SoundCamp: interested in DIY and affordable audio equipment
○●
Increasing participation in the live audio field
○●
Reveil 24hr crowd sourced daybreak broadcast
○●
We workshop this equipment in a range of settings: higher education, community, arts, festivals..
○●
We work with the mobile app Locuscast..
○●
which sends a live stream and an accurate GPS reference to the Locus Sonus soundmap
○●
Develop and collaborate on technical solutions for different situations..
○●
including where the priority it a device that is robust, reliable and easy to use
○●
The latest streamboxes are simple and resilient..
○●
with an intuitive web interface
○●
The Raspberry Pi sits in a dribox and uses the lip on the lid as a weathering detail
○●
A pair of Primo EM-172s are inset in the wall with grommets or the cable is simply taken out via a waterproof outlet under the roof
○●
They run on USB power with a 5V mains adaptor..
○●
or power over ethernet allows cheap and safe cable runs over 100m +
○●
It can run indefinitely in mixed weather off a solar panel with a large deep cycle battery
○●
This version was developed for the North Devon Biosphere Reserve and Balance Unbalance
○●
It includes a 4G router which distributes a WiFi network for workshops
○●
These are all pretty large because of the battery
○●
A small version runs off a lithium battery using a 4G dongle to connect to a mobile network
○●
These all give good stereo images based on a roughly binaural configuration
○●
Another good way to do this, which Biosphere Soundscapes have developed, is to use a Zoom portable recorder as a USB soundcard with the Pi
○●
We're currently working on adding extra preamplification for a project in Mexico streaming sounds of roosting butterflies

There is a spectrum of technical approaches from DIY / domestic scale interventions to intallations for formal research programmes, as at Cyberforest:
