Bring some, take some! A room full of stuff that someone doesn't want, but that might be useful to you. Think of all the spare reels of LEDs, bags of connectors, trays of multiplexers, and boxes of dev boards that lie fallow in your garage/basement/workbench/drawer/shelves/pockets. Multiply that by 250 to get the entire expected inventory of scrap among Teardown attendees. Now, imagine redistributing it all so it gets put to good use. Enter the Scrap Swap room! Bring your scrap! Take someone else’s scrap! We’ll find something to do with anything that’s left over. (Use good judgment - e.g., no toxic waste.)
