Introduction: .50 CAL Ammo Box Firework Controller Build
My version of systemf92s Fireworks Controller. 12 channels crammed into a .50 cal ammo box. I used speaker binding post instead of spring terminals. Most of the work was put into drilling the holes and soldering. The hole top right was unused but was going to be for a power jack to charge the battery but never got the part.
The panel is brushed 20g steel with a clear coat to prevent shorts.
We have a be nice policy.
Please be positive and constructive.
