Sparrows

Sparrows is a framework for creating small sensor devices that send their data over OSC, designed for use in artistic projects.

It consists of simple boxes that contain a wifi based ESP microcontroller, a 3D-printable enclosure and a sensor of sorts.

There is a SuperCollider interface available that automatically keeps track of sparrows in a network and responds to their data: sparrows-sc.

Fredrik Olofsson was a big inspiration in making these devices.

Features

• Easy WiFI setup via web interface (based on WifiManager)
• Sends data via OSC
• Configurable via OSC
• Buttons for restarting/starting access point
• 3D-printable enclosures (parametrically made using OpenSCAD)
• Easily compile firmware for different boards with different sensors using platformio environments
• Only send data when it changes, to keep network traffic minimal
• A simple handshake-procedure allows a device to register itself with a target (see SuperCollider-package for inspiration).
