What Does It Do?The Coqui: a simple device to read a sensor via an audible tone. We're exploring using audio frequencies to convey sensor readings -- like a modem, but even simpler -- in order to make sensor readings more accessible for people (or to enable data transmission over ubiquitous audio jacks on PCs and smartphones). Latest versionThe latest and simplest version of the Coqui can be seen in the following images. This version differs from the previous in a few ways:
However, the circuit is fundamentally the same!

The Coquí is a circuit that allows you to 'hear' the readings from various sensors. Once the Coquí is assembled, you'll be able to 'hear' the conductivity of a solution, the temperature of a room, or the color of a pH test strip. The design was named (onomatopeically) after the several species of small frogs which have a loud, distinctive call at night. Demo Coqui applicationsBuilding your own Coqui

What Does It Do?The Coqui: a simple device to read a sensor via an audible tone. We're exploring using audio frequencies to convey sensor readings -- like a modem, but even simpler -- in order to make sensor readings more accessible for people (or to enable data transmission over ubiquitous audio jacks on PCs and smartphones). Look for recent updates on Public Lab here. Latest versionWe'll be posting an update soon but the latest and simplest version of the Coqui can be seen in these images: ActivitiesThis is a list of community-generated guides for specific applications using your coqui. These activities can be categorized, and some may be more reproduced -- or reproducible -- than others. Try them out to build your skills, and help improve them by leaving comments. Together, we can repeat and refine the activities into experiments. [activities:coqui] Frequently Asked Questions[questions:coqui] A Coqui is a simple, inexpensive, open source device that generates an audible tone that is based on any electric resistance-based measurement. For example, a Coqui can measure:
Build a CoquiInstructions on the breadboard-based "BBv1.0" edition of the Coqui can be found here: http://publiclab.org/notes/donblair/09-30-2014/coqui-bbv1-0 Notes
The Coquí is a circuit that allows you to 'hear' the readings from various sensors. Once the Coquí is assembled, you'll be able to 'hear' the conductivity of a solution, the temperature of a room, or the color of a pH test strip. The design was named (onomatopeically) after the several species of small frogs which have a loud, distinctive call at night. Demo Coqui applicationsBuilding your own Coqui
