Students in physics courses often use whiteboards to brainstorm, solve problems, and present results to the rest of the class, particularly in courses involving collaborative small group work and whole class discussions. The whiteboards contain a valuable record of students' collaborative work. Once a whiteboard is erased, however, its contents are lost and no longer accessible to students, instructors, or researchers and curriculum developers. We solve this problem using wireless-enabled digital cameras to create an archive of students' work on the photo-sharing website Flickr.com. This provides a persistent record of class activities that our students use frequently and find valuable. In this paper, we describe how this works in class and how students use the photos.

We used a Casio EX-S5 camera and Eye-Fi wireless SD memory card. Total hardware cost was approximately $150 at the time of writing.
