A while back I started working on a very simple VCO design. Basically it’s just pulled from the LM13700 datasheet but it doesn’t include a “real” cv in circuit. And since I wanted to build this circuit into a useable eurorack module at some point anyways, why not just make a PCB with a prototype area and play with it on a real board instead of just a breadboard?

Well, today the boards arrived from OSH Park. They are much better then the boards I’ve gotten from batchpcb in the past.

So now I get to build them out! Soon I’ll be able to start distributing ultra cheap VCO’s!

Three boards!:
