What I want to do

Here are some videos documenting Lauren Sullivan, Don Blair, and Scott Eustis (with a head cold) learning and teaching and building on arduinos and breadboards and scribbling things on a whiteboard.

Kenny came around and helped out by listening to our crazy talk about doodads and gizmos. Thanks, Kenny.

Topics covered:


What's a bioindicator? basic arduino and breadboard stuff why the riffle --why a low cost water monitor with qualitative feedback what's the point? Why open source? riffle, sniffle, coqui, nymph, tadpole, odonate, (Lolliguncula?) why do we want to measure depth? Why do we want to measure depth in new orleans?

background on depth

Depth measurements based on Dan Beavers' insights into capacitance, and all the physics and discussion on this website, By Nathan Hurst, Stevie Cummings, Ken Sheridan, Darryl, and Andy Bartram

Lauren on Bioindicators

What can a nymph tell us about our water, or what can the riffle tell us?

Scott Sleepily explains the sensor to Kenny, and subsidence in new orleans

Scott and the temp sensor

Lauren and Don are excited

Arduino and 555 for depth and temperature sensors

Mega Ohms to make sounds audible

Questions and next steps

What kinds of videos could be done for Science TV?

What would Nathan Do?

thanks for putting in a good note on bioindicators! I love benthic macroinvertebrates-- I think its the most clever way to monitor water quality.
