CMP-DIV Video Effecter - Vidiffektor

I came across an old post on Electro-Music for a video effects box.

It looks very cool
Credit for this goes to James Schidowsky.
His website is here:

The info in the post is very clear with lots of schematics and even a breadboard.
The parts count is very low.
Just two ICs ... a LM339 quad voltage comparator and a CMOS 4040
Should be a fun DIY build.

I've ordered some parts and will document the build on this page.
