Raspberry Pi-Powered Portrait Transforms Into Halloween Nightmare

Up your Halloween game this year with just a Raspberry Pi, motion sensor, LCD monitor, and about eight hours of your time.

Software engineer and creative prankster Dominick Marino DIYed his own “possessed portrait” using a single-board computer, pre-made videos, and a bit of code.

“I saw a few haunted portraits scattered here and there but none of them really presented much in the way of a scare, just some simple movement,” Marino wrote on his project page. “I decided to expand the idea.”

Step one: Build the picture frame.

Inside, he mounted a 19-inch LCD monitor and Raspberry Pi 3 Model B—the brains of the operation.

Marino purchased three animated “Unliving Portrait” videos from digital decorations service AtmosFX and modified some Arc Software code, automated to play any of the clips—a man, woman, and child that each turn from unassuming vignette to horrifying demon—at random.

He also added the ability to record a five-second video of his victims, and play it back to them on the screen, “so they can see their own reaction,” Marino said.

Developed to promote the teaching of basic computer science in schools and developing countries, the cheap Raspberry Pi board has become the ultimate DIY accessory.

Use it to power a wearable computer, racing robot, or Nerf Blaster that can ID its target’s face; turn it into a mini Game Boy, pocketable PC, or nostalgic arcade joystick.

Or, to attach it to a homemade picture frame to scare the crap out of visitors.

Raspberry Pi isn’t the only tech-turned-terror: One enterprising Amazon Alexa user turned the virtual assistant into a year-round Halloween horror (which also uses a Raspberry Pi…) by repurposing a three-axis talking skull.
