Public Lab Research note

AKL Mini-Maker workshops Terms 1 & 2:

  1. The kids build standard PL Coqui design
  2. Test it in various liquids.
  3. Discuss uses, Coqui limitations, water conductivity and variations due to temperature of liquid tested.
  4. Investigate various adaptations of the Coqui: A switch for measuring turbidity using photo-resistor+LED; conductivity probes; adding a temperature sensor (DHT-11).
  5. Investigate Coqui signal output, via Arduino, for activating a public installation of LED lights that can change colour and pulsate with variations in water conductivity.
  6. Investigate Coqui signal transmission to a webpage, for public viewing.


Thanks for this Nigel! I'm especially interested in hearing what the kids think about the limitations and the new ideas you come up with -- like the LEDs that change colors in public to demonstrate conductivity readings!!!

Could you tell a little bit more about what kind of group this is, and how they became interested in the Coqui? I'm not sure, but I imagine that folks who see this would like to hear that story.

Is this a question? Click here to post it to the Questions page.
