We will be soldering the CCS811 gas sensor and NeoPixel RGBW Sticks to a quarter sized perma protoboard and the Circuit Playground Express.

The mask will need to have several small holes cut into it so we can run the wires for the Circuit Playground Express and NeoPixel Sticks. We will use ordinary nylon sewing string to adhere the components to the mask. 

I've placed the Circuit Playground Express on the blank side of the mask. The other side has a small plastic air filter so we will place a single NeoPixel Stick on that side.
