The Riffle

The RIffle_328 is an Atmel328-based variant of the original ARM-based Riffle water monitor, which was designed by Ben Gamari and Laura Dietz. The Riffle_328 is designed to be programmed just like an Arduino UNO in the Arduino IDE, and is compatible with most Arduino UNO software libraries. Hardware designs for the Riffle_328 are released under the CERN Open Hardware License v1.2.

Public Lab's Open Water Initiative has supported development of the Riffle_328, as well as several water monitoring sensor prototypes.

2016 Riffle_328 Status. A small order of 30 boards arrived late April 2016, and were sent to Public Lab community members as a ways of testing current hardware features and direct further development.

Bottle Enclosure

The width and height of the Riffle-ito device allows the device to fit through the mouth of a standard commercially produced plastic water bottle (20 mm).
