Introduction
Astra: Safely Launch Fireworks with Raspberry Pis
Astra is an innovative application designed to simplify and enhance the process of launching fireworks for special events, such as the annual 3rd of July finale show. With Astra, you can automate the ignition of aerial mortars, eliminating the need for manual wick taping and ensuring a safer and more captivating fireworks display. What sets Astra apart is its utilization of affordable Raspberry Pi systems, making automated firework systems accessible to the general consumer.
Key Features and Benefits
User-Friendly Interface: Astra provides a simple shell script interface that allows users to visualize and manage the available fireworks for firing.
Manual and Sequential Firing: Users have the flexibility to manually fire fireworks one by one or generate a sequence for automated ignition. With the sequence functionality, Astra ensures that fireworks are launched in a planned order, reducing the risk of clashes and rebounds.
Cost-Effective Solution: By leveraging inexpensive Raspberry Pi systems and Pyroboom's Red Dragon igniters, Astra offers an affordable alternative to expensive automated firework systems, making it accessible to a wider range of users.
