poultry in motion - part 2 - build notes

This is part 2 of my build notes for the Poultry in Motion Module.
Some parts arrived so I can move forward a bit.
 
The PIM module is a NLC eurorack multi purpose module.
It's a
VC Delay with a sync out.
Clock-divider
Clock (the PT2399 is the clock source)
VCO (with 12 suboscillator outputs)

Part 1 of the build is here:

Some NLC words of wisdom
 

 


This spotify link contains links to more of Hasil's music.
The description of his life is well worth reading.

























IF you like really bad zombie comedy movies watch this:
"Die you zombie bastards".
Hasil Adkins plays himself.
Synopsis: the serial killer-super hero has to rescue his cannibal wife  from the clutches of an evil zombie.


Back to the build...

The Cd4060
the 4060 is a 14-bit binary Ripple Counter. 
Has a built in oscillator  

 

The 74HC4040
 

and CD4040
 
4040 -  divider/ripple counter/Binary counter.
             There is an internal chain of divide by 2 circuits. The first output will have half
             the frequency of the clock, the next output will have half the frequency of that, etc etc


--------------------
Schottky diodes are for voltage protection
 
Andrew uses MBR0540 in a sod-123 package.
"Any with 30V+ and 0.25A+ ratings will
do. dot on PCB indicates CATHODE
(stripe on component).
 


---------------------------

Caps are on.



The 22pf caps.
I'm keeping the caps. but




If you want the egg timer function to be really accurate, there
are holes to install a trimpot rather than a 22pF capacitor. If doing
so leave off the 22pF between the holes and install a trimpot around
30-40pF (Tayda: A-2496 or A-2497). Tweak the trimpot with a frequency
counter to get it tight. If just using two 22pF, it is still pretty
good; I measure 16.0001 Hz (my scope needs to see over 10Hz to get a
frequency reading).
