When: Through Feb. 28
E-textiles, also known as wearable electronics, combine sewing with circuitry. Imagine a hat that twinkles whenever you tilt your head, or a backpack that blinks when it’s dark outside. Participants will sew a light-up cuff with a magnetic switch, create their own battery holders and switches using conductive materials, and learn how to integrate a microcontroller into their own designs. Thursdays, 3:30-5:30 p.m., Mar. 7-Mar. 28.
