This is dual-purpose bobbin with 30ft of high quality 4-ply conductive thread. Once the thread is gone, the bobbin doubles as a small LilyPad Protoboard. We created this small bobbin to help people get into wearable electronics without the upfront cost of buying an entire spool of thread. 10 feet of thread is enough to get a simple design stitched onto your shirt, backpack or hat.
All of the pins on the bobbin protoboard are shorted together with 10mil traces. This allows for quick and easy prototyping - all you have to do is cut the traces between holes you don't want connected! Pins are spaced by a standard, 0.1" pitch.
LilyPad is a wearable e-textile technology developed by Leah Buechley and cooperatively designed by Leah and SparkFun. Each LilyPad was creatively designed to have large connecting pads to allow them to be sewn into clothing. Various input, output, power, and sensor boards are available. They're even washable!
Note: A portion of this sale is given back to Dr. Leah Buechley for continued development and education of e-textiles.
