Who doesn’t love Halloween? Especially since most of us are on the other end now doing the scaring instead of being a scared kid snatching up candy. Cabe wanted to create some pro haunted effects for himself and came up with a pretty cool project.
The build uses a 24″ LCD screen that is supposed to look like a window. Behind the door are a bunch of solenoid’s controlling pneumatic piston’s that really bring the video to life, making you think something is on the other side trying to get out. Everything is controlled by a Raspberry Pi, and it is triggered by a photoelectric beam sensor. The code is written in good ol’ regular c and the video is played through OMXPlayer.
Check out the video demo after the break. Source code, schematics, BOM and other details can be found on element14.
