  SoundCamp: interested in DIY and affordable audio equipment
  Increasing participation in the live audio field
  Reveil 24hr crowd sourced daybreak broadcast
  Notes from the streambox workshop at Goethe Institute, Sofia 25 OCT 2019
  Focusrite streambox - detailed build guide







  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
