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

wiring up 8 channels

Not having to light fireworks upclose?  Priceless

I am lazy ( so i hooked up my Amazon Echo to my z-wave devices)

Amazon announced that they are now supporting the Belkin Wemo and the Phillips Hue on the Amazon Echo.  This is great unless you already invested in a bunch of z-wave devices and gateway.  If you have a Vera Z-wave home automation gatway take a look at my Amazon-Echo-HA-Bridge on github.  It emulates a Phillips Hue to allow the Amazon Echo to turn on/off my lights/fan/stuff!


Alexa: main screen turn on.
