[sdiy] very simple vco

OK... here's where a simpleton like me can help out.

Keep in mind, Luca asked about "a simple, almost primordial VCO", not a
"musically useful" VCO (or what the more advanced members of this community
would consider "useful").

I was in the same situation when I set out to build my suitcase synth
project.  I had wanted to get started with DIY for years, but was daunted by
the apparent complexity of most of the circuits.  (I later found that they
weren't as complicated as I thought ; )

I would highly recommend to someone in Luca's position to go ahead & build a
simple linear VCO to play around with... I've had great fun with mine!  just
the experience of building a circuit that made noise has spurred me on to
want to build more advanced circuits!  while there are certainly limitations
to the linear vs. exponential design, none of that really matters until you
build more modules anyway... ; )

Thanks for the soapbox.
