Hi there,
thought I share my small design/project thats now in a good state.
I created a small (10x6x2 cm) DAW controller with 4 faders and 6 Buttons everything based on a custom designed Trill Flex boards with Arduino, standard LEDs and a 3D printed and foiled housing.
Took some time but was lot of fun, software is not finished but working, I am using it for Cubase and mainly to control VST instruments and transport.
If there is interest I can share the KiCAD files and 3D printer files.

It has three pieces, one with the Boards

one with the LEDs

and the Flex Board
Originally I wanted to build a wooden case, but that was to hard for me ;-)
If there are questions or ideas, just let me know!
