Introduction: Surprise Rumbling Box
Hey, guys! And Girls. The holiday season is all about giving, right? Well, how about giving a gift you can enjoy, too. This instructable will show you how to make a rumbling box to give people a jump. And when there curiosity isn't satisfied, they look in and a camera takes a picture of them. How fun is that? Please Comment! Ok, here's what you'll need:
Shown: a small box, hot glue gun, brad fasteners, thin foam, some popscicle-type sticks, a standard 1.5 volt motor, 16 wires, aluminum foil, a half of an eraser, a double AA battery, and the camera part of a disposable camera.
Not shown: tape, electrical tape, scissors, and wrapping paper.
IMPORTANT: Many of the image notes are important, so look at them all.

Step 1: Step 1
This is fairly easy. Just insert 2 brad fasteners on each side of your box. You should have 8 total.
Step 2: Step 2
Strip the ends of 8 wires, and twist them together into 2 groups of 4. A couple of mine have matal tab ends.
Step 3: Step 3
Stick the top left corner of your eraser at about a 75 degree angle on the shaft of the motor.
Step 4: Step 4
Here's where it starts getting tricky. Hot glue (or solder if you have one) the wires on the metal nubs of the motor. (see pic.). EXTREMELY IMPORTANT: Make sure there is enough wire to wrap around the little nub, otherwise, the wire WILL NOT make contact.
Step 5: Step 5
Take your popscicle sticks (mine aren't) and cut them down to size to fit comfortably in the box. (see pic.)
Step 6: Step 6
Using LOTS of hot glue I secured the motor inside on the two "popscicle" sticks and used the ends I cut off to further stabalize it.
Step 7: Step 7
Put some strong string on the mechanism of the camera that takes the shot, and wind it to prep it. Ignore the string now, it won't be needed until later. Pay very close attention to this next part. Take the wires in the back nub of the motor (from the view of the camera) and attatch 3 to the brads on the left. Do the same on the right.IMPORTANT: Scroll over the picture to see which wires get attatched where. The remaining two wires connect to opposite sides on to the remaining brads. Since the back nub went to the left brads, the remaining wire on the back nub would go to the brad on the right. And vice versa.
Step 8: Step 8
Now twist 4 more wires into groups of 2.
Step 9: Step 9
Attatch the wires to the battery securely with electrical tape, or hot glue.
Step 10: Step 10
I know I've said a lot of stuff is important, but a lot of stuff is important in this project. Anyway, this step is EXTREMELY IMPORTANT. Do the same exact thing you did with the motor only instead of connecting to another brad, the wire for the second brad goes out through a small hole you punch, next to a brad. But, only push the wire out far enough for the little copper end to stick out. Then hot glue it like that. Only, be careful how you hook up your wires. Say you hooked everything up and then it didn't work. You would have the ends of the battery switched and would have to do all that wiring over again. So, check which way you arrange the wires before you attatch them. To further clear this up, do this. Hold the battery, and on the outside of the box touch one end of one side to a brad, and the other to the other brad. If the motor spins glue it that way on the inside. If not, switch the wires and it should work that way. Then hot glue this on the inside, and test the brads from the inside.
Step 11: Step 11
Now cut a small piece of aluminum foil and put it flat against each copper part of a wire next to a brad. Tape it on. Make sure it doesn't come in contact with the brad. (see pic.)
Step 12: Step 12
Punch a small hole in the top of the box. Then extend the string for the camera and tie it in the hole. Make sure its short enough so when the box is opened it takes a picture. Sorry the pic. is sideways.
Step 13: Step 13
Remember that foam? Cut and glue a small rectangle and put it on the opposite side of the brad and aluminum foil. Then glue the foil to the foam, extending it over the brad, and being careful not to make contact. The original design I had called for the extra brads, but I guess they just helped to connect wires, so don't be alarmed when they weren't used.
Step 14: Step 14
Hooray! You've done it! Now is the fun part: wrapping! When wrapping don't make the paper to snug, otherwise the wires will make contact, and it won't be much of a surprise. Now go enjoy your wonderful box! And make sure to get that picture developed!
