If you are excited about the pyrotechnic side of the holiday, checkout this project picked up by Hackaday. It is a Raspberry Pi Fireworks Control System. I would categorize this as an appreciate but don’t attempt project:
[netmagi] claims his yearly display is a modest affair, but this controller can address 24 channels, which would be a pretty big show in any neighborhood. Living inside an old wine box is a Raspberry Pi 3B+ and three 8-channel relay boards. Half of the relays are connected directly to breakouts on the end of a long wire that connect to the electric matches used to trigger the fireworks, while the rest of the contacts are connected to a wireless controller. The front panel sports a key switch for safety and a retro analog meter for keeping tabs on the sealed lead-acid battery that powers everything. [netmagi] even set the Pi up with WiFi so he can trigger the show from his phone, letting him watch the wonder unfold overhead. A few test shots are shown in the video below.
