This looks like something I've been hoping for! When do you think it will it be available? And through which channels?

Time for an update on the Frequency Shifter project.

I finally found the time to draw schematics for the main board of the FS-1A
(second board will follow), and I have also created a second version of the
component overlay, which shows the reference designators instead of the
component values.

A few people have adressed me about this: That printing component values
makes soldering the board easier, but debugging more difficult.
And I learned the hard way that it also makes a description of adjustment
procedures so much more difficult. (I've started adjustment descriptions on
my FS-1A page, and had to use a lot of screenshots.)

So, my solution for this, and all future projects is this:

(1) Silkscreened on the board will be the component values, just as before.
It makes it so much easier to put the right components on board for
soldering them. And when the components are soldered in, most of these
labels will not be visible anymore, anyway, as they are now beneath the
components.

(2) In addition to this, I'll provide a PDF with the board layout, using
reference designators. You print this on paper, and have it available when
you're working on your board for adjustments or debugging.
