This creepy Raspberry Pi jack-o-lantern turns to face anyone who walks by
Perezenting_3D_Prints has taken Halloween decor to the next level by creating a motion-sensing, Raspberry Pi-powered jack-o-lantern that brings some life (or spooky motion) to the seasonal staple. This jack-o-lantern can move and “look” around the room as it tracks people passing by, making it a fantastic addition to any Halloween setup.
The project is mounted on a custom 3D-printed base, and its functionality comes from a collection of PIR motion sensors strategically placed to detect movement. As soon as someone walks by, the pumpkin rotates to face the direction of the motion, creating the eerie effect that it’s following the person. It’s also illuminated with LEDs, adding to the visual appeal.
The entire contraption is driven by a Raspberry Pi (likely a Pi Zero or Raspberry Pi Pico, although the exact model wasn’t specified), connected to the motion sensors, LEDs, and an MG995 servo motor that enables the pumpkin to turn. The use of a lightweight Styrofoam pumpkin keeps the motor load light, ensuring smooth motion.
Project is its versatility
While a jack-o-lantern makes for a perfect Halloween theme, the same setup could be used with other props—like a skull, bat, or crow—to match different spooky settings. The lightweight prop choice leaves room for creativity in design.
The 3D-printed base is another key element, allowing for custom designs or even variations for different themes. Though the specific 3D printer model wasn’t mentioned, any good 3D printer should be able to handle the project easily. If you’re into Halloween decorations or just want a cool Raspberry Pi project, Perezenting_3D_Prints’ jack-o-lantern is worth checking out. You can see it in action on their YouTube channel, which provides a closer look at the setup and its spooky movements.
