Making Muggle Magic

Presented by: Peiper Inventions (Seattle, WA)

Every Halloween, hundreds of kids visit the Hogwarts house on Seattle’s Trick-or-Treat Street. Come see the muggle magic behind its Harry Potter-inspired special effects: check out “Moaning Myrtle,” which includes an interactive toilet with an Arduino-based combination of servos and sound systems and a 3-axis 3D cable positioning system. All components are available online and are configured via standard plug-n-play methods. The toilet itself is the User Interface. (UI) and Moaning Myrtle responds to toilet inputs.
