Need a way to one-up your co-worker's awesome Tux desk pal? Or need a sledding buddy who won't get lost in the snow at night? This tutorial will show you how to sew a light-up Tux penguin (or any penguin, really). The example was made for a Gentoo Linux fan, but can be modified for your favorite distro (or even just as a plain penguin).
This project uses electroluminescent (EL) wire sewn into the seams of the stuffed penguin and a LilyTwinkle microcontroller to power 6 LEDs sewn onto the front. The batteries are stored in a compartment beneath the penguin, closed with a zipper.
I became interested in sewing light-up, wearable circuits around Halloween, the most obvious time of year to make clothing glow. After the holiday, I needed a non-Halloween project to work on. Eventually, I settled on a light-up stuffed Gentoo Tux penguin as a gift for a Gentoo Linux fan.
