SafeDragon was a project I and others made at the 2018 San Ramon Hackathon. The project was designed to help coordinate emergency services during a natural disaster.
The plan was to use an embedded computer called a DragonBoard (similar to a Raspberry Pi) as a web server. This web server would in turn run an application that would in theory allow people to use the WiFi and Bluetooth technology on their phones to communicate with it and others in the area.
It has a messaging system, central command console, alert list, and helpful tips and guides for what to do in an emergency.
All this combined led to this project winning us the hackathon, which was very exciting!
