My son came across "Wrench" character from watch dogs and thought it would be a really good idea for us to try and make a copy of the mask, we built this mask together and he is really happy with it - best part is that you control the eyes from any phone! If you like this project please vote for us :)

Step 1: Supplies

You will need

1- 3D printer

2- MAX 7219 LED Matrix and driver, available on EBay, Amazon, AliExpress, etc

3- Arduino Uno

4- Bluetooth module

5- Any old pair of goggles / sunglasses

6- A piece of black fabric (for the eyes

7- A piece of any mesh like fabric (also for the eyes)

Step 2: 3D Print the Mask

Step 3: Attach the Goggle Part to the Mask

the 3D printer mask had an attachment for the glasses, however this part fell apart - so we used an old pair of laser protective goggles, they fit the mask perfectly, so we took off the lenses and super glues it to the mask

Step 4: Covering the Eyes

We tried various things, 3D printed fabric, black fabric, paper, and settles on a piece of black fabric and a piece of mesh (got it from a bag that held some protective gear)

We super glued all pieces together, once done we cut out the extras

Step 5: Coloring the Spikes

Step 6: Electronics

We followed the above simple schematics to connect the Arduino to the BT modules and the LED matrix

Step 7: Testing to Make Sure Everything Is Working Fine

Step 8: Code

Step 9: Bluetooth

You can install any of the Bluetooth test apps, the code I have has 8 different expressions, so you can send any number between 0 & 7 to change the expression - this one seems to work well

Step 10: Programming Different Faces

I found this LED Matrix Generator that we used along with the Watch Dogs 2 Cosplay guide to generate the faces, you can generate your own, IMAGES array controls the first eye, IMAGES2 controls the second eye, so make sure to enter an array for both
