I built this Theremin 8 or 9 years ago. I never got it working perfectly and it's been sitting on my desk unused for most of that time. Eric Hill asked to borrow it so I dusted it off, re-read the assembly/testing instructions, got it working to the point it had been before, and lent it to him for a while to continue testing and tuning. It is painted in the colours of my bedroom from when I was a kid. If the lid is tipped sideways, it is also a reference to the Voice of Fire. At the time, I think I was going to name the device the Ear of Fire or something like that.
