@calebkraft Well, since you asked, the concept was to sew the lilypad into a Fedora so that I would have a blinking light show around the brim.
The project didn't quite turn out as lovely as I hoped, in fact it was rather ugly, and there were a few technical challenges and even bloodshed along the way but I learned a lot. The coding (to the extent there is coding) was easier than the sewing!!
Someone brought the Jeenode to my attention. It looks pretty cool, but I'll be happy never to have to use another usb to serial converter again. They have RF modules bult in though, so that makes up for it.
