R&D-I-Y is a web platform for mass collaboration. Together, our community is working to integrate personal scale innovation for environmental stewardship + quality of life into the existing infrastructure of cities. We are applying open source software development techniques to physical systems development. We are developing hydroponic systems, LEDs, solar, aquaponics, sensor systems, nutrient sources and alternative energy . . . all using open source techniques and as many readily-available materials as possible.
