Vo-LUM Control

Assembly is easy Simple Fasten base 3d printed part to the assembled board and place the 3d Printed Knob  and Concrete knob on top.   Once assemble and 

My initial design used just 3d printed PLA to act as a concrete mold.   While this was a good Idea I soon found out that Concrete and Grout Stick to everything and are difficult to separate.   To remedy this I decided to go with making a silicone master mold.   

To do this I start out with making a PLA version of the Knob with a PLA Ring to act as a mold box

Once printed I spray painted using several coats of High Fill Primer and sand the Knob down for a smooth finish.

I then poured Moldstar 30  Silicone into the cast.    I waited 2 days for a full cure. 

Once demoted simply pour concrete and wait 1 day for concrete to cure.

Boards Are in Ready for assemble

I use Hot Air and Solder Paste to reflow the board.  

The concept of Vo-LUM is to crate a HID Controller based of the Arduino Leonardo (Atmega32u4). 

Goals

1) Universally Control the Volume and Mute function on both Mac and PC (no Drivers)

2) Addressable LED to illuminate base of control knob.

3) Be hefty (Approximately 1-2 Pounds)

4) Completely USB Powered

5) Easy to duplicate and Program

//------------------Extended Goals-----------------

7) USB TypeC Interface

6) Integrate IMU / Compass for added functionality
