Divide & Conquer - NLC - Build notes.

These are my build notes for the Nonlinearcircuits eurorack Divide & conquer module.
Obviously this is a clock divider.

4 different dividers:
1. /2, /4, /8, /16, /32, /64, /128, /256
2. /1.5, /3
3. /2.5, /5
4. /3.5, /7
 Its super flexible as you can patch outputs into inputs to get crazy divisions.

 Some NLC words of wisdom
Broke Down Engine and Other Troubles with Machines. This is a book by Ron Goulart.
 "Thirteen wry and terrifying tales of homo mechanicus (what we are becoming) versus the machines we have created." 1971.
I haven't read this, but it sounds a bit like The Terminator.
La Grande Bouffe is a 1973 French–Italian film directed by Marco Ferreri. "The film centers on a group of friends who plan to eat themselves to death. It satirizes consumerism and the decadence of the bourgeoisie." Wikipedia.

 ======================
Back to the build.
The CMOS chips you will need are: 4013, 4024, 4070.
They are all SOIC format.

CD 4024


The second from the left is the CD4070

I don't have any 4013s so I've ordered these:
Mouser No:
Mfr. No:CD4013BM96G4
Mfr.:Texas Instruments
Flip-Flops CMOS Dual D-Type Flip Flop
----------------------------------------------------------------------

I used 810 Ohm resistors for the LED resistors.

I ended up using these.

These rectifiers are for protection only .. against plugging the module in backwards.

If you are building lots of the NLC modules, buy these diodes in bulk. Andrew uses these in almost every project.


Soldering the headers.

I use standard 40pin male/female headers. The are cheap as chips on ebay. Cut them to size.

Jacks

The LEDs before soldering. Solder them only after you have secured the panel.
Ready to put it all together




Yes it lights up like a Christmas tree. That's a good sign.
