This past February in this space we announced the Spectrum/Make DIY contest, in which we asked you to send us your best DIY projects. Now, we’re happy to announce the winner: Alan Nishioka of Redwood City, Calif. Nishioka wowed us with his computerized Etch A Sketch toy, in which he uses computer-controlled stepper motors to create spirograph patterns. Nishioka demonstrated his project at the Maker Faire at the San Mateo, Calif., fairgrounds on 19 and 20 May. Congratulations also to our four runners-up: Rogerio Dionisio of Fundão, Portugal; Kevin M. Hubbard of Issaquah, Wash.; Michael Gaspari of Racine, Wis.; and Goran Hult of Trollhattan, Sweden.
