I don’t know if this the correct way to do it, but I’m giving away those 3 pcb. I’d prefer them used than burried under dust. It’s more or less a prototype for a video synth using very cheap-ass components. Therefore it’s more on the lofi-noisy side of things. No exotic part (maybe the NX5DV330 that can be changed for a CD4053)
I won’t recommend it for total beginner, there’s many wire and schematic readings. But probably be useful for prototyping or testing things. I made two stand alone thing with it.
