This instructable is the new and improved version of a former project i did. the old one was dumb and hardly worked. this one is cool and works every time. i CANNOT be held responsible for anything you may cause harm to and/or destroy with my detonator. so if you are a terrorist, i dont want this instructable to end up on the news after some pointless bombing where they find my detonator amongst the rubble.

on a lighter note, this detonator is awesome. not only is it easy to build, changing the batteries is a breeze and it requires no more than $25 to make. theres a video of what it does below, and eventualy i'll post a video of it in action.

Step 1: Materials

To successfully complete this project, you will need:
1 1/4 inch stereo plug (radioshack)
1 1/4 inch stereo jack (radioshack)
1 switch w/ safety cover (we only use the cover) (radioshack)
1 red momentary pushbutton switch (radioshack)
1 can of PlastiDip (hardware store)
2 medium-sized alligator clips
1 25-foot double-wire cord (radioshack)
1 3 AAA battery holder (inside a small flashlight or radioshack)
1 one-inch threaded PVC pipe (hardware store)
1 PVC end cap that fits on the pipe
1-2 tubes of epoxy putty
2 hands
1 brain
assorted tools (saw mostly)

Step 2: The Electronics

pretty straight-forward. just look at the picture.

Step 3: The Case

for this you need the PVC pipe. saw the pipe to about 4-5 inches, or whatever feels right in your hand. remember: the threaded part will have the end cap on it so measure accordingly.

Step 4: The Handle/Grip

First, stick the electronics into the pipe through the non-threaded end of the pipe (the side you cut). the safety cover of the momentary pushbutton switch should be too large to go inside the pipe. tape the switch down (for now). drill a hole in the end cap that matches the diameter of the stereo jack. stick the jack in and screw it down with the provided mounting screw (if you got it at radioshack, otherwise just use hot glue)
Next, mix up the epoxy putty so that it is a uniform color. then, spread it evenly all around the pipe. take the tape off the switch and put epoxy putty over the sides of the cover that touch the sides of the pipe. this will hold the switch in place.

When the epoxy has dried, get out your PlastiDip. i would recommend pouring some out of the can and into a bowl or something, because when you dip the detonator, almost half the can will spill over. IMPORTANT: stick something into the jack at the bottom of the detonator so that the PlastiDip wont get inside and ruin everything.

Once the above steps are completed, get ready to dip. i recommend putting a coat hanger around the switch's safety cover so that you can easily dip the detonator.

Step 5: When It's Dry...

...cut through the PlastiDip at the top of the end cap so that it can be unscrewed.

Step 6: The Cord

get your 2 wire cord. peel the wires apart on one end for about five inches, and strip the ends. solder the alligator clips to the wires. strip the other end of the wire and solder it to the stereo jack.

Step 7: DONE!!!!!!!!

congratulations, you have just built the coolest detonator EVER. go blow stuff up and try to not kill anyone. post pictures of your completed detonators/any questions in the comments if you like, or dont if you dont feel like it. have fun!!!!!!!!!!
