[Don](/people/donblair) will lead development and also act as maintainer in the [Public Lab's open hardware process](/wiki/contributing-to-public-lab-hardware). * this activity can be done by individuals or groups, but requires coordination with other developers according to the development timeline * YYYY-MM-DD public discussion on the approach * YYYY-MM-DD submit contributions by this day * YYYY-MM-DD integration of contributions * YYYY-MM-DD 1.0 release **Other Activities:** other sensor development, lots of low-hanging fruit listed here, have fun! ###Communication * We are going to kick it all off with a Live Call on [Tuesday, March 8] [1pm PT/ 4pm EST] * Email discussion will happen on [plots-waterquality list](https://groups.google.com/group/plots-waterquality), and ... * Research notes will be tagged with "riffle" [subscribe here](https://publiclab.org/tag/riffle) * Certain areas with multiple participants and supporting organizations may host local events ...
