Voodoo Sonic is a LoRaWAN-connected Voodoo doll for noise pollution stress relief. Developed by @tamberg during the MakeZurich.ch civic tech hackathon. Noise pollution is highly subjective, so measuring nightlife noise does not help, according to Zürich city officials. Therefore, this project tries to measure the anger of affected residents instead, and display the result on a map.
