Sean Hodgins is back with a new Halloween-themed project, this time using a pico projector and a Raspberry Pi Zero to display images and animations onto a mask.

It’s kinda creepy but very, very cool.

Face-changing projection mask

Sean designed his own PCB – classic Sean – to connect the header pins of a Raspberry Pi Zero to a pico projector. He used Photoshop to modify video and image files in order to correct the angle of projection onto the mask.

He then 3D-printed this low poly mask from Thingiverse, adapting the design to allow him to attach it to a welding mask headband he purchased online.

As Sean explains in the video, there are a lot of great ways you can use the mask. Our favourite suggestion is using a camera to take a photo of someone and project their own face back at them. This idea is reminiscent of the As We Are project in Columbus, Ohio, where visitors sit inside a 14-foot tall head as their face is displayed on screens covering the outside.
