DIY GHOST Trap(Halloween)

Description

When I was a kid, Ghostbusters was my favorite movie. Every time I saw that scene where they opened the trap — blue light bursting out, eerie sounds, and spirits getting sucked inside — I promised myself that one day, I would build one for real. And now, with UNIHIKER, transparent LCD displays, and 3D printing, it’s finally possible to make that dream come true — a Ghost Trap that actually looks like there’s a real spirit inside, moving and trying to escape.

Step 1: Designed

How It Works

• Raspberry Pi plays looping “ghost-in-the-box” videos using mpv.
• The transparent display creates the illusion of a trapped entity.
• RGB LEDs flash blue-red when the ghost moves.
• Eerie knocks and whispers come from the speaker.
• When the user touches the screen → the ghost calms down briefly before reappearing.

Build Steps

• 3D Print the Case
• Design in FreeCAD
• Include a viewing window to show the trapped spirit.
• Add engraved Ghostbusters logo or hazard labels.

Step 2: Hardware

Step 3: Software

Python:

sudo nano ghost1.py

Raspberry PI: Install

pip install moviepy

sudo apt install -y mpv python3-evdev

sudo XDG_RUNTIME_DIR=/run/user/$(id -u) python3 ghost1.py

sudo -E python3 ghost1.py
