Builder in Residence: Demo Day For weeks now, a room full of makers at TinkerSpace has been heads-down building hardware from scratch. Ideas turned into circuits, circuits into prototypes, and prototypes into things that actually work. Now they're ready to show you. Come see what they've built, hear the stories behind it, ask questions, and cheer them on. These folks have poured weeks of evenings into this, and having you in the room means more than you'd think. Come celebrate with us.
