The maker community at GE FirstBuild joined forces with MakerBot Thingiverse for the Third Annual Hack-A-Thon at MakerBot’s Brooklyn, NY, headquarters. Inventors, educators, and 3D printing enthusiasts worked over the weekend to “think inside the icebox” — that is, to design features and 3D print prototypes for GE’s USB- and WiFi-enabled refrigerator, ChillHub, using the MakerBot 3D Ecoystem and Raspberry Pi computers provided by Seeed Studio. Six teams of innovators experimented with ChillHub to imagine new features and new possibilities. On the line? A MakerBot Replicator Desktop 3D Printer and two rolls of filament for each member of the winning team. No small potatoes. The winning team, headed by Bryan Berger of NY Hackathons, was Food Share, a way to display and share food from your refrigerator with neighbors. Food Share can detect freshness — so no pawning off overripe fruit, unless that’s your neighbor’s thing. Food Share would lead to less food waste and maybe more community potlucks. Other inspired entries included Chiliflix, for movie recommendations based on eating habits; Fridge Pharm, for reminders to take chilled medications; Light Snack Stopper; which gates access between meals with a joystick game; and Pavlov’s Fridge, which unlocks treats when tasks are completed. Thanks to all the participants for bringing your A game, and congratulations to Food Share.
