The following hardware is required to use this software:

  • 3 Raspberry Pis (Can be any version of RPi, but for best results use a RPi2 or RPi3 as the database and web server and one as the master)
    My configuration is:
  • RPi 3 for database
  • RPi 2 as master
  • RPi 0 as slave
  • A decently powerful linux server used to transcode the video streamed from the RPi 2 if you want to run this 24/7
    The linux server is only necessary if you wish to stream to an online service such as
  • RPi SenseHat
  • RPi Camera Module
  • USB Microphone For best results use a Omni microphone such as this [](U9 Mini Microphone)
  • ATMega328-PU
  • A waterproof temperature sensor I use a DS18B20 and built a voltage divider to measure the resistance and calculate the temperature
  • Wires, components, breadboards and such that will be necessary to connect everything


In the future an SD card image will be available to download

To build the software yourself, see

You can’t perform that action at this time.
