DIY ANIMATED COFFIN - Best HALLOWEEN Spooky Prop!!

What this video covers
This tutorial walks through building a self-opening and self-closing animated coffin prop for Halloween. A slow-rotating electric motor drives the lid mechanism, and a motion sensor is integrated so the prop activates automatically when guests approach. The creator also references a companion foam coffin build tutorial for constructing the base prop itself. The result is an interactive, trigger-based yard scare suitable for greeting trick-or-treaters.
Key takeaways
- ◆A slow-rotating electric motor powers the automatic lid open-and-close action
- ◆A motion sensor hack allows the coffin to trigger only when someone walks nearby
- ◆The foam coffin body is covered in a separate linked tutorial, keeping this video focused on the animatronic mechanism
- ◆The build combines low-voltage electronics with a physical prop for an interactive yard effect
Who this is for
Home haunters and yard haunt builders who want an eye-catching, automatically triggered coffin prop without complex programming.
Materials mentioned
- • slow rotating electric motor
- • AC/DC adapter
- • foam coffin
⚠ Safety notes
Ensure all electrical connections are weatherproofed if used outdoors; secure the motor mount firmly to prevent the lid from slamming unexpectedly.

Making a real Puppet Animatronic! #fnaf
Wicked Makers' Jaimie and Jay build a life-size animatronic version of The Puppet (Marionette) from Five Nights at Freddy's 2.

Two pneumatic systems power the scare: a scissor mechanism that launches the figure forward roughly three feet, and a chest-mounted pneumatic that thrusts its arms outward for the signature jumpscare effect.
