FireHero: Raspberry Pi Controlled Pyrotechnics
C Frank0 stashed this in Raspberry Pi
To put on a live pyrotechnic show at a music festival, Chris built the FireHero 3. The result is remotely controlled flames shooting up to 100 feet in the air.
The system is controlled by a Raspberry Pi and an Arduino. A server runs on the Pi and allows a remote computer to control the system. The Pi sends commands over serial to the Arduino, which switches solid state relays that actuate the valves.
