This project is a response to the open-ended task of designing a piece of wearable technology. The resulting sweatshirt is suited for casual use around campus or the workplace. The features implemented include with high visibility LED safety lights to address risks for pedestrians traversing high traffic areas at night, and a heating pad for comfort and pain relief. Responsive fabric buttons were crafted by hand and embedded in a collar for control, with batteries and a power supply stored in the pocket. This project explored the creation of a compact surface mount PCB for DC-DC step-down conversion without generating excess heat that could cause irritation when worn over long periods. The sewing pattern for the sweatshirt was drafted by hand then sewn with machine and hand stitching. The removable collar houses a microcontroller and power distribution board, providing an anchor for the electronic components so the sweatshirt remains machine washable.
