductor are missing even though they are there in the pdf! Has anyone ever had this happen? Here is the foot print: Element [10 10 -25000 -2 0 100 ] ( Pad [-20650 0 -20642 0 11000 1200 1500 1 square] Pad [20642 0 20650 0 11000 1200 1500 2 square] ElementArc [0 0 25000 19650 250 40 100] ElementArc [0 0 25000 19650 70 40 100] ElementArc [0 0 1 1 0 360 100] #cirle ElementLine [-15000 -4900 -15000 4900 100] #inside verticle lines of pads ElementLine [15000 -4900 15000 4900 100] ElementLine [-24400 -4900 -15000 -4900 100] #bottom horizontal line of pad ElementLine [-24400 4900 -15000 4900 100] ElementLine [24400 -4900 15000 -4900 100] #top horizontal line of pad ElementLine [24400 4900 15000 4900 100] ElementLine [-24400 -9800 -24400 9800 100] #outside verticle lines of pads ElementLine [24400 -9800 24400 9800 100] ElementLine [-8500 -18000 -24400 -9800 100] ElementLine [8500 -18000 24400 -9800 100] ElementLine [-8500 18000 -24400 9800 100] ElementLine [8500 18000 24400 9800 100] ) ___ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user

Re: gEDA-user: git based wiki
If we're talking about changing things, here's my totally unreasonable and unrealistic documentation system wishlist. - Markup: should look as much like a plain text document as possible, so that it's easy to read and edit the documentation without having to continually process it to double-check that it's going to come out right. Nice-looking tables are essential. Bonus points for syntax highlighting mode for Emacs. An example of IMHO *lovely* markup is reStructured Text. - Conversion: should be able to convert the *same* sources to man pages and DocBook XML, and onward to XHTML / HTMLHelp / PDF etc. This is essential so that people who want to contribute to any gEDA documentation only need to learn one markup syntax. An example of IMHO excellent conversion support is ASCIIDoc. The git docs use it especially effectively. - Version control: reference docs should be maintained in-tree so that each branch (e.g. stable and unstable) has its documentation alongside it. Not so fussed about things like getting started guides. It's really good for developers to be in the habit of updating docs in the same patch as changing behaviour. Lots of systems can support this. Would need a docs coordinator or something to assist people who want to help with documentation work but don't have git expertise.

They have a bare bones (no silk/mask) option that I have been using that allows you to order 2 for $60 which is a great option most of the time. I have order their silk/mask board for $250 a few times and their quality is superb however I'm looking for something cheaper and perhaps has a lower minimum (maybe 2). I'm willing to deal with a lead time of up to 2 weeks. For low quantity or prototype boards, and especially smaller boards, I don't think you can possibly beat DorkbotPDX (http://pcb.laen.org). For $5.00/sq in you get three copies of your board--ANY SIZE, no minimum, no setup fee, and U.S. shipping included. That's only $1.67/sq in total, and you get solder mask and silk screen both sides, minimum 6 mil/6 mil trace/space and 13 mil drill size.

Gold RoHS, 8 mil trace/space, 24 mil minimum drill, 8 mil minimum annulus. They'll let you put as many designs as will fit on either size panel, and they will cut the panel apart for you for free as long as they can do so using only straight cuts all the way across. They will only cut designs to even rectangles. Additional features like silk on bottom, large numbers of holes, drills not in their standard rack, etc. are available at low cost. Turnaround time is usually about 3-4 weeks. Only caveat with them from my experience is they require you to fax your initial order, to keep your CC info from going over the 'net. -- There are some things in life worth obsessing over.

