This Gesture Controlled Lamp is powered by Raspberry Pi. An infrared camera is connected to the Raspberry Pi allowing the system to monitor for wand movements since the wand has an IR LED build into it. OpenCV is used to decipher the wand movements. There are a few simple gestures that are recognized to magically control the light.

“After a recent trip to Universal’s Wizarding World of Harry Potter, my daughters and I decided to create a project that could use the interactive wands from the theme park, at home, to control our own props and gadgets. We called it Raspberry Potter because it was powered with a Raspberry Pi. We demonstrated the project last year at the Minneapolis/St. Paul Mini Maker Faire and this article — Ollivander’s Lamp — is the latest extension of that project.”
