I’ve been lurking on the LZX forums a little for over a year while gradually dipping my toes into video synthesis/glitch. I also started getting into PCB design for my job over the past year or so and I’ve been looking into designing some simple eurorack video modules based around a composite video signal path in my free time. Long story short I’ve successfully made a couple passive utility boards and am now nearing the end of a project where I cram Syntonie’s CV001, an upgraded Archer Video Enhancer circuit, into 10HP (Shoutout Syntonie for making their stuff open source). Well . . . by ending I mean ordering the boards and waiting until they show up to find out where I messed up (if they work I’ll post the details).
I’m scoping out the start of a new project to occupy my time while the boards are made and I really want a way to control the RGB colors of a composite signal. The current idea is to use a composite to RGB conversion circuit, run R, G, and B into 1K potentiometers with horizontal and vertical sync untouched, then convert everything back into composite for the output. I’m looking to use the Composite to RGB circuit found in the second post here and the RGB to Composite circuit found found in the " Building Your Own RGB To Composite Converter" section here.
I’m looking for any advice here that y’all are willing to give in regards to my choice of circuits, how to make things simpler/cheaper, and how best to make everything open source. I’ve been tinkering with electronics for a while now but mostly for my career and not for the open source DIY world.
I really enjoy the back and forth here on the LZX forums (especially everything surrounding Gen3), I appreciate the technical know-how and creative touches I’ve seen on here. I hope to add some info and flair myself as my projects develop.
