Music From Outer Space

I have an overwhelming urge to build another synth at the moment. I was supposed to be building a ”’theremin”’ but I just can’t find a decent enough spec for the little money I have available at the moment. I was, therefore, very happy to remember the Music From Outer Space site that has lots of analogue synth circuit boards and kits available. I’m toying with the idea of making a Weird Sound generator built into a flight case like this but building a speaker/amp into the lid for true portability.
