Electronic Ignition Box

Inspired by the military's Mini Shrike Electronic Exploder, this is an early iteration of fire control box build with safety in mind. This box allows for safe and reliable ignition downrange. It features a continuity check which will not ignite E matches, allowing the operator to know if the wires are connected and to ensure the bridge wire is severed after ignition.

The box is powered by five 18650 cells and has two screw block terminals for inserting and securing wire. There is the little button which initiates a continuity check, giving audio and visual confirmation. To fire, the protected arming switch must be flipped which activates a red light, and only then can the big red button be pressed to fire.

Box and guts, the heavy duty weatherproof case gives an extra level of comfort when operating in the snow or rain.

For the electrically inclined, a friend prepared this schematic.

Should you want to build your own, consider the following:

1. This can easily be shrunk to a handheld formfactor.

2. You can use a capacitor to rid yourself of so many batteries.

3. Clear labels can easily be embossed into the 3D printed top plate.

4. Heavy duty alligator clips for easy connections to the outbound wires.

5. A battery charge level indicator, or use a drill battery for power.
