Step 2: Print the board
Unless you got the board as part of a kit (not yet available, but maybe someday) you will need to have it printed.
For a long and wordy description of how to get a board printed (along with links to even more articles on the subject) see step two of my other article "Build an electronic score keeper".
The board file in eagle format is included in the attached "eDie-1.2.zip" file.
If you don't want to bother with the hassle of formatting the board for printing, you can order it right from BatchPCB for $5. Unfortunately there is a $10 setup fee per order and a shipping charge, so unless you are ordering other boards at the same time, this is a bit pricy.
I have three copies on order from dorkbotpdx in purple for $8.05, I'm excited to see how it turns out.
This board is small enough to qualify for the 10 (5 of tested for printing errors) for $10 deal from seedstudio.com. I am also waiting for those to arrive from china for evaluation.
Do you have to print the board? No, the board is technically optional, you could wire all this by hand. But it's not easy or pretty. See the pictures in the notes step for the original hand wired prototype.
