Adventures in E-Textiles.
In honor of our "Textile Messages" symposium tomorrow, I made a special, fading, Poppy Necklace. The lights on each flower are sewn in parallel and connected to the Lilypad Simple Board. Using ModKit Alpha (beta doesn't have variables yet), I programmed them to fade with the analogwrite command and adding 5 points to the brightness scale (from 0-255).
I used layers of felt to keep the circuits insulated from each other - a handy trick that also added some solidity to the otherwise thin felt. In a nod to Leah Buechley's writing about moving from the invisible to the visible in engineering, I'm showing a picture of the back. As you may guess, a lot is insulated between the layers, but you can see the final circuit completed by connecting the smallest flower to the pins on the Lilypad that power it.
