Today I got a free AllPCB order as they seem to be giving out free PCBs again, albeit sporadically. I ordered white solder mask, just for a change… And then when I came to solder it I realised why I never order white solder mask(oof those burn marks).
It’s designed to be a flexible(solid FR4) 3340 VCO board where you can only solder up the components you need and leave out features you don’t want. It can fit behind a Kosmo or Eurorack panel or in an enclosure, which I think is really handy for a simple bench oscillator, or for someone getting into modular who doesn’t want to shell out a relatively large sum of money for a case.
I’ve been trying to get rid of a pile of massive 2W resistors that I was given which can prove to be a challenge sometimes but it worked OK here because they aren’t packed that closely together. Also I don’t have any of the nice multiturn trimmers so I had to get creative with the mounting.
The usual files are on Github as always:
