Wow. You did a much better job with a box than I did. This last independence day, I built my third wireless fireworks igniter. You are right about the thicker nichrome working better. The way I did it was with 22 gauge wire coiled about a quarter inch in diameter. I can put the fuse right inside the coil and it works every time. One more thing you should add: a car horn alarm system. Sweet launcher Zinefer!
