HASTAC’s spring newsletter reports on the ETCL-sponsored Humanities Physical Computing Research Group.  Engaged in practice-based inquiry, the group is using Arduino microcontrollers and programming to answer the following research questions: How does building circuits inform more screen-oriented modes of research and composition? How does programming shape our perceptions of writing and argumentation? What kinds of small-scale collaborations and learning climates are demanded by maker workshops? And what are the cultural and materialist histories of such gatherings?
