This is my first attempt to make a jog wheel with gear reduction for usage on a custom DJ midi controller.

The center window was designed to fit a small 2.4 TFT display installed on an arduino UNO emulating the display mainly seen on Pioneer most advanced DDJs.

This is not ready for usage yet as I'm working on a second version with supports for electronic components and to be fixed on a plain surface as on a MDF box or acrylic sheet.
