Software for the NavCoffee Twitch livestream, running on a Raspberry Pi

The livestream can be found at twitch.tv/navcoffee

This project was created by the NavCoin Core summer interns of 2018/19 to engage with the community

This repo has been created to allow community members to recreate the livestream themselves

To recreate this project you will need:

• A raspberry pi (Raspberry Pi 3 Model B was used) with Raspbian
• A usb webcam
• A breadboard and components to create a controller (If not wanting to control through software)
• A Twitch account
• A NavCoin wallet

To run your own crypto-coffee livestream (or similar), follow the instructions below:

• Clone this repo into the /home/pi/Documents/ directory of your Pi
• Open query_wallet.sh in your text editor of choice
  • On line 6 enter the address you wish to receive NavCoin donations at, into the URL
• Open stream.sh in your text editor of choice
  • On line 10 enter your stream key for twitch, be sure not to show this on stream or to anyone you don't trust
• Replace nav_qr.png with a picture of a payment request to your address, name it nav_qr.png also
• Wire up a breadboard with buttons and LEDs if you plan to use hardware to control your stream (example picture given as breadboard_example.jpg)
  • I recommend following the guide here: https://projects.raspberrypi.org/en/projects/gpio-music-box/6 if you are not familiar with the pi and electronics
• Be sure to wire the start button to GPIO pin 17, stop to 27 and redeem coffee to 22, the start LED to 6 and coffee available LED to 13
• To activate the stream run "sudo python3 controller.py" in the Documents directory and press your physical start button
• Alternatively, run "./stream.sh" and "./stop_stream.sh" to control via the terminal (controller.py is not necessary for software control, but is necessary to get up to date wallet information)

In the event of a power cut, simply rerun "sudo python3 controller.py" to activate your control board
