Behold the uWave, a microwave oven that plays YouTube videos while it cooks. [Kevin] and three classmates at the University of Pennsylvania developed the project for the 2011 PennApps hackathon. It uses a tablet computer to replace the boring old spinning food display microwaves are known for. Now, an Arduino reads the cook time and sends that information to a server via its Ethernet shield. The server then searches YouTube for a video that approximately matches the cooking time, then pushed that video to the tablet to start playing. The video demonstration embedded after the break shows this, as well as the tweet that the machine sends at the beginning of the process.