Floating tracks might trigger a DRC, but I think they are perfectly valid and I'd rewrite the DRC. I can't remember if DRC2 or anything else complains about floating tracks... John @John, it's interesting that you give an example for collaboration that's in chip design. Chip design is closer to my (professional) home turf than board design (just a hobbyist :-) ), but I always saw the limitation about what I can do in my basement (and limited myself somehow). The chip design floe I know reserves the lower level metal layers to sub-cells and the higher level metal layers to global wiring in reserved to connect the sub-cells (with some simplification). @all on a board level collaboration I see basically two different approaches: 1. time slicing 2. area slicing 1. time slicing One person owns the board for a given period of time, the workflow is: checkout -- work on the board -- chaeckin and the next person takes over. This is the approach to use if the contributors are in different time zones and it really requires godd communication. I think this is supported by geda out of the box as it boils down to a communication problem. 2. area slicing This is far more challenging than the work flow described above The design needs to be partioned into sub-cells, process them independently, and do the connections between thte sub-cells on reserved layers. There are some requirements that the gaf design flow can't fulfill (yet). Net: the question is how you define collaboration that defines your infrastructure sequential or concurrent updates to the desing library. - From my experience the time slicing approach is easier to handl and better supported by tools (cvs, svn...) - -- Mit freundlichen Gruessen Dietmar Schmunkamp -BEGIN PGP SIGNATURE- Version: GnuPG v2.0.15 (GNU/Linux) Comment: Using GnuPG with SUSE - http://enigmail.mozdev.org/ iEYEARECAAYFAk06OCoACgkQn22l+QvEah2qNACdF+rzHCg2/yeEgfwMs1jeEV4w wsoAnA8+SB1rilTObZvzmI13y7gFqGVV =giNs -END PGP SIGNATURE- ___ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
gEDA-user: PCB House Philway Products burns to ground
Heads up if anyone here uses the board house Philway: At approximately 10:30PM on Wednesday night, Jan/19/2011 http://www.philway.com Philway Products Inc. of Ashland, Ohio burned to the ground http://www.fox8.com/news/wjw-pictures-ashland-plant-fire-012011,0,904988.photogallery Fortunately no one was hurt. Philway was the oldest continually operating board house in the US. It was also my preferred PCB vendor, sharp people and good quality for the rugged environments I deal with. Purportedly the owner said on a TV interview that he was not sure if he was going to rebuild or not. Will be a great loss if that is the case. Also makes me wonder even if they did want to rebuild, would the http://www.epa.gov EPA allow it? Ammonia, Sulfuric Acid, Nitric Acid, Formaldehyde and other chemicals are used to make PCBs. Philway was big in the military and Hi.Rel. Aerospace, there could be a significant ripple effect from this event. I've never been a fan of Just In Time inventory for just this reason. Luckily from my perspective no work of mine was in process. Someone wondered what will happen about tooling? Do we have to pay for it again should they rebuild? Obviously we will if they don't rebuild. Time will tell, the lives of those involved deserve more consideration and help right now, some links from the news: http://www.wmfd.com/newsboard/single.asp?Story=44669 Firefighters Battle Philway Products Fire In Ashland http://times-gazette.com/news/article/4966992 1/19/11 Philway Products Fire http://www.times-gazette.com/news/article/4967083 1/20/11 Philway Products Fire - morning http://www.times-gazette.com/news/article/4967340 Officials probe cause of factory fire: Firefighters keep blaze from stored chemicals http://www.mansfieldnewsjournal.com/article/20110121/NEWS01/101210315/40-Philway-workers-in-limbo-after-big-blaze Philway Products workers in limbo after fire destroys factory http://www.mansfieldnewsjournal.com/article/20110120/NEWS01/101200332/Ashland-factory-Philway-Products-destroyed-in-Wednesday-fire Ashland factory, Philway Products, destroyed in Wednesday fire http://www.mansfieldnewsjournal.com/article/20110120/UPDATES01/110120008/Ashland-factory-fire-No-evidence-of-criminal-intent Ashland factory fire: No evidence of criminal intent http://www.fox8.com/news/wjw-pictures-ashland-plant-fire-012011,0,904988.photogallery PICTURES: Ashland Plant Fire -- http://blog.softwaresafety.net/ http://www.designer-iii.com/ http://www.wearablesmartsensors.com/ ___ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
gEDA-user: speed of the gschem GUI
Hi. While working on a fairly large schematic I noticed that panning in gschem is way less snappy than the same circuit rendered as PDF in evince or kpdf. There is no benchmarking available. The ratio seems like 10. While my schematic pans in gschem with 3 to 5 FPS, it is definitely beyond 30 FPS in the PDF renderers. Since both applications deal with lines and characters, I'd naively expect similar performance. Or did I miss something? Is there any hope to speed up the gschem GUI? ---)kaimartin(--- -- Kai-Martin Knaak Email: k...@familieknaak.de Öffentlicher PGP-Schlüssel: http://pool.sks-keyservers.net:11371/pks/lookup?search=0x6C0B9F53 ___ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
