If you infringe a patent "willfully" (i.e., you know about it, and have reason to believe it applies to you) you can be subject to triple damages. But you aren't safe just because you didn't know about the patent. And doing something "non-commercially" means little. We all know that estimates of commercial harm can be manipulated-- looking at the damages that are routinely awarded in copyright infringement cases should be enough to convince you of that.
