Hugely popular in the 1980s, the Boglin was creepy enough to spook anyone who laid eyes upon one.

After some invasive but brief surgery, you can make this forgotten swamp creature even more spooky by giving it some eerie eyes with the MONSTER M4SK.

See, the M4SK and Boglin were meant to be, the board fits perfectly inside of the Boglin with minimal adjustment!

Parts

Materials and Supplies

• Boglin (Unfortunately they are no longer made but can find some on Ebay and other sites)
• Hobby knife
•  Super glue (Bob Smith Industries Maxi-Cure Extra Thick works great)
• Isopropyl alcohol for surface cleanup/prep
• Marker
• 8 x 2mm width zip ties

Optional

• Velcro hook and loop fastener with adhesive backing (optional - for securing battery)
• Panavise(s) for glue drying, not 100% necessary but helps make sure components are glued together securely

To prepare the Boglin for the MONSTER M4SK, we'll have to:

• remove the original plastic eyes to make room for the M4SK
• remove and replace the tail for easy USB access

Disconnect Upper Eyelids

Remove Eye-Cheek Connections

Disconnect Lower Eyelids

Remove Eye-Nose Connection

Fix the Eyelids (if Necessary)

To access the MONSTER M4SK via usb to change the code or charge the battery, we're going to have extend the usb port and modify the Boglin so that the usb comes through its tail. To do this, we must remove some parts of the built-in tail contraption.

Remove the Tail

Reattach the Tail

Add the Boglin eye graphics and config.eye file (linked in the green button below) to your MONSTER M4SK as per the quickstart instructions.

The Boglin eyes are made from the Hazel example in the quickstart instructions but with a white scalera to mimic the original Boglin eye.

See the config file below.

{
  "boopThreshold" : 17500, // lower = more sensitive
  "eyeRadius"     : 125,
  "eyelidIndex"   : "0x00", // From table: learn.adafruit.com/assets/61921
  "pupilColor"    : [ 0, 0, 0 ],
  "backColor"     : [ 140, 40, 20 ],
  "irisTexture"   : "boglin/iris.bmp",
  "scleraTexture" : "boglin/graphic_tfts_sclera_adj_white.bmp",
  "upperEyelid"   : "boglin/upper.bmp",
  "lowerEyelid"   : "boglin/lower.bmp",
  "left" : {
  },
  "right" : {
  }
}

{
  "boopThreshold" : 17500, // lower = more sensitive
  "eyeRadius"     : 125,
  "eyelidIndex"   : "0x00", // From table: learn.adafruit.com/assets/61921
  "pupilColor"    : [ 0, 0, 0 ],
  "backColor"     : [ 140, 40, 20 ],
  "irisTexture"   : "boglin/iris.bmp",
  "scleraTexture" : "boglin/graphic_tfts_sclera_adj_white.bmp",
  "upperEyelid"   : "boglin/upper.bmp",
  "lowerEyelid"   : "boglin/lower.bmp",
  "left" : {
  },
  "right" : {
  }
}

Be sure to place the config.eye file at the root level of the MONSTER M4SK and then press the reset button to see your changes.

Prepare the USB Cable

We will need to prepare a special usb cable with a down bend so that the usb port can be extended through the tail without damaging the cable's connection or causing a disruption to the Boglin facial structure.

Position the Board

Now we'll mount the board inside of the Boglin. To do this, we will use John Park's zip tie method. First we'll have to position the board so we have the desired orientation.

Place the Zip Ties

Mount the Board

Easy USB Access

Secure the Battery Inside of the Boglin (optional)

Switch Access

And that's it! Enjoy your wonderful and delightfully creepy Boglin mod!

Going Further

Make this project even heebie-jeebier by trying out some of these ideas:

• Use a photo editor to make the eyes even more like the original Boglin eyes.
• Add a speaker to the Boglin to make it speak when it senses motion.
• Make the Boglin a BORGlin by making it move with some servo motors!
