Gothcon is a goth themed dance party at the DEF CON 34 hacker convention in Las Vegas, on Saturday, August 8th. This badge is a fundraiser for the party -- the party is free and receives no funding from DEF CON or any source besides this one. Having a badge is not required to attend the party (though you do need a DEF CON badge since it is inside the DEF CON convention grounds), it's just a cool thing to wear around con \u0026amp; help support our ability to put on the show.\u003c\/p\u003e\n\u003cp\u003eThis year's badge is a custom PCB LED badge. It's in the shape of the bat from the Gothcon logo, with 44 LEDs around the edges. \u003c\/p\u003e\n\u003cp\u003eFeatures:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e44 independently-controlled RGB LEDs\u003c\/li\u003e\n\u003cli\u003e2000 mAh Li-Po battery able to run the badge for 24-36 hours\u003c\/li\u003e\n\u003cli\u003eUSB-C recharging with overcharge protection\u003c\/li\u003e\n\u003cli\u003eLibrary of LED patterns \u0026amp; colors, independently selectable.
