To make this awesome helmet you need the following materials:
-6 meters of EL-wire and inverter (20$)
-hot glue sticks (2$)
-A4 paper (free)
-9v battery (2$)
-High luminescence LED with 300 ohm resistor (2$)
-electric wire (free)
-1mm thick graft foam
-helping hands (or whatever it's called)
-hot glue gun
-computer running windows
-pepakura viewer http://www.tamasoft.co.jp/pepakura-en/download/download.html
Step 1: Printing the Template and Cutting the Cardboard
Now put the pieces you got in a cardboard sheet and underline them.
Cut the pieces out of the cardboard sheet (keep the paper pieces if you want to make another helmet).
if you need to glue two pieces which are supposed to form an angle, with your hobby knife cut one of the piece's edge (like in the photo) than glue the two pieces together.
once you have all the pieces open pepakura to see where they are in the helmet and assemble them.
Once you have assembled all the pieces you should spray paint the helmet with a dark color.
Step 2: Apply the EL-wire
It's like sewing the wire to the helmet.
If you need to solder you EL-wire to a normal wire look in the net for some tutorials because i don't have the time to do one.
Once you finished gluing the EL-wire to the helmet go to the next step.
Step 3: Lighting Up the Eyes
than put a lot of hot glue from the inside of the helmet.
Let the hot glue cool down and than remove the 2 pieces.
the LED circuit is very easy, you need to solder a resistor to the smaller part of the LED and than a black wire to the other part of the resistor, and a red wire to the longer part of the LED. You need to make 6 LEDs.
When you made the LEDs you need to group all of the red wires and the black wires to make just 1 red wire and 1 black wire.
(it's very hard to explain in words so watch the pictures).
glue the leds in the helmet's eyes.
Step 4: Making the Helmet Wearable and Comfortable
glue 2 hooks one for each part.
add some craft foam to the interior part of the helmet to make it comfortable and to hide all the wires.
