Turn up...

Inside are an Adafruit Trinked 5V microcontroller board and a cheap rotary encoder. All in all I spend less than 20€ on this project.

Parts I used:
- Adafruit Trinket 5V, 8MHz
- 12mm rotary encoder
- 4mm M2 screw
- Micro USB cable

Follow the instructions here to wire and program the electronics. Don't worry - it's really basic stuff.

When everything is wired up, the controler acts as an usb input device wich sends out media key commands to your computer.
