Gadget Freak Case #177: Better than a Lazy Susan

Dustyn Roberts' project, Not Lazy Susan, comes from her book, "Making Things Move." In this project Dustyn takes the Lazy Susan concept and turns it into a rotating platform with hidden qualities. To make things interesting, she uses an infrared (IR) LED and phototransistor to make the table rotate with just a wave of a hand. You can use this as a table to magically serve food to dinner guests, or to make a fun interactive centerpiece.
