Audio controller/volume mixer

My first model made by me. This is version 1 which probably needs reworks and modifications. I am working on system which will secure arduino without need for somekind of glue or cable ties.This project will allow you to controll individual volume of programs.

I recomend to print front and back panel on glass for glassy look or on textured printbed for nice textures. I printed Body
