Open source sound-to-light conversion sensors for large-scale acoustic sensing and applications\n=========================================================================================================\n\nThis repository contains the code to reproduce the results in the paper *Blinkies: Open source sound-to-light conversion sensors for large-scale acoustic sensing and applications*.\n\nAbstract\n--------\n\nWe propose an open source hardware platform called Blinky, a sound-to-light conversion sensor that harvests sound power at low-rate and in a convenient manner.\nBlinkies are made up of a central processing unit connected to two microphones and a few light-emitting devices, are powered by a battery, and protected by a robust enclosure.\nDistributed in space and combined with a conventional video camera, they allow to practically sense sound power over a very large area without hassle.\nWe give a comprehensive overview of the proposed system and its potential applications.\nWe describe the hardware design and trade-offs made.\nWe provide a model for the channel between sound power measurements and signal acquired by the video camera.\nBecause each sensor is potentially affected by a different attenuation due to the channel, we propose a calibration procedure to restore the scale of the measurements.\nThe effectiveness of the calibration is validated in an experiment.\nFinally, we demonstrate sound source localization using a hundred-and-one actual Blinkies in highly reverberent environment.\n\nAuthors\n-------\n\n* [Robin Scheibler](mailto: robin[dot]scheibler[at]ieee[dot]org)\n* Nobutaka
