MFOS VCO, VCA and some others |
  |
|
Hello everyone. I have been making eurorack modules as a way to teach myself PCB layout. I have recently completed PCB layouts for the MFOS VCO and VCA. They are tested working, with just a couple of small mistakes (reversed pot leads mostly). They are 3u eurorack format and mount flat to the back of the panels.
I also have done a layout for the magic smoke 8k LFO, but I'm not sure if Tim is ok with me distributing it, as he hasn't answered my email yet. Similarly, I have made a layout for Michael Barton's buffered multiple, but I also don't know if I am allowed to distribute it.
Lastly, I'm 90% complete with a mixer that's a slightly simplified version of Ray Wilson's mixers (eg: 4->2 or 8->1 switchable). I'm a little short on time to finish it at the moment, but someone familiar with kicad could knock it out pretty quickly. Circuit has been tested on stripboard, but obviously no PCB yet.
Please let me know if anyone is interested in these, and I will post a link to my github which has kicad projects, digikey BOM's, interactive pick/place maps, panel drill templates, etc. |

Hello again. I got permission from all the circuit designers, so here is the github link. Right now there are only kicad files, but I can easily output gerbers or PDF's for people who prefer to etch their own.

| Been looking for a easy VCA to put together. Please pm or post the VCA if you can. Thank you. |

What format of files do you need? Right now I only have kicad board files, but I can also post gerbers, which every pcb fab should be able to take. I could do pdf if you want to etch your own, but I have never etched my own boards, so I'm not sure if the tolerances on these are reasonable for that. |

Gerber files would be best. Most likely send them out to JLC  you can pm or email me: ryan19567@gmail.com |

| Ok, Gerbers should be uploaded for everything that's ready at the github link. There's still a few minor issues here and there, but I'm working through them. Check the readme for the most up to date info. |

Thank you for sharing the layouts
I like the combination of logic functions you chose for your Analog Logic design.
Wanted to check that the inverters are separate from the logic not serial. So logic function outputs are not inverted. |
