P.C.M. Mask

Description

I'm a really stressed person. In the last few months, I realized, that some meditation music and sound frequencies can calm me down. But in a house full of "my family" it's difficult to switch off.
So I had the idea to build this Mask to isolate me a little bit from my environment. In the same time, color changing LED's will help me, to focused on the music. After this basic idea I thought, what if I try to control the LED's by my pulse, This could calm me down, if I try to slow down or change the colors with my pulse. I think my idea goes in the direction biohacking.

So let's build this thing and let’s find out if it will work.

Details

For the main processor unit, I will use an Arduino pro micro or a nano. I will not use a Bluetooth module, so no radio frequencies on my face, instead a mini mp3 module in the mask with a micro SD card will play the music. I will build my own pulse sensor, probably with an LDR and a Led. Inside the Mask I use engraved acrylic, so no one looks straight in the LED’s. The whole thing will be surrounded by foam and tissue. At the end it should be a comfortable, nice easy to wear a mask.

Components

1 × Arduino pro micro 3V 8Mhz

2 × RGB Led's

2 × Red Led's

4 × Bc337

1 × DFPlayer Mini

Little design change

I tried to build a mask with foam, I had in my workshop, but it did not block all the daylight. So I decided to buy a pair of this sleeping mask's for 6 Euros and to modify them. Now I have to wait till Wendsday.
RGB Led test with the Arduino Pro Micro

A simple sketch to test the RGB LES's
Looks promising
Driver Electronic For The LED's

Four Bc337 transistors to power the LED's. The current per color is 40mA, so I had to use these to not kill the Arduino outputs.

Here a small color test with the dot pattern.

And this will be the first test setup to control the LED's
The first parts

I used a laser cutter to build the first parts of the mask. So I can check if the Led's will fit and to see, what I will see in the mask.

Here are the first design test.
