Still relevent? #1

How does this project work? Im looking for a DIY DCO project for my eurorack and stumbled upon this but noticed its a bit older. Are you happy with it? should I get the boards fabbed and build a couple up?

Great question! I would say I am not happy with this iteration of the design. It seems to be very sensitive to power supply fluctuations. I'm actually hoping to return to this project this year to fix it up for switching power supplies. It did work great when I had an expensive linear supply, though.

If you have some analog chops, I'd definitely be open to help cleaning up the analog path for better power supply rejection. I think the digital code and DCO core is pretty solid.

I'm not aware of another juno 6/60/106-style DCO DIY eurorack project. I'm currently working on an alpha juno "DCO" (works with direct digital synthesis at 6MHz for lower aliasing), which should be done in a few months.

You might want to look at the mutable instrument braids or the "microbraids" OLED variant if you're looking for a digital/analog DIY project - of course this isn't the same as the juno-style DCO, though.

Thanks! I have looked at the microbraids and also the Neutron Orgone Accumulator as options, but this one peaked my interest more being smaller and more unique (in my opinion).

Im not sure what you mean by "analog chops".

I just meant "ability to do analog design well" :-)
