The Finished Product

Dark Roast, originally uploaded by Robbi Baba.

Here they are, after another 25 minutes of roasting at 350 degrees. They are definitely bitter tasting, but not in a bad way--if that makes sense. I ate at least 15 today and didn't think they were all that strong a stimulant. I never felt a distinct buzz.
All in all, it was a very satisfying project. I'd do it again.
