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

Nuremberg -part 1 - Germany - pics

 Some pics of Nurenberg Germany.
Nuremberg is the second-largest city of the German state of Bavaria after its capital Munich.
 
Spittlertorturm.
This is the old City gate in the southwest corner of the city.
 
Part of the city walls of Nurenburg.

Its culture-filled city architecture and ornate medieval buildings are exceptional,
 


 
Zum Gulden Stern
The Golden Star is the oldest sausage restaurant in the world and it is situated just 200 metres from the White Tower
 
Obelisk with a war eagle on the Upper Charles Bridge in Nuremberg

the Pegnitz River


Pont Charles
 





The Frauenkirche ("Church of Our Lady")
Built on the initiative of Charles IV, Holy Roman Emperor between 1352 and 1362. 

The bronze shrine of St Sebald. (Sebaldskirche)
 
by VISCHER, Peter the Younger
(b. 1487, Nürnberg, d. 1528, Nürnberg)

Sebaldus, was an 8th-century missionary and is the patron saint of Nuremberg.

Church of San Sebaldo (St. Sebald's Church) windows.

Along with Frauenkirche (Our Lady's Church) and St. Lorenz, it is one of the most important churches of the city, and also one of the oldest. It is located at the Albrecht-Dürer-Platz, in front of the old city hall.

Elk Electronics DIY Workshop - Video Equations

 
Some pics from yesterdays DIY electronics workshop.
 
This was a video synth build  : The Video Equations by Cat Full of ghosts
https://www.catfullofghosts.xyz/
 
The workshop was held in Wollongong , NSW, Australia.
 

All equipment & parts supplied.
 
A very easy build.
I think this is a awesome way to start DIY electronics.

If you have never soldered before, this is for you.



 
LSD ?? - :-)
 
Hako -- awesome desoldering gun !!!
 

Thanks to everyone who attended.
Such a satisfying day.
We all left with a fully functioning synth that we built ourselves.
 
My full build notes are here:


The next Electronic Music workshop will I think be held in late Sept in Wollongong ... 
Check with Elk Elektroniks for more details.

Address: Shop 266 Crown St, Wollongong NSW 2500

Thanks for organising this workshop Ed.
We all had a great time.
