New ignition system

I finally got it all hooked up today...6V lantern battery attached to an old power cord, attached to an old Estes launch system. It fires Estes igniters in under half a second. I can probably use plain 30+ gauge wire as hot wire igniters, especially for MMX motors, and fire 2 or 3 motor clusters using Estes low-current igniters. With another 6V battery hooked up, I can even fire composite motors with Aerotech Copperhead igniters. Unfortunately, the stock bulb is burned out, so I'll have to get a new one at Radioshack or something.
I gave it a nasty test today - firing an igniter in a snowstorm at 30°F. It worked great. More details in the above launch report.
