Inspiration
What it does
It displays a qr-code for a lightning invoice on the Website. After scanning it with Eclair Testnet on your smartphone and paying the desired amount, the server connects to a raspberry pi with MatrixCreator LEDs and turns them on for 10 seconds.
How we built it
We set up a lightning node and put a Website built with django on top of it. A python script checks for payments in the background and connects to the raspberry pi with the lightshow if money was recieved.
Challenges we ran into
Connecting through grpc did not work at the beginning We couldn't call ROS-commands on the Pi because the bashrc checks if it is sourced from an interactive session and does not set up the ROS environment if sourced from a script.
Accomplishments that we're proud of
Working prototype
What we learned
Read the official docs first
What's next for CoinBoy
Improve integration of payments into webserver to be able to pay for different Roboy services
