Public Lab DIY kits

2013 Fuller Challenge Finalist Public Lab for Open Science and Technology is devoted to empowering communities and citizen scientists to monitor their own environments through the use of inexpensive DIY techniques. They host an impressive catalog of open source toolkits on their site ranging from Water Quality Sensors to Indoor Air Quality and Kite Mapping kits, all for use in their balloon- and kite-based aerial mapping systems and beyond! Their full tool archive can be found at http://publiclab.org/tools.
