I am looking at the PCB file in Eagle for RPM's Usb to Dmx Dongle board and the Dmx DcSSr boards. But in general.

Where blue and red lines cross of run together does that usually mean its a 2 layer board?

How do I etch that - or is that a "send out" board?

Any suggestions where to get a few boards made?

How do I get Gerber files out of Eagle?

Thanks

The Red lines are the top layer, the Blue lines are the bottom layer. FYI, the DMX8 DCSSR board uses copper filled areas that won't show up when you first load it until you use the "ratsnest" command.

To get boards made from Eagle files, you will need to find a board house that supports the Eagle file format (not many do), or convert them in Eagle to Gerber format.
I convert my files to Gerber format before sending them out to get PCB's made.

I usually use Sure Electronics for small runs (25 or less) of boards and the quality of their boards is very good. They usually run auctions on Ebay for their service, such as this one here http://cgi.ebay.com/Low-Cost-2-Layer-PCB-Manufacture-Service-1-5-boards_W0QQitemZ230337719273

There are a few tutorials out there for creating Gerbers from an Eagle drawing.
Here's one from Sparkfun http://www.sparkfun.com/commerce/tutorial_info.php?tutorials_id=109 and here's another one I found http://hobby_elec.piclist.com/e_eagle44.htm

Can someone let me know if these are the gerber files I need to get a board done outside?

I think I am missing the drill text file - who do I produce that?

Thanks

Almost. You will need the drill files as well.

Look at this tutorial http://hobby_elec.piclist.com/e_eagle44.htm and read the "Creation of a Drill Rack file" and "Creation of Excellon Drill Files" sections.

This is how I create my files, with the exception that I use MM instead of INCHES for my drill rack file.

Once you do all this and have created your Gerber files, I highly recommend you use ViewMate to check them before sending them to a board house. This program will let you load and view the Gerber files.
The free edition of ViewMate can be downloaded here http://www.pentalogix.com/Products/ViewMate/register.cfm

All done - off to Sure Electronics.

If they are for Sure-Electronics, they are very picky and won't accept them in that format.

I'll attach the CAM files I use to process gerbers for them, they are modified specifically for their format.
Unzip them and put them in the Eagle CAM folder and use these instead of the original CAM files when you process Gerbers for for Sure-Electronics.
