Last year, a third of honeybee colonies in the United States quite literally vanished. So what can be done? This is a question the organisations Open Tech Forever and Fab Lab Barcelona have been wrestling with. Their answer is a collaborative, open source effort called the Open Source Beehives project. Their partnership has generated the creation of two beehive designs that can be freely downloaded (and 3D printed) and filled with innovative sensors to log and track bee colony health using the Smart Citizen kit.
