Glowing Super Bowl helmets

These geeky Superbowl decorations glow thanks to the EL panel hack which [Becky Stern] created. It’s almost impossible to make out in this image, but the EL panels have been applied to the surface of the helmet. On the San Francisco helmet you can just make out the black connector and cord at the bottom of the F.

El panels are a lot like EL wire (but they’re flat) in that the phosphors are excited when connected to a high voltage AC supply. You can cut the panels into shapes without a problem. The technique used here is to create a black vinyl mask to go over the top of the panel. This makes cutting the panel a lot easier.

The mask sticker is made on a vinyl cutter. [Becky] is a master at using the vector tool as you can see in the video after the break. She outlined each team logo with paths to create a file which the cutter can use. From there it took several tries to get the sticker just right as the curve of the helmet distorts the logos just a bit. Once it was dialed in she stuck the vinyl on the El panel and cut around the perimeter.

The Adafruit team sure loves to use electroluminescent accents.
