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" : {
}
}
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.
- Gather the micro B down plug, micro B straight jack, and usb ribbon cable.
- Open both usb ports by carefully pulling out the black tabs slightly on each port.
- Plug the usb ribbon cable into each port and close the black tabs to lock the ribbon cable in place.
- Plug the battery into the JST connection port on the board.
- Plug the micro b down side of the cable in to the micro usb port on the board.
- Lastly plug the other end of the cable into a computer to make sure the connection is good. The board should show up on your computer as a disk drive named CIRCUITPY just like before. The board could also be showing up as M4SKBOOT. If the board is not showing up at all, double check all connections.
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.
- After turning it on, stick the board inside of the Boglin and position such that eyes are visible and adjust until placement is desirable.
- Carefully flip the Boglin over, keeping the position of the board in place. Use a sharpie to mark just above and below the holes shown here to know where to place the zip ties next.
- Now remove the board from the Boglin, and flip the Boglin inside out.
- Clean the areas below and above the marks we just just made with some isopropyl alcohol.
- Place some super glue just below one of the marks of the top part of where the board will go. Place a zip tie, perpendicular to the Boglin skin and hold in place for one minute.
- Repeat with three other marks and zip ties.
- Let the zip ties sit for at least 30 minutes to dry in place.
- Place a zip tie on each other existing zip tie and push down to mount the board in place.
- Once the connections are nice and snug, check that the eyes look like they are positioned the way you want them to be.
- Cut the excess ends of the zip ties off.
- Clean off one side of the battery and place a square a velcro hook and loop fastener material on it.
- Clean the plastic circular arm piece (the side closer to where the battery is connected to the board) and place a couple pieces of the opposite velcro hook and loop material on it.
- Connect the battery to the plastic piece via the velcro.
- To turn the board on and off, you can use the switch above and to the left of the left eye.
- If you can't find the switch by feeling through the skin, you can always access the switch by going through the back of the Boglin.
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!
