Here is a cool pyrotechnics gadget that explodes with a shower of confetti! Great for live concerts, parties, weddings, special events...you name it!
What You Need...
Prepare the Base
Drill a 1/4" hole in the center of the electrical box top. The glow-plug should fit in the hole and you need to secure it on the other side with a small, flat nut.
Drill another hole in the side of the electrical box and insert a rubber grommet (optional). Then thread the lamp cord in the box and tie a knot so the cord does not pull out.
Strip the two wires and attach a spade connector to one and after sliding on a small piece of heat shrink tubing, attach a 12-14 gauge Butt Connector (Radio Shack) to the other.
Attch the Butt Connector (+) to the connector side of the glow-plug and the Spade Connector (-) to one of the screws that hold the cover on. Attch the cover and screw it down tightly.
NOTE: The glow plug "hot" end will be on the outside of the box.
Build the Detonator Box
2. Secure the momentary switch. Run the lamp cord into the box. Strip the ends and by looking at the individual lamp cord wires determine which one you put the spade connector on. That will be the ground. Attach that to one end of the switch. Attach the negative (black) wire for the AA battery snap to the other end of the switch. Using a wire nut (or you could solder it) attach the other lamp cord wire (+) to the red (+) wire from the AA battery snap. Test it out and make sure the glow-plug lights up.
NOTE: I used the smallest Radio Shack hobby box but had to dremel some supports to get the 2-AA battery holder to fit so the next size project enclosure will probably be easier. I just liked the smaller size.
