Cat Full of Ghosts - XCHGN - video exchange - build notes

Some build notes for the CFOG XCHGN video module
Some personal build notes 



Here is the link to the official CFOG page
 
Most of the parts can be 
purchased from mouser
 
 
 
 
 
 
 
 
 
 
 
This video module is Eurorack compatable, though I'll probably use it standalone.
 It's a "dirty"video mixer  that I plan to use to expand my analog video gear.
 
There is a expander module which I might build later. It connects here.

pretty sound advice :


Small video mixers are not common so this looks worth a try.
This is described as a "dirty mixer" so I expect it will distort the signals as 
I transition from one channel to the other.

The RCA connectors




DPDT : on-none-on
x 1

SPDT switch x 3
on-off-on
1k pot - linear 


Inductor

 
 a pretty easy build..



The final pic

The XCNGN (exchange) is all about getting more out of vintage analogue gear.
So what does it do?

The main features include:
    - Two x 2:1 switches to add two additional inputs to your video mixer
    - A dirty mixer for creating distortion and disruption as you transition between two video inputs
    - A passive sharpener to heighten the edges of your signal (a classic effect)
    - A loop out/bypass function to switch from direct feedback to feedback with effects instantly
