element14 Community offers Halloween Treat: scary special effects powered by Raspberry Pi

Halloween door incorporates PiFace™ Digital, LCD screen and air pistons to spook trick-or-treaters

October 31, 2013 – LONDON – The award-winning and first-of-its-kind element14 Community has posted a video and step-by-step guide on using the Raspberry Pi and PiFace Digital in a visual effects application. The PiFace Halloween Effects Door is the focus of the project, but several other frightening prop ideas, and their components, are suggested as well.

The Halloween Effects Door involves, among other items, a storm door, sheet metal, a 24-inch LCD screen, six air pistons, two Raspberry Pi Model B units, a PiFace Digital and two Raspberry Pi 8Gb SD Cards pre-loaded with NOOBS.

One Raspberry Pi controls the LCD which is positioned in the window of the storm door. Once triggered by a break-beam device, the screen displays eerie visuals that give the impression someone is banging their face into the window of the door.

The other Raspberry Pi and PiFace Digital control the air pistons, which then fire against the door. The result is a startling sequence of sight and sound resembling someone or something trying to break through.

In addition to the Halloween Effects Door, users can use similar materials to create moving objects, simulate eyes in a forest or display spooky images when trick-or-treaters trigger a sensor. Additional details on the Halloween Effects Door and the other suggested builds can be found at element14.com.
