I've downloaded the above board and notice that Eagle shows there are 17 airwires. I'm not sure if I need to correct these (not that I know how at the moment!) or whether I can go ahead and make the board anyway.
Anyone with any advice for me?
UPDATE: 28th Nov
Following the post by jloyd (below) I have downloaded the file from this site, I'm not sure where I got the version with the airwires (perhaps from a link within the Arduino Robotics ebook?) but the version of the board file form this site doesn't have the airwire problem
John, first off thanks for writing the AR book, it's been a great intro. I've also been looking at your osmc board and have a related question. I'm building Lawnbot variant using a much lighter platform so I think your smaller board will work well. Is there a matching BOM? (the schmatic doesn't seem to have any values, just names) The current OSMC board seems to list a lot more components (other than the quantity of FETs) so I'm uncertain of matching that to your version. Thanks in advance for any help!...
Just an update to my own post!...
I was able to match the current OSMC parts list to John's scaled down version and added the component info to the schematic.
Softy, I didn't have any airwires in the version I downloaded here but I did fattened up the traces a bit to make it easier (for a newbie like me) to etch the board. (Otherwise it's the same) If you're interested in the updated files just shoot me an email (firstname.lastname@example.org)
