Surface / Media Dial (Arduino based, USB)

This device emulates the functionality of a Surface Dial, based on an Arduino Pro Micro and EC11 encoder. Can also serve as a custom volume knob or media controller. 

The Surface Dial is a great device and offers Windows integrated functionality for volume control, media player control and easy scrolling. Also custom commands can be created for each app. This is a low-cost DIY alternative to the commercial Dial from Microsoft.

Required components:
1x Arduino Pro Micro USB-C
1x EC-11 Encoder 15mm round shaft
2x Screw M4x10
Rubber feet or mat on bottom might be useful

For the design great importance was given to haptics, optics and solidity.
