Honk! You're a horrible goose. Have fun terrorizing the village with a voice-activated Untitled Goose Game costume controller.

Have your goose honk in game by honking into your goose mask! The MONSTER M4SK can act as a USB game controller, with a PDM microphone triggering it. This will send a "spacebar" signal to your computer so you can get satisfying HONK! HONK! action!
Build the M4SK into a goose mask, with bonus points for costume flippers and wings!

This project was inspired by Twitch streamer Rudeism

It's surprisingly difficult to find a proper goose mask, so we'll use paint to transform a more common duck mask.

Next, we'll prepare the MONSTER M4SK.

Quickstart

You should be familiar with the basic setup of the M4 Eyes project based on the most excellent Adafruit MONSTER M4SK guide Quickstart. Before you proceed with making your own eye pattern texture maps, be sure you've got the M4Eyes.UF2 working properly using the default Hazel eyes graphics.

As terrifying as this may seem, the first thing we're going to do is BREAK the MONSTER M4SK! It's going to be OK, though -- It was designed to be broken! That's what those little perforations on either side of the bridge are there for. We promise!

Try powering the M4SK and turning it on now and you should see it running just as normal! Here, I've got diagnostic code running, but you should see the eyes that ship on the M4SK.

For the goose mask, we'll go about it a bit differently, so no need for the lens holders.

Goose Eye / Mic Control Code

The goose eye code is similar to our typical M4SK eye code, but has a couple of small additions to allow for the microphone to trigger the spacebar over USB HID keyboard emulation.

Follow the main guide quickstart instructions to get the M4_Eyes.UF2 running, but instead use the GOOSEGAME.UF2 file linked below.

The goose_eyes.zip file has the graphics and config.eye file you'll need.

The GOOSEGAME.UF2 file has code in it for using the microphone as a trigger for the USB HID 'spacebar' press, however, we must also enable the microphone with the "voice" : true line seen in the config.eye file here.

{
  "voice"         : true,
  "eyeRadius"     : 125,
  "eyelidIndex"   : "0x00", // From table: learn.adafruit.com/assets/61921
  "pupilColor"    : [ 0, 0, 0 ],
  "backColor"     : [ 20, 10, 10    ],
  "irisRadius"    : 110,
  "irisTexture"   : "goose/iris.bmp",
  "scleraTexture" : "goose/sclera.bmp",
  "upperEyelid"   : "goose/upper.bmp",
  "lowerEyelid"   : "goose/lower.bmp",
  "left" : {
  },
  "right" : {
  }
}

{
  "voice"         : true,
  "eyeRadius"     : 125,
  "eyelidIndex"   : "0x00", // From table: learn.adafruit.com/assets/61921
  "pupilColor"    : [ 0, 0, 0 ],
  "backColor"     : [ 20, 10, 10    ],
  "irisRadius"    : 110,
  "irisTexture"   : "goose/iris.bmp",
  "scleraTexture" : "goose/sclera.bmp",
  "upperEyelid"   : "goose/upper.bmp",
  "lowerEyelid"   : "goose/lower.bmp",
  "left" : {
  },
  "right" : {
  }
}

Next, we'll embed the MONSTER M4SK and microphone in the goose mask and play!

Embed the Eyes

Cut short strips of double-stick foam tape to surround the screens of the MONSTER M4SK.

Press these into the mask, note that we'll orient the M4SK upside down, which provides access to the USB port. It also makes the default eyelid motions a bit more menacing!

Play!

Plug it into your computer's USB port and now every time you HONK the mic will detect the loud sound and send the spacebar USB key to the game, which will in turn cause your Untitled Goose Game goose to HONK!
