Raspberry Pi and projectors make this house sing the Monster Mash

If you’re the type of person who decorates their house for Halloween, you may want to consider turning the whole building into a creature that sings the Monster mash, thanks to the use of Raspberry Pi and a few projectors.

Twitter user @Firr created this impressive project using two Raspberry Pis, three projectors, some speakers, and “a mess of HDMI cables”.

One Pi handles the eyes using an HDMI splitter to project the same video of moving eyes onto a pair of windows.

The second Pi does the mouth which is a custom animation created in After Effects. This also handles the audio which is output to some party speakers playing the classic song:

When we spoke to Firr they told us that a nice “all in one” variation of the project would be to use a projector with built-in speakers, so give that a consideration if you want to replicate this.

To do that Firr did say that they may be uploading a guide later, but you can get going right now using existing resources that went into this.

For the mouth the video looper project from Adafruit was used as a base. The eyes were also adapted from an Adafruit guide, this time written by Phillip Burgess.

We’ve actually featured Burgess recently for another Halloween decoration with projected eyes, this time using spherical projectors.

While the eyes can move on their own, a joystick can be added for direct control. Firr created a switch that goes between autonomous animation and direct control.
