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. 👻

How It Works

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

Build Steps

1. 3D Print the Case
2. Design in FreeCAD
3. Include a viewing window to show the trapped spirit.
4. Add engraved Ghostbusters logo or hazard labels.
