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 CaseDesign in FreeCADInclude a viewing window to show the trapped spirit.Add engraved Ghostbusters logo or hazard labels.
Step 2: Hardware
1.UNIHIKER M10 x1
2.LCD TFT x1
3.3Dprint case
4.LED RGB WS2812
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
Step 4: 3Dprint
STEP 5 : CODE
