I am lazy (so i built a raspberry pi fireworks launcher) pi-erwerx

For the 4th of July i was inspired to build hack a raspberry pi fireworks firing system.  I quickly hacked together a node.js websocket+pi-gpio+webpage to run on the pi and quickly wired up a relay board and batteries. Check out the video down at the bottom for the first test fire!

Pi3 and 8 channel relay board switching 9v.

home made one time use starters made of electrical tape, really thin gauge wire, cannon fuse, and gunpowder

Not having to light fireworks upclose?  Priceless
