The MIDI Mixer
The MIDI Mixer is a Bluetooth sound board designed with six buttons
and three dials that allow for the control of audio tracks.
It is driven by an ESP32 mictrocontroller on a custom PCB board designed in the program EasyEDA. The schematics and wiring diagrams are pictured below.

The enclosure was modeled in Autodesk Fusion 360 and laser cut with acrylic. The top panel was sanded in order to give it a frosted glass finish, and the other panels were spray painted translucent blue.
As part of the project, the mixer was used to perform at a party on Halloween.
My DJ logo is raster engraved on the bottom panel and filled with silver enamel.
The music was put together using the online program AudioTool. It offers a selection of drums, tone creators, and synthesizers.
