Pimped Out Megaphone Helmet
Intro: Pimped Out Megaphone Helmet
Here I show how you can very simply modify a megaphone to accept 1/8" line input from an iPod, and mount the megaphone on top of a motorcycle helmet. The resulting "Mega Helmet" delivers the maximal aural stupidity allowed by law.
STEP 1: Get a Motorcycle Helmet
Get a motorcycle helmet. I picked up this Honda one at a yard sale for $5.
STEP 2: Get a Megaphone
Get a megaphone. Here I am using a Radio Shack 32-2038A 10 watt one. It is pretty loud.
STEP 3: Take Out the Guts
Remove the batteries and open the housing for the circuit board. This is accomplished by taking out 3 screws on the back of the megaphone.
STEP 4: Prepare the 1/8" Plug
Trim the ends off of two lenghts of wire. Tin them and solder to the 1/8" plug. Ground goes to the outer of the two leads (here I have made ground the red wire, oops).
STEP 5: Run Wire Into Circuit Board Housing
Remove the handle from the megaphone, drill a hole through it, and run the wires from the plug into the body of the megaphone.
STEP 6: Solder the Wires Onto the Circuit Board
Solder the wires onto the circuit board. Ground goes to "ground" and the other wire from the plug goes to "in."
STEP 7: Screw Everything Back Together
Reattach the handle to the base, and put the circuit board back in.
STEP 8: Attach the Megaphone to the Top of the Helmet
Place the megaphone on top of the helmet and attach using copious amounts of duct tape. About 1/2 roll should be enough.
STEP 9: Attach the Microphone
Put the microphone on the inside of the mouth portion of the helmet. Attach using wire. On this helmet it was really easy because there was already a mesh grill by the mouth.
STEP 10: Mount the IPod
Put the iPod on top of the helmet, like the cherry on top, and attach the 1/8" M to 1/8" M cable to the plug on the megaphone.
STEP 11: Play Softball
Go play softball wearing the helmet. It is very good for antagonizing the pitcher, and trash-talking in general. The helmet allows both for amplification of your voice, and playback of mp3s from the iPod.

This is great, you should publish a video of the project in action.
