The cyborg pumpkins have arrived! Stick this diffuser into your pumpkin's flesh and jam some 5mm LED's in one, some, or all of its seven sockets. Power up and have fun.This zip file includes Arduino code for a 14-LED animated eyeball display.Tips, construction pix, LED animation video, and my recipe for Szechuan Pumpkin Seeds at: http://bit.ly/RqCWWk No assembly necessary. Just print in white plastic and insert one or more LED's. This diffuser should look good in most medium-sized pumpkins.A little dab of hot glue will help keep the LED's in place if you're doing a bunch of wiring inside your pumpkin.
