Im not an expert in electronics (but working on it slowly, kind of know lots of bits but not enough to build anything from scratch) and i was wondering if any of you could help put any examples of this?
maybe this? May be a bit overkill, but the case doesn’t need to be that big. Plus, it could probably work just fine on the Werkstatt +/-9V power rails. Looks like R4 will need to be adjusted, but that’s it.
