[sdiy] My new Moog 960 sequencer clone module project.. slowly but surely ..

[David G Dixon]

In the picture called "4.jpg" I see a whole lot of pots and switches and
jacks with conventional solder tabs, implying that there will be a whole lot
of wires attached to all of those components.  This Herculean effort could
largely be avoided by using PCB-mount pots, switches and jacks.  
 
Here's an example from a recent project of mine: a 5U Quad Function
Generator (the functional equivalent of the Intellijel Quadra and Expander,
or a Buchla 281):
 

 
The two square holes are to accommodate jacks -- I wouldn't normally put
jacks there, but I had little choice.  There are 20 other jacks on their own
PCB which are not shown, and these connect to this board via the pin headers
along the bottom.  Otherwise this board plugs into another board which
connects to all the circuitry.  The two ICs on this board are analog
switches which are controlled by two of the physical switches, and it was
convenient to put them on this board.
 
After trying this type of construction, I will never go back to hand wiring
except for the simplest of modules.  Even for simple modules, it is very
easy to make a panel PCB.

Thanks David.

 

I’m not sure to understand what you meant..

You talk about all the external wirings that will be involved to get it
working ?

Beautiful job!  However, that panel is literally crying out for a panel PCB
to eliminate what will surely be a tangled nightmare of wires.

Hi all,

 

Just to show you where I’m going so far in my Moog 960 sequencer clone
project..

I’m happy with the actual (not finished yet) results..

Here <http://www.arcenson.com/public/Moog_960_clone/>  is the link to some
pictures:

The first 2 pictures show the front panel made out from

a thin 5 mils PCB with no copper. Spray glued to the metal plate then all
punched.

The last picture shows an empty IC socket.. That’s the PIC micro who will
actually

do all the original Flip-Flop circuitry jobs..

 

I’m building two of these !

I LOVE IT !!!!!

JP
