This augmented water device was rapidly developed during an H2O hackathon in Lausanne, Switzerland. It was built by a software engineer code-named [tamberg]. His creation contained an Arduino Uno, a strip of NeoPixels, a liquid flow sensor, and a tiny lithium-ion battery attached to a cut medical tube that was re-purposed for monitoring water use.

From the looks of it, this project addressed a specific problem and went on to solve it. The initial prototype showed a quick and dirty way to monitor precious water that is literally being flushed down the drain.

To see how the device was made, click the first link posted above for a set of Instructables. Code for the device can be found on [tamberg]’s bitbucket account. A demo video of the device being tested on a sink can be seen after the break.
