MOTM

Hi everyone,

I'm building an MOTM-ized Dark Star, and I need suggestions on 
redoing the jack and pot wiring for the Stooge panel I've ordered.  
The Blacet instructions call for the jacks to be all wired together 
to a common bare ground wire, and I think changes will be 
needed for the pots as well.  Does anyone know of a 
resource/summary of the wiring changes for this module?  Other 
sources of help?

There may be instructions to this effect included with the Stooge 
panel, but since I don't have it yet I'm not sure.  

Thanks in advance!

David

Hello David,

There are no instructions with the Stooge panels.  I assume you are 
building the MOTM style kit from Blacet?  You can wire the jack grounds the 
same as the sketch in the Blacet manual.  The ground wire does not need to 
be bare buss wire, you can wire jack to jack if you like.

The now off board pots wire to the PCB in the same fashion as the on board 
pots would be.  If you look at the PCB there are 5 solder pads for each 
pot.  For the MOTMized version, the larger of the five holes are not 
used.  The pot shell that would normal be supplied with the normal Blacet 
kit attaches there.  One of the inner 3 smaller pads is marked as pin 1 
with a numeral 1.  The pad attaches to terminal 1 one the off board 
pot.  The pad beneath the # 1 attaches to terminal 2 on the pot and the 3rd 
pad attaches to terminal 3.

If you need any more info, you can email me directly if you want, and I can 
send you a pic, or small schematic of what you need to do.

David,
    There are no specific instructions with the Dark Star panel.  Some level
of DIY ability is assumed and required for these conversions from the Blacet
frac rack to MOTM format.  The pots are wired off board.  But, essentially,
they connect the same.  Electrically, there is no need to change from the
Blacet design.  However, the panels are made to support certain circuit
modifications that are detailed on Dave Bradley's web site:

I personally do not own a Dark Star.  Dave Bradley is the resident Dark Star
expert.

The last batch of motomized DSCs went out with a sheet detailing
optional "hacks" and a small bag of parts required for same.

I added a capacitor to the noise source out to center it around ground;
this probably makes it more useful for VCO modulation. Otherwise, the
noise is positively biased.
