TECH

○●   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
○●   Current projects include improved preamplification; a new streambox with new hardware and software but the same basic approach, for later in 2018; a range of options for users from fully DIY to fully pre-assembled
○●   Note also that there is a range of ways to approach the streaming, including off-the-shelf commercial products eg by Barix, used by Cyberforest and JBBR
