Smartphone Rocket Launcher

I still haven't documented the steps yet, but I have finally made the video for this project. Check it out here:

I just launched the rocket. I had to go a couple of times to send it off. The first time I learned that you need to use an alkaline battery for it to ignite. The second time I learned that model rocket igniters are VERY finicky. The last time I was overrjoyed when it worked. I will post instructions very soon.

I finished programming the Pi and connecting and testing the hardware today. I tested just a model rocket igniter to see if it would start on fire.  After trying a faulty igniter, the second one ignited perfectly! Now all that is left to do is launch a rocket!
