v1.0
See the v1-eagle branch for my first pass at this project from 2015, but note that it
is broken. I did it in Eagle, but I've switched to KiCAD since then so I'll be starting
over for v2.
v2.0
Working on the next version in the master branch. Nearly the same architecture, but
simplifying it a bit (removing VU meters) and fixing a few things I've learned from other
projects (eg: speaker level is too much for cheap audio transformers, so drop the voltage
to line level BEFORE the transformer).

Questions
What parts does the UserConsole use?
71 parts, built around the LM4881M, TL072 and LM393. 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 UserConsole KiCad files?
From the SmittyHalibut/station-console repository on GitHub, at the commit this page was made from: the board is hardware/UserConsole/UserConsole.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the UserConsole design in my own project?
Its repository states no licence, so its author keeps all rights: ask SmittyHalibut before reusing the design.
