Indeed, very doable, but tedious work ;)

Here you go:

I had the schematics lying around on paper for a while now but I was
too lazy to digitize them until now. The design is completely
untested, I just ordered some boards though so we'll see.

FWIW if anyone is interrested in getting some assembled boards I might
do a small production run.
