If you like fire crackers but are in a location where you can’t use real explosives this Electronic Fire Cracker project will let you simulate fire crackers. A smoke machine and some strobe lights will provide the visual effect, a speaker will be producing sound and a raspberry pi will be controlling the show. Some PIR sensors are used to sense people and trigger the effects. The design has been made very robust in a nice industrial manner. The construction is modular which would allow for easy part replacement if needed.
