Halloween Props: Ghoul in the box puts on a pretty good show

[Tim’s] ghoul in the box project has all the elements of a classic Halloween prop. He built it for last year’s display but we’re sure it will be a perennial favorite.

As the name implies, it’s modeled after a Jack-in-the-box toy. Fittingly, it’s decorated with bright, happy colors and includes a crank on the right side of the box. But you don’t need any man-power to make it work. Hidden in the red circle at the center of the front panel is a motion sensor. Walk in front of the box and one of two modes will be triggered. The crank may start up and a happy rendition of Pop Goes the Weasel plays. But as it nears the end of the song the tempo slows and the pitch drops as if running out of steam. It’s perfect foreshadowing for the vigorous bursting forth of the ghoul inside.

The demo after the break gives you a look at the operation, as well as the components used in the build.

One thought on “Halloween Props: Ghoul in the box puts on a pretty good show

  1. I do love a good Jack-in-the-Box prop! The second video is really interesting, it’s crazy how far things have come in just the past 3 years. The internals of this prop look a lot more technical than modern versions of the prop controllers, PIR triggers, solenoids etc.

    In fact any Hackaday readers would probably find the controllers we use for Halloween stuff pretty basic, although you can still do a lot with them. I really like this design and have been planning to build something similar for a haunt I work at that’s adding a huge circus themed area. Very cool!
