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).

Durer's House - Nuremberg Germany

 Albrecht Durer's House.
Albrecht Dürer (1471–1528), Germany's most famous artist, lived and worked in this massive 5 story, half-timbered house for nearly 20 years, from 1509 onwards.
The house was built in1420. 

The House lies in the extreme north-west of Nuremberg's Altstadt, near the Kaiserburg section of the Nuremberg Castle and the Tiergärtnertor of Nuremberg's city walls
 

The Rabbit (Der Hase).
Bronze , Homage to Durer
Jurgen Goertz 1984.



This chair is a Italian Renaissance style called a Savonarola or Dante Chair.

The design comes from the ancient Roman X-shaped chair that was very popular in medieval Italy.
It is one of the oldest forms of chair or stool, with examples reaching back to the 2nd millennium  BC

NLC Product - build notes 2

 This is part 2 of the product build notes.
Its a nonlinear circuits wavefolder eurorack module.
part 1 is here;


The build so far
ICs in place.  all opamps ...TL072, 074 & LM13700


Resistors first.





Schottky diodes:
MBR0540

Andrew  uses MBR0540 in a sod-123 package. Any with 30V+ and 0.25A+ ratings will do. 
I've ordered this:
863-MBR0540T1G
On order till mid 2022 
😊
Horray... arrived !!
 

 
Its a Schotty diode/rectifier

 

We are also using 5.1V zeiners

..
 

 
....
also nine LL4148 diodes.

BC857


Pots and jacks.
I'm using 100k linear pots though Andrew reckons 50K and 200k may be ok too.
worth experimenting if you have the time.

Nice... we are done!

Cat full of Ghosts - Video Equations

These are my personal build notes for the CFOGs Video Equations synth.
Its a video synth that uses mathematics to produce the graphics.
It was designed by Robert Jordan.

The build was quite easy .. just a few hours.
Ed of Elk Elektroniks supplied all the parts so attending the workshops is a easy
way to build them.
But if you don't live close to Wollongong Australia then you can order them online.
CFOGs is based in Melbourne Australia.


+ official BOM and BUILD GUIDE:
    https://github.com/cfoge/Video_EQ
 
Some pics of the virgin PCBs

I like to start with the lowest profile components .. 
in this case the diodes


These are 5V zener diodes. There are 14 of them.

Resistors next. Start with the 100ohm ones ... there are 20 of these.

I think this is LSD
 
 
IC headers Next
 




 
I've installed the 5mHz Crystal and the push button switches. 
 
The yellow components on the left are Resistor Arrays

The jacks on the right are CV inputs.

Add the 2 Caps, the power input jack & the voltage regulators

+ Voltage regulators (series)

Then the BNC connector & 9V battery holder.

The rear of the PCB:


Pots, & LEDs

The finished product

 
The 8pin IC with a "N" is the EPROM
EPROM (erasable programmable read-only memory) is programmable read-only memory (programmable ROM) that can be erased and re-used. 
The KIT was supplied with two. One marked with a N, the other with a P.
N = NTSC
P= Pal

The 16 pined IC on the right is a Analog to Digital converter:
579-MCP3208CIP

The big chip in the centre is a 32-bit microcontroller
P8X32A-D40
 
 
 I'm using a DC 9V supply
