SparkFun in Boulder, Colorado makes and sells the LiliPad Arduino, a flexible microcontroller that is designed to be installed in a fabric object. Designed by Dr. Leah Buechley, Associate Professor at the MIT Media Lab, this bendy microprocessor can even be put through the washing machine. (Buechley made this “Turn Signal Bike Jacket” with it: http://web.media.mit.edu/~leah/LilyPad/build/turn_signal_jacket.html). The LiliPad Arduino costs between ten and thirty dollars, depending on its complexity. SparkFun also sells plenty of other helpful electronic bits and pieces. “Whether it’s a robot that can cook your breakfast or a GPS cat tracking device,” they write, “our products and resources are designed to make the world of electronics more accessible to the average person.” They offer online tutorials, too.
