What this video covers
VanOaksProps builds a vintage-style flashlight prop that appears to flicker on its own, themed around ghosts using it to communicate with the living. The core electronics — an ESP32 microcontroller and a 12-LED NeoPixel ring — are hidden inside a real 1960s flashlight, producing a fully randomized flicker pattern that never repeats. The build also includes a 3D modeled and printed replacement battery pack, plus a custom weathered decal designed in Illustrator and Photoshop and printed on outdoor vinyl. Free Arduino code and 3D model files are available for download, making this a highly replicable haunt prop.
Key takeaways
- ◆Uses an ESP32 and NeoPixel ring to generate randomized, never-repeating flicker effects
- ◆Electronics are concealed inside an authentic 1960s flashlight shell for maximum realism
- ◆A 3D printed battery pack replacement and custom weathered vinyl decal complete the vintage look
- ◆AI was used to help generate the base Arduino sketch, which was then customized by the creator
- ◆Free code and 3D model files are provided for download

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. The prop combines a foam-sculpted body wrapped in black velvet with a 3D-printed, painted mask sourced from a third-party sculptor. 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.
