Zlob - Clock Divider

A great module. Its just 2HP
These aren't official build notes.
The Zlob website is here:
https://zlobmodular.com/clk-d-2/

The build docs are slightly different from my version which I think is currently under revision
 However, it works great.


the 4040 ic must be the type that can run on up to 15V.
The trannies are 2N3904



You need to solder those 5 two pin jumpers, and then connect them with a shunt/shorting block.
This version has these pins for expansion purposes. (With the 16 pin header next to it). I could also solder each of the 2 pins together, if I didn't want the future expander.

Division6 - Dual Sequencer

Looking for the perfect sequencer is like searching for the Holy Grail
It may never end. There are so many out there.

I thought this was worth a crack.
Fairly compact and cheap to build.
I was impressed with the Div 6 pocket sequencer so whynot.

These are not build notes, just some pics to help me remember the build process if I ever want to do it again. The build is quite easy.
The official notes are here:
http://division-6.com/products/dual-mini-sequencer.php

 Its all through hole. No SMD

NLC Hyperchaos Deluxe


These are my build notes for the NLC Hyperchaos Deluxe module.
It's a nonlinearcircuits eurorack  module.

It's based on the: 

NLC - Primal HyperChaos 



There are 10different CV outputs and 2gate outputs

The CV IN is associated with the CLIMAX pot which determines how high the peaks go. The module can be greatly influenced by the CV in signal and can exhibit some fairly nutty responses at times.

Use a fast PWM signal on gate input to get different operating frequencies, change to pulse width to vary


The virgin PCBs
The Rate input can be used in a few different ways:
 1. With nothing patched in the circuit operates in slow mode
 2. With a cable patched in, but its other end hanging loose, the circuit operates in fast mode. 
 3. Feed a gate signal to the Rate input and the circuit will vary between fast and slow modes (gate high = slow)
 4. Feed a fast clock signal and you can get the circuit to operate at different speeds. 

This is quite dependent upon the frequency of the incoming clock and can take some tweaking to get right. If the clock is too fast it will mainly appear to be in slow mode
NLC is as aussie as vegemite.

It's true, even synths look better on doilies.



Headers, etc




NEXT, insert LEDS.

Triple Sloth - NLC Build notes

These are my revised build notes for the Nonlinear circuits triple sloth.

It's a module in Eurorack format that contains 3 chaos circuits.
This most recent variation of the sloth is a evolution of the original 4HP sloth module I built in 2015.
It was called the super sloth back then. You could build 3 different versions of the module basically by changing the capacitors.

Andrew later came up with a 12HP version This had 3 types of sloth chaos.
It was actually 3 of the supersloths mounted behind one 12HP panel.
Notice the differing sizes of Electro caps.

The new 2017 sloth uses just 2 PCBs.

nlc Words of wisdom.

 All animals are equal, but some animals are more equal than others.


 Totally agree. Give me Gluten !!!
Live fast, Die GG ????
----------------------------------------------------------------------------------------------------------
 Back to the build.
 ICs first
DONT do this:
Wrong side !!!!.... the board was accidently reversed

Below is the correct way:
.....the side the jacks & pots are placed on IS the side with no printing on it.


The Diodes d1 & D2 need to be reversed.

Change R7  to 330K
