Remember friends, always be cautious when working with fireworks.
A couple of months ago I purchased several relay boards and switching power supplies off eBay with the plan to re-use one of my original (256 megs of RAM and no mounting holes) Raspberry Pi model B computers as a sprinkler controller. The parts arrived and I set them aside expecting to have time to work on the project after the 4th of July. About two weeks before the 4th though I realized if I got the project assembled in time I could use the sprinkler controller as a fireworks controller.
In the past I’ve had a rather cumbersome setup for controlling fireworks which required dragging out lots of different components. I actually haven’t done computer controlled fireworks for several years because there were just too many things to drag out and hook up. With the Pi I could integrate a WiFi AP, the relays, and the computer all on a small board, which would make it much easier to setup outside.
