I rolled with the Intergalactic Krewe of Chewbacchus for Halloween with a troupe of space vikings. If you'd like to add some LED bling to your costume, here's what you'll need:
- Arduino
individually addressable RGB LED strip
- 9V battery
battery clip
- 3, 3V coin cell batteries
- 3 LEDs of various colors
- heavy duty foil

Step 1: Helmet

Step 1: cover this puppy with heavy duty foil.

Step 2: RGB LED strip + Arduino

I added a strip of individually-addressable RGB LEDs to my helmet. The LED strip, tutorial, and code can be found on the Adafruit Industries website

Make sure you cover the strip in tape so that the aluminum foil doesn't short the circuit.

Step 3: stuff the circuit in the helmet

The LED strip is connected to an Arduino that I housed in one of the helmet's horns. I used a 9V battery to power the Arduino. I soldered a barrel jack to a 9V battery clip to make the power connection easy and secure (or you can buy one of these guys).

Step 2: Cuffs

Step 1: light up the LED

This part is really easy. The LED's positive leg (long leg) needs to touch the positive terminal of the 3V CR2032 coin cell battery, and the other leg is connected to the negative terminal (opposite side). Wrap a piece of tape around the battery and LED legs to complete the circuit and light up the LED.

Here's a great read from Evil Mad Scientists about LED throwies (among other things, the post answers the question, "do I need a resistor?").

Step 2: craft the cuff

I cut out a strip of cardboard, wrapped it in heavy duty foil, and poked the LED through the cuff. I wrapped the LED and battery in tape to make sure nothing got shorted by the foil.

Step 3: Hammer

Once you've done the cuffs, the hammer is pretty straightforward. I covered a small cardboard box in foil, jammed/taped a shampoo bottle in the bottom to make a handle, and added an LED+coin cell battery to the front to give the hammer some electronic bling. SPACE THORRRR!!

Step 4: Belt

Super easy. Just cover a belt in foil.

And I made the robe out of a bed sheet.
