    Ever since childhood, almost every american male has been a fan of the Batman. But you can't have the hero without the villians, right? So DC comics created fun characters such as the penguin, catwoman, bane, and of course the joker. The joker was always my favorite (and still is) so i decided to re-create his killer joy buzzer with a more "Friendly" voltage. My 9v buzzer consists of nothing more than spare parts and some cheap stuff from radioshack, so it was a relatively cheap project to make.

tools:
soldering iron w/ solder
drill
screw driver (phillips head)
glue
tape

parts:
3 batterys with connectors
electrolyctic capacitor
project box   
speaker cable
wires
momentary switch
joy buzzer
glove
belt


Note: to make this instructable i had to take apart my buzzer and then put it back together for pics, so i decided to boost the power a little bit from 1 9v to 3 9v batterys.

Step 1: Prepare the housing

To prepare the housing for the buzzer, drill a 3/8" hole in the center of the top of the box. after that drill another hole that is 1/4" big.

Step 2: Wiring (pt. 1)

the first thing to do in this step is wire all three of the batterys in series (+ to -) and insulate your connections with electrical tape. once you have done that tape our batterys together so the wires dont get in the way.

Step 3: Wiring (pt. 2)

take the positive wire from your batterys and attach that to one of the terminals in your switch. then take a couple of inches of wire and solder one end to the remaining terminal in your switch, and the other to the positive lead in your capacitor. then take the negative wire from your batterys and solder that to the negative lead on your capactor. After that solder one wire in your speaker cable to the negative lead on your capacitor, and the other to your positive lead. remember to insulate all conections with electrical tape or a similar item.

how high of a voltage could you go without hurting someone, or having a stun-gun effect/
