DIYbio Postcards
A free micro-newsletter mailing physical postcards of community project highlights
DIYbio Postcards was a free micro-newsletter for the DIYbio community: physical postcards mailed directly to subscribers’ doors, each featuring a short list of the most interesting community work over the preceding month.
Anyone could submit an update by tweeting a short description and photo of their project tagged #diybiohi; entries were compiled and printed onto the next postcard run. Subscriptions were free and open to anyone.

Two volumes were mailed:
- Vol. 1 (January 2012) — collected submissions from November 1, 2011 to January 1, 2012.
- Vol. 2 (July 2012) — collected submissions from June 12 to July 1, 2012.

No further volumes were produced after Vol. 2 and the experimental project was closed. The micro-newsletter reached over 100 subscribers spanning six of the seven continents. Submissions included DNA extraction demos with high school students, bioluminescent algae culturing, a guide to making fluorescent yogurt, a Makerbot-based liquid-handling hack, among others.
