Olivier Ros has put together a short and sweet tutorial for creating your own voice-changing mask for Halloween.

Halloween: we love it!

Grab your ghostly fairy lights, hollow out your pumpkins, and hunt down your box of spooky knick-knacks — it’s Halloween season! And with every year that passes, we see more and more uses of the Raspberry Pi in haunting costumes and decorations.

Voice-changers

At the top of the list is an increase in the number of voice changers. And Olivier Ros’s recent project is a great example of an easy-to-build piece costumimg that’s possible thanks to the small footprint of the Raspberry Pi Zero.

Playdough: so many uses, yet all we wanted to do as kids was eat it.

Oliver used a Pi Zero, though if you have the mask fit it into, you could use any 40-pin Pi and an audio DAC HAT such as this one. He also used Playdough to isolate the Zero and keep it in place, but some foam should do the trick too. Just see what you have lying around.

When I said this is an easy project, I meant it: Olivier has provided the complete code for you to install on a newly setup SD card, or to download via the terminal on your existing Raspbian configuration.

You can read through the entire build on his website, and see more of his projects over on his Instructables page.

More Halloween inspiration

If you’re looking to beef up your Halloween game this October, you should really include a Raspberry Pi in the mix. For example, our Halloween Pumpkin Light tutorial allows you to control the light show inside your carved fruit without the risk of fire. Yes, you read that correctly: a pumpkin is a fruit.
