Hi All,
I’m not planning on building this but I read all of these construction/planning with interest! ;-)
I may have missed the discussion so forgive my rambling if I have, but in case not, there are several different diameter counting dials available that could be considered in the design. While the large ones look the coolest to me, there are counting dials that are only about the same diameter as a 10 turn pot which would work well for a more compact design while still keeping the turn counting functionality. In fact, I think the small counter is slightly smaller in diameter than a standard MOTM knob. I’ve uploaded a comparison picture to photo album in this group called “Stuff by JLR” Here’s the link to the knob on Digikey’s site:

Subject: [ModularSynthPanels] Re: Living VCO
Will and I were talking about this -
We think that the two Living VCO panels worth considering are both
counting-dial (Vernier) versions; the difference being a 5U and a 7U version.
The 5U version uses the smaller knobs for all 16 controls except the three
verniers. There are no significant modifications to Jurgen's design or
suggested hook-ups. I can't quite recall, but two of the switches may be
something Will suggested, but if so, they're very straightforward additions -
of that I'm certain.
You can read about our ideas and see our panel designs here: http://www.dragonflyalley.com/constructionJHLivingVCO.htm
OK - so that's the 5U panel...
The other panel worth considering is a 7U design. If you increase the knobs to
standard MOTM size, you need 7U of space. You can implement the 7U with the
verniers off-set a bit to make more space in the "driver section" for
the switches (the design on top on our page), or you can even out the grid as
suggested by Greg James (the design below the others on our page).
In either of these cases, there's space for an extra row of jacks - so we
figured we'd build three wave-shapers into the module... a relatively
straightforward thing to do using 3 MFOS VCO pcbs for their wave-shaper
circuits.
You could implement the 7U panel without the waveshapers and extra row of
jacks.
But if you really didn't want the verniers, you could do the Rough / Fine tune
idea a-la Dave Brown.
So to re-cap - I guess here are the choices:
1. Verniers and small knobs 5U
2. Verniers and large knobs 7U, offset verniers and including waveshapers
3. Verniers and large knobs 7U, even verniers and including waveshapers
4. Verniers and large knobs 7U, offset verniers no waveshapers
5. Verniers and large knobs 7U, even verniers no waveshapers
6. No verniers, different design
