LED Fire Sombrero
The name says it all - this is a sombrero, with the traditional extra wide brim and tall crown, but instead of offering shade, it is decorated with flickering LED flames.
The flame shapes are made from translucent red organza appliqués with a diffusing layer behind them. The lighting is supplied by flexible assemblies of RGB LED pixels which are animated to similate fire. The controller and battery pack are located in the top of the tall crown, and manual control switches are located near the edge of the brim.
This hat was created as an accessory for this Ghost Rider cosplay outfit.
The clips below show some of the animation patterns as viewed from the front and the top of the hat.
