A fully custom five-channel audio mixer built from scratch — custom PCB, 3D printed enclosure, programmable hotkeys, and backlit controls. A project where electronics, firmware, and industrial design converge.

01 — Problem & Goal
Why build one instead of buying one?
✏️ Write this section yourself
What gap did off-the-shelf mixers leave for you? What specific functionality did you need — which audio sources were you routing, what did the hotkeys control, what made this worth designing from scratch? What were your design goals for the enclosure aesthetically?
02 — My Role
End-to-end ownership
✏️ Write this section yourself
You did everything here — PCB design, firmware, enclosure design, and assembly. Describe how you approached each discipline and what you had to learn along the way. Were there skills you developed specifically for this project?
03 — Process & Methods
From schematic to finished object
✏️ Write this section yourself
Walk through your process: schematic design, PCB layout, component selection, and any debugging challenges. Then describe the enclosure design — how you designed for the PCB footprint, controls layout, and finish quality. What design iterations did the enclosure go through?
PCB layout / bare board
Enclosure CAD / print
04 — Outcome & Results
Does it work? What did you learn?
✏️ Write this section yourself
How does the finished mixer perform in daily use? What works well and what would you improve in a revision? What did this project teach you about the intersection of hardware design, enclosure design, and embedded systems?
