Desktop Volume Mixer - DeeJ

Here is my version of a DeeJ volume mixer.

I changed the Arduino code to be able to use some mute buttons.

I also added an option to put RGB adressable LEDs thanks to FastLED library in order to indicate the state of the audio tracks (my 3D design DOES NOT support LEDs I just wanted to make it for a future upgrade or for someone who wants to make its own design with the use these LEDs.)

Installation and Setup :

if you want to know how to install and set up DeeJ you can follow the link bellow with all the instructions (there are great videos on Youtube which explain you how to do it too).

Assembly : 

In order to put the buttons in place, you'll have to heat the button's support with a heatgun to bend it then put the button on the support and fianlly put back the support in place. (I know it sounds scary, but it works although it might not be perfect).

Then you will have to put the M2 threaded insert in the base in order to close the front and back panel. Here's a good video to show you how to use them :

After that, you will have to mount the potentiometer and start soldering the components by following the schematics down bellow. 

Finally, you can secure the front and back panel using four M2 countersunk head screws and start to use it !
