Overview
VectorScopeMusicAddon is an open-source printed circuit board by davedarko, from the davedarko/VectorScopeMusicAddon repository on GitHub, published under the CC0-1.0 licence. It is a 2-layer board of 37.5 × 24 mm with 16 parts on 18 nets, routed with 105 tracks and 6 vias.
It is built around the OPA2192ID and JS202011JCQN. Its parts include 8 resistors, 2 connectors, 1 IC and 1 switch.

Design Notes
There's a switch to flip the x and y-axis. Due to the displays coordinate system being 0,0 top-left it means that the y-axis is mirrored or upside-down. To negate this in some way and not fiddle around with inverting signals, the switch rotates the image by 90 degrees. It might just be that one of my macbooks channels is inverted, I have to investigate.
Errata
There's an easy fix for the vectorscope having an inverted y-axis, making the oscilloscope music show upside down. I've created a software PR that rotates and mirrors the display so it's looking correct on its own. Luckily the oscilloscope mode has running its own display instance, so it is one line of code to change.

BASIC-2
There's a wonderful case design for the badge done by @softegg. To fit into the badge better, I have designed another version with no parts on the left side of the pin header and mounting holes to create a small 3D printed cover to fit the theme better. With the known fix for the inverted y-axis, I have removed the switch to swap x and y axis now.

Questions
How big is the VectorScopeMusicAddon PCB?
It measures 37.5 × 24 mm and has 2 copper layers, 1.6 mm thick.
What parts does the VectorScopeMusicAddon use?
16 parts, built around the OPA2192ID and JS202011JCQN. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the VectorScopeMusicAddon KiCad files?
From the davedarko/VectorScopeMusicAddon repository on GitHub, at the commit this page was made from: the board is KiCad PCB files - BASIC2/VectorScopeMusicAddon.kicad_pcb and its schematic KiCad PCB files - BASIC2/VectorScopeMusicAddon.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the VectorScopeMusicAddon design in my own project?
Its repository publishes it under the CC0-1.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
