Cadsoft Eagle libraries

Hi Guys
·
I’ve just started playing with Cadsoft’s Eagle PCB software. Guenther you’re right! The good German design is plain to see. (Have you ever been given a Mercedes Benz for free? No! Well just download the Eagle Lite software to see how it feels).
·
But I’m very lazy. Does anyone have the SX and Stamp libraries? Particularly the SX SMD components.
·
This topic must have come up before but I can’t find the string.
·
Kind regards from Kwa Dukuza

As always - You are a star.
That solves the SX products, now Im just looking for BS2-40.

I'm pretty sure, there is no BS library available for EAGLE. Mayby, you take the challenge, and design one. But be warned, creating LIBs for EAGLE is a bit "tricky" - I did one for my personal use but still have not figured out all the bells and whistles of library design. I'd really like to see a better documentation.

Thanks for the challenge but I'm trying to spend less time of my spare time·on the PC and more time working with electronics.·I already spend 5+ hours a day on a PC at work.
Kind regards from a PC somewhere in Kwa Zulu Natal (South Africa)

This is not a sig. This is a duck. Quack.
thanks for the
I downloaded the Eagle Light software and it is very nice! I love the auto router feature! I tried PCB123 and I dont see where you can use auto routing. My question is, Can you send in your designs made from Eagle Light and have a board(s) made from it?

Can you provide a picture of one of the boards you had made? I would like to see how it looks.
<edit> The last OS my scanner had a release for was Win95, Ill see if it will install in XP when I get home </edit>

PS Ive thought about creating an "Creating Eagle Libraries for Dummies", but Ive found the helpfile to contain all the nessesary info for normal operation of the program. You have downloaded the help file too correct? I think they have a tutorial file as well.

I didn't mean to put you through so much trouble. I just wanted to marvel at a board you created on your own using Eagle Cad. Don't worry about posting a pic of your board. Since you do not have a quick and easy way to post the image I wouldn’t·bother with it. I appreciate you trying though!
As for the help files, I thought that·is what came with the installation? I found a book that explains how to use Eagle Cad in detail; I am going to get this book. I Hate sitting at the computer trying to read information for extended periods of time. I'd rather get a book I can hold in my hands, lay down on the couch and do my best focusing and thinking while reading the information.

The files Im refering to are:

there actually is a copy-paste functionality in EAGLE but it is a bit "hidden". First, mark the part(s) you want to copy as a group, next select the "cut" function (the scissors), right-click on the marked group, go to the location for pasting (may also be another schematic), finally, click the "magic wand", and you can paste the parts. Don't worry, the "cut" does not really cut, it makes a copy, so the original group will remain in place.
I have EAGLE professional here, and I successfully use it for my business projects.
BTW: I've never been in SA so far. I hope, one day I have the chance to go there.

5 boards, 5 days turn, silk screen and soldermask included for $75.
I use Advanced circuits for the higher quality stuff. But these guys are
really good for quick turn cheap stuff. (It helps if you set min clearances
to around 15 or 20 mils. I have had some shorts on really tight spaced
boards).

Which fab house did you use for this one? Was it Advanced Circuits?

I used the smash operator to place the text of parts in convenient locations wherever possible, an unfortunate side effect of the smash operator is that it places 1 mil location crosses in the silkscreen layer (they are the "handle" to move the text within Eagle). After submission of the board, I got an email from them asking what I wanted to do with the crosses, since they were below spec. I told them I didnt want them and they erased them from the Gerber file before production.
Now that some time has passed, I can see places where the routing wasn't optimal. I don't use the autoroute feature because it begins to throw a fit when you start tightly packing components together, and I frequently disagreed with it's choice of routes. For instance for the SRAM, the control lines, the data lines, and the lower address lines have priority of routing since the signals transistion @ 50MHz (/WE transitions even more quickly through a delayline-XOR circuit) yet the autoroute persistantly tried to route the higher address lines first.

I have been messing around with it for about three days and have figured out how to use busses, name parts, move groups, copy paste, how to connect ground and many other various things such as changing the grid size, turning on various layers etc. I have done all this without reading any help files. I have been able to figure out most of the functions just by playing with the software. I'm at the point where I could easily design a board except for creating gerber data.
There is one problem I am having:
I can't seem to find common parts such as through-hole resistors, NPN & PNP transistors, etc. I have been able to download and use the capsmaster.lbr for most of the common caps but I have also downloaded about a dozen other libraries and none of them have what I need.

The power traces are too small, they should be wider.
Tie the back floodplane to ground, right now it's not connected to anything.
The switch SW1 has no purpose, both ends are already connected at the left pin of the power connector.
There should be bypass caps on both the input and output of the regulator.
This isnt that important for stamp designs, but for SX designs I avoid using right angles in signal lines, it can cause reflections of the signal.
Otherwise, it looks like a good design.

Pretty darn good for a first design!· I'm embarrassed to say how long it took for my first.
The aspect ratio of the BS2 looks correct but you might want to check dimensions.· The first BS2 library component I downloaded from the cadsoft ftp site had a width of 0.7 instead of 0.6.·
Later on, if you design with surface mount components, you may want to increase the pad size for·some of the library components.· They are okay for reflow soldering but a little tight for hand soldering.
Creating gerber files is pretty straight forward.· It's just a matter of having the correct layers turned on.· Download a free gerber viewer like Viewmate to check your work.· Ask your chosen board manufacturer what they require.··I used SierraProtoExpress.··For·my two layer board, I needed 5 gerber files (3 top, 2 bottom) and·two Excellon drill files.
