Modular Synth Panels

Hi all,

All factors of boards were considered in my design.
Quad was first thought, of course, due to Buchla's
original design. Then I though about the
implementation of my dual Borg filter. In the end it
came down to making the most flexible PCB possible for
all to implement in what system they saw fit to. 

MOTM size would limit from small panels somewhat,
Doepfer spacing was already being done by Peter at
Plan B and Dieter at Doepfer... out. So I made the
smallest PCB I could including the best set of
features I wanted "selfishly" like the extra onboard
mixer sections for CV and Audio ins. These have been
well received thankfully. 

One final note, the PCB is only 2.5 by 3.5 inches and
is the same width as a business card is long. Small
enough to meet my original goal. You can see by the
posts on electro-music that this decision has worked.
There have been dual, triple, and single formats in a
variety of shapes and sizes. I am sure there are more
too, but I do know that many boards are sitting in
everyone's large "to do" piles of PCBs. 

Many thanks to all who purchased a PCB. The project
was a great success. Electro-music got some funds to
maintain the website, we all got nice PCB's that work
without any reported bugs (yet), and my time spent has
been vindicated with a level of satisfaction from many
who have wanted a Lopass Gate in his or her modular. 

Happy holidays DIY-project-heads, Scott at B-Chamber
will have great MOTM panels for us soon!
