Leather hood with EL ribbon trim diffused behind silicone and a scale maille arm. The full "Death" costume includes a latex top, neoprene skirt and laser cut LED scythe.
The hood electronics are fairly simple. EL-ribbon, Li-Pol battery with a Sparkfun charger and 3v EL wire inverter. The EL wire is rather inefficient compared to LEDs, a full charge of the 1200 mAh battery gives only about 6 hours of glow. The inverter also makes an annoying high pitched tone that is audible in quiet environments. For future wearable projects with lights I will only be using LEDs.
